Large size bismuth telluride based polycrystalline alloys have been prepared to investigate the texture-related anisotropy of thermoelectric properties. X-ray diffraction analysis indicated that n-type alloy was more easily (001) oriented than p-type one. Both electrical and thermal conductivities showed strong in textured samples, while Seebeck coefficient ZT were almost isotropic. However, as measured along different directions, could be overestimated up ∼60%. A relationship between...
A comparable study of the microstructure and magnetic properties was performed for magnetite films deposited on (100)-oriented MgO SrTiO3 (STO) substrates. The growth strained high quality Fe3O4 confirmed by x-ray diffraction analysis Raman spectroscopy measurements. surface morphology two were found to be obviously different. Moreover, a stripelike domain structure observed in film STO. Substrate-induced strain is believed responsible these observations, which significantly affects...
Some key experiments are carried out to determine the solubility of N in Fe–Si liquid solutions at various compositions, temperatures, and 2 pressures using sampling method. The Fe–Si–N system is thermodynamically modeled CALculation PHAse Diagrams (CALPHAD) approach for first time based on critical evaluation all available experimental data. In present thermodynamic modeling, solid described modified quasichemical model compound energy formalism, respectively. particular, Gibbs energies...
(Zr,Hf)NiSn -based half-Heusler thermoelectric materials have been prepared by melt spinning and spark plasma sintering to refine the grain size. The sizes of melt-spun thin ribbons varied from ~500 nm ~3 μm no significant growth were found for bulk samples compacted sintering. Nanoscale precipitates dispersed in matrix observed, which should be more metallic due increase electrical conductivity. reduction lattice thermal conductivity was observed refined sizes.
Structure, magnetic and transport properties of polycrystalline Fe3O4–Ge nanocomposite films fabricated using a reactive cosputtering method have been examined. It is found that with the increase in Ge content, Fe3O4 grain size decreases crystallization grains becomes poor. The are ferromagnetic at room temperature, their saturation magnetization content. room-temperature resistivity, much higher than pure films, increases increasing content because poor appearance barriers boundaries....
The HCN laser on EAST is a continuous wave glow discharge with 3.4 m cavity length and 120 mW power output at 337 μ wavelength. Without temperature-controlled system, the of very sensitive to environmental temperature. An external feedback control system applied stabilize power. composed stepping motor, PLC, supervisory computer, corresponding program. One step distance motor 1 time response 0.5 s. Based stable for obtained more than eight hours, which satisfies experiment.
The structure and thermal stability of Mo/Al multilayers prepared by a four facing target sputtering system have been studied. Cross-sectional high-transmission electron microscopy reveals that Mo Al layers are polycrystalline the thickness mixed at Mo-on-Al interfaces is larger than Al-on-Mo interfaces. Annealing treatment up to 450?C leads gradual period expansion appearance 5th 6th order Bragg peak, which can be attributed grain growth sharpness and/or improvement correlations roughness...
An interactive tool to visualize the K-string composition of long DNA sequences including bacterial complete genomes is described. It especially useful for exploring short palindromic structures in sequences. The SeeDNA program runs on Red Hat Linux with GTK+ support. displays two-dimensional (2D) or one-dimensional (1D) histograms distribution a given sequence and/or its randomized counterpart. also capable showing difference distributions between two C source code using package freely available.
Abstract In order to analyze the effect of thermal ageing on creep rupture mechanism and establish a method for predicting life P92 heat-resistant steel under ageing, tests were performed specimens, aged at 650 °C different times applied stresses. Optical microscopy scanning electron utilized observe microstructure after rupture. Voids cracks distributed in grains before whereas voids clearly around M 23 C 6 precipitates Laves phase along sub-grain boundaries ageing. The damage tolerance...
Organic phase change materials (PCMs) are commonly used for battery thermal management. petroleum-based PCMs such as paraffin have an adverse effect on environment. Fatty acids environmentally friendly bio-based PCMs, enormous potential in sustainable development strategies. Nevertheless, the application of fatty management (BTMS) is restricted by leakage liquid PCM, poor performance and improper temperature. We proposed a novel eutectic composite (CPCM) with enhanced conductivity excellent...

Microbiologically influenced corrosion (MIC) has long been a critical issue due to its potential cause severe damage equipment and the associated risk of operational failures, leading significant financial losses. This study investigates resistance MIC caused by sulfate-reducing bacteria (SRB) in four types pipeline steel materials, which are soon be introduced market. Two these materials have alloyed with copper during metallurgical process. The uniform rates copper-alloyed were found 0.012...
