2. 1. Properties in New Complex Perovskite-Related Materials, a Matter of Composition and Structure

   Author : Samrand Shafeie; Gunnar Svensson; Jekabs Grins; John T. S. Irvine; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Perovskite; XANES; XRPD; NPD; TEC; TEM; SEM; TGA; SAED; HREM; thermal expansion; Seebeck coefficient; electronic conductivity; SOFC materials; magnetic susceptibility; Perovskit; XANES; XRPD; NPD; TEC; TEM; SEM; TGA; SAED; HREM; termisk expansion; Seebeck koefficient; elektrisk ledningsförmåga; SOFC material; magnetiska egenskaper; Materials Chemistry; materialkemi;

   Abstract : This PhD thesis presents investigations of perovskite-related compounds in systems of interest for applications in components in solid oxide fuel cells. The compound compositions derive from substitutions in the parent compounds LaCoO3, LaCrO3 and SrFeO3. READ MORE

4. 2. Thermal detector with integrated absorber structure for mid-IR gas detection

   Author : Shakeel Ashraf; Göran Thungström; Peter Enoksson; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal detectors; Thermopile detectors; Infrared absorbers; SU-8 epoxy; Interferometric and Multi-layered absorber; Seebeck coefficient; Molybdenum di-sulfide;

   Abstract : Measurement of the concentration of greenhouse gases, such as carbon dioxide(CO 2 ) and methane (CH 4 ), in the atmosphere has received significant attention in the last few decades. This work focusses on the development of high-performance thermopile detectors for use with the non-dispersive infrared (NDIR) measurements of such gases. READ MORE

5. 3. Thermoelectric Ba8Ga16Ge30 clathrates for waste heat recovery

   Author : Daniel Cederkrantz; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; thermal stability; substitution; thermal conductivity; Seebeck coefficient; electrical resistance; Clathrates; Ba8Ga16Ge30; waste heat recovery; semiconductors;

   Abstract : The modern, highly industrialized, society of today requires huge amounts of energy to function. This has resulted in a heavy dependence on the very energy efficient fossil fuels, a source of energy which of course is not infinite and we are slowly approaching the day when oil runs out.

   Abstract : The world’s increasing demand for energy and supplying this energy dominantlyfrom fossil fuels has a major impact on global climate change. Theenergy crisis has gotten more alarming in the recent years which increasedthe motivation for replacing fossil fuels with greener routes for energy harvest. READ MORE

7. 5. Thermoelectric properties of conducting polymers

   Author : Olga Bubnova; Xavier Crispin; Magnus Berggren; Alan Kaiser; Linköpings universitet; []
   Keywords : Thermoelectric generation; Seebeck coefficient; conducting polymers; thermoelectric efficiency.;

   Abstract : According to different sources, from forty to sixty percent of the overall energy generated in the world today is squandered in waste heat. The existing energy conversion technologies are either close to their efficiency limits or too costly to justify their implementation. READ MORE
