The thermal properties of single-crystal diamond nanowires (NWs) have been calculated from first principles but have never been measured experimentally. Taking advantage of the sharp geometry of samples analyzed in a laser assisted atom probe.

Measurements of rock thermal conductivity with a Transient Divided Bar. [EN]

Authors of the publication: - V Pasquale - Verdoya M - Chiozzi P

An apparatus (Transient Divided Bar - TDB) was implemented to determine the thermal conductivity of rocks. TDB consists of a stack of elements, which comprise a rock specimen placed between two copper blocks of cylindrical shape with known thermal capacity, initially kept at room temperature.
