Highly oriented [1 1 0] Bi2Te3 films were obtained by pulsed electrodeposition. The structure, composition, and morphology of these films were characterized. The thermoelectric figure of merit (zT), both parallel and perpendicular to the substrate surface, were determined by measuring the Seebeck coefficient, electrical conductivity, and thermal conductivity in each direction. At 300 K, the in-...

In past decades, carbon–carbon composites composed of multidirectional carbon fiber reinforcement embedded in carbon matrix have been significantly explored due to its excellent mechanical and physical properties. Carbon-carbon composites have light weight, high strength at high temperature in non-oxidizing atmospheres, low coefficient of thermal expansion, high electrical conductivity and high...

The irreversibility of heat conduction in porous media, its relation to effective thermal conductivities (ETCs), and the optimization of thermal conduction process are investigated in this work based on the concept of entransy dissipation. Two more new concepts of reference entransy dissipation and nondimensional entransy dissipation are first introduced. Then it is showed that the nondimension...

In the present Rapid Communication we present an analytical and numerical solution of the self-consistent mode-coupling equations for the problem of heat conductivity in one-dimensional systems. Such a solution leads us to propose a different scenario to accommodate the known results obtained so far for this problem. More precisely, we conjecture that the universality class is determined by the...

The thermoelectric figure of merit (ZT) of a single β-Silicon Carbide (SiC) nanowire (NW) was measured using the four-point three-omega (3-ω) method for the first time. The electrical conductivity (σ), thermal conductivity (κ), and Seebeck coefficient (S) were measured on the same measurement platform consisting of four point probe. To this end, we developed a novel technique in which focused i...

application of feed pellets in animal and aquatic farming industries has grown because of both the physical and the nutritional benefits it provides. development of feed pellets manufacturing industry is also considerable. steam conditioning process, which plays an important role in pelleting production, includes heating feed particles, adding moisture, and mixing the mash. pellets cooling and ...
