Characterization of microstructural, mechanical and thermal properties and ageing study of Th–3 wt.% U alloy

This article aimed to obtain more information on the microstructural, mechanical, thermo-physical, and ageing aspects of the Th-3 wt.% U alloy. The thermal conductivity of the Th-3U alloy was found at room temperature using the transient plane source (TPS) technique. It was found that the room temperature thermal conductivity of Th–3U alloy (35.6 W/m◦C) is superior to that of unalloyed uranium, existing oxide, and metallic fuel materials....

Significantly Enhanced and Precisely Modeled Thermal Conductivity in Polyimide Nanocomposites by Chemically Modified Graphene via in-situ Polymerization and Electrospinning-hot press Technology

Chemically modified graphene (CMG) was obtained by combining aminopropyllsobutyl polyhedral oligomeric silsesquioxane (NH2-POSS) and hydrazine monohydrate to functionalize graphene oxide (GO). CMG and polyimide (PI) were combined to create the CMG/PI nanocomposite. The properties of this nanocomposite were obtained using a variety of methods. The thermal conductivity measurements were performed using a TPS instrument by utilizing the transient plane source (TPS) method. It was found that the thermal ...

“Graphene-Like” Exfoliation of Atomically-Thin Films of Bi₂Te₃ and Related Materials: Applications in Thermoelectrics and Topological Insulators

This article examined the properties of bismuth telluride (Bi₂Te₃) after “graphene-inspired” exfoliation left its crystalline films with a thickness of a few atoms. The thermal conductivities were found using the transient plane source (TPS) technique and the laser-flash method. An instrument was used for obtaining the thermal conductivity with the TPS technique. It was found that the exfoliated thin films have low thermal conductivity, relatively ...

A review on modeling of the thermal conductivity of polymeric nanocomposites

This article explored the recent discoveries that have been made regarding the thermal conductivity of polymeric nanocomposites. The thermal conductivities were found using several methods: comparative method, laser flash method, stable state method, the "two thermometer-one heater" method, line-source method and transient plane source (TPS) technique. The TPS technique was used measure the thermal transport properties of nanocomposites in a copolymer matrix....

Heat Transfer Organic Materials: Robust Polymer Films with the Outstanding Thermal Conductivity Fabricated by the Photopolymerization of Uniaxially Oriented Reactive Discogens

Triphenylene-based reactive discotic liquid crystals (DLC), HABET vinyl monomer and THBT thiol cross-linker, were synthesized and applied for the development of advanced heat transfer organic material (HTOM) as a continuous matrix. The thermal conductivity values of the polymerized DLC HTOMs was evaluated using the transient plane source (TPS) technique and laser flash analysis (LFA). The DLC HTOMs that were reported to have high thermal conductivity values and excellent mechanical and ...
