Two mononuclear bis(oxamato) complexes with the formula [nBu4N]2[M(2,3-acbo)] (M=Ni (), Cu (), with acbo=anthra-9,10-chinone-2,3-bis(oxamato) have been synthesized starting from symmetric diethyl N,N'-anthra-9,10-chinone-2,3-bis(oxamate) (, 2,3-acboH2Et2). The crystal structures of and have been determined, verifying…
Carbon Nitride (CNx) coating was reported to show a superlow friction coefficient when it slid against a Si3N4 ball in nitrogen gas at atmospheric pressure. This superlow friction phenomenon occurred after a number of sliding cycles, in the so-called running-in period, due to the nitrogen atom desorption from the topm…
LaCoO3 powders are studied because they exhibit interesting electrical, magnetic and catalytic properties. In this paper, new synthesized La2O3-CoO-SiO2 powders with different quantity of silica were prepared via solgel method in aqua media, starting from metal nitrates with different chelating agents. The relation be…
This paper reports the first effort to synthesize a new class of inorganic nanostructured materials consisting of alternating ultrathin layers of nanoclays and oxide ceramics. A novel solution‐based layer‐by‐layer (LBL) deposition technique was developed to prepare multilayers of hydrated Zr cations and nanoclays. Thi…
Crack features of resistance spot welded magnesium alloy joint and effects of welding parameters on susceptibility of the joint to hot cracking have been investigated. In the spot welded joints, solidification cracking in weld nugget and liquation cracking in heat-affected zone (HAZ) were often observed. The formation…
In the age of structural proteomics when protein structures are targeted on a genome-wide scale, the identification of proteins that are amenable to analysis using x-ray crystallography or NMR spectroscopy is the key to high throughput structure determination. NMR screening is a beneficial part of a structural proteom…
In order to establish the relationship between surface chemistry and wettability as a function of dew point, an attempt has been made to simulate the hot-dip galvanizing process with an ‘in-house’ built Liquid Zinc Spin Coater. Interstitial free (IF) steel was annealed at 820°C in N2-5%H2 gas atmospheres with dew poin…
有三种不同尺寸的 Fe3O4 nanoparticles (NP ) 的象 Peroxidase 一样催化性质，由化学一起沉淀和大音阶的第五音鈥揼e l 方法综合了，被紫外鈥搗i s 光谱分析调查。由把 Fe3O4 NP 与 11， 20，和 150 nm 的平均直径作比较，我们发现催化活动与减少的 nanoparticle 尺寸增加。用反应产品和底层的反应水流描绘 Fe3O4 NP 的催化活动的电气化学的方法也被开发。
Phase transformations that occur in the brazing alloy Ag70.5Cu26.5Ti3 are described. The liquid segregation paths and the liquid composition path are presented. The evolution of the liquid and the concentration of titanium in the liquid are plotted versus temperature. With increasing temperature the activity of titani…
The usage of polycrystalline diamond onto steel substrates for potential usage in cutting tools, plastic injection moulds and biomedical tools, would be of great importance. In this paper, a review of the different approaches used to improve coating adhesion has been presented. Before this, the major problems hinderin…
Water treeing is a phenomenon that is already known for more then 35 years and is one of the reasons for cable failures (polymeric cables) in the medium-voltage network. The final stage of water treeing is the formation of electrical trees on top of the water trees. Due to the fact that the moment of electrical tree i…
Transparent conducting thin films were deposited on quartz substrates using radio frequency (rf) magnetron sputtering at 20% oxygen partial pressure. In the visible region, the transmittance of Zn-doped thin films is relatively low, whereas the thin film has a high transmittance of about 80%. The electrical conductivi…
Stripline circulator theory and applications from the world's foremost authority. The stripline junction circulator is a unique three-port non-reciprocal microwave junction used to connect a single antenna to both a transmitter and a receiver. Its operation relies on the interaction between an electron spin in a suita…

Photoinduced Fe-to-bpy charge transfer in [{Cp(dppe)Fe}(mu-C[triple bond]CC[triple bond]N){Re(CO)(3)(bpy)}]PF(6) has been observed by ps-TRIR spectroscopy, supported by UV-Vis/IR spectroelectrochemistry and DFT calculations.
The alignment of mesochannels in a mesoporous silica film on a freshly cleaved mica surface, prepared by an evaporation-induced self-assembly process, is unexpectedly found to be unidirectional with the narrowest directional distribution.
Continuously-casted Mg-9Al-1Zn-1Ca (in mass%) alloy (Mg-Ca alloy) and Mg-9Al-1Zn alloys (Ca-free Mg alloy) were forged at 573 K and their mechanical properties were investigated by tension tests at ambient temperature and 573 K. The forged Mg-Ca alloy showed higher 0.2% proof stress than the forged Ca-free Mg alloy. T…
In the previous papers, the sintered Ti-6Al-2Sn-4Zr-2Mo alloy compacts showed higher tensile strength than the Ti-6Al-4V alloy compacts, and the strengthening of Ti-6Al-4V alloy compacts were available by addition of fine Mo powder because of fine microstructural modification. In this study, the metal injection moldin…
A novel method to produce multilayer films has been developed by layer-by-layer assembly of single-charged ions and a rigid polyampholyte containing unbalanced charges in each of its repeat units.
Effects of manganese oxide (MnO) addition on the densification of Al2O3 during sintering were studied. Although MnO is commonly used as a sintering aid for Al2O3, it has not been used as a sintering aid to produce transparent alumina. High-density Al2O3 doped with slight MnO (> 99.5%) was obtained using a conventional…
