A review was provided of the research progress of the inhibition mechanism of benzotriazole (BTA) as corrosion inhibitor for copper. The surface structure and composition as well as the corrosion inhibition type of protective films of BTA formed in acidic medium, nearly neutral medium and alkaline medium were highligh…
Catalytic reduction of NO by metallic iron mesh roll was experimentally studied in a horizontal ceramic tubular reactor.The NO reduction efficiency was tested in the temperature range of 300-1 100 ℃ in the atmospheres of CO,O2,CO2 and simulated flue gas respectively.The results show that metallic iron is very effectiv…
The construction and main constituent of the integument of Eriocheir sinensis were studied by the methods of histochemistry and atomic absorption methods.The results showed that the integument of E.sinensis was composed of four sub-layers from the exterior to the interior: an epicuticle,an exocuticle,an endocuticle,an…
In this paper, bile acids' retention parameter, R(M), obtained in normal phase thin-layer chromatography is determined as a function of the temperature (293-323 K). Analyzed bile acids belong to congeneric group with two oxygen atoms (OH or oxo groups) on the steroid core and congeneric group with three oxygen atoms.…
This chapter presents three contemporary applications of natural rubber. In the first application, natural rubber membranes with gold nanoparticles were placed in the culture medium and the physiological behaviour of Leishmania braziliensis promastigotes evaluated. The natural rubber membranes containing AuNPs decreas…
Using isothermal compression test and quantitative metallographic analysis,the deformation behavior and microstructure evolution of as-extruded aluminum alloy 7075 were studied within a temperature range of 250-450 ℃ and a strain rate range of 0.01-10s-1.The true stress—strain curves,average grain size,recrystallized…
ZnSnO3 one-dimensional (1D) strutures were synthesized by using an evaporation technique. The morphology, crystal structure, and enhanced sensing properties of the ZnSnO3 structures functionalized with Pd to CO gas at 300 degrees C were investigated. The diameters of the 1D structures ranged from a few hundreds to a f…
Ca-K codoped La0.64Ca0.25K0.11MnO3 nanocrystals with rhombohedral structure were synthesized in a molten KOH system at temperature as low as 500 ℃ in the atmosphere of Ar.The starting materials were MnO2,Ca(OH)2 and La(OH)3.Mn oxidation state and magnetic properties of La0.64Ca0.25K0.11MnO3 were discussed.XPS results…
To understand the effect of water-cut sheds on flashovers of contaminated hollow core insulators in heavy rain,we performed simulative experiments.Taking 5-meter-long hollow core porcelain insulators for examples,we experimentally simulated flashovers on the samples in heavy rain,and measured the characteristics of th…
In order to enhance the utilization of kenaf stems, chemical stabilities against hydrothermal reactions were compared between core parts and bast ribbons. With increasing the treatment temperature, hemicellulose fractions contained in the intercellular matrix regions were preferentially decomposed. This tendency was m…
This work reports the design and use of a laboratory-scale tribometer and a new developed tool-holder to reproduce the industrial polishing process for ceramic tiles in laboratory-scale. The mechanical conditions in a typical industrial polishing process were used to execute the tests in industrial-scale on a single p…
Both silicon wafers and thermally oxidized silicon wafers are diced into 14x14 mm2 pieces to fit the circular active area with 11 mm diameter used in voltammetry. 50 nm of tungsten is sputtered on both sides of the chips for edge coverage to have better electrical contact of back side and grown side. A catalyst layer…

Изучен протеолиз Pro-Gly-Pro-Leu, Pro-Gly-Pro-Gly и Pro-Gly-Pro в сравнении с Met-Glu-His-Phe-Pro-Gly-Pro (семакс). Показано, что все три пептида значительно более устойчивы к действию N-лейцинаминопептидазы (КФ 3.4.11.1, Sigma, Тип VI, 9.2 ед. акт./мг), а также ферментов назальной слизи, микросомальной фракции мозга…
Digital image processing has been utilised widely in manufacturing for accurate automated inspection. Image processing is one such technique that involves computer processing of pictures or images that have been converted to numerical form. This paper presents a critical review of the exhaustive work of digital image…
Conducting polymers are known to have significant electrical properties which can be improved by strong oxidizing power of oxidizing agents like V 2 O 5 . In the current study oxidative polymerization of the thiophene monomers was done to obtain Polythiophene for converting it into its composites with V 2 O 5 to study…
Nine years after the existence of resident Cardiac Stem Cells was first demonstrated, and despite the fact that we are right now evaluating the preliminary and promising results of the first phase I clinical trials, our understanding of the mechanisms responsible for cardiac regeneration is still partial and the abili…
Structural phase transitions of Li2MgSiO4 and Li2MgGeO4 at high temperature have been investigated by means of in situ high temperature powder XRD measurements. The monoclinic P21/n phase of Li2MgSiO4 shows a reversible phase transition to high temperature orthorhombic Pmnb phase due to the order-disorder of Mg and Li…
This paper presents development of an industrial motor with an amorphous winding core for large capacity applications. The motor is developed for establishing proper motor designs to apply amorphous cores to large capacity motors. The motor design and the test results of a trial motor are discussed in this paper. In t…
ホスホリルコリン(PC)基を含有する芳香族ジアミンモノマーを用い，可溶性芳香族ポリアミド，ポリアミド–エステルおよびポリウレタン–ウレアの合成を行った．ポリアミド–エステルおよびポリウレタン–ウレアでは，ソフトセグメントを形成するコモノマーとしてポリカーボネートジオールを用い共重合することで，溶媒キャスト法により自己支持性のある弾性フィルムを作製できPC基含有エラストマーが得られた．とくに，ポリウレタン–ウレアから作製したフィルムは，市販のポリカーボネートウレタンであるBionate®と類似した機械的性質を示し，PC基を導入してもポリウレタン特有の弾性を維持できることがわかった．さらに，得られたポリマーフィルムはタンパク質や血小板…
