The technology parameters of P-RC APMP process of the triploid of populus tomentosa and the comparison of P-RC APMP with one and two stage of pretreatment were investigated in this paper. The results showed that in the chemical pretreatment the charge of NaOH and H2O2 were the main factors that affected the pulp qualities. The charge of NaOH, especially in the first stage of chemical pretreatment, was related to pulp strength. The charge of H2O2 contributed much to brightness of the resultant pulp. In addition, the ratio of NaOH to H2O2 and the distribution of chemicals in the first and second stage of impregnation also affected the pulp qualities. The comparison of one-stage P-RC APMP pulp and two-stage P-RC APMP pulp illustrated that the two-stage pulp had better brightness and breaking length, lower light scatting coefficient and opacity

痛风是尿酸盐沉积引起的一种代谢性疾病,可导致关节畸形、痛风性肾病及心血管疾病等。近年来,痛风患病率逐渐上升且呈年轻化趋势。对可疑患者进行关节穿刺并在显微镜下观察到单钠尿酸盐(monosodiumurate,MSU)晶体是诊断痛风的金标准,然而,其是有创操作,易造成出血、感染等并发症且假阴性率较高。影像技术的发展,使无创检测微小MSU晶体及痛风诊治关口前移变得可行,在亚临床期即可诊断痛风,避免相关并发症如关节功能丧失、肾功能不全的发生。故本文主要对痛风性关节炎在影像学的典型表现进行综述,以达到提高其诊断正确率的目的。

Nano Research 2016年第10期9卷 2875-2888页

作者： Feng zhan Tianyu Liu guihua Hou Tianyi Kou Lu Yue Rongfeng Guan Yat Li Key Laboratory for Advanced Technology in Environmental Protection of Jiangsu Province Yancheng Institute of Technology Yancheng 224051 China Department of Chemistry and Biochemistry University of California Santa Cruz 1156 High Street Santa Cruz CA 95064 USA

The growing demand for portable electronic devices means that lightweight power sources are increasingly sought after. Electric double layer capacitors （EDLCs） are promising candidates for use in lightweight power sources due to their high power densities and outstanding charge/discharge cycling stabilities. Three-dimensional （3D） self-supporting carbon-based materials have been extensively studied for use in lightweight EDLCs. Yet, a major challenge for 3D carbon electrodes is the limited ion diffusion rate in their internal spaces. To address this limitation, hierarchically porous 3D structures that provide additional channels for internal ion diffusion have been proposed. Herein, we report a new chemical method for the synthesis of an ultralight （9.92 mg/cm3） 3D porous carbon foam （PCF） involving carbonization of a glutaraldehyde- cross-linked chitosan aerogel in the presence of potassium carbonate. Electron microscopy images reveal that the carbon foam is an interconnected network of carbon sheets containing uniformly dispersed macropores. In addition, Brunauer-Emmett-Teller measurements confirm the hierarchically porous structure. Electrochemical data show that the PCF electrode can achieve an outstanding gravimetric capacitance of 246.5 F/g at a current density of 0.5 A/g, and a remarkable capacity retention of 67.5% was observed when the current density was increased from 0.5 to 100A/g. A quasi-solid-state symmetric supercapacitor was fabricated via assembly of two pieces of the new PCF and was found to deliver an ultra-high power density of 25 kW/kg at an energy density of 2.8 Wh/kg. This study demonstrates the synthesis of an ultralight and hierarchically porous carbon foam with high capacitive performance.
