1. 1. Spin ice under uniaxial pressure and magnetic frustration in garnets

   Författare :Richard Edberg; Patrik Henelius; Santiago A. Grigera; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magnetism; fysik; spin is; frustrerad magnetism; värmekapacitet; heat capacity; spin ice; physics; magnetism; Material and Nano Physics; Material- och nanofysik;

   Sammanfattning : Frustration is the inability to simultaneously satisfy all interactions. The interest in magnetic frustration has grown during the last decades. The research has among other findings been promoted by the discovery of spin ice which is a frustrated magnetic compound with an exotic ground state and unusual excitations. LÄS MER

   Sammanfattning : Carbon capture and storage (CCS) is one of the most promising technologies that may significantly reduce CO2 emissions. A better understanding of the thermo-physical properties of CO2 mixtures is required for the design and operation of different CCS processes. LÄS MER

4. 3. Biological growth on rendered façades

   Författare :Sanne Johansson; Avdelningen för Byggnadsmaterial; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; temperature; render; radiation; photosynthesis; moulds; mosses; mortar; moisture; lichens; Imaging-PAM; humidity; heat capacity; heat; ETICS; algae; biological growth; calorimetry; desiccation tolerance;

   Sammanfattning : Biological organisms have an incredible ability to adapt to almost any environment and the humans activities on earth have created many new habitats for different kinds of organisms. For example can certain organisms grow on rocks and vertical cliffs, and when humans started building houses with mineral based façades, some organisms found that these were new habitats to live on.

5. 4. Membrane-based nanocalorimetry for low temperature studies with high resolution and absolute accuracy

   Författare :Stella Tagliati; Andreas Rydh; Vladimir M. Krasnov; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanocalorimetry; specific heat; membrane-based calorimeter; AC steady state; frequency dependence; thermal link conductance; thermal relaxation; GeAu thermometer; numerical simulations; fysik; Physics;

   Sammanfattning : A differential, membrane-based nanocalorimeter has been designed and constructed for thermal studies of mesoscopic samples at low temperatures. The calorimeter is intended for sample masses from mg to sub-μg and a broad temperature range from above room temperature down to the sub-K region. LÄS MER

7. 5. Impacts of Thermo-Physical Properties on Chemical Absorption for CO2 Capture

   Författare :Worrada Nookuea; Jinyue Yan; Hailong Li; Eva Thorin; Bin Liang; Xiaoyan Ji; Jesus Zambrano; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : Following the climate change mitigation target in Paris agreement, the global warming has to be limited to 2.0°C above the preindustrial levels. One of the potential methods is carbon capture and storage (CCS), which can significantly reduce the CO2 emissions from the vast point sources such as power plants, industries, and natural gas processes.
