The influence of electroless silver layer on the electrochemical behavior of steel cathode current collector was examined in rechargeable alkaline MnO2-Zn batteries. For that purpose, batteries were dismantled after various stages of charge/discharge cycles, followed by polarization measurements and morphological anal…
We construct a density functional theory (DFT) for the sticky hard sphere (SHS) fluid which, like Rosenfeld's fundamental measure theory (FMT) for the hard sphere fluid [Phys. Rev. Lett. {\\bf 63}, 980 (1989)], is based on a set of weighted densities and an exact result from scaled particle theory (SPT). It is demonst…
The switching behaviors of ionic/electronic mixed conductor-based solid electrolyte nonvolatile memories have been attributed to repetitive formation and breakage of the conductive pathways inside a solid electrolyte. However, direct evidence of such pathway existence and their formations has never been provided. Here…
Effects of Si and Cr contents on bainite microstructure of medium carbon steels have been examined in order to obtain further information for good strength–ductility balanced spring steel. Four practical medium carbon steels, S55C, SUP9, SUP7 and SUP12 were isothermally transformed at temperatures between 300°C and 50…
Selective Laser Melting (SLM) is a layered manufacturing process that allows to build complex, lightweight and customized parts by consolidating successive layers of powder. Since during the SLM process the powder material is completely molten, a low degree of porosity and good mechanical properties can be achieved. H…
The kinetics of the liquidphase hydrogenation of furfuraldehyde to furfuryl alcohol over Ir catalysts supported over TiO2 was studied in the temperature range of 323 to 373 K. The effect of furfural concentration, hydrogen pressure and the solvent effect were also studied. A high selectivity towards furfuryl alcohol…
After the observation of serious environmental damages resulting from industrial activities, air pollution reduction has become globally very important. Fuels and flue gas desulfurization methods in power plants are applicable for petroleum derived fuels consuming units. But in coal fuel power plants, only Flue Gas De…
Regular methods for detecting partial discharge of transformers include the pulse electric current,the dissolved gas analysis(DGA),the ultrasound,the radio interference voltage(RIV),the light detection,the radio frequency,the chemical method,etc.According to the principle of the above methods and the characteristic of…
The uniaxial different frequency cyclic loadings and unloading tests on biotite granite comes from the Changjiang of Hainan nuclear power first-stage construction major factory district are done on the RMT-150B multi-function automatic rigid rock servo material testing machine. The law between cyclic frequency and dyn…
Intrinsically disordered proteins (IDPs) are a new class of proteins which lack a unique tertiary structure under native conditions while possessing essential biological functions. They take part in various physiological processes such as signal transduction, transcription and translation regulation, and protein modif…
Gradient-banding and vorticity-banding instabilities, as well as a shear-induced instability due to shear-gradient induced mass transport will be discussed. Various scenarios that underly these instabilities are addressed and simple constitutive relations that allow for a (semi-) quantitative analysis are proposed. A…
The main disadvantage of the switched reluctance motor is torque ripple.Based on direct instantaneous torque control,the effect of torque ripple was analyzed from the point view of basic space voltage vector.A novel method was proposed for the optimization of the direct controlling torque.It improved the performance o…
Lead bismuth eutectic(PbBi) has been proposed as the candidate spallation target and coolant material for Accelerator Driven sub-critical Systems(ADS) as well as coolant material for fast neutron reactor,the liquid PbBi loop is the necessary experimental platform for the study of PbBi-related technologies.The series o…
Article Chemical Modification of Polyvinylidene Fluoride (PVDF) Membrane and Its Application to Milk Purification was published on January 1, 2010 in the journal International Journal of Nonlinear Sciences and Numerical Simulation (volume 11, issue 1).
Stable Bi2S3 colloidal nanocrystals with sphere or rod shape were synthesized through a "hot injection" method using organic molecules and macromolecules as ligands. The morphology of Bi2S3 nanocrystals is highly dependent on the experimental parameters, including the reaction temperature, reaction time, reactant rati…
The effect of the grinding of raw Japanese cedar chip as a model material of woody materials by a new type ball mill, namely converge mill, was studied for the effective enzymatic saccharification. We achieved almost 100% of saccharification degree from ground cedar powder prepared by the converge mill. The grinding t…
Increased efficiency of industrial standard solar cells can be realized on thin (<150 μm) mc-Si wafers by improving the rear surface with a dielectric passivation and local contacts. In this paper, we are presenting the successful implementation of an industrially feasible process sequence optimized for multi-crystall…
The performance of LiNi 1 / 3 Mn 1 / 3 Co 1 / 3 O 2 depends largely on the distribution of transition-metal (TM) ions over the available lattice sites within the layered rocksalt structure. Despite predictions that the TM ions take on an ordered arrangement described by a 3 × 3 R 30 ° supercell, little experimental ev…
Electromigration behavior of SAC flip-chip joints with respect to the crystallographic orientation of Sn grains was investigated. The test sample had direct contact of Sn-3.0wt% Ag-0.5wt% Cu on Cu-OSP (organic surface preservative) and the applied current density was 15 kA/cm2 at 160 °C. Without current stressing, no…
Ceramic column grid array packages have been increasing in use based on their advantages such as high interconnect density, very good thermal and electrical performance, compatibility with standard surface-mount packaging assembly processes, and so on. CCGA packages are used in space applications such as in logic and…
