    Dissolution capacity of novel cellulose solvents based on triethyloctylammonium chloride2017In: Macromolecular Chemistry and Physics, ISSN 1022-1352, E-ISSN 1521-3935, Vol. 218, no 21, article id 1700208Article in journal (Refereed)
    Abstract [en]

    Dissolution of cellulose from various sources (microcrystalline cellulose and different dissolving grade pulp fibers) is investigated in solvent systems based on triethyl(n-octyl)ammonium chloride (N2228Cl). Clear cellulose solutions are obtained with N2228Cl in a variety of solvents, e.g., dimethyl sulfoxide, N,N-dimethylacetamide, and acetone. It is possible to prepare clear cellulose solutions from pulp fibers with concentrations up to 15 wt%. However, it is found that the cellulose is degraded, especially when neat (i.e., molten) N2228Cl is used as a solvent. The present work includes comprehensive rheological characterization of the cellulose solutions, both with shear and extensional rheology. In most cases, the viscosity values are low (complex viscosities below 100 Pa s for 5–10 wt% dissolved cellulose), and the solutions show more Newtonian than viscoelastic behavior.

    Surprising Insensitivity of Homogeneous Acetylation of Cellulose Dissolved in Triethyl(n-octyl)ammonium Chloride/Molecular Solvent on the Solvent Polarity2018In: Macromolecular materials and engineering (Print), ISSN 1438-7492, E-ISSN 1439-2054, Vol. 303, no 5Article in journal (Refereed)
    Abstract [en]

    The homogeneous acetylation of microcrystalline cellulose (MCC) by acetyl chloride and acetic anhydride in triethyl(n-octyl)ammonium chloride (N2228Cl)/molecular solvents (MSs) is investigated. The reaction with both acylating agents shows the expected increase of the degree of substitution (DS) on reaction temperature and time. Under comparable reaction conditions, however, DS is surprisingly little dependent on the MS employed, although the MSs differ in empirical polarity by 7 kcal mol−1 as calculated by use of solvatochromic probes. The empirical polarities of (MCC + N2228Cl + MS) differ only by 0.8 kcal mol−1. The formation a polar electrolyte sheath around cellulose chains presumably contributes to this “leveling-off” of the dependence DS on the polarity of the parent MS employed. N2228Cl recovery and recycling is feasible. © 2018 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim

    Defect Minimization in Prosthetic Ceramics2014In: Advanced Ceramics for Dentistry, Elsevier Inc. , 2014, p. 359-373Chapter in book (Refereed)
    Abstract [en]

    The mechanical reliability and aesthetic appearance of ceramic dental prostheses are strongly influenced by the presence of defects. When several processes are used during fabrication of ceramic dental prostheses, additional defects are unavoidably introduced in each process step; these are in addition to the ones that already exist in raw materials. To avoid the degeneration of material performance by the accumulated defect population, process optimization is needed to minimize the defects introduced. Standardized mechanical evaluations are usually performed on samples with carefully prepared surfaces in order to minimize the influence from the defects usually induced by fabrication processes. The results from such mechanical evaluation indicate the strength level that is achievable by the material with the given population of bulk defects. In order to avoid a reduction in the performance of the ceramic material by the additional defects normally induced by the fabrication process, it must be understood how these defects are introduced, and solutions must be found to reduce their size and frequency through modifications of the material and processes. The aim of this chapter is to elucidate the sources of defects that are common for ceramic dental prostheses and to determine how to minimize them. © 2014 Elsevier Inc. All rights reserved.

    Effects of granule density on strength and granule related defects in zirconia2012In: Journal of the European Ceramic Society, ISSN 0955-2219, E-ISSN 1873-619X, Vol. 32, no 11, p. 2653-2659Article in journal (Refereed)
    Abstract [en]

    A suspension of zirconia powder (TZ3YSE) with a solids loading of 50. vol% was prepared by ball milling. Binders were added and some of the suspension was diluted to 40, 30 and 20. vol% before freeze granulation was performed. A spray dried material (TZ3YSEB) was used as a reference. The pore size distribution of the different granules was evaluated and from the microstructure it was shown that inhomogeneities were present in both the freeze granulated as well as in the spray dried granules. In addition, the density, microstructure as well as the strength of sintered materials prepared from the granules were studied. The results showed that a high green density or sintered density was not sufficient in order to achieve a high strength material. It was further shown that the strength was significantly influenced by the granule density and not by the inhomogeneities found in the granules. © 2012.

    Novel reactive bicomponent fibres: Material in composite manufacturing2012In: Journal of Nanostructured Polymers and Nanocomposites, ISSN 17904439, Vol. 8, no 1, p. 11-majArticle in journal (Refereed)
    Abstract [en]

    The hypotheses that reactive uncured, thermoset bicomponent fibres can be prepared and mixed with reinforcing fibres and ultimately used in preparation of a composite was tested and is described. It is thought that such fibres have the two potential advantages: (1) to enable manufacturing with particle doped resins e.g. nanocomposites which add functionality to composites and (2) increased efficiency of structural composite manufacturing by increasing the level of automation. The structure of the thermoset fibres comprises of a sheath of thermoplastic and a core of uncured thermoset resin. Once manufactured, the fibres were wound with a reinforced fibre onto a plate, consolidated and cured. The resulting composite was examined and compared to other composites made with the same manufacturing method from commercially available materials. The results show that a laminate can be produced using these reactive bicomponent fibres. The resin system successfully impregnates the reinforcing carbon fibres and that the thermoplastic separates from the epoxy resin system during consolidation. In comparison to reference material, the bicomponent laminate shows promising characteristics. However, the processes developed are currently on a lab-scale and considerable improvement of various bicomponent fibre properties, such as the strength, are required before the technology can be used on a larger scale.

    Preparation of thermoset composites from natural fibres and acrylate modified soybean oil resins2009In: Journal of Applied Polymer Science, ISSN 0021-8995, E-ISSN 1097-4628, Vol. 114, no 4, p. 2502-2508Article in journal (Refereed)
    Abstract [en]

    Structural composites with a high content of renewable material were produced from natural fibres and an acrylated epoxidized soybean oil resin. Composites were prepared by spray impregnation followed by compression moulding at elevated temperature. The resulting composites had good mechanical properties in terms of tensile strength and flexural strength. Tensile testing as well as dynamical mechanical thermal analysis showed that increasing the fibre content, increased the mechanical properties. The resin can be reinforced with up to 70 wt % fibre without sacrifice in processability. The tensile modulus ranged between 5.8 and 9.7 GPa depending on the type of fibre mat. The study of the adhesion by low vacuum scanning electron microscopy shows that the fibres are well impregnated in the matrix. The aging properties were finally evaluated. This study shows that composites with a very high content of renewable constituents can be produced from soy bean oil resins and natural fibres. © 2009 Wiley Periodicals, Inc.

    Assessment of Novel Long-Lasting Ceria-Stabilized Zirconia-Based Ceramics with Different Surface Topographies as Implant Materials2017In: Advanced Functional Materials, ISSN 1616-301X, E-ISSN 1616-3028, Vol. 27, no 40, article id 1702512Article in journal (Refereed)
    Abstract [en]

    The development of long-lasting zirconia-based ceramics for implants, which are not prone to hydrothermal aging, is not satisfactorily solved. Therefore, this study is conceived as an overall evaluation screening of novel ceria-stabilized zirconia-alumina-aluminate composite ceramics (ZA8Sr8-Ce11) with different surface topographies for use in clinical applications. Ceria-stabilized zirconia is chosen as the matrix for the composite material, due to its lower susceptibility to aging than yttria-stabilized zirconia (3Y-TZP). This assessment is carried out on three preclinical investigation levels, indicating an overall biocompatibility of ceria-stabilized zirconia-based ceramics, both in vitro and in vivo. Long-term attachment and mineralized extracellular matrix (ECM) deposition of primary osteoblasts are the most distinct on porous ZA8Sr8-Ce11p surfaces, while ECM attachment on 3Y-TZP and ZA8Sr8-Ce11 with compact surface texture is poor. In this regard, the animal study confirms the porous ZA8Sr8-Ce11p to be the most favorable material, showing the highest bone-to-implant contact values and implant stability post implantation in comparison with control groups. Moreover, the microbiological evaluation reveals no favoritism of biofilm formation on the porous ZA8Sr8-Ce11p when compared to a smooth control surface. Hence, together with the in vitro in vivo assessment analogy, the promising clinical potential of this novel ZA8Sr8-Ce11 as an implant material is demonstrated.

    Cellular transcriptional response to zirconia-based implant materials2017In: Dental Materials, ISSN 0109-5641, E-ISSN 1879-0097, Vol. 33, no 2, p. 241-255Article in journal (Refereed)
    Abstract [en]

    Objective To adequately address clinically important issues such as osseointegration and soft tissue integration, we screened for the direct biological cell response by culturing human osteoblasts and gingival fibroblasts on novel zirconia-based dental implant biomaterials and subjecting them to transcriptional analysis. Methods Biomaterials used for osteoblasts involved micro-roughened surfaces made of a new type of ceria-stabilized zirconia composite with two different topographies, zirconium dioxide, and yttria-stabilized zirconia (control). For fibroblasts smooth ceria- and yttria-stabilized zirconia surface were used. The expression of 90 issue-relevant genes was determined on mRNA transcription level by real-time PCR Array technology after growth periods of 1 and 7 days. Results Generally, modulation of gene transcription exhibited a dual dependence, first by time and second by the biomaterial, whereas biomaterial-triggered changes were predominantly caused by the biomaterials’ chemistry rather than surface topography. Per se, modulated genes assigned to regenerative tissue processes such as fracture healing and wound healing and in detail included colony stimulating factors (CSF2 and CSF3), growth factors, which regulate bone matrix properties (e.g. BMP3 and TGFB1), osteogenic BMPs (BMP2/4/6/7) and transcription factors (RUNX2 and SP7), matrix collagens and osteocalcin, laminins as well as integrin ß1 and MMP-2. Significance With respect to the biomaterials under study, the screening showed that a new zirconia-based composite stabilized with ceria may be promising to provide clinically desired periodontal tissue integration. Moreover, by detecting biomarkers modulated in a time- and/or biomaterial-dependent manner, we identified candidate genes for the targeted analysis of cell-implant bioresponse during biomaterial research and development.

    COSIVU - Compact, smart and reliable drive unit for fully electric vehicles2016In: 2016 Pan Pacific Microelectronics Symposium, Pan Pacific 2016Article in journal (Refereed)
    Abstract [en]

    COSIVU is a three year collaborative research project that ended in September 2015 and which has been funded within the European Green Car Initiative (now the European Green Vehicle Initiative). COSIVU addresses one of the most critical technical parts in fully electrical vehicles (FEV) besides the energy storage system: the mechatronic drive-train unit. The COSIVU project has delivered a new system architecture for multiple wheel drive-trains by a smart, compact and durable single-wheel drive unit with integrated electric motor, full silicon carbide (SiC) power electronics (switches and diodes), a novel control and health monitoring module with wireless communication, and an advanced ultra-compact cooling solution. DfR utilizing FEM simulations ensures first time right solutions. This paper presents the main results including the architecture of the drive train solution as well as the modular design of the inverter based on Inverter Building Blocks, one per phase. Performance tests are presented here for the first time for both the heavy duty commercial vehicle solution performed in a test rig by Volvo, and the tests of the COSIVU solution adapted to a passenger car done by Elaphe.

    Smart access to small lot manufacturing for systems integration2018In: 2018 Pan Pacific Microelectronics Symposium, Pan Pacific 2018, 2018, p. 1-9Conference paper (Refereed)
    Abstract [en]

    The three year EU project SMARTER-SI that ends in January 2018 has tested a new concept for small lot manufacturing for SMEs which we call the Cooperative Foundry Model (CFM). During previous research, all RTOs have completed building blocks, i.e. components or parts of systems which are readily available and characterized by their high Technology Readiness Level (TRL). These building blocks are combined and integrated in so-called Application Experiments (AEs), thereby creating innovative Smart Systems that serve the SMEs' needs. Four pre defined AEs have been presented before [1] and in this paper, six additional AEs will be presented: i) a smart sensor for pneumatic combined clutch and brakes, ii) smart well plates for tissue engineering integrating continuous, non-invasive TEER iii) microclimate sensor for moisture applications, iv) LTCC-Si-Pressure Sensor, v) miniaturized capillary electrophoresis system for bio analysis, and vi) a MEMS sensor module for respiratory applications. Finally, a brief description of ongoing standardization efforts is presented.

    SMARTER-SI - Smart access to manufacturing for Systems Integration2017Conference paper (Refereed)
    Abstract [en]

    The three year EU project SMARTER-SI that started in February 2015 has developed and tested a new production platform for smart systems that offer SMEs and “mid-cap” companies help to manufacture small and medium volumes. The ultimate goal of this project is to test a new concept for small lot production, which we call the Cooperative Foundry Model (CFM). The CFM is tested by combining components or parts of systems (building blocks) already developed by the RTOs involved in the project in so-called Application Experiments (AEs), thereby creating innovative Smart Systems which serve SMEs' product needs. During the first two years, four predefined AEs have been developed that consist of i) a multi-parametric point of care testing (POCT) device, ii) a dew-point measurement system, iii) a CO2 measurement system, and iv) a portable device that can be used to screen water quality.

    Polymer Core-Polymer Shell Particle Formation Enabled by Ultralow Interfacial Tension Via Internal Phase Separation: Morphology Prediction Using the Van Oss Formalism2018In: Colloid and Interface Science Communications, ISSN 2215-0382, Vol. 25, p. 36-40Article in journal (Refereed)
    Abstract [en]

    The internal phase separation technique is a versatile method for liquid core-polymer shell formation, yet limited to very hydrophobic core materials and actives. The use of polymeric cores instead circumvents this restriction due to the absent mixing entropy for binary polymer mixtures which allows the polymeric core (and the active) to approach the polarity of the shell. Polystyrene core-shell and janus particles were formulated using polymethylmethacrylate, poly(lactic acid), poly(lactic acid-co-glycolic acid), poly(ε-caprolactone) or cellulose triacetate as shell-forming polymers. The morphology and the partitioning was experimentally determined by selectively staining the core and the shell with β-carotene and methylene blue respectively. In addition, the van Oss formalism was introduced to theoretically predict the thermodynamic equilibrium morphology. As elucidated using the theoretical predictions as well as experimental optical tensiometry, it was found that the driving force for core-shell morphology is, in contrast to liquid core-polymer shell particles, a low core-shell interfacial tension.

    Guided bone augmentation using ceramic space-maintaining devices: The impact of chemistry2015In: Clinical, Cosmetic and Investigational Dentistry, ISSN 11791357, Vol. 7, p. 45-53Article in journal (Refereed)
    Abstract [en]

    The purpose of the study was to evaluate histologically, whether vertical bone augmentation can be achieved using a hollow ceramic space maintaining device in a rabbit calvaria model. Furthermore, the chemistry of microporous hydroxyapatite and zirconia were tested to determine which of these two ceramics are most suitable for guided bone generation. 24 hollow domes in two different ceramic materials were placed subperiosteal on rabbit skull bone. The rabbits were sacrificed after 12 weeks and the histology results were analyzed regarding bone-to-material contact and volume of newly formed bone. The results suggest that the effect of the microporous structure of hydroxyapatite seems to facilitate for the bone cells to adhere to the material and that zirconia enhance a slightly larger volume of newly formed bone. In conclusion, the results of the current study demonstrated that ceramic space maintaining devices permits new bone formation and osteoconduction within the dome. © 2015 Anderud et al.

    The impact of surface roughness and permeability in hydroxyapatite bone regeneration membranes2015In: Clinical Oral Implants Research, ISSN 0905-7161, E-ISSN 1600-0501Article in journal (Refereed)
    Abstract [en]

    Background: One of the crucial aspects in guided bone regeneration is the space maintenance. This is normally created by a membrane, which should primarily be accepted by the surrounding tissues without causing any adverse reactions. The impact of surface topography, biological acceptance as well as permeability of these membranes has been carefully discussed in the literature. Purpose: The purpose of this study was to evaluate histologically the bone forming properties inside of hollow hydroxyapatite space-maintaining devices with different inner surfaces and different permeabilities in an animal calvaria model in vivo. Materials and methods: A total of 36 hollow domes with three different designs made of hydroxyapatite were surgically attached to the skulls of rabbits. Group 1 had a moderately rough inner surface. Group 2 had a smooth inner surface. Group 3 had the same properties as Group 1 but had macroscopic holes on the top. The domes were left to heal for 12 weeks and were then processed for undecalcified ground sectioning. Histological evaluations were performed using a light microscope and scanning electron microscopy. The bone-implant contact (BIC) percentage along the device was calculated. Results: The median percentage of BIC was higher for Group 1 compared with Group 2 (P = 0.004). Group 1 produced a larger median BIC compared with Group 3 (P < 0.0001). Conclusions: Within the limits of this preclinical study, these findings suggest that a moderately rough inner surface of a ceramic membrane along with a non-permeable device produces more bone than a smooth inner surface. © 2015 John Wiley & Sons A/S.

    Cirkulära möbelflöden: Hur nya affärsmodeller kan bidra till hållbar utveckling inom offentliga möbler2017Report (Other academic)
    Abstract [sv]

    Sverige har en stark möbelindustri och en stolt tradition av att tillverka tidlösa och högkvalitativa möbler, ofta av naturmaterial. 2016 producerade Sverige möbler för 22,8 miljarder SEK, varav kontorsmöbler stod för nästan en fjärdedel1. Det saknas idag statistik över vad som händer med dessa möbler när de inte längre används, men det står klart att många av dem slängs i förtid när verksamheter flyttar eller när deras behov ändras. Samtidigt syns en tydlig utveckling mot att kunder mer och mer efterfrågar återbrukade eller renoverade möbler som en del i sitt hållbarhetsarbete. Denna utveckling var startpunkten för projektet ”Affärsmodell-innovation för cirkulära möbelflöden”.

    Affärsmodellinnovation för cirkulära möbelflöden är ett Vinnovafinansierat projekt som under åren 2015-2017 arbetat med att utveckla och testa koncept för cirkulära affärsmodeller för i första hand offentliga möbler. I projektet har tjugo aktörer från hela värdekedjan, från underleverantörer, möbelproducenter, återförsäljare och användare till forskare och branschorgan, samarbetat kring affärsutveckling, kundincitament, produktdesign, logistik, hållbarhets- och certifieringsfrågor.

    Den här skriften belyser hur nya affärsmodeller för mer cirkulära möbelflöden kan bidra till en mer hållbar utveckling och ger smakprov på slutsatser från projektet. Skriften riktar sig framför allt till producenter och återförsäljare av möbler för offentliga miljöer, men även kunder och inköpare tror vi kan ha stor nytta av skriften. Vi hoppas att den även kan fungera som inspiration för andra industrier och branscher som funderar på en övergång till mer cirkulära affärsekosystem.

    Improved yield of carbon fibres from cellulose and kraft lignin2018In: Holzforschung, ISSN 0018-3830, E-ISSN 1437-434XArticle in journal (Refereed)
    Abstract [en]

    To meet the demand for carbon-fibre-reinforced composites in lightweight applications, cost-efficient processing and new raw materials are sought for. Cellulose and kraft lignin are each interesting renewables for this purpose due to their high availability. The molecular order of cellulose is an excellent property, as is the high carbon content of lignin. By co-processing cellulose and lignin, the advantages of these macromolecules are synergistic for producing carbon fibre (CF) of commercial grade in high yields. CFs were prepared from precursor fibres (PFs) made from 70:30 blends of softwood kraft lignin (SW-KL) and cellulose by dry-jet wet spinning with the ionic liquid (IL) 1-ethyl-3-methylimidazolium acetate ([EMIm][OAc]) as a solvent. In focus was the impact of the molecular mass of lignin and the type of cellulose source on the CF yield and properties, while membrane-filtrated kraft lignin and cellulose from dissolving kraft pulp and fully bleached paper-grade SW-KP (kraft pulp) served as sources. Under the investigated conditions, the yield increased from around 22% for CF from neat cellulose to about 40% in the presence of lignin, irrespective of the type of SW-KL. The yield increment was also higher relative to the theoretical one for CF made from blends (69%) compared to those made from neat celluloses (48-51%). No difference in the mechanical properties of the produced CF was observed.

    Understanding the Inhibiting Effect of Small-Molecule Hydrogen Bond Donors on the Solubility of Cellulose in Tetrabutylammonium Acetate/DMSO2017In: Journal of Physical Chemistry B, ISSN 1520-6106, E-ISSN 1520-5207, Vol. 121, no 50, p. 11241-11248Article in journal (Refereed)
    Abstract [en]

    Certain ionic liquids are powerful cellulose solvents, but tend to be less effective when small-molecule hydrogen bond donors are present. This is generally attributed to competition with cellulose for hydrogen bonding opportunities to the anion of the ionic liquid. We show that the solubility of cellulose in dimethyl sulfoxide solutions of tetrabutylammonium acetate is less strongly affected by water than by ethanol on a molar basis, contrary to what can be expected based on hydrogen bond stoichiometry. Molecular dynamics simulations indicate that the higher tolerance to water is due to water-cellulose interactions that improves solvation of cellulose and, thereby, marginally favors dissolution. Through Kirkwood-Buff theory we show that water, but not ethanol, improves the solvent quality of DMSO and partly compensates for the loss of acetate-cellulose hydrogen bonds.

    Machining Equipment Life Cycle Costing Model with Dynamic Maintenance Cost2016In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 48, p. 102-107Article in journal (Refereed)
    Abstract [en]

    This paper presents how a Life cycle cost or Total cost of ownership analysis has been performed on machining equipment in a Swedish company. Life cycle cost models used in case studies are compared to an empirical model, used at the company, where dynamic energy, fluid, and maintenance cost are included. Linear and variable factors in the models are analyzed and discussed regarding data availability and estimation, especially with emphasis on maintenance. The life cycle cost aspect of the equipment give guidelines to consider operation, maintenance, tools, energy, and fluid cost in addition to acquisition cost, when designing/specifying the equipment.

    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.

    New ways of organizing product introductions2012In: Work, 2012, Vol. 41, no SUPPL.1, p. 4856-4861Conference paper (Refereed)
    Abstract [en]

    The aim of this paper is to describe and reflect on an interactive research approach used to address the challenges on how to improve product introductions, the part of the product realization process associated with the transfer of a product from product development to serial production. In the interactive research approach, research results as well as improvement of practice are given equal importance. The collaboration between researchers and practitioners therefore addresses both the focus and the process of the change. The approach includes four main iterative steps: 1) mapping/diagnosis, 2) feedback of results, 3) participation in development activities, and 4) follow-up/evaluation. The paper reports findings from interactive research in one company within office product industry and one company group, consisting of three company units within the engine industry. Preliminary findings indicate that the participating companies afterwards work in a more structured way with product introductions and that the employees have gained deeper knowledge about product introductions as well as experienced the advantages of working across functional boundaries. Furthermore, the interactive research approach is suitable to run projects from an ergonomics perspective as it focuses on developing both practice and theory, it is human-centered, and it emphasizes broad participation from practitioners. © 2012 - IOS Press and the authors.

    Boundary crossing in product introductions considering humans, technology and organization2014In: Proceedings of ODAM NES 2014 / [ed] O. Broberg, N. Fallentin, P. Hasle, P.L. Jensen, A. Kabel, M.E. Larsen, T. Weller, 2014, p. 349-354Conference paper (Refereed)
    Abstract [en]

    The objective of the paper is to analyze how a product introduction involving Swedish-Chinese collaboration was influenced by human, technological and organizational aspects. The study showed that technical challenges concerned the infrastructure for communication and quality issues; organizational challenges concerned the new project model and updating drawing versions; and human related challenges included cultural differences and communication. The product introduction was highly challenging by crossing earlier boundaries in the human, technical, and organizational subsystems. Strong work demands were placed on the individuals while offering great opportunities for individual learning. Concurrent development of a new project model resulted in organizational learning.

    Det värdefulla engagemanget: En guide för Lean och för andra strategier för utveckling2011Book (Other academic)
    Abstract [sv]

    En organisation där alla agerar på eget initiativ för det gemensamma bästa, där alla är beredda att hugga i när det behövs, där alla samspelar för att nå resultat och där alla bidrar till att utveckla organisationen-visst är detta en dröm?Alla vill att medarbetarna och kollegorna ska engagera sig. Men varför skulle de? Har företaget gjort sig förtjänt av att någon gör mer än hon måste?I de allra flesta organisationer underskattas gravt den omsorg som behövs för att medarbetarna ska finna det mödan värt att engagera sig. Det krävs ett klokt och långsiktigt arbete från ledning och chefer för att bygga en företagskultur av förtroende och samverkan, men om det lyckas finns oanade vinster att hämta.Den nya boken, Det värdefulla engagemanget-En guide för Lean och andra strategier för utveckling, vill stimulera till en reflektion kring hur organisationen och ledningen påverkar medarbetarnas engagemang. Boken följer upp vår tidigare bok Lean i ledningen-Utmana hela organisationen, som blivit mycket uppskattad, men Det värdefulla engagemanget är till nytta oberoende av eventuella Leansatsningar.Tio teman behandlas: En färdriktning • En kultur av tillit • Aktiv ledning • Långsiktighet • Utrymme för individen • Lagarbete • Inflytande • Utmaning • Lärande • Del av vinstenDe kunskaper och erfarenheter som lett fram till boken har sin grund i många års uppdrag och forskningsprojekt inom industrin och även i tjänsteföretag. Boken bygger till stor del på en doktorsavhandling,Engagemang efterfrågas – Hur tre tillverkande företag söker medverkan från sina medarbetare när de inför Lean, men är förenklad och omskriven för att direkt kunna tillämpas.

    Factors affecting the accuracy of flow stress determined by the bulge test2011In: Special Edition: 10th International Conference on Technology of Plasticity, ICTP 2011, 2011, p. 726-731Conference paper (Refereed)
    Abstract [en]

    The determination of the flow stress curve at room temperature, using the bulge test under biaxial deformation conditions, has been extensively studied. However, two Issues still deserve close examination: (1) validity of assuming a spherical bulge shape and (2) the effects of yield criterion and/or normal anisotropy. In this paper, we present experimental measurements to validate spherical assumption, as well as a methodology to calculate flow stress curves, all the way up to the failure point, that are free from the effects of anisotropy. Experimental studies were conducted on draw quality steel (DQS) and several grades of Dual Phase (DP) Advanced High Strength Steels (AHSS). © 2011 Wiley-VCH Verlag GmbH & Co. KGaA. Weinheim.

    Implementation challenges affecting the environmental improvement performance in pharmaceutical production: Results of a green kaizen pilot2018In: IFIP Advances in Information and Communication Technology, ISSN 1868-4238, Vol. 535, p. 58-66Article in journal (Refereed)
    Abstract [en]

    This paper reports on working findings in an action research-based project, implementing a green kaizen pilot in a European pharmaceutical manufacturing company. The aim of the study is to investigate how continuous improvement initiatives with focus on environment originally developed for the automotive manufacturing industry could apply to the pharmaceutical industry. It also aspires to understand the enabling and hindering issues are for such implementation. There are considerable similarities of implementing lean in general in the two sectors, however, some key differences and challenges were apparent when implementing this specific green kaizen method called Green Performance Map. An implication for pharma practitioners implementing the green kaizen method concerns how to improve working procedures and production equipment to become more environmentally friendly amid high regulatory demands on process quality. Implementation challenges are discussed in terms of fidelity, locus and extensiveness of lean practices implementation. © 2018, IFIP International Federation for Information Processing.

    Nano-fiber scaffold electrodes based on PEDOT for cell stimulation2009In: Sensors and actuators. B, Chemical, ISSN 0925-4005, E-ISSN 1873-3077, Vol. 142, no 2, p. 451-456Article in journal (Refereed)
    Abstract [en]

    Electronically conductive and electrochemically active 3D-scaffolds based on electrospun poly(ethylene terephthalate) (PET) nano-fibers are reported. Vapour phase polymerization was employed to achieve an uniform and conformal coating of poly(3,4-ethylenedioxythiophene) doped with tosylate (PEDOT:tosylate) on the nano-fibers. The PEDOT coatings had a large impact on the wettability, turning the hydrophobic PET fibers super-hydrophilic. SH-SY5Y neuroblastoma cells were grown on the PEDOT coated fibers. The SH-SY5Y cells adhered well and showed healthy morphology. These electrically active scaffolds were used to induce Ca2+ signalling in SH-SY5Y neuroblastoma cells. PEDOT:tosylate coated nano-fibers represent a class of 3D host environments that combines excellent adhesion and proliferation for neuronal cells with the possibility to regulate their signalling. © 2009 Elsevier B.V.
