  1. 31. Processing and Properties of Expanded Starch Materials

    Författare :Mia Sjöqvist; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; amylopectin; extrusion; starch; porosity; foams; moisture content; amylose; microwave treatment; absorption;

    Sammanfattning : The need to strive towards a more sustainable development of the society is becoming increasingly urgent. As the population of the world is growing so is society´s impact on the environment. This is causing environmental problems with growing amounts of waste. LÄS MER

  3. 32. Two-dimensional Nanocomposites Based on Cellulose Nanofibrils and Graphene Oxide

    Författare :Hanieh Mianehrow; Lars Berglund; Aji Mathew; KTH; []
    Nyckelord :Cellulose nanofibrils; graphene oxide; orientation; reinforcement; oxygen barrier; bio-nanocomposite; moisture; molecular adhesion; interfacial shear strength.; Nanocellulosa; grafenoxid; orientering; förstärkning; syrebarriär; bionanokomposit; fukt; molekylär adhesion; skjuvhållfasthet hos gränsytan.; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Two-dimensional (2D) nanocomposites based on cellulose nanofibrils (CNF) and 2D nanomaterials are of interest as sustainable materials combining functional and structural properties. To achieve reinforcement effects from 2D nanomaterials, their orientation and dispersion state in the CNF matrix are important. LÄS MER

  4. 33. Retarded sorption in wood : experimental study, analyses and modeling

    Författare :Håkan Håkansson; Institutionen för arkitektur och byggd miljö; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building construction; transient; non-linear model; swelling-shrinkage; latent heat effect; history-dependent sorption; anomalous sorption; non-Fickian; retarded sorption; measurements; moisture; wood; Byggnadsteknik;

    Sammanfattning : Models of moisture flow processes in wood are normally based on a Fickian approach. In many instances, there are considerable discrepancies between modelling and experimental results. It is shown in this thesis that a major cause for these discrepancies is a so-called retarded sorption which is not accounted for in conventional theories. LÄS MER

  5. 34. Microwave Measurement Systems for In-line 3D Monitoring of Pharmaceutical Processes

    Författare :Livia Cerullo; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; permittivity; moisture content; microcrystalline cellulose; Pharmaceutical processes; dispersive media; finite element method; microwave measurements;

    Sammanfattning : The monitoring and understanding of pharmaceutical processes are important in order to achieve high-quality products at a low-production cost. The presence of water, e.g. as moisture content in the solid-state pharmaceutical material, is ofparticular interest and importance. LÄS MER

  7. 35. Diagnostics of Oil-Impregnated Paper Insulation Systems by Utilizing Lightning and Switching Transients

    Författare :Roya Nikjoo; Hans Edin; Christer Törnkvist; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Capacitance; Dielectric Response; Loss tangent; Moisture content; Oil - impregnated paper; Temperature; Transformer Bushing; Transients;

    Sammanfattning : Development of the power gridtowards a more reliable and smarter system requires frequent on-line monitoring of the power components. Power transformers and their bushings are particularly important components in a power transmission system and their insulation degradation may lead to catastrophic failures. LÄS MER
