The UNS S31035 austenitic stainless steel grade is a newly developed advanced heat resistant material for use in coal fired boilers at material temperatures up to about 700°C. This new grade has good resistance to oxidation and hot corrosion, and shows higher creep rupture strength than other austenitic stainless stee…

A sensitive and selective electrochemical method for simultaneous determination of ascorbic acid (AA), dopamine (DA), and uric acid (UA) using an electropolymerized bromothymol blue (BTB)-modified glassy carbon electrode (GCE) was developed. The electrochemically synthesized film was investigated using electrochemical…
Sputter-etching was applied to type 303, 304, 430 and 420 stainless steels to form conical or ring-shaped protrusions on the surface, and the tensile test of the substrate with protrusions, the press and scratch tests of protrusions were carried out. The tensile test shows that the conical protrusion is ductile, and t…
The aim of this study is to demonstrate a method to control interactions between two surfaces by the use of a responsive solution. This was done by performing AFM-based force measurements between two silica surfaces immersed in an aqueous solution of thermo-responsive Pluronics P85 block copolymers. For this system we…
We report nanostructure electrodes for methanol electrooxidation by means of the co-sputtering deposition method. The Pt-WC-WO(3) three-phase electrode has higher I(f)/I(b) and oxidation current density i.e. improved electrocatalytic activity in comparison with those of pure Pt and two-phase electrodes because of both…
The development of deployable small modular reactors (SMRs) will provide the United States with another economically viable energy option, diversify the available nuclear power alternatives for the country, and enhance U.S. economic competitiveness by ensuring a domestic capability to supply demonstrated reactor techn…
The mechanical behaviour of duplex phases produced in a medium carbon low alloy steel with potentials for use as machine body parts and vehicle panels, has been investigated. A representative composition of the steel (C: 0.3; Si: 0.28; Mn: 0.97; Cr: 0.15) was utilized to produce ferrite -martensite duplex phases of va…
A simple, microwave-assisted, strategy for producing Au/Ag concentrated sols by glucose reduction in water was developed. Ag-Au bimetallic nanoparticles stabilized by polyvinylpyrrolidone (PVP) were characterized and their catalytic activity was studied in the reduction of 4-nitrophenol with NaBH4 as a probe reaction.…
T-91 steel sample followed somewhat linear rate of oxidation while T-22 sample followed the parabolic rate law of oxidation. X-ray diffraction (XRD) and scanning electron microscopy/energy dispersive X-ray (SEM/EDAX) techniques were used to characterise the oxide scales. T-91 steel was found to be more corrosion resis…
We have developed a semi-empirical model to relate the tensile energy absorption (TEA) of paper sheets formed from high-consistency refined pulp to pulp properties, including water retention value (WRV), fibre length, and fibre curl. TEA is shown to be related to the normalized stretch (ratio of stretch to tensile str…
在铁和钢工业的当前的精力保存和排出物减小策略是 reviewed.Since 铸造工业是精力消费和污染排放(特别 CO2 )的主要来源之一，问题有关节省精力并且排放减小被政府提起了，来自整个世界的 industry.Specialists 在铁和钢工业在精力保存和排出物减小在潜力上执行了多维的分析和评估，并且求婚
Ostracod assemblages from the Upper Permian and lowermost Triassic of Northwest Iran comprise 35 species including the new species Kirkbya jolfaensis, Cavellina jolfaensis, Bairdia zaliensis and Bairdiacypris zaliensis. The Upper Permian ostracods show a strong endemic character. A number of the endemic species are co…
Structure determination of multidomain proteins or protein–membrane complexes is one of the most challenging tasks in modern structural biology. High-resolution techniques, like NMR or X-ray crystallography, are limited to molecules of moderate size or those that can be crystallized easily. Both methods encounter seri…
One of the main objects with which the Geological Society of India was started, more than fifty years ago, was to promote the cause of advanced study in all branches of the geology of India.This object was sought to be served by the publication of a Journal including the best work in geology and related fields.Early i…
In order to establish the rolling process parameters of grade-2 commercially pure titanium(CP-Ti),it is necessary to understand the transformation mechanism and mechanical properties of this material.The β→α transformation kinetics of the grade-2 CP-Ti during continuous cooling was measured and its hot compression beh…
Single crystals of Sc2(TO4)3 with T = Mo and W were synthesized from Sc2O3, MoO3, and WO3 at 1223 K in NaCl / KCl as solvent. Both structures were refined from X-ray diffractometer data: Pbcn, a = 1325.1(1), b = 954.9(1), c = 964.4(1) pm, wR2 = 0.0425, 2097 F2, 79 variables for Sc2(MoO4)3 and a = 1332.9(9), b = 959.4(…
The performance of current sidewalls made of carbon and silicon based materials relies on the existence of a frozen electrolyte layer. The development of the Hall-Heroult cell technologies such as inert anodes and wettable cathodes, call for new sidewall materials since the frozen ledge may no longer be applicable. Ni…
Solid dispersions in water-soluble carriers have attracted considerable interest as a means of improving the dissolution rate and hence possibly bioavailability, of a range of hydrophobic drugs. The poor solubility of valsartan leads to poor dissolution and hence variation in bioavailability. The purpose of the invest…
Glass is relatively durable in acidic to neutral solutions. Durability is often a desirable property, but in some applications some surface dissolution and reactivity are desired, e.g. bioactive glasses. In this work we compare the suitability of three methods; modified ISO 719, dynamic water, and static TRIS-buffered…
