2. 1. Organic Materials-based Electrochemical Flow Cells for Energy Applications

   Author : Penghui Ding; Reverant Crispin; Viktor Gueskine; Mikhail Vagin; Brian Seger; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : To meet the 2015 Paris Agreement requirement of limiting global warming to 1.5 °C, the transition from fossil fuels to renewables (solar and wind) necessitates a rapid change of the energy landscape. READ MORE

4. 2. But What Do They Mean? : Modelling Contrast Between Speakers in Dialogue Signalled by “But”

   Author : Kavita Elisheba Thomas; Colin Matheson; Keith Stenning; Johanna Moore; Ivana Kruijff-Korbayova; University of Edinburgh; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; English dialogue; discourse markers; coherence relations;

   Abstract : Understanding what is being communicated in a dialogue involves determining how it is coherent, that is, how the successive turns in the dialogue are related, what the speakers’ intentions, goals, beliefs, and expectations are and how they relate to each other’s responses. This thesis aims to address how turns in dialogue are related when one speaker indicates contrast with something in the preceding discourse signalled by “but”. READ MORE

6. 4. High performing cast aluminium-silicon alloys

   Author : Martin Riestra; Salem Seifeddine; Ehsan Ghassemali; Jessica Elfsberg; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminium cast alloys; melt quality; eutectic modification; grain refinement; microstructure; tensile properties;

   Abstract : The need to produce lighter components due to environmental aspects and the development of electrical vehicles represents an opportunity for cast aluminium-silicon alloys. With high specific strength, good castability, high corrosion resistance and recyclability, these alloys offer an attractive combination of properties as an alternative to steel, cast iron and titanium-based components in certain applications.

7. 5. Mesoporous transition metal oxides for oxygen electrocatalysis in energy conversion technologies

   Author : Zhixing Wu; Emma Björk; Magnus Odén; Mikhail Vagin; Freddy Kleitz; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Electrocatalysis, the foundation of electrical to chemical energy transformation, enables the mitigation of the electrical energy losses during reactions and the control of selectivity of the process to certain chemical products. The slow rate and the multi-step complexity of oxygen-associated reactions, namely oxygen reduction reaction (ORR) and oxygen evolution reaction (OER), motivate the use of platinum group metals (PGM) catalysts, which significantly increase the price of the technologies due to the cost and scarcity of PGM-based materials.
