  2. 11. Structure determination of beam sensitive crystals by rotation electron diffraction : the impact of sample cooling

    Author : Fei Peng; Junliang Sun; Xiaodong Zou; Dag Nores; Ute Kolb; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; electron crystallography; rotation electron diffraction; structure determination; cooling; Inorganic Chemistry; oorganisk kemi;

    Abstract : Electron crystallography is complementary to X-ray crystallography. Single crystal X-ray diffraction requires the size of a crystal to be larger than about 5 × 5 × 5 μm3 while a TEM allows a million times smaller crystals being studied. This advantage of electron crystallography has been used to solve new structures of small crystals. READ MORE

  4. 12. Intranasal Cooling for Cerebral Hypothermia Treatment

    Author : Lucian Covaciu; Sten Rubertsson; Jan Weis; Peter Andrews; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Selective brain cooling; cerebral hypothermia; therapeutic hypothermia; cardiac arrest; stroke; traumatic brain injury; brain temperature; magnetic resonance spectroscopy; trigeminal reflex; Intensive care; Intensivvård; Radiology; Radiologi; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Abstract : The controlled lowering of core body temperature to 32°C to 34°C is defined as therapeutic hypothermia (TH). Therapeutic hypothermia has been shown to improve neurological outcome and survival in unconscious patients successfully resuscitated after cardiac arrest. READ MORE

    Abstract : Refrigeration plays a crucial role in many different sectors and consumes about 17% of the electricity produced globally. This significant energy consumption implies large share of refrigeration in primary energy consumption and other environmental impacts. READ MORE

  6. 14. Ionic Liquid Based Electrolytes for High-Temperature Lithium-Ion Batteries

    Author : Manfred Kerner; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EMITFSI; EMIFSI; electrolyte; ionic liquid; lithium-ion battery; high-temperature stability; LiFSI;

    Abstract : Today, lithium-ion batteries (LIBs) are ubiquitous in mobile phones, laptops, and other portable devices. The research community strives to further improve the LIB to increase electric driving distance and efficiency of both hybrid electric vehicles (HEVs) and fully electric vehicles (EVs). READ MORE

  7. 15. Gothenburg District Cooling System - An evaluation of the system performance based on operational data

    Author : Maria Jangsten; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building chilled water systems; district cooling; high temperature district cooling; low delta-T;

    Abstract : The global energy demand for providing cooling in buildings is expected to increase the next decades, along with a rapid growth in the number of air conditioners and chillers. A more energy efficient, economical and environmentally viable solution to this increased cooling demand, is district cooling. READ MORE
