    Adsorption structures in food emulsions1992In: Emulsions: A fundamental and practical approach / [ed] Sjöblom, J., Kluwer Academic Publishers, 1992, p. 51-60Chapter in book (Refereed)
    Abstract [en]

    Food emulsions in particular, but also most other technical emulsions, are complex mixtures. When surface active components adsorb from a solution of several different surface active molecules, the formed adsorbed layer can roughly be classified in three different structures, i) A monolayer containing one predominant molecule, ii) The formation of one adsorbed monolayer containing a mixture of molecules, iii)Adsorption in layers. A model of an ice cream emulsion is an example in which a layered surface structure is formed. Four different methods were applied to investigate the surface: measurements of the interfacial tension, flocculation rate measurements, electrophoretic mobility measurements and TIRF (Total Internal Reflection Fluorescence). The conclusion we made from this investigation was that the adsorption from solutions with several surface active components might lead to the formation of complex layered structures.

    Abstract [en]

    Introduction: The use of waterborne alkyds as binders in coatings is not new, their history going some 30 years back in time. Mostly, this has been in the form of water soluble alkyds, with high acid numbers that provide the water solubility of the resins after neutralization with amines. Such alkyds are mostly used in industrial coatings. Emulsified water insoluble alkyds have so far found most use in the field of decorative and protective coatings, although their use is still limited. A major factor limiting the use of alkyd emulsions is their low rate of oxidative drying, together with some remaining problems concerning colloidal stability of the emulsions. Several factors are believed to contribute to the reduced drying properties of alkyd emulsions as for example interaction between the drier and other paint components and solubility properties of the drier. A water borne paint is a complex system that besides the alkyd droplets in water also contains pigments, dispersants (to stabilize the pigments), surfactants (stabilizing the alkyd droplets), thickeners and several other additives, see Figure 1. The impaired film properties may at least partly be caused by the surfactant which will remain in the paint film and act as a plasticizer. For the segment decorative and protective coatings in Western Europe the market volumes are as follows (solid binder): Solventbased, low solids: 400 ktonne/annum Waterbased, polymer dispersion: 375 ktonne/annllrn Solventbased, high solids: 20 ktonne/annum Alkyd emulsion based: 15 ktonne/annum In most cases the alkyd emulsion is used as co-binder, especially in (hiding) stains and primers for exterior use. In these segments alkyds in white spirit are however still the binder of choice. In the case of alkyd resins for the decorative field, the environmentally friendly possibilities are either as high solids systems or as waterborne emulsions. With the present state of technology, it is very unlikely that alkyd emulsions can match the performance of the present solvent based siliconized alkyds and other extreme outdoor durable systems. Because of their more conventional permeability behaviour and the higher applied layer thickness, high solids seem more suitable for this purpose. Going to the lower end of the market, high solids systems can be applied in almost every segment, the only limitation being their price. For the lowest segments (primers and stains) their application will be limited.It is in these segments that acrylic dispersions have acquired a good reputation both their performance and price have been accepted. In the middle section, ranging from normal outdoor durable alkyds to the better performance stains, alkyd emulsions can be positioned. Their versatility and excellent environmental score (no volatile organic components are necessary) make them exceptionally suitable for this. In many outdoor applications alkyd emulsions will be compared with acrylate dispersions. Typical advantages of acrylate dispersions are their low particle size, quick drying, and good outdoor durability. The last two of these advantages can also be regarded as a disadvantage, since the drying often is considered to be too quick when only small amounts (under 5 %) of coalescing agent are used. The nomenclature then changes from "quick drying" to "short open times". The advantage of good outdoor durability is a.o. based on a good hydrolysis resistance, meaning that although it may take long, once a coating based on acrylic dispersion has deteriorated, the remainders cannot be removed by the usual alkaline paint stripper or heat gun (the dispersions are thermoplastic). Instead flakes of coating will come loose and remain in the environment. The main disadvantage of acrylate dispersions however, the seriousness of which is once again depending upon the application area, is that there always has to be some compromise between film formation (low MFI ) and good blocking properties (high Tg). Since in alkyd emulsions not all chemistry is "finished" when the film is applied, these emulsions can be expected to outperform the thermoplastic dispersions when it comes to properties that are related with film formation from a low Tg material, such as penetration (one of the factors controlling adhesion) and gloss, combined with good dirt pick-up resistance. Whereas the contents of a particle in a polymer dispersion is a true polymer (MW = 100.000 to 1.000.000), in an alkyd emulsion particle we find an oligomer, with a molecular weight ranging from 2000 to 8000. To make a real polymer out of it, the help of cobalt and atmospheric oxygen is required , just as is the case with a conventional alkyd. The fact that molecular buildup still has to take place also means that "derailments" of the crosslinking process will also take place. This means that a film cast from an alkyd emulsion will still exhibit the usual alkyd yellowing and slightly pungent smell. These are caused by decadienal-like structures and hexaldehyde, respectively, resulting from decomposition of the initial hydroperoxide and subsequent beta scission. Always compare an alkyd emulsion with an alkyd and not with a polvmer dispersion in this respect. The aspects where alkyd emulsions differ mostly form solvent-borne alkyd systems are: a) that they are formulated together with water, inducing a risk of hydrolysis upon storage, b) the disperse state of the alkyd, necessitating a high degree of colloidal stability and c) the peculiarities shown in the drying properties of alkyd emulsions. These aspects will be dealt with in the following paragraphs.

    Abstract [en]

    Polar lipids have an important role as emulsifiers and stability controlling agents in the food industry. The principal effects of the emulsifiers have been found to depend on the situation in which they are applied. They may act as stabilising additives, creating repulsive interactions between droplets. They may act as emulsifying agents, or they may destabilise emulsions by reducing protein adsorption at the oil/water interface. They may also destabilise emulsions by increasing wettability of fat crystals. Furthermore, they may form micellar or liposomal aggregates in the dispersion, influencing interactions and aggregation.

    Structural forces reflecting polyelectrolyte organization from bulk solutions and within surface complexes2002In: Advances in Colloid and Interface Science, ISSN 0001-8686, E-ISSN 1873-3727, Vol. 96, p. 1-20Article in journal (Refereed)
    Abstract [en]

    The interactions between two macroscopic surfaces approaching one another underlies many of the phenomena observed in Colloid and Interface science. In Russia this gave rise to the branch of colloid science now referred to as Surface Forces. Important discoveries, such as the molecular organization of solvent molecules at an interface, have been unveiled by surface force measurements. More recently, forces and structures at macromolecular length scales have been uncovered. In particular, oscillatory force profiles have been detected from aqueous solutions containing polyelectrolytes. The force¯structure relationship can reflect organization in the bulk solution or the internal structure of the adsorbed layer. Using a range of surface force techniques, combined with X-ray and neutron scattering results, we review the main features of these fascinating systems and provide an overview of how they relate to other systems such as micellar solutions, polymer¯surfactant complexes and simple solvents.

    Disjoining pressure measurements for foam films stabilized by a nonionic sugar-based surfactant1996In: Langmuir, ISSN 0743-7463, E-ISSN 1520-5827, Vol. 12, p. 1336-1342Article in journal (Refereed)
    Abstract [en]

    Disjoining pressure isotherms for foam films made from a nonionic surfactant, octyl b-glucoside, are measured at different surfactant concentrations, ionic strengths and solution pH values. Below the cmc an electrostatic double-layer repulsion is present and dominates the long-range interaction. The decay length of the forces agrees with the expected Debye length and the measured long-range interactions are consistent with solutions to the non-linear Poisson-Boltzmann equation using constant charge conditions. The deduced surface charge densities increase with pH and ionic strength but decrease with increasing surfactant concentration. At, or just above, the cmc, surfactant covers the interface and suppresses the charge sufficiently to induce a transition from a common black film to a Newton black film. Ultimately, the film stability is determined by both surface forces and elasticity. Combining both, via an overall film tension, leads to a general expression for the film elasticity.

    Browsing the Real World using Organic Electronics, Si-Chips, and a Human Touch2016In: Advanced Materials, ISSN 0935-9648, E-ISSN 1521-4095, Vol. 28, no 10, p. 1911-1916Article in journal (Refereed)
    Abstract [en]

    Two different e-labels were developed to explore the feasibility and to identify scientifi c and engineering challenges of the Real-World-Web platform. First was a printed biosensor e-label, comprising Si-chips with an array of different printegrated devices, and second, an e-label to explore the feasibility of transferring data, through the human body, between a mobile device and different distributed e-labels, adhered onto the body or onto dedicated devices and surfaces of one's ambience. The silicon chips utilized in e-labels, include analogue and digital circuitry to receive and handle sensory input, to perform signal processing, and to transmit information to antennas and displays. When used, the e-label is turned on, and a sample is then added onto the sensor area. The display provides simple instructions and updated information to the user. All data handling, electrical probing, and analysis of the sensor is performed by the Si-chips, and the sensing data is finally shown in the printed display. The second e-label exemplifies an ID-tag for body area networks (BAN) communication applications, which, in part, is manufactured and integrated in the same way as the first e-label, but with another choice of Si-chips and capacitive antennas.

    Estimating winter survival of winter wheat by simulations of plant frost tolerance2018In: Journal of Agronomy and Crop Science, ISSN 0931-2250, E-ISSN 1439-037X, Vol. 204, no 1, p. 62-73Article in journal (Refereed)
    Abstract [en]

    Based on soil temperature, snow depth and the grown cultivar's maximum attainable level of frost tolerance (LT50c), the FROSTOL model simulates development of frost tolerance (LT50) and winter damage, thereby enabling risk calculations for winter wheat survival. To explore the accuracy of this model, four winter wheat cultivars were sown in a field experiment in Uppsala, Sweden in 2013 and 2014. The LT50 was determined by tests of frost tolerance in November, and the cultivars’ LT50c was estimated. Further, recorded winter survival from 20 winter wheat field variety trials in Sweden and Norway was collected from two winter seasons with substantial winter damages. FROSTOL simulations were run for selected cultivars at each location. According to percentage of winter damage, the cultivar survival was classified as “survived,” “intermediate” or “killed.” Mean correspondence between recorded and simulated class of winter survival was 75% and 37% for the locations in Sweden and Norway, respectively. Stress factors that were not accounted for in FROSTOL might explain the poorer accuracy at the Norwegian locations. The accuracy was poorest for cultivars with intermediate LT50c levels. When low temperature was the main cause of damage, as at the Swedish locations, the model accuracy was satisfying.

    Fibrinogen Adsorption and Conformational Change on Model Polymers: Novel Aspects of Mutual Molecular Rearrangement2009In: Langmuir, ISSN 0743-7463, E-ISSN 1520-5827, Vol. 25, no 10, p. 5602-5608Article in journal (Refereed)
    Abstract [en]

    By combining quartz crystal microbalance with dissipation monitoring (QCM-D) and surface plasmon resonance (SPR), the organic mass, water content, and corresponding protein film structure of fibrinogen adsorbed to acrylic polymeric substrates with varying polymer chain flexibility was investigated. Albumin and immunoglobulin G were included as reference proteins. For fibrinogen, the QCM-D model resulted in decreased adsorbed mass with increased polymer chain flexibility. This stands in contrast to the SPR model, in which the adsorbed mass increased with increased polymer chain flexibility. As the QCM-D model includes the hydrodynamically coupled water, we propose that on the nonflexible polymer significant protein conformational change with water incorporation in the protein film takes place. Fibrinogen maintained a more native conformation on the flexible polymer, probably due to polymer chain rearrangement rather than protein conformational change. In comparison with immunoglobulin G and albumin, polymer chain flexibility had only minor impact on adsorbed mass and protein structure. Understanding the adsorption and corresponding conformational change of a protein together with the mutual rearrangement of the polymer chain upon adsorption not only has implications in biomaterial science but could also increase the efficacy of molecular imprinted polymers (MIPs).

    Experiences from feeding and co-firing of lignin powder in a lime kiln2010In: International Chemical Recovery Conference, 2010, Vol. 1, p. 175-187Conference paper (Refereed)
    Abstract [en]

    A significant part of the fossil fuel oil consumption at a pulp mill today is related to combustion in the lime kiln. Therefore, replacing fuel oil with lignin in this application has been one of the most important issues in the FRAM2 (Future Resource-Adapted Mill) research program coordinated by Innventia (formerly STFl-Packforsk) and funded by Sodra and other partners. A full-scale trial to fire lignin powder in a lime kiln was carried out at the Sodra Cell Monsteras mill, as part of the research program. In total 37 tonnes of lignin was co-fired with fuel oil. For part of the trial the kiln was operated on 100 % lignin. The experiences from the trial imply that it is possible to achieve stable and continuous operation of a lime kiln when lignin is used as the main fuel. The temperature levels in the kiln are of the same order of magnitude as when firing fuel oil or wood powder. Sulfur capture by the lime is very efficient, but there is a threshold above which S02 emissions increase rapidly. In the trial this step change occurred when going from 90 % to 100 % lignin firing. Based on the trial results, it is possible to produce lime with consistent quality when firing lignin, and the temperature reached in the burner zone is sufficient for proper sintering of the lime nodules. White liquor can be produced from the lime with the same causticizing efficiency and at the same rate as during normal operation. The mill operators also commented that it was easier to control the performance of the kiln when co-firing lignin and oil compared to the normal operation with co-firing of bark and oil.

    Pilot-scale combustion studies with kraft lignin as a solid biofuel2008In: Engineering, Pulping and Environmental Conference 2008, TAPPI Press, 2008, Vol. 4, p. 2571-2580Conference paper (Refereed)
    Abstract [en]

    Processing of kraft lignin precipitated from black liquor to produce a solid biofuel with high energy density and low ash content has been developed in research programs by STFI-Packforsk and partners. In preparation for full-scale combustion trials, tests were carried out on pilot scale in a 150 kW powder burner and in a 12 MWfluidized bed (CFB) boiler. Lignin powder could be fired in a powder burner with good combustion performance after some trimming of the airflows to reduce swirl. Lignin dried to 10 % moisture content was easy to feed smoothly and had less bridging tendencies in the feeding system than wood/bark powder. In the CFB boiler lignin was easily handled and co-fired together with bark. Although the filter cake was broken into smaller pieces and fines the combustion was not disturbed. When co-firing lignin with bark, the sulfur emission increased compared to bark firing only, but most of the sulfur was captured by calcium in the bark ash. Conventional sulfur capture with addition of limestone to the bed was also demonstrated. The sulfur content in the lignin had a significantly positive effect on reducing the alkali chloride content in the deposits, thus reducing the high temperature corrosion risk.

    Pilot-scale combustion studies with kraft lignin in a powder burner and a CFB boiler2010In: TAPPI Journal, ISSN 0734-1415, Vol. 9, no 6, p. 24-30Article in journal (Refereed)
    Abstract [en]

    Processes have been developed to produce a solid biofuel with high energy density and low ash content from kraft lignin precipitated from black liquor. Pilot-scale tests of the lignin biofuel were carried out with a 150 kW powder burner and a 12 MW circulating fluidized bed (CFB) boiler. Lignin powder could be fired in a powder burner with good combustion performance after some trimming of the air flows to reduce swirl. Lignin dried to 10% moisture content was easy to feed smoothly and had less bridging tendencies in the feeding system than did wood/ bark powder. In the CFB boiler, lignin was easily handled and cofired together with bark. Although the filter cake was broken into smaller pieces and fines, the combustion was not disturbed. When cof ¡ring lignin with bark, the sulfur emission increased compared with bark firing only, but most of the sulfur was captured by calcium in the bark ash. Conventional sulfur capture also occurred with addition of limestone to the bed. The sulfur content in the lignin had a significantly positive effect on reducing the alkali chloride content in the deposits, thus reducing the high temperature corrosion risk. Application: This research is of interest for pulp and paper and energy and utilities companies that want to understand how kraft lignin can be used to replace fuel oil or coal in many combustion applications.

    A method for visualization of surface texture anisotropy in different scales of observation2011In: Scanning, ISSN 0161-0457, E-ISSN 1932-8745, Vol. 33, no 5, p. 325-331Article in journal (Refereed)
    Abstract [en]

    Anisotropy of functional surfaces can in many practical cases significantly influence the surface function. Tribological contacts in sheet forming and engine applications are good examples. This article introduces and exemplifies a method for visualization of anisotropy. In a single graph, surface texture properties related to the anisotropy as a function of scale are plotted. The anisotropy graph can be used to explain anisotropy properties of a studied surface such as texture direction and texture strength at different scales of observation. Examples of milled steel surfaces and a textured steel sheet surface are presented to support the proposed methodology. Different aspects of the studied surfaces could clearly be seen at different scales. Future steps to improve filtering techniques and an introduction of length-scale analysis are discussed.
