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....

“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 ...

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 ...

Characterization of microstructural, mechanical and thermophysical properties of Th-52U alloy

This article studied the microstructural features of thorium-52 wt.% uranium alloy (Th-52U). Several thermal properties were also evaluated to assess the use of this alloy as a prospective fuel. The transient plane source (TPS) technique was used for evaluating the thermal conductivity of Th-52U alloy using slab specimen geometry. The experimentally determined thermal conductivity value of Th-52U alloy was found to be 25.6 W/m°C, which is ...

Anisotropy measurements of a cuboid of nanostructured hydrothermally prepared Bi_0.45Sb_1.55Te₃

Thermoelectric materials can be used to convert waste heat, such as solar energy and automobile exhaust, to electricity. A Bi_0.45Sb_1.55Te₃ p-type cuboid was created using hydrothermal synthesis, cold pressing, and evacuated-and-encapsulated sintering in a Pyrex ampoule. The figure of merit (z) was determined by finding three transport parameters: electrical conductivity, thermopower, and thermal conductivity. The thermal conductivity measurements on the three (A, ...
