We present a method for measuring changes in the atmospheric O2/N2 ratio based on data from a gas chromatograph (GC) equipped with a thermal conductivity detector (TCD). In this method, O2 and N2 in an air sample are separated on a column filled with molecular sieve 5A with H2 carrier ...

Anisotropic thermal conductors, in which heat flows faster in one direction than in another, can be characterized by the thermal conductivity anisotropy ratioρ(= κf/κs) between the thermal conductivities along the fast axis (κf) and the slow axis (κs). One common way to engineerρin...

Carrier gas (typically helium which has very high thermal conductivity) flows across the filaments eliminating heat at a constant rate. When a sample component with lower thermal conductivity exits the column and flows across the sample filaments, the temperature of the filaments increases, un...

SHS has become the most developed and widely used heat storage technology due to its simple principle and easy operation [27,28].The ideal SHS material should have good physical and chemical properties of large specific heat capacity, high density, high thermal conductivity, and low vapor pressure...
Daniel Péré1, Alain Jacob1, Kenzo Moriya1, Bruno Delatouche1, Pascal Roussel3, Georg Madsen4 & Gilles Dennler1 In order to reduce the thermal conductivity of CoSbS, a newly developed thermoelectric semiconductor, we have aimed at intentionally induce atomic disorder in its str...
Hf2CO2 is determined to exhibit a thermal conductivity better than MoS2 and phosphorene. The room-temperature thermal conductivity along the armchair direction is determined to be 86.25~131.2 Wm−1 K−1 with a flake length of 5~100 μm. The room temperature thermal expansion coefficient ...
