ZnO/Ag heteronanostructures with good photocatalytic activity towards photodegradation of methylene blue have been synthesized using a facile thermal decomposition approach.
Graphene oxide (GO) with different ratios of functional groups is prepared via low temperature directional thermal reduction and re-oxidization by nitric acid.
In a previous study, the carbon concentration dependence of the deformation twinning behavior in twinning-induced plasticity steels was investigated, which clarified that the deformation twin fraction in the <144> tensile orientation did not change with the carbon concentration. In this study, twinning deformation occ…
A facile wet chemical method was adopted for preparing highly photoactive nitrogen doped TiO2 (N‐TiO2) powders with visible responsive capability, which could be achieved by the hydrolysis of titanium isopropoxide (TTIP) in the ammonium hydroxide precursor solution in various concentrations and then calcined at differ…
Calcium phosphate- (CaP-) based composite scaffolds have been used extensively for the bone regeneration in bone tissue engineering. Previously, we developed a biomimetic composite nanofibrous membrane of gelatin/β-tricalcium phosphate (TCP) and confirmed their biological activity in vitro and bone regeneration in viv…
The chemical interaction between calcium chloride (CaCl2) and cementitious binder may alter the transport properties of concrete which are important in predicting the service life of infrastructure elements. This paper presents a series of fluid and gas transport measurements made on cementitious mortars before and af…
采用溶胶–凝胶静电纺丝技术制备无铅压电K0.5Na0.5NbO3 (KNN)纳米纤维，研究了退火温度和纺丝电压等对纳米纤维物相和形貌的影响。结果表明，退火处理后的纳米纤维是正交钙钛矿结构的KNN材料。随着退火温度的升高，纳米纤维的平均晶粒尺寸逐渐增大。当纺丝电压为6~12 kV时，KNN纳米纤维的直径随着电压的增大呈现先增加、后减小的趋势。将KNN纳米纤维在不同间距的叉指电极上进行组装，可获得能够输出交流脉冲电压的压电发电元件。输出电压的幅值可达190~430 mV，并随叉指电极间距的增加而增大。The lead-free K0.5Na0.5NbO3 (KNN) nanofibers were fabricated through…
9%Cr-1%Mo martensitic-ferritic steels are used in power plant components with operating temperatures of around 600 °C because of their good mechanical properties at high temperature as well as good oxidation resistance. These steels are generally used in the normalized and tempered condition. This treatment results in…
The problem with the waste from electric and electronic equipment (WEEE), consisting of about 80% of television sets and computers containing a cathode ray tube (CRT) have just begun to deal with. Cathode ray tubes (CRTs) are the video display components of televisions and computer monitors (EPA, 1995). Arising proble…
One of the permanent methods to store anthropogenic CO 2 is to convert it into thermodynamically stable mineral carbonates. Depending on the reaction pathways and the reaction conditions such as temperature, partial pressure of CO 2, composition and concentration of the reaction fluid and reactants, different phases o…
The research area of plasmonics promises devices with ultrasmall footprint operating at ultrafast speeds and with lower energy consumption compared to conventional electronics. These devices will operate with light and bridge the gap between microscale dielectric photonic systems and nanoscale electronics. Recent rese…
Reduced graphene oxide–carbon nanotube (rGO–CNT) hybrids have been synthesized by electrodeposition of GO stabilized CNT using indium tin oxide (ITO) as working electrode, followed by electrochemical reduction of GO–CNT into rGO–CNT.
A hierarchical copper nanoassembly was synthesized by solvothermal treatment at 150 °C for 2 h in the absence of any templating agents, and exhibited excellent air-stability, antioxidative properties and catalytic reduction of 4-nitrophenol.
Results of density functional theory calculations on possible mechanisms for formation of the diterpenoid cyclooctatin are described. These results are consistent with the involvement of an unexpected 1,3-alkyl shift that interconverts two cyclopropylcarbinyl carbocations and interchanges the positions of two carbon a…
The synergistic effect of Cu 2 (OH)PO 4 /H 2 O 2 and g-C 3 N 4 highly boosts the catalytic activity towards photo-Fenton photocatalytic degradation of rhodamine B.
Rapamycin-induced protein heterodimerization of FKBP12 and FRB is one of the most commonly employed switches to conditionally control biological processes. We developed an optically activated rapamycin dimer that does not induce FKBP12-FRB dimerization until exposed to light, and applied it to control kinase, protease…
PLA/18% nHA–2% Ag and PLA/18% nHA–6% Ag nanocomposites showing zone of inhibition against E. coli .
Hollow alloyed nanoparticles (NPs) represent one kind of promising fuel cell electrocatalyst. However, the formation of single-cavity hollow structures by a dealloying process is quite challenging owing to the random leaching/dissolution of transition metals, surface passivation and the limited diffusion distance of t…
High-perfection Ni/Co spinel microcrystalline catalysts with extensive faceting show high turnover frequencies in methane dry reforming and good sulfur tolerance.
Polymer gels are subjected to large-strain deformation during their applications. The gel deformation at large-strain is non-linear and can often lead to failure of the material. Here, we report the large-strain deformation behavior of a physically cross-linked, swollen triblock copolymer gel, which displays unique st…
