导电水凝胶是具有独特导电性、力学稳定性、较高柔软性的三维网络结构的物质,具有广阔的应用前景。制备具有特殊功能性导电水凝胶材料的研究吸引了科研工作者广泛的关注,其制备策略主要是聚合物水凝胶与导电物质交联混合。为了提高其导电性和机械形变,主要策略是设计和制备导电纳米材料(如碳纳米管、石墨烯、金属纳米和液态金属等)填充和导电高分子(如聚苯胺(PANI)、聚吡咯(PPy)、聚噻吩(PYh)等)基导电水凝胶。文章综述了聚电解质、酸掺杂、无机物填充、导电高分子基四类导电水凝胶的研究进展;为解决导电水凝胶导电性、力学稳定性、耐极端温度和生物相容性的问题,本文总结了导电水凝胶的制备策略,最后总结了导电水凝胶面临的挑战。

The downward shortwave radiation(DSR) is an important part of the Earth's energy balance, driving Earth's system's energy, water, and carbon cycles. Due to the harsh Antarctic environment, the accuracy of DSR derived from satellite and reanalysis has not been systematically evaluated over the transect of Zhongshan station to Dome A, East ***, this study aims to evaluate DSR reanalysis products(ERA5-Land, ERA5, MERRA-2) and satellite products(CERES and ICDR) in this area. The results indicate that DSR exhibits obvious monthly and seasonal variations, with higher values in summer than in winter. The ERA5-Land(ICDR) DSR product demonstrated the highest(lowest) accuracy,as evidenced by a correlation coefficient of 0.988(0.918), a root-mean-square error of 23.919(69.383) W m^(–2), a mean bias of –1.667(–28.223) W m^(–2) and a mean absolute error of 13.37(58.99) W m^(–2). The RMSE values for the ERA5-Land reanalysis product at seven stations, namely Zhongshan, Panda 100, Panda 300, Panda 400, Taishan, Panda 1100, and Kunlun, were 30.938, 29.447, 34.507, 29.110, 20.339, 17.267, and 14.700 W m^(-2), respectively;with corresponding bias values of 9.887, –12.159, –19.181, –15.519, –8.118, 6.297, and 3.482 W m^(–2). Regarding seasonality, ERA5-Land, ERA5,and MERRA-2 reanalysis products demonstrate higher accuracies during spring and summer, while ICDR products are least accurate in autumn. Cloud cover, water vapor, total ozone, and severe weather are the main factors affecting DSR. The error of DSR products is greatest in coastal areas(particularly at the Zhongshan station) and decreases towards the inland areas of Antarctica.

哥本哈根气候大会尽管没有达成具有法律约束力的协议,但是它却对世界经济的发展产生了深远影响,低碳经济理念成为全球共识。在今后相当长的时期,世界经济发展呈现如下趋势:发达国家和地区将实现社会发展模式转型,新的贸易投资机会将被催生,碳减排国际合作潜力巨大,碳关税可能成为影响国际贸易的新壁垒,战略性新兴产业国际竞争趋于激烈等。如此发展趋势将对我国经济发展提出新的挑战,集中表现在减排压力、出口压力、制造业发展压力和开放经济战略实施压力等,因此需要正视后哥本哈根时代的世界经济形势,把握低碳时代脉搏,勇于面对挑战,从国际国内两个层面采取对策推动我国经济社会向更高层次发展。

Electroreduction of nitrate(NO_(3)-)to ammonia(NH_(3))is an environmentally friendly route for NH_(3)production,serving as an appealing alternative to the Haber-Bosch ***,various noble metal-based electrocatalysts have been reported for electroreduction of NO_(3)-.However,the application of pure metal electrocatalysts is still limited by unsatisfactory performance,owing to the weak adsorption of nitrogen-containing intermediates on the surface of pure metal *** this work,we report thiol ligand-modified Au nanoparticles as the effective electrocatalysts toward electroreduction of NO_(3)-.Specifically,three mercaptobenzoic acid(MBA)isomers,thiosalicylic acid(ortho-MBA),3-mercaptobenzoic acid(meta-MBA),and 4-mercaptobenzoic acid(para-MBA),were employed to modify the surface of the Au *** the NO_(3)-electroreduction,para-MBA modified Au(denoted as para-Au/C)displayed the highest catalytic activity among these Au-based ***-1.0 V versus reversible hydrogen electrode(vs RHE),para-Au/C exhibited a partial current density for NH_(3)of 472.2 mA cm^(-2),which was 1.7 times that of the pristine Au ***,the Faradaic efficiency(FE)for NH_(3)reached 98.7%at-1.0 V vs RHE for para-Au/*** modification of para-MBA significantly improved the intrinsic activity of the Au/C catalyst,thus accelerating the kinetics of NO_(3)-reduction and giving rise to a high NH_(3)yield rate of para-Au/C.
