2. 1. Protein-based Packaging Films, Sheets and Composites: Process Development and Functional Properties

   Author : Sung-Woo Cho; Mikael Hedenqvist; Amar K. Mohanty; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; wheat gluten; solution casting; compression molding; extrusion; injection molding; aging; migration; opacity; heat sealability; hemp fiber; laminate; polylactic acid; clay; nanocomposites.; Other chemical engineering; Övrig kemiteknik;

   Abstract : The depletion of the petroleum resources and a number of environmental concerns led to considerable research efforts in the field of biodegradable materials over the last few decades. Of the diverse range of biopolymers, wheat gluten (WG) stands out as an alternative to synthetic plastics in packaging applications due to its attractive combination of flexibility and strength, high gas barrier properties under low humidity conditions and renewability.

4. 2. Synthesis of Organic Chromophores for Dye Sensitized Solar Cells

   Author : Daniel Hagberg; Licheng Sun; Elena Galoppini; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acceptor; chromophore; donor; dye sensitized solar cells; HOMO and LUMO energy level tuning; linker; organic dye.; Chemical engineering; Kemiteknik;

   Abstract :   This thesis deals with development and synthesis of organic chromophores for dye sensitized solar cells. The chromophores are divided into three components; donor, linker and acceptor. The development of efficient organic chromophores for dye sensitized solar cells starts off with one new organic chromophore, D5. READ MORE

5. 3. Molecular Electronics - Modeling, Devices and Architecture

   Author : Jonas Sköldberg; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Molecular electronics; memristor; self-assembly; threshold logic; switching networks; hybrid devices; NDR; hysteresis; reconfigurable logic; nanocell;

   Abstract : Molecular electronics is an area of micro/nanoelectronics with a number of farreaching goals and challenges: denser implementation of electronic memory and logic, less expensive manufacturing, smaller or more sensitive measurement devices, selfassembly of devices and systems and, last but not least, exploring new science and applications.In recent years, molecular electronics has expanded into a broader field of molecular-scale electronics, partly because molecular components have to be defined in solid-state contexts via lithography and self-assembly, and effectively become hybrid devices with new and interesting properties.

6. 4. Effects of plasticizing and crosslinking on coatings based on blends of starch-PVOH and starch-lignin

   Author : Asif Javed; Henrik Ullsten; Peter Rättö; Lars Järnström; Douglas Bousfield; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Citric acid; Glycerol; Polyethylene glycol; Barrier coatings; Starch; Lignin; Mechanical properties; Poly vinyl alcohol ; Creasing; Adhesion; Cross-linking; Extrusion coating; Chemical Engineering; Kemiteknik;

   Abstract : A barrier material is usually needed on a fiber-based food package to protect the packed food from gases and moisture and thus maintain its quality. Barrier materials presently used in food packaging applications are mostly petroleum-based polymers. READ MORE

7. 5. Effects of plasticizing and crosslinking on the mechanical and barrier properties of coatings based on blends of starch and poly(vinyl alcohol)

   Author : Asif Javed; Lars Järnström; Henrik Ullsten; Peter Rättö; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Citric acid; Glycerol; Polyethylene glycol; Barrier properties; Starch; Mechanical properties; Polyvinyl alcohol; Adhesion; Cross linking; Extrusion coating; Chemical Engineering; Kemiteknik;

   Abstract : In the last decades, intensive research has been carried out in order to replace oil-based polymers with bio-based polymers due to growing environmental concerns. So far, most of the barrier materials used in food packaging are petroleum-based materials. READ MORE
