BACKGROUND: China has the largest potential market for organ transplants in the world, but it has not yet established brain death and organ transplant laws. We aimed to investigate the attitudes and suggestions of doctors, pharmacists, and civil servants concerning brain death, organ transplantation, and their respective legislation. METHODS: A questionnaire with 10 sections and 44 questions was designed and distributed. The effective questionnaire data were then recorded and checked for descriptive analysis. RESULTS: In 1400 questionnaires distributed, 1063 were responded and 969 of them were valid and analyzed. The respondents showed an incomplete understanding of brain death and organ transplantation laws. Seventy-four percent of the respondents recognized and accepted the standard of brain death. They agreed that legislation should be involved in the removal of organs for transplantation, the future use of organs, and insurance and compensation for the donor for possible health risks induced by organ removal. Of the 969 respondents, 92% considered it necessary to have legislation in brain death and organ transplantation, and 61% thought that it is time to legislate. CONCLUSIONS: Legislation for brain death and organ transplantation is urgent and timely in China. The laws must include the respective rights and obligations of patients, close relatives, and medical institutions. Educating the public about brain death and organ transplantation should also be encouraged in a variety of ways.

Catalyst–support interaction plays a crucial role in improving the catalytic activity of oxygen evolution reaction(OER).Here we modulate the catalyst–support interaction in polyaniline-supported Ni_(3)Fe oxide(Ni_(3)Fe oxide/PANI)with a robust hetero-interface,which significantly improves oxygen evolution activities with an overpotential of 270 mV at 10 mA cm^(-2)and specific activity of 2.08 mA cm_(ECSA)^(-2)at overpotential of 300 mV,3.84-fold that of Ni_(3)Fe *** is revealed that the catalyst–support interaction between Ni_(3)Fe oxide and PANI support enhances the Ni–O covalency via the interfacial Ni–N bond,thus promoting the charge and mass transfer on Ni_(3)Fe *** the excellent activity and stability,rechargeable Zn-air batteries with optimum Ni_(3)Fe oxide/PANI are assembled,delivering a low charge voltage of 1.95 V to cycle for 400 h at 10 mA cm^(-2).The regulation of the effect of catalyst–support interaction on catalytic activity provides new possibilities for the future design of highly efficient OER catalysts.

Effects of nitrogen application on beetle communities in tea plantations

Insect Science 2009年第2期16卷 185-192页

作者： shao-Bo Chen Zhi-Juan Wei Zhao-Hua Zeng Li-lin Chen Hui-Tao Chen Min-Sheng you Institute of Appfied Ecology Fujian Agriculture and Forestry University Fuzhou China

In contrast to grassland and forest ecosystems, little is known about insect response to nitrogen deposition in agricultural ecosystems. This study was carried out to investigate the effects of short-term （1-2 years） nitrogen application （0, 172.5, 345.0, 690.0, and 1035.0 kg · N ha^-1 · y^-1） on beetle communities in tea plantations. A collection of 34 families, 89 species of beetles, was obtained from a tea plantation in Wuyishan, China. Among them, herbivores, predators and detritivores had 52, 29, and eight species, respectively. Species richness, effective diversity and abundance （measured as the number of individuals and insect biomass） of the beetle community were not significantly related to the rate of nitrogen application. However, nitrogen application changed the species distribution and weakly increased the evenness of species distribution, while this did not significantly change the species evenness. Species richness and abundance of herbivores and predators were not significantly related to the rate of nitrogen application. However, there were some variations in trophic responses to nitrogen. Species richness and abundance of detritivores increased with increasing nitrogen application.

Magnesium-related solid bases have long been considered catalysts with weak or medium *** we report the fabrication of Mg single-atom catalysts with superbasicity for the first time.A sublimation-migration-anchoring strategy is employed,in which the Mg net is sublimated,transported by Ar,and trapped by defective graphene(producing Mg_(1)/G).Simulated and experimental results demonstrate that Mg single atoms are anchored on graphene in tetra-coordination,and Mg single atoms cooperating with C atoms give superbasicity,which differs from conventional alkali/alkaline earth metal oxides with basicity originating from O *** new solid base is highly active in the synthesis of dimethyl carbonate through transesterification of ethylene carbonate with methanol,which is usually catalyzed by strong *** turnover frequency value reaches 99.6 h^(-1) on Mg_(1)/G,which is much higher than that of traditional Mg-related counterparts(1.0–5.6 h^(-1))and even superior to that of typical Na and K-related solid superbases(29.8–36.2 h^(-1))under similar conditions.

Exfoliation corrosion of extruded Mg-Li-Ca alloy

Journal of Materials Science & Technology 2018年第9期34卷 1550-1557页

作者： Zi-you Ding Lan-Yue Cui Rong-Chang Zeng Yan-Bin Zhao shao-Kang Guan Dao-Kui Xu Cun-Guo lin College of Materials Science and Engineering Shandong University of Science and Technology Qingdao 266590 China School of Materials Science and Engineering Zhengzhou University Zhengzhou 450002 China CAS Key Laboratory of Nuclear Materials and Safety Assessment Institute of Metal Research Chinese Academy of Sciences Shenyang 110016 China Science and Technology on Marine Corrosion and Protection Laboratory Qingdao 266071 China Qingdao Branch of Luoyang Ship Material Research Institute Qingdao 266101 China

Exfoliation on as-extruded Mg-1 Li-1 Ca magnesium alloy was investigated after an immersion in 3.5 wt%NaCl aqueous solution for 90, 120 and 150 days through optical microscope, digital camera, scanning electron microscope, electrochemical workstation, scanning Kalvin probe, X-ray diffraction and Fourier transform infrared spectroscope. The results demonstrated that exfoliation corrosion occurred on extruded Mg-1 Li-1 Ca alloy due to elongated microstructure parallel to surface, and delamination of lamellar structure resulted from galvanic effect and wedge effect. Skin layer with fine grains exhibited better corrosion resistance, whereas the interior with coarse grains and the intermetallic compound,Mg2 Ca particles existing in a fibrous structure, dispersed along grain boundaries and extrusion direction in a line. Furthermore, galvanic effect between Mg2 Ca particles and their neighboring a-Mg matrix facilitated dissolution of Mg2 Ca particles and a-Mg matrix; wedge effect was caused by formation of corrosion products. Exfoliation corrosion of extruded Mg-Li-Ca alloys might be a synergic effect of pitting corrosion,filiform corrosion, intergranular corrosion and stress corrosion. Finally, exfoliation corrosion mechanism was proposed.
