2. 1. Paper-based Supercapacitors

   Author : Britta Andres; Håkan Olin; Mats Sandberg; Mittuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; graphene; graphite; paper; nano fibrillated cellulose; supercapacitor; electric double-layer capacitor; energy storage; roll-to-roll; coating; kinetic energy recovery;

   Abstract : The growing market of mobile electronic devices, renewable off-grid energy sources and electric vehicles requires high-performance energy storage devices. Rechargeable batteries are usually the first choice due to their high energy density. However, supercapacitors have a higher power density and longer life-time compared to batteries. READ MORE

4. 2. Paper meets web : how the institution of news production works on paper and online

   Author : Elena Raviola; Jönköping University; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Media and communication studies; Medie- och kommunikationsvetenskap; Business studies; Företagsekonomi;

   Abstract : The dissertation investigates the institution of news production at work, on paper and online, through an ethnographic study at the largest Italian financial newspaper Il Sole-24 Ore. Building on institutional theory and taking inspiration from Bordieu’s theoretical apparatus describing how cultural capital works, the dissertation presents a framework for the way institutions work, a framework that echoes Mary Douglas’ How Institutions Think (1987).

6. 4. Topographical micro-changes in corrugated board production : effects on flexographic post-print quality

   Author : Marcus Rehberger; Nils Enlund; Gunnar Engström; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; corrugated board; liner; double-facer; double-backer; gloss; surface roughness; micro structure; wear; paper metal friction; flexo; ink-jet; print quality; Cellulose and paper engineering; Cellulosa- och pappersteknik;

   Abstract : The appearance and design of a package are key properties to attract and to focus the attention of a customer. Print quality contributes to a great degree to achieve these requirements. Most critical perceived in terms of quality are print defects like mottling, gloss and stripiness, which all appear in the printing of corrugated board. READ MORE
