  1. 6. Development and characterization of a membrane-based nanocalorimeter for low temperatures

    Författare :Stella Tagliati; Andreas Rydh; Javier Rodríguez Viejo; Stockholms universitet; []
    Nyckelord :;

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

  7. 10. Biogeochemical processes in frozen soils : unfrozen water in frozen soils and factors regulating carbon mineralization at low temperatures

    Författare :Stina Harrysson Drotz; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : High latitude ecosystems are important for global carbon (C) balances and are among the most sensitive ecosystems to climate change. Microbial CO2 production in soil is known to proceed at temperatures < 0ºC in these regions and winter CO2 emissions can significantly affect annual C balances. LÄS MER
