This paper reviews the development of new material and surface technology in tribology and its contribution to energy efficiency. Two examples of the economic benefits, resulted from the optimum tribology in the transportation sector and the manufacturing industry are discussed. The new materials are proposed to modif…

The graft copolymer of natural rubber (NR) and 2-hydroxyethyl methacrylate (HEMA) was prepared by seeded emulsion polymerization using cumene hydroperoxide (CHP) and tetraethylene pentamine TEPA) as an initiator system. The structures of the copolymers were characterized by FT-IR and 1H-NMR spectroscopy techniques. Th…
The root mean square （RMS） roughness and surface scattering of Ag films，Y2O3-stabilized ZrO2 films，TiO2 films，and 1064 nm & 532 nm two-wavelength-reflection-reducing films are studied respectively by the total integrated scatter. Considering the preparation condition，growth process，material composition，and optical cha…
The nonlinear sensing property and electric mechanism of carbon humidity-sensitive membranes under investigation were manufactured by using hydroxyethyl cellulose （HEC）, carbon black （CB） and humidizer sorbitol. Microstructures examined by scanning electronic microscopy （SEM） show that, an effective carbon black elect…
Protein blotting, also known as Western blotting, refers to the transfer of proteins to an immobilizing membrane. The most widely used blotting method is the electrophoretic transfer of resolved proteins from a polyacrylamide gel to a nitrocellulose or polyvinylidene difluoride (PVDF) sheet and is often referred to as…
成核的吸附和散开。吸附地点，相应于为孤立的广告原子的势能表面(足) 的本地最小，在不同地点通过广告原子绑定精力的比较研究被识别。我们发现桥(siloxane ) 地点被喜欢甚于另外的吸附地点。在为进这个地点的氧插入的 0K 没有精力障碍。当在二个吸附地点之间跳时，广告原子不得不克服的散开精力障碍是计算的。硅石成核的前提被由于和附近的广告原子的相互作用计算氧原子绑定精力的修正调查。
For the practical use of improved interlaminar fracture toughness by interleaving carbon non-woven tissue (CNWT), intelaminar fracture toughnesses of CFRP laminates with CNWT having different weights were experimentally investigated. A suitable weight of interleaved CNWT in CFRP laminates was discussed with Mode I and…
Six fruit nutshells, namely: Thevetia nerrifolia, Hura crepitans, Hyphaene thebaica, Pentachlethra macrophyla, Tetracapidium conophorum and Cocos nucifera were carbonised, oxidized with atmospheric air and activated in CO2 at 840°C for 3 h. The iodine number range of active carbon (AC) was 822-1804 mg/g while BET surf…
Thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and impedance spectroscopy (IS) were used to examine the high-temperaure phase equilibria of KH2PO4 (KDP). The tested samples (named as KDP*) were prepared by heating KDP crystals up to 260°C. On subsequent heating the solid samples from room te…
The final rule for mine seals issued in 2008 increased the seal design strength and specified new requirements for the engineering and construction of mine seals. New seal designs must resist a design pressure-time curve, remain elastic to withstand repeat overpressures, have adequate anchorage to the surrounding stra…
In order to characterize and classify quantitatively the local topological structure of traditional fullerene graphs a new method has been developed. The concept is based on the introduction of a finite set of novel topological invarians called pentagon arm indices. The definition of pentagon arm indices is similar to…
Longitudinal-field muon spin rotation (LF-μSR) experiments in the two-dimensional geometrically-frustrated antiferromagnet NiGa2S4 reveal a number of features of spin freezing and dynamics in this system. Long-lived (correlation time 10-6 s at 2 K) disordered Ni spin freezing sets in abruptly below Tf = 8.5±0.5 K. At…
Uncertainty analysis aims at characterizing the errors associated with experiments and\n\npredictions of computer codes, in contradistinction with sensitivity analysis, which aims at\n\ndetermining the rate of change in the predictions of codes when one or more input parameters\n\nvaries within its range of interest.…
Finite element models are developed by using the explicit dynamic analysis nonlinear finite element procedure LS-DYNA,with simulation of the impact responses and failure modes of steel frame columns,to analyze failure modes of steel frame columns and influencing factors under three kinds of blast loading.The results s…
Electric field of composite insulator can be reduced by grading rings,the position and dimension of grading rings are main factors for distribution of electric field.The optimal model of grading rings is a kind of nonlinear relationship between electric field and parameters with constraint condition.Genetic algorithm(…
In view that the stator and rotor resultant magneto-motive forces (MMF) of the fifteen-phase induction motor under non-sinusoidal supply is of non-sinusoidal distribution, the distributed magnetic circuit method is put forward to perform magnetic circuit calculation and the magnetizing reactances are deduced. Based on…
The liquefying and melting processes of the binary mixed system consisting of a new type of high energy density materials 3,4-dinitrofurazanfuroxan(DNTF) and pentaerythritol(PETN) were studied by pressure differential scanning calorimetry(PDSC).On the basis of PDSC characteristic values of DNTF/PETN systems with vario…
In this study, we attempted to manufacture wood-based products of arbitrary shapes and high strengths by allowing cryptomeria powders to flow and harden in a metal mold without using a binder. Experimental results show that wood powders have good liquidity owing to the maintenance of their moisture using the metal mol…
