Forecasting conductivities of LiBOB-EC/DEC electrolytes by the mass triangle modelJia-yuan Huang, Bi-tao Yu, Fu-shen Li, and Wei-hua Qiu School of Materials Science and Engineering, University...) electrolytes at 25°C and 50°C were studied. The electrolyte component with the highest conductivity at each temperature was obtained through changing the concentration of LiBOB and the ratio of EC/DEC......
MPP powder was investigated. The results show that for aluminum dust cloud with mass concentration of 375 g/m3, when MPP powder, MCA powder and ABC powder mass concentrations are 70.31, 93.75...; dust mass concentration 铝粉在油漆,油墨,颜料和焰火等工业生产领域得到广泛应用,当铝粉与空气形成爆炸性混合物后,就是一种潜在危险源.铝粉尘云点火能量低,燃烧速度快,可释放出大量能量,在一定条件下还会形成二次爆炸[1-3].铝粉爆炸防控是铝粉制造生产行业的重点研究方向,目标是把铝粉爆炸控制在初始阶段,缩小伤害范围和降低事故严重程度.国内外学者对此开展了相关研究,其中,ZHANG......
with the extract of leaves of MT using mass loss and electrochemical techniques. Parameters, such as concentration of the inhibitor, concentration of the acid, temperature and concentration of halide ions, were... the concentration of the acid as constant in the reaction system. Distilled water and analar grade chemicals were used for the study. 2.2 Mass loss method The pre-cleaned and pre-weighed Al specimens......
deteriorations in the bodies of slate. The experiments also approve that the deterioration degree of dry and wet action of slate is obviously greater than those of freeze-thaw-dry and wet alternating action and freeze-thaw action. Key words: slate; degradation; freeze-thaw action; dry-wet action; alternation action 板岩等低级变质岩常出露于白龙江流域等构造交互地区.该地区处于秦岭褶皱系南缘,松潘-甘孜褶皱系东侧,受区域构造地质背景及其主干断裂带的控制,新构造运动显著,造山活动强烈[1......
Antibacterial Action of Chemically Synthesized and Laser Generated Silver Nanoparticles against Human Pathogenic BacteriaJawad Nazir2,Syeda Ammara1,32. Department of Microbiology, University... synthesized chemically and by laser ablation, employed for in vitro antibacterial action against human pathogenic bacterium. Their formation was evidenced by UV-visible spectrophotometer; particle size......
while the permeate flux decreases. The composite membrane shows more than 90% oil rejection within the initial oil concentration range from 0.05% to 0.50% (mass fraction) at TMP of 0.30 MPa. The fouling... of transmembrane pressure(TMP), cross flow velocity, feed concentration on membrane performance were investigated, and ultrasonic cleaning of the fouled membrane was also investigated. The results show......
that as the mass concentration of CPB increases from 70% to 78%, the porosity, the average pore area and the number of pores drop overall, leading to a decline in the pores opening degree and enhancing the mechanical characteristics. As the mass concentration of CPB increases, the trend of fractal dimension, probability entropy and roundness is reduced, constant and increased, which can result......

Nanchang... Academy of Sciences摘 要:A new insight into the promotion action of Co2+on both particle and metal deposition in Ni-diamond composite electrodeposition system......
, resulting in the presence of many holes, fissures and joints in the rock mass. These discontinuities develop under the action of a load and make the mechanical properties and failure forms of the rock... the action of pressure, the wing cracks first initiate at the tips of the pre-flaw and have an angle of 75°-90° with the flaw because of the stress concentration and then propagate steadily along the loading......
Feasibility of developing composite action between concrete and cold-formed steel beamS. O. Bamaga, M. Md. Tahir, T. C. Tan, S. Mohammad, N. Yahya, A. L. Saleh, M. Mustaffar, M. H. Osman, A. B... constructed from sheets or coils using cold rolling, press brake or bending brake method. These structures are extensively employed in building construction industry due to their light mass, ductility......
