2. 1. Precalendering and its interaction with other unit processes in the manufacturing of woodfree paper and board

   Author : Olof Steffner; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; calendering; soft-nip calendering; wet press; compression; deformation; coating; water box;

   Abstract : ABSTRACTDuring calendering, which is done in order to improve its printing properties, the paper is compressed in one or more roll nips. Paper is a viscoelastic material and this will influence its performance during calendering. READ MORE

4. 2. Improved Oxidation Resistance and Reduced Cr Vaporization from Thin-Film Coated Solid Oxide Fuel Cell Interconnects

   Author : Hannes Falk Windisch; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 18O-Tracer exposure; Reactive Element; Coating; SOFC; Cr Vaporization; Interconnect; Corrosion;

   Abstract : High electrical efficiency, clean emissions, and the possibility to operate on a great variety of fuels, such as hydrogen, alcohols and hydrocarbons are some advantages of Solid Oxide Fuel Cell (SOFC) technology. Too short lifetimes and high production costs have, however, limited the commercialization of this technology. READ MORE

5. 3. Processing of berries – Effects on functionality, stability and bioactivity of anthocyanins

   Author : Gabriel Barbosa; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; berries; powder; hot air and microwave drying; osmotic dehydration; press cake; edible coating; anthocyanins; gastrointestinal in vitro digestion; polyphenols; pulsed electric field; oxidative stress; yeast;

   Abstract : Berries are rich natural sources of anthocyanins, water-soluble pigments in plants that have been linked to beneficial effects against chronic diseases, such as cardiovascular diseases, type 2 diabetes and neurodegenerative diseases. However, anthocyanins as well as other polyphenolic compounds are often sensitive to degradation during processing, storage and digestion. READ MORE

6. 4. Barrier Properties of greaseproof paper

   Author : Henrik Kjellgren; Gunnar Engström; Lennart Stolpe; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Greaseproof papers; Air permeance; Coatings; Chitosan; Oxygen Barrier properties; Chemical Engineering; Kemiteknik; Chemical engineering;

   Abstract : The barrier properties of greaseproof paper are achieved by extensive beating of the fibres. This treatment results in high costs for energy, both as beating energy and drying energy. A full-scale trial has been performed to investigate the role of the pulp with respect to energy demand and the barrier properties of the final papers. READ MORE

7. 5. Compression uniformity measurements on coated anduncoated paper surfaces

   Author : Isabel Endres; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

   Abstract : Paper is exposed to compressive stresses at several occasions in its production process and in subsequent printing operations. In the press section of a paper machine, the fibre web is mechanically dewatered by compression. READ MORE
