TLDR
The general theory of the transient plane source (TPS) technique is outlined in some details with approximations for the two experimental arrangements that may be referred to as "hot square" and "hot disk" as discussed by the authors.Abstract:
The general theory of the transient plane source (TPS) technique is outlined in some details with approximations for the two experimental arrangements that may be referred to as ‘‘hot square’’ and ‘‘hot disk.’’ Experimental arrangements and measurements on two materials, Cecorite 130P and Corning 9606 Pyroceram, using a hot disk configuration, are reported and assessed.read more

Exfoliation and characterization of bismuth telluride atomic quintuples and quasi-two-dimensional crystals.
TL;DR: A method for "graphene-inspired" exfoliation of crystalline bismuth telluride films with a thickness of a few atoms is described, paving the way for producing stacks of crystallines bism Ruth Telluride quantum wells with the strong spatial confinement of charge carriers and acoustic phonons, beneficial for thermoelectric devices.

Graphene-enhanced hybrid phase change materials for thermal management of Li-ion batteries
TL;DR: In this paper, a combination of the sensible and latent heat storage together with the improved heat conduction outside of the battery pack leads to a significant decrease in the temperature rise inside a typical Li-ion battery pack.

Thermal transport studies of electrically conducting materials using the transient hot-strip technique
TL;DR: The transient hot-strip (THS) method has been used for thermal conductivity and thermal diffusivity studies of electrically conducting materials by introducing a thin electrically insulating layer between the hot strip and the metallic material under study as discussed by the authors.
