    Model cellulose films exposed to H. insolens glucoside hydrolase family 45 endo-cellulase—the effect of the carbohydrate-binding module2005Ingår i: Journal of Colloid and Interface Science, ISSN 0021-9797, E-ISSN 1095-7103, Vol. 285, s. 94-99Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The effects of enzyme structure and activity on the degradation of model cellulose substrates were investigated by ellipsometry for the cellulase Humicola insolens GH45. The inactive variant D10N was found to adsorb at the cellulose surface but also to be incorporated into the cellulose films to an extent that depended on pH. For the native protein, the initial adsorption monitored for the inactive variant D10N was followed by enzyme-mediated degradation of the cellulose films. Again, a dependence on pH was found, such that higher pH resulted in slower enzymatic degradation. Removing the carbohydrate-binding module eliminated this pH dependence but also resulted in a decreased adsorption to the cellulose surface, and in a decreased net catalytic effect

    The effect of evaporation on Wilhelmy-type measurements of wetting tension: Is wetting equilibrium reached for cationic surfactant adsorption on mica?1997Ingår i: Journal of Colloid and Interface Science, ISSN 0021-9797, E-ISSN 1095-7103, Vol. 191, s. 264-267Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The effect of lowering of the liquid level by evaporation on the measured values of the advancing wetting tension is calculated, and is shown to be able to account for most of the change with time of the advancing wetting tension in an earlier paper (L. G. T. Eriksson et al., J. Colloid Interface Sci. 181, 476 (1996)) concerned with the adsorption of hexadecyltrimethylammonium bromide (CTAB) on mica, using rates of evaporation (≈ 0.07 mm/h) measured for that setup. With stricter evaporation control, the wetting tension hysteresis is still large after 15 h equilibration, and it is not possible, on that time scale, to record the approach to equilibrium of the advancing contact angle for the system CTAB/mica.

    Equilibrium wetting studies of cationic surfactant adsorption on mica 1. Mono- and bilayer adsorption of CTAB1996Ingår i: Journal of Colloid and Interface Science, ISSN 0021-9797, E-ISSN 1095-7103, Vol. 181, s. 476-489Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The Wilhelmy plate method was used to study the wetting bahvior of CTAB solution on mica at concentrations from 10Ä-7Å M to 3*10Ä-4Å M. A freshly cleaved mica plate shows large amplitude oscillations of the dynamic advancing wetting tension and a jump-stick behavior of the meniscus due to surfactant adsorption at the three-phase contact line. Desorption in pure water is slow. During relaxation measurements, the wetting tension reaches its equilibrium value on a timescale of several hours. The equilibrium wetting tension decreases at low concentrations, reaches a minimum at 2.4*10Ä-5Å M corresponding to a contact angle of 73ÄoÅ, and then increases (solid/liquid bilayer adsorption) up to 3*10Ä-4Å M. The solid/liquid and solid/vapor adsorption isotherms were deduced from application of the Gibbs adsorption equation, surface force, and XPS data. The solid/liquid bilayer contains 1.4-1.6 surfactant cations per mica charge site, 0.7-1.0 in the inner layer and 0.6-0.75 in the outer layer. The areas per surfactant cation are 0.48-0.68 nmÄ2Å and 0.64-0.80 nmÄ2Å.

    A comparison of three methods for the convenient determination of SDS in aqueous solutions1998Ingår i: Journal of Colloid and Interface Science, ISSN 0021-9797, E-ISSN 1095-7103, Vol. 198, s. 261-265Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Three methods for determining the concentration of sodium dodecyl sulfate (SDS) in aqueous solutions have been investigated. The first was to titrate SDS by cetyltrimethylammonium bromide (CTAB), where the endpoint (corresponding to 1:1 neutralization) was determined by measuring the potential drop between a surfactant ion selective electrode and a silver/silver chloride reference electrode. The second was to measure the endpoint of an analogous titration by following the formation of the insoluble CTAB/SDS complex with turbidimetry. The third was to measure the turbidity of a solution as a function of SDS concentration in the presence of myristyltrimethylammonium bromide (MTAB). Of these methods, which all provide a reasonable assessment of the SDS concentration, the last was certainly the fastest and most convenient, particularly for large numbers of samples.

    Micellization and adsorption of a series of fatty amide ethoxylates2001Ingår i: Journal of Colloid and Interface Science, ISSN 0021-9797, E-ISSN 1095-7103, Vol. 242, s. 404-410Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    An in-depth study of the adsorption and micellization behaviour of a series of fatty amide ethoxylates is presented. The effect of the amide bond is studied as well as variations in unsaturations in the hydrocarbon chain and in the length of the oxyethylene headgroup. Ellipsometry is used to determine adsorption on a hydrophobic silica plate while 1H-NMR self-diffusion is used to study micelle size and structure. The amide bond was found to increase the hydrophilicity of the surfactant leading to less favourable packing at the interface. The micelles formed by these surfactants were more compact, compared to alcohol ethoxylates with the same hydrophobe. Effects of unsaturations on the interfacial packing were not be observed. The micelle structure was somewhat affected by the unsaturations due to increased bulkiness of the surfactant hydrophobe.

    The physicochemical behavior of phytosterol ethoxylates1999Ingår i: Journal of Colloid and Interface Science, ISSN 0021-9797, E-ISSN 1095-7103, Vol. 213, s. 112-120Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In this work the physicochemical behavior of a series of phytosterol ethoxylates in water is presented. The influence of the length of the polyoxyethylene chain is studied. The surfactant solutions have been examined by means of birifringent microscopy, surface tension, self diffusion 1H-NMR, dynamic and static light scattering, and rheology. The surfactants with a hydrophilic chain of 10 oxyethylene units or more gave a micellar region. The CMC values were generally very low and a reverse relationship between the CMC value and the polyoxyethylene chain length was obtained. The time required to reach equilibrium surface tension was very long, more then 150 minutes. For the hydrophobic surfactants large lamellar regions appeared while for the more hydrophilic surfactants cubic and hexagonal structures were present which remained stable up to temperatures of 100°C. In the micellar region prolate aggregates were formed which showed 'ghostlike' behavior, consisting of crossliked micelles with very fast relaxation times.

    The role of surfactant head group in the dynamic emulsification process. Single surfactant systems2003Ingår i: Journal of Colloid and Interface Science, ISSN 0021-9797, E-ISSN 1095-7103, Vol. 257, s. 337-343Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    To clarify the effect of the surfactant head group on the emulsification process, dilute dodecane in water emulsions were prepared in a small flow-through cell with three surfactants which had the same hydrocarbon tail length but different head groups. The different surfactants types were (a) a nonionic, hexa(ethyleneglycol) mono n-dodecyl ether (C12E6), (b) an anionic, sodium dodecyl sulfate (SDS), and (c) a cationic, n-dodecyl pyridinium chloride (DPC), and the emulsions were prepared under the same conditions. From dynamic light scattering measurements, it was shown that the mean steady state droplet size of the emulsions (obtained after 20 min dispersion) could be related to the interfacial tension at concentrations in the region of the cmc. This result was in agreement with laminar and turbulent viscous flow theory. However, the particle size versus surface tension data for the different surfactant systems did not fall on a single line. This behavior suggested that the surfactant played a secondary role in defining the droplet size (in addition to reducing the interfacial tension) possibly through diffusion and relaxation, during deformation of the interface. In addition, it was found that the values of the equilibrium "surfactant packing densities" of the different surfactants at the oil/water interface were almost equal near the cmc, but the mean droplet size and the interfacial tension at the cmc decreased following the order DPC>SDS>C12E6

    The role of the surfactant head group in the emulsification process: Binary (nonionic-ionic) surfactant mixtures2005Ingår i: Journal of Colloid and Interface Science, ISSN 0021-9797, E-ISSN 1095-7103, Vol. 291, s. 256-262Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Dilute emulsions of dodecane in water were prepared under constant flow rate conditions with binary surfactant systems. The droplet size distribution was measured as a function of the mixed surfactant composition in solution. The systems studied were: (a) SDS-C12E6 and (b) DPC-C12E6. At a constant concentration of SDS or DPC surfactant in solution (below the CMC) the mean emulsion droplet size decreases with the increase in the amount of C12E6 added to the solution. However, a sharp break of this droplet size occurs at a critical concentration and beyond this point the mean droplet size did not significantly change upon further increase of the C12E6. This point was found to corresponded to the CMC of the mixed surfactant systems (as previously determined from microcalorimetry measurements) and this result suggested the mixed adsorption layer on the emulsion droplet was similar to the surfactant composition on the mixed micelles. The emulsion droplet size as a function of composition at the interface was also studied. The mean emulsion droplet size in SDS-C12E6 solution was found to be lower than that in DPC-C12E6 system at the equivalent mole fraction of ionic surfactant at interface. This was explained by the stronger interactions between sulphate and polyoxyethylene head groups at the interface, which facilitate the droplet breakup. Counterion binding parameter (b) was also determined from zeta-potential of dodecane droplets under the same conditions and it was found that (b) was independent of the type of the head group and the mole fraction of ionic surfactant at interface.

    Micellar interactions in nonionic/ionic mixed surfactant systems2000Ingår i: Journal of Colloid and Interface Science, ISSN 0021-9797, E-ISSN 1095-7103, Vol. 229, s. 72-81Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    To study the influence of the chemical nature of headgroups and the type of counterion on the process of micellization in mixed surfactant systems, the cmc's of several binary mixtures of surfactants with the same length of hydrocarbon tail but with different headgroups have been determined as a function of the monomer composition using surface tension measurements. Based on these results, the interaction parameter between the surfactant species in mixed micelles has been determined using the pseudophase separation model. Experiments were carried out with (a) the nonionic/anionic C12E6/SDS ((hexa(ethyleneglycol) mono-n-dodecyl ether)/(sodium dodecyl sulfate)), (b) amphoteric/anionic DDAO/SDS ((dodecyldimethylamine oxide)/(sodium dodecyl sulfate)), and (c) amphoteric/nonionic C12E6/DDAO mixed surfactant systems. In the case of the mixed surfactant systems containing DDAO, experiments were carried out at pH 2 and pH 8 where the surfactant was in the cationic and nonionic form, respectively. It was shown that the mixtures of the nonionic surfactants with different kinds of headgroups exhibit almost ideal behavior, whereas for the nonionic/ionic surfactant mixtures, significant deviations from ideal behavior (attractive interactions) have been found, suggesting binding between the head groups. Molecular orbital calculations confirmed the existence of the strong specific interaction between (1) SDS and nonionic and cationic forms of DDAO and between (2) C12E6 and the cationic form of DDAO. In the case for the C12E6/SDS system, an alternative mechanism for the stabilization of mixed micelles was suggested, which involved the lowering in the free energy of the hydration layer

    Mesoporous silica nanoparticles are an important class of materials with a wide range of applications. This paper presents a simple protocol for synthesis of particles as small as 40. nm and with a pore size that can be as large as 9. nm. Reaction conditions including type of surfactant, type of catalyst and presence of organic polymer were investigated in order to optimize the synthesis. An important aim of the work was to understand the mechanism behind the formation of these unusual structures and an explanation based on silica condensation in the small aqueous microemulsion droplets that are present inside the drops of an oil-in-water emulsion is put forward.

    Shaping of gelling biopolymer drops in an elongation flow2002Ingår i: Journal of Colloid and Interface Science, ISSN 0021-9797, E-ISSN 1095-7103, Vol. 252, nr 2, s. 297-308Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Shaping, defined as deformation in combination with gel formation of gelatine and ?-carrageenan drops in an elongation flow, was studied. The focus was to investigate the possibility of shaping and fixating small drops in the diameter range 20 to 229 ?m. In the shaping progress and the influence of experimental properties, the viscosity, temperature, and flow of the deforming fluid were examined on the final drop shape. In the experiments a hot emulsion of an aqueous biopolymer solution in silicone oil was injected into cold silicone oil where a deforming elongation flow field existed. After injection, a temperature decrease in the drops resulted in a gel formation of the biopolymer and a fixation of the deformed drop in the flow. The shape was measured and the effect on the drop aspect ratio was determined by image analysis. Over the total drop diameter range, ?-carrageenan was more ellipsoid-shaped than gelatine, with a maximum aspect ratio of 6 compared to 4 for gelatine. For small drops, around 22 ?m, it is possible to shape ?-carrageenan, but for gelatine small drops tend to be unaffected. An increase in viscosity, temperature, and flow resulted in an increase in the final fixated shape of the drops. The differences in drop deformation between the biopolymers were explained by drop-viscosity/oil differences and differences in the kinetics of gel formation. The different gel formation kinetics resulted in a short, well-defined, shaping process for ?-carrageenan, while for gelatine the process was more complex, with both deformation and relaxation present at different stages. © 2002 Elsevier Science (USA).

    Aggregation and cluster formation of a two–dimensional colloidal system consisting of 2 mm alkoxylated silica particles trapped at the air-toluene interface has been studied. This novel system allows particle interactions to be controlled by varying the length of the grafted alkyl chains; simple estimates suggest particle bond-strengths of 15 kT and 30 kT for the octadecyl and octyl coated system, respectively. Video enhanced microscopy and image analysis enabled a simultaneously study of kinetics and structure of the ensemble of clusters, in situ. The octyl system displayed a DLCA like structure, Df ≈1.45, while the octadecyl system resulted in a more dense structure, Df ≈ 1.55. The temporal evolution of the cluster-mass distribution displayed a transition point between regimes of slower and faster aggregation for both systems, which was interpreted as a transition from DLCA to convection limited cluster aggregation (CLCA).

    Orthokinetic aggregation in two dimensions of monodisperse and bidisperse colloidal systems1999Ingår i: Journal of Colloid and Interface Science, ISSN 0021-9797, E-ISSN 1095-7103, Vol. 220, s. 269-280Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Orthokinetic aggregation of colloids trapped at the air-liquid interface was studied by direct imaging in a couette cell. This method allowed us to follow the temporal evolution of both the cluster-mass distribution and the cluster structure at a shear rate where Brownian aggregation is suppressed. The interactions between the monodisperse latex particles floating at the air-water interface were controlled either by varying the electrolyte concentration or by creating a bidisperse system through addition of small particles. The results show that the clusters in all the systems are characterized by a high fractal dimension; indicating that the clusters are rearranged and densified by the shear. Kinetic analysis suggests that aggregation of the monodisperse systems mainly proceeds through homogeneous aggregation, i.e. large clusters sticking to other large clusters. The weakly aggregated monodisperse system displayed a transition from heterogeneous to homogenous aggregation of clusters with time which could be related to an incubation time. The bidisperse system, finally, with a size ratio around 10, favored a more heterogeneous aggregation between small and large clusters throughout the aggregation process; a slightly lower fractal dimension was observed compared to the strongly aggregated monodisperse system.

    Adsorption of dimethyldodecylphosphine oxide on Mica and the interaction between the adsorbed layers1991Ingår i: Journal of Colloid and Interface Science, ISSN 0021-9797, E-ISSN 1095-7103, Vol. 143, s. 573-580Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The surface force apparatus has been used to measure the interactions between two mica surfaces immersed in aqueous solutions of dimethyldodecylphosphine oxide (DDPO). In addition, contact angles of dropets, from solutions with various concentrations of DDPO, on mica surfaces which had previously been immersed in the solution were determined. The aim was to explore to what extent a nonionic surfactant adsorbes onto a polar surface such as mica. These measurements indicate that DDPO adsorbs in a stepwise manner on the mica surface by forming two successive layers. The first layer is strongly adsorbed but the second layer can be removed by applying a large enough force. An adsorption mechanism for DDPO on mica is proposed. The possibility of a weak intetaction between the electronnegative oxygen in the head group and the proton adsorbed in the mica lattice is suggested.

    Interaction between phosphine oxide surfactant layers adsorbed on hydrophobed Mica1991Ingår i: Journal of Colloid and Interface Science, ISSN 0021-9797, E-ISSN 1095-7103, Vol. 143, s. 1-8Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The surface force apparatus has been used to determine the interactions between hydrophobed mica surfaces immersed in aqueous solutions of the nonionic surfactant, dimethyldodecylphosphine oxide (DDPO) . The adsorption of surfactant on hydrophobic surfaces was studied at different concentrations. When a densely packed nonionic surfactant layer had adsorbed, the surface intetaction was measured as a function of temperature. Contact angles on hydrophobed mica sheets immersed in DDPO solutions were also recorded at different concentrations. The results show that strong, long-range hydrophobic attraction vanishes completely. In contrast, the adhesjion, as measured by the pull-off force, is substanially redused as soon as any polar groups are present on the hydrophobic surface. A repulsive hydration force is present between the nonionic DDPO head groups at short separations . There is an adhesive minimum between surfaces covered with DDPO monolayers. A temperature dependence of the interactions between the head groups was recorded and related to the temperature-induced phase separation present in the bulkDDpo.water system.

    Characterization of protein gels by scanning and transmission electron microscopy: A methodology study of soy protein gels1981Ingår i: Journal of Colloid and Interface Science, ISSN 0021-9797, E-ISSN 1095-7103, Vol. 81, nr 2, s. 519-530Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Different preparation techniques for scanning (SEM) and for transmission electron microscopy (TEM) were compared in order to characterize the structure of protein gels. SEM specimens were prepared by chemical fixation, dehydration, and critical-point drying. TEM specimens were prepared by using techniques of thin-sectioning and freeze-fracturing/etching. Thin sections were made after varying fixation and staining conditions. For freeze-fracturing/etching, the standard freezing procedure both using and omitting cryoprotectants (glycerol), as well as a particular modification of the "soil-emulsion" freezing technique without cryoprotective pretreatment were used. Finally, critical-point dried specimens (produced for SEM) were freeze-etched after infiltration with dioxane. The various techniques of preparation were applied to soy protein gels made in distilled water and in 0.2M NaCl under well defined conditions. The gel structures differed with regard to the state of aggregation which depended on the presence or absence of NaCl. The network structure was found to be of two levels. First, there was an orientation on the molecular level in the form of strands and fine ring structures. Second, there was a coarser network with voids of the magnitude of ?0.2 ?m. The pore size distribution of the latter network was found to be very sensitive to environmental factors such as low ionic strength and presence of cryoprotectants mainly due to swelling. The information obtained by the various techniques generally showed good agreement and were complementary. Distinct preparation artifacts caused by improper freezing or critical-point drying were also revealed. © 1981 Academic Press, Inc. All rights of reproduction in any form reserved.

    Wetting hysteresis induced by temperature changes: Supercooled water on hydrophobic surfaces2016Ingår i: Journal of Colloid and Interface Science, ISSN 0021-9797, E-ISSN 1095-7103, Vol. 468, s. 21-33Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The state and stability of supercooled water on (super)hydrophobic surfaces is crucial for low temperature applications and it will affect anti-icing and de-icing properties. Surface characteristics such as topography and chemistry are expected to affect wetting hysteresis during temperature cycling experiments, and also the freezing delay of supercooled water. We utilized stochastically rough wood surfaces that were further modified to render them hydrophobic or superhydrophobic. Liquid flame spraying (LFS) was utilized to create a multi-scale roughness by depositing titanium dioxide nanoparticles. The coating was subsequently made non-polar by applying a thin plasma polymer layer. As flat reference samples modified silica surfaces with similar chemistries were utilized. With these substrates we test the hypothesis that superhydrophobic surfaces also should retard ice formation. Wetting hysteresis was evaluated using contact angle measurements during a freeze-thaw cycle from room temperature to freezing occurrence at -7 °C, and then back to room temperature. Further, the delay in freezing of supercooled water droplets was studied at temperatures of -4 °C and -7 °C. The hysteresis in contact angle observed during a cooling-heating cycle is found to be small on flat hydrophobic surfaces. However, significant changes in contact angles during a cooling-heating cycle are observed on the rough surfaces, with a higher contact angle observed on cooling compared to during the subsequent heating. Condensation and subsequent frost formation at sub-zero temperatures induce the hysteresis. The freezing delay data show that the flat surface is more efficient in enhancing the freezing delay than the rougher surfaces, which can be rationalized considering heterogeneous nucleation theory. Thus, our data suggests that molecular flat surfaces, rather than rough superhydrophobic surfaces, are beneficial for retarding ice formation under conditions that allow condensation and frost formation to occur.

    Surface force studies of Langmuir-Blodgett cellulose films1997Ingår i: Journal of Colloid and Interface Science, ISSN 0021-9797, E-ISSN 1095-7103, Vol. 186, s. 369-381Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The interactions between cellulose surfaces, between chitosan coated surfaces and between one cellulose surface and one chitosan coated surface have been studied using the interferometric surface forces apparatus (SFA). The cellulose surfaces were prepared by depositing trimethylsilyl cellulose on hydrophobized mica using the Langmuir-Blodgett technique. The surfaces were desilylated in humid HCl atmosphere to obtain regenerated cellulose. ESCA measurements and wetting studies demonstrated that the desilylation process was effective. AFM studies showed the cellulose surfaces to be smooth with a root mean square roughness of 0.16 nm. Surface force and ellipsometry measurements illustrate that the cellulose film swells considerably in humid air and in water, suggesting that it is mostly amorphous. The interaction between two cellulose surfaces is dominated by a steric repulsion caused by a few dangling tails. On separation an attractive force was present both between two cellulose surfaces and between one cellulose surface and one chitosan surface. The long-range interaction between cellulose and chitosan was shown to be attractive.

    Temperature-dependent surface nanomechanical properties of a thermoplastic nanocomposite2017Ingår i: Journal of Colloid and Interface Science, ISSN 0021-9797, E-ISSN 1095-7103, Vol. 494, s. 204-214Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In polymer nanocomposites, particle-polymer interactions influence the properties of the matrix polymer next to the particle surface, providing different physicochemical properties than in the bulk matrix. This region is often referred to as the interphase, but detailed characterization of its properties remains a challenge. Here we employ two atomic force microscopy (AFM) force methods, differing by a factor of about 15 in probing rate, to directly measure the surface nanomechanical properties of the transition region between filler particle and matrix over a controlled temperature range. The nanocomposite consists of poly(ethyl methacrylate) (PEMA) and poly(isobutyl methacrylate) (PiBMA) with a high concentration of hydrophobized silica nanoparticles. Both AFM methods demonstrate that the interphase region around a 40-nm-sized particle located on the surface of the nanocomposite could extend to 55-70nm, and the interphase exhibits a gradient distribution in surface nanomechanical properties. However, the slower probing rate provides somewhat lower numerical values for the surface stiffness. The analysis of the local glass transition temperature (T g) of the interphase and the polymer matrix provides evidence for reduced stiffness of the polymer matrix at high particle concentration, a feature that we attribute to selective adsorption. These findings provide new insight into understanding the microstructure and mechanical properties of nanocomposites, which is of importance for designing nanomaterials.

    Abstract [en]

    Tetraalkylammonium and tetraalkylphosphonium ions induce oil droplet coalescence in dilute o/w emulsions stabilized by sodium dodecanoate. This was shown by both dynamic light-scattering, monitoring oil droplet sizes, and kinetical measurements of oil droplet aggregation. A large ion size, a symmetrical ion geometry and a strongly interacting counterion were found to be important criteria for organic electrolytes to be efficient emulsifiers.

    Titration microcalorimetry studies of the interaction between humicola lanuginosa lipase and ionic surfactants1999Ingår i: Journal of Colloid and Interface Science, ISSN 0021-9797, E-ISSN 1095-7103, Vol. 213, s. 262-264Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Microcalorimetry has been used to study the interaction between Humicola lanuginosa lipase and either the anionic surfactant sodium dodecyl sulfate, SDS, or the cationic surfactant tetradecyltrimethylammonium bromide, TTAB. For SDS no conclusive evidence was obtained of whether or not an enzyme-surfactant complex is formed. Although not unambiguous, the calorimetric titration curves obtained with TTAB indicate formation of such a complex.

    Carbohydrate gel beads as model probes for quantifying non-ionic and ionic contributions behind the swelling of delignified plant fibers.2018Ingår i: Journal of Colloid and Interface Science, ISSN 0021-9797, E-ISSN 1095-7103, Vol. 519, s. 119-129, artikel-id S0021-9797(18)30200-5Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Macroscopic beads of water-based gels consisting of uncharged and partially charged β-(1,4)-d-glucan polymers were developed to be used as a novel model material for studying the water induced swelling of the delignified plant fiber walls. The gel beads were prepared by drop-wise precipitation of solutions of dissolving grade fibers carboxymethylated to different degrees. The internal structure was analyzed using Solid State Cross-Polarization Magic Angle Spinning Carbon-13 Nuclear Magnetic Resonance and Small Angle X-ray Scattering showing that the internal structure could be considered a homogeneous, non-crystalline and molecularly dispersed polymer network. When beads with different charge densities were equilibrated with aqueous solutions of different ionic strengths and/or pH, the change in water uptake followed the trends expected for weak polyelectrolyte gels and the trends found for cellulose-rich fibers. When dried and subsequently immersed in water the beads also showed an irreversible loss of swelling depending on the charge and type of counter-ion which is commonly also found for cellulose-rich fibers. Taken all these results together it is clear that the model cellulose-based beads constitute an excellent tool for studying the fundamentals of swelling of cellulose rich plant fibers, aiding in the elucidation of the different molecular and supramolecular contributions to the swelling.

    Abstract [en]

    Monolayers of dodecylammonium chloride formed at the solution-air interface at different electrolyte concentrations have been investigated by dynamic surface light scattering. Pronounced maxima in the damping of capillary waves were observed at surfactant concentrations around 0.1xCMC. These maxima occur at concentrations just above the break points in the surface tension vs. concentration curves caused by first order phase transitions from a gaseous to a liquid- expanded state. The experimental results were analysed by comparing with theoretical calculations based on the standard theory of light scattering due to capillary waves on liquid surfaces, and the molecular theory of the surface tension of ionic surfactant solutions presented earlier by Eriksson and Ljunggren. In this way it was possible to account satisfactorily for the observed concentration and salt dependencies of the central frequency and width of the spectral peak.

    Interactions between adsorbed layers of a low charge density cationic polyelectrolyte on mica in the absence and presence of anionic surfactant1997Ingår i: Journal of Colloid and Interface Science, ISSN 0021-9797, E-ISSN 1095-7103, Vol. 190, s. 476-484Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Interactions between two negatively charged mica surfaces across aqueous solutions containing various amounts of a 10% charged cationic polyelectrolyte have been studied. It is found that the mica surface charge is neutralised when the polyelectrolyte is adsorbed from a 10-50 ppm aqueous solution. Consequently no electrostatic double-layer force is observed. Instead an attractive force acts between the surfaces in the distance regime 250-100 Å. We suggest that this attraction is caused by bridging. Additional adsorption takes place when the polyelectrolyte concentration is increased to 100 and 300 ppm, and a long-range repulsion develops. This repulsive force is both of electrostatic and steric origin. The polyelectrolyte layer adsorbed from a 50 ppm solution does not desorb when the polyelectrolyte solution is replaced with an aqueous polyelectrolyte-free solution. Injection of sodium dodecyl sulphate, SDS, into the measuring chamber to a concentration of about 0.01 cmc (8.3¥10-5 M) does not affect the adsorbed layers nor the interaction forces. However, when the SDS concentration is increased to 0.02 cmc (0.166 mM) the adsorbed layer expands dramatically due to adsorption of SDS to the polyelectrolyte chains. The sudden swelling suggests a cooperative adsorption of SDS to the preadsorbed polyelectrolyte layer, and that the critical aggregation concentration between the polyelectrolyte and SDS at the surface is about 0.02 cmc. The flocculation behaviour of the polyelectrolyte in solution upon addition of SDS was also examined. It was found that 0.16-0.32 mol SDS/mol charged segments on the polyelectrolyte is enough to make the solution slightly turbid.

    An investigation of dynamic surface tension, critical micelle concentration, and aggregation number of three nonionic surfactants using NMR, time-resolved fluorescence quenching, and maximum bubble pressure tensiometry2003Ingår i: Journal of Colloid and Interface Science, ISSN 0021-9797, E-ISSN 1095-7103, Vol. 262, s. 506-515Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Several physico-chemical properties have been determined for, N-dodecyllactobionamide (LABA), maltose 6'-O-dodecanoate (C12-maltose ester), and tetra(ethylene oxide) dodecyl amide (TEDAd). Attractive headgroup interactions due to the increase in the flexibility of the sugar headgroup reduces the area/molecule at the liquid-vapor interface both below and above the critical micelle concentration (cmc). The obtained cmc:s were 0.35 mM (LABA), 0.3 mM (C12-maltose ester) and 0.5 mM (TEDAd). The monomer diffusion coefficient decreased with the molecular weight, and increasing headgroup flexibility of the sugar headgroup, and values were in the range from 3.1¥10-10-3.6¥10-10 m2/s. The micelle diffusion coefficients (0.46¥10-10-0.68¥10-10 m2/s) indicated that the TEDAd micelles deviated most from spherical shape. The micelle aggregation numbers determined by TRFQ were estimated to be 120±10 (LABA), 90±10 (C12-maltose ester) and 130±10 (TEDAd). The dynamic surface tension measurements show that the adsorption of TEDAd to the liquid-vapor interface at short surface life-times is diffusion limited, whereas an adsorption barrier is present for the sugar surfactants. The analysis of the dynamic surface tension data above the cmc shows that the rate of demicellization is faster for TEDAd than for the two sugar-based surfactants.
