2. 1. Plasticization of Biobased Polymers: A Combined Experimental and Simulation Approach

   Author : Hüsamettin Deniz Özeren; Mikael S. Hedenqvist; Richard Olsson; Fritjof Nilsson; Kim Bolton; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; plasticization; starch; gluten; simulation; molecular dynamics; glycerol; mjukgörning; stärkelse; gluten; simulering; molekyldynamik; glycerol; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : The field of bio-based plastics has developed significantly in recent decades and there is an increasing demand for industries to shift from petrochemical to biobased polymers. Biobased polymers offer competitive properties, and in many cases have advantages in terms of cost. READ MORE

4. 2. Leveraging Intermediate Representations for High-Performance Portable Discrete Fourier Transform Frameworks : with Application to Molecular Dynamics

   Author : Måns Andersson; Stefano Markidis; Artur Podobas; Niclas Jansson; Ivy Bo Peng; Hartwig Anzt; KTH; []
   Keywords : Intermediate Representation; Discrete Fourier Transform; Fast Fourier Transform; Molecular Dynamics; Mellankod; diskret Fouriertransform; snabb Fouriertransform; Molekyldynamik;

   Abstract : The Discrete Fourier Transform (DFT) and its improved formulations, the Fast Fourier Transforms (FFTs), are vital for scientists and engineers in a range of domains from signal processing to the solution of partial differential equations.  A growing trend in Scientific Computing is heterogeneous computing, where accelerators are used instead or together with CPUs.

5. 3. In pursuit of next generation photovoltaics : An electronic structure study of emerging solar cell materials

   Author : Axel Erbing; Michael Odelius; David Scanlon; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Solar cells; computational physics; density functional theory; electronic structure; molecular dynamics; Solceller; beräkningsfysik; täthetsfunktionalteori; elektronstruktur; molekyldynamik; Theoretical Physics; teoretisk fysik;

   Abstract : The development of a new generation of photovoltaic technologies is an important task in order to increase the production of clean energy. Perovskite solar cells, with an exceptionally rapid development over the last decade, have transformed into perhaps the most promising candidate to provide a low-cost alternative to conventional cells.
