N-doped carbons were fabricated from zeolite-templated carbon via modification with melamine and mild KOH activation. The N-doping treatment and KOH activation slightly lowered the surface areas of pristine zeolite-templated carbon; nonetheless, N-doped carbons with a lower surface area exhibited much higher capacitance and cycling stability as fabricated into symmetric supercapacitor. Significantly, N-doped carbon obtained at 700°C showed a capacitance of 45.7 F/g at 0.1 A/g and 42.0 F/g at 10 A/g for the fabricated supercapacitor with 6 M KOH electrolyte, with 92% retention of initial capacitance as current density increased up to 100-fold. This performance was attributed to the dual contribution of electric double-layer capacitance and pseudo-capacitance. The assembled supercapacitor also exhibited excellent cycling stability, with 91% capacitance retention at 10 A/g after 10000 cycles.

Background The aim of this study was to investigate the potential relationship between the dynamic expression of Toll-like receptor 2 and 4 （TLR2/4） in peripheral blood mononuclear cells as well as changes in serum concentration of inflammatory factors and acute lung injury （ALl） in patients after orthotopic liver transplantation （OLT）. Methods The peripheral blood samples of 27 patients （23 men and 4 women with ASA Ⅲ to Ⅳ） who received OLT were collected for measurement of TLR2/4 at T1 （after induction of anesthesia）, T2 （25 minutes after anhepatic phase）, T3 （3 hours after graft reperfusion） and T4 （24 hours after graft reperfusion）. The expression of TLR2/4 in mononuclear cells was measured by flow cytometry. The serum concentrations of tumor necrosis factor （TNF）-α, interleukin （IL）-1β and IL-8 were measured by enzyme-linked immunosorbent assay （ELISA）. Twenty-seven patients were assigned to ALl group （n=-9） and non-ALl group （n=-18） according to the diagnostic criteria of ALl. The expression of TLR2/4 in the ALl group or non-ALl group was analyzed. Results Compared to the non-ALl group, the volumes of blood loss, ascites, total output and transfused red blood cells were higher in the ALl group, and the anhepatic phase lasted longer （P 〈0.05, P 〈0.01）. The expression of TLR2/4 in mononuclear cells increased significantly at T3 and T4, and serum concentrations of TNF-α, IL-1β and IL-8 increased significantly too. There was no significant difference in Child-Turcotte-Pugh （CTP） scores between the ALl group and non-ALl group （P 〉0.05）. The expression of TLR2/4 in mononuclear cells increased significantly at T3 and T4 in the ALl group （P 〈0.05, P〈0.01）. A positive correlation was noted between the expression of TLR4 in mononuclear cells and the serum concentrations of TNF-α, IL-1β （P=0.041, P=0.046） in the ALl group. In the non-ALl group, statistical results showed that the expression level of TLR2/4 in mononuclear cells was not significantly different during the pe

为了研究背景噪声对长江地学气枪主动源实验激发效果的影响,收集了240个台站激发前72小时的背景噪声数据及20个定点激发的叠加结果进行实验分析.先剔除异常台站,按照国标将台网噪声水平划分为高、中、低3个等级进行评估,从而研究气枪波形信噪比与台站背景噪声的关系.结果表明:(1)台站接收能力与背景噪声水平密切相关;(2)气枪信号的信噪比在一定范围内受背景噪声的影响大于距离衰减的影响;(3)长江马鞍山—安庆流域段不同定点激发的场地条件基本一致;(4)随气枪信号叠加次数的增加,低噪台站的信噪比增长速度快于中、高噪台站,若想获得同样的叠加效果,高噪台站需要的叠加次数远大于低噪台站.
