4. 2. Superabsorbent Polymers from the Cell Wall of Zygomycetes Fungi

   Author : Akram Zamani; Högskolan i Borås; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; chitosan; cell wall; chitin; polyphosphates; dilute sulfuric acid; zygomycetes fungi;

   Abstract : The present thesis presents new renewable, antimicrobial and biodegradable superabsorbent polymers (SAPs), produced from the cell wall of zygomycetes fungi. The cell wall was characterized and chitosan, being one of the most important ingredients, was extracted, purified, and converted to SAP for use in disposable personal care products designed for absorption of different body fluids.

5. 3. Design, Synthesis and Properties of Bipyridine-capped Oligothiophenes for Directed Energy and Electron Transfer in Molecular Electronic Applications

   Author : Lasse Nurkkala; Simon Dunne; Sarah Angus-Dunne; Edwin Constable; Mälardalens högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Molecular Electronics; Organic Synthesis; Ruthenium; Pyridyl Complexes; Ligand Design; Chemical engineering; Kemiteknik; Biotechnology Chemical Engineering; bioteknik kemiteknik;

   Abstract : The earliest landmark in computer technology was construction of the Electronic Numerial Integrator and Computer, ENIAC. Computational switching was performed with vacuum tubes and relays, rather large in size, making this computer rather unwieldy. READ MORE

6. 4. Biomass Pre-treatment for the Production of Sustainable Energy : Emissions and Self-ignition

   Author : Katarina Rupar-Gadd; Mehri Sanati; Evert Ljungström; Växjö universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; terpenes; SPME; biomass; pellets; self-ignition; storage; drying; calorimetry; Chemical engineering; Kemiteknik; Bioteknik; Biotechnology;

   Abstract : Organic emissions with focus on terpenes, from biomass drying and storage were investigated by Solid Phase Microextraction (SPME) and GC-FID and GC-MS. The remaining terpenes in the biomass (Spruce and pine wood chips) after drying were dependant on the drying temperature and drying medium used. READ MORE

7. 5. Molecular Electronic Devices based on Ru(II) Thiophenyl Pyridine and Thienopyridine Architecture

   Author : Robert Steen; Simon Dunne; Sarah Angus-Dunne; Kenneth Wärnmark; Mälardalens högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Molecular Electronics; Organic Synthesis; Ruthenium; Pyridyl Complexes; Ligand Design; Fused Ligands; Chemical engineering; Kemiteknik; Biotechnology Chemical Engineering; bioteknik kemiteknik;

   Abstract : According to the famous axiom known as Moore’s Law the number of transistors that can be etched on a given piece of ultra-pure silicon, and therefore the computing power, will double every 18 to 24 months. However, around 2020 hardware manufacturers will have reached the physical limits of silicon. READ MORE
