Thermodynamic Studies on The Interaction of nickel With Human Serum Albumin

生物化学与生物物理进展 2003年第5期30卷 732-737页

The interaction of human serum albumin with divalent nickel ion was studied by equilibrium dialysis, isothermal titration calorimetry (ITC), differential scanning calorimetry (DSC) and circular dichroism (CD) in 30 mmol/L Tris buffer , pH=7 0. There is a set of 8 identical binding sites for nickel binding on the protein at two temperatures of 300 K and 310 K. The cooperativity in the binding is observed at 310 K. The Hill coefficients at 300 K and 310 K are 0 97 and 1 25, respectively. The interaction between nickel ions and HSA is exothermic. A value of -36 5 kJ for enthalpy of interaction ( 1∶1 stoichiometry) was obtained. The secondary structure of HSA dose not show any change during the binding nickel ions process. However, the tertiary structure of the protein changes, which shows the existence of two natives like states.

亚洲视野中的秦兵马俑

古代墓葬美术研究 2011年第1期 23-40页

作者：倪克鲁陈亮伦敦大学亚非学院

…for all our knowledge of the way they were originally finished,we shrink from admitting that their prime effect must have been sheer realism.[1]1974年秦始皇陵墓陶俑、陶马等的发现激起学者持久的兴趣,此后,大量展览图录、专著和论文不断出版和发表。研究课题涉及陶俑在帝陵中的象征意义、宗教功能、陶俑作为写实性人物形象乃至肖像的风格特征、陶俑的制作方式及其原有着色,以及陶俑与考古学和历史学的关系等诸多方面。然而,与兵马俑以及在其他陪葬坑中所发现的文吏俑、乐舞俑、百戏俑相关的一个重要现象,至今却鲜有人论及,那就是,在这些陶俑制造之前的数个世纪,即东周时期,人物雕像很少放置在墓葬中,也绝少在公共场所使用。

Up to this date,researchers are still facing difficulties to expand the technology of direct methanol fuel cells(DMfCs) because of the high overpotential required to oxidize the methanol and its relatively poor performance due to CO poisoning of the leading-high cost anode *** line with this,we have successfully modified the morphological structure and composition of low cost cobalt based-metal oxides,MCo_2O_4(M = Zn and Ni),with the simple and noble use of polyvinyl pyrrolidone(PVP) as growth modifier and surface stabilizer during the synthesis of nanoparticles in our previous reports,which shown high electrocatalytic activity and strong *** to the good performance of our PVP modified MCo_2O_4 towards pseudocapacitor and oxygen evolution reaction applications,we decided to extend our research study to methanol oxidation ***,PVP modified Ni Co_2O_4 electrode directly grown on nickel foam substrate via a simple hydrothermal process exhibited better performance compared with PVP modified ZnCo_2O_4 and NiCo_2O_4 without *** had obtained a remarkably low onset potential of 0.285 V and high current density of 280 m A cm^(-2),and shown great stability and high poison tolerance during a continuous CV cycling and Chronoamperometry test,which attained high efficiency of 86.86%and 98.52%,*** positive results of PVP modified Ni Co_2O_4 electrode towards MOR might be attributed to its hierarchical 3 D nanostructures with highly mesoporous surface and large surface area which may have provided numerous electroactive sites,and the exceptional corrosion stability of Ni Co_2O_4 electrode in alkaline solution.

nickel phthalocyanine(Ni Pc) film was deposited onto the surface of flexible conductive glass by rubbing-in technology and used to fabricate devices based on ITO/Ni Pc/CNT/rubber structure. The I–V characteristics of the devices were investigated under different uniaxial pressures of 200, 280, and 480 gf/cm^(2), applied perpendicular to the surface of the Ni Pc film. Results showed that the nonlinearity coefficients of the I–V curves are in the range of 2 to 3, which was found to be decreased with the increase of the pressure. The rectification ratio of the devices was estimated to be varied from 1.5 to 3 based on the applied pressure. Concluding, the resistance of the active layers was decreased with the increase of both pressure and voltage. We believe that using the rubbing-in technology under sufficient applied pressure it is possible to utilize Ni Pc for the development of various electronic devices such as diodes, nonlinear resistors, and sensors.

The Effect of NiAl Coatings on Oxidation Behavior of AISI 403 Stainless Steel

引用

材料热处理学报 2004年第05B期25卷 666-670页

作者： M. Ebrahimian f. Ashrafizadeh Iranian Surface Research & Engineering Centre Isfahan Science & Technology Town Isfahan IranDepartment of Materials Engineering Isfahan University of Technology Isfahan Iran

This paper reports the oxidation behavior of stainless steel type 403 as a substrate material with and without NiAl coating. Evaluation of oxidation resistance was performed on uncoated and coated specimens at 850 and 1050°C. A commercial diffusion process was used for the formation of NiAl intermetallic coatings on the specimens. Before aluminizing, a layer of nickel, about 40 um, was deposited on specimens by electroplating. Various techniques including SEM, EDAX, optical microscopy and micro-hardness testing were employed to investigate the coatings before and after oxidation tests. nickel-aluminides produced by two stage; plating-aluminizing, treatment with NiAl on the surface increased the performance of stainless steel samples significantly.

Effects of Silicon Nanoparticles on the Transient Liquid Phase Bonding of 304 Stainless Steel

Journal of Materials Science & Technology 2014年第3期30卷 259-262页

Transient liquid phase （TLP） bonding of 304 stainless steel with nickel based filler metal, BNi-9, was performed to study the influence of silicon nanoparticles （NPs） on the mechanical and structural properties of the bonding area. It was found that silicon NPs act as a melting point depressant in the brazing process; the formation of silicon TLP induces the dissolution of elements of the metal filler and promotes a uniform distribution in the bonding area. Silicon NPs induce the development of smaller eutectic structures in the melting zone; it has been related to microhardness measurements, which are lower when the silicon NPs are used in the brazing process.
