Znx Cd1-x S(0x1) nanowires with several different compositions were successfully synthesized on Si wafers by a simple vapor deposition method using Au as a catalyst.The morphology and composition of the nanowires were investigated by scanning electron microscopy,transmission electron microscopy,and energy dispersive X…
High strain rate triaxial-forging(HSRTF) was successfully conducted on three Mg–Zn–Zr alloys by using a pneumatic power hammer. The microstructure evolution and mechanical properties of the forged alloys were investigated. The results show that HSRTF significantly refined the grains due to dynamic recrystallization(DR…
A fundamental goal in nano-toxicology is that of identifying particle physical and chemical properties, which are likely to explain biological hazard. The first line of screening for potentially adverse outcomes often consists of exposure escalation experiments, involving the exposure of micro-organisms or cell lines…

Removal of brittle materials in the brittle or ductile mode inevitably causes damaged or strained surface layers containing cracks, scratches or dislocations. Within elastic deformation, the arrangement of each atom can be recovered back to its original position without any defects introduced. Based on surface hydroxy…
The true stress-true strain curves have been attained through the isothermal compression experiment of TC18 titanium alloy. The influence of deformation parameters on the shape of stress-strain curves and peak stress has been analyzed through the working-hardening and dynamic softening effects. The true stress-true st…
Novel thermoresponsive polymer conjugates based on microbial polyesters and poly-N-isopropyl acryl amide, PNIPAM, have been reported. The unsaturated poly-3-hydroxy alkanoates, poly (3-hydroxy undecenoate), PHU, and 1:1 mixture of 10-undecenoic acid and soy oil acids, PHU-Sy, were brominated by using bromine in the da…
Saccharina is one of the most important cold-water living marine brown algal genera.In this study we analyzed the transcriptome of S.japonica,which belongs to the 1 000 Plants(OneKP) Project,by using a nextgeneration high-throughput DNA sequencing technique.About 5.16 GB of raw data were generated,and 65 536 scaffolds…
In solid processing systems,electrostatic problems are commonly observed for granules of various shapes.However,a complete understanding of the basic dependence of electrostatic charge generation on particle shape has yet to be established.This observation motivated the present study on examining the effect of granula…
1 Introduction Lithium resources are widely distributed in the oilfield brine from the Nanyishan district in the Qaidam Basin(Fan et al.,2007).The investigation of the thermodynamics and phase diagram of the brine system is valuable in providing the theoretic foundation and scientific guidance in the comprehensive exp…
MnOx(0.4)-CeO2 was investigated for soot oxidation assisted with a pulse dielectric barrier discharge(DBD).The catalysts were evaluated and characterized with TPO(temperature programmed oxidation),X-ray diffraction(XRD),Raman and X-ray photoelectron spectroscopy(XPS).The ignition temperature Ti for soot oxidation decr…
Two new different Cu(Ⅱ) MOFs with the same 1,3,5-tris(1-imidazolyl) benzene(tib) ligand {[Cu(tib)2]·(H2O)2·Br2}n(1) and {[Cu2(tib)·Br·Cl]·2Br}n(2) were obtained by one pot synthesized of tib with CuBr in the presences of HCl and water. X-ray single crystal diffraction analyses indicate that both complexes 1 and 2 have…
This paper investigates the structural state and physical and mechanical properties of austenitic steel 55Kh20G9AN4 treated with concentrated fluxes of nitrogen ions. It is shown that ion beam treatment of the steel at temperatures of 620–870 K is accompanied by the formation of nitrogen modified layers up to 50 μm th…
Electrochemical impedance spectroscopy (EIS) is an important characterization technique for solid oxide fuel cells (SOFCs); however, the overlap or dispersion in the frequency domain among physically distinct processes imposes great difficulties on unambiguous interpretation of EIS data. Built upon mechanistic SOFC mo…
