System, Features and Inspiration of Australia's Scientific Research Management

澳大利亚科研管理由政府统筹,立法完备、体制健全、程序公开,强调以绩效评估及审计等方式对科研经费开展预防为主的监管,科研产出效率高。研究借鉴澳大利亚的科研经费监管做法,在我国形成统一的制度和诚信立法、明确监督机构职责、加强科研评估和审计,对于提高我国科研经费使用的效率和效益,有着十分重要的现实意义。Australia's scientific research management is planned as a whole by the government, and has a perfect legislation, sound system, the open process.Regulation bases on performance evaluation and audit for prevention and bring out high-quality research output.Learning from Australia's research funding regulatory practices, we can form a unified system and integrated legislation in China, and determine responsibilities of supervision institutions, strengthen scientific research evaluation and auditing.This has practical significance in improving efficiency and effectiveness of scientific research management in China

Heat transfer performance of twisted-tube dry-expansion evaporator

对螺旋扁管干式蒸发器(TDE)和常规折流板干式蒸发器(BDE)的传热性能进行实验研究。研究了蒸发温度(Te)、冷凝温度(Tc)、管外壳程流体Reynolds数(Reo)和热通量(qi)对传热性能的影响。研究表明,随着Te、Reo和qi的增大,TDE和BDE的传热性能均提高。随着Tc的增大,TDE和BDE的传热性能降低。对装配TDE和BDE的风冷热泵分别进行了测试,测试表明,在相同制冷工况下,TDE的总传热系数比BDE提高了36.3%,风冷热泵的制冷性能系数(COP)相应地提高了6.0%；在相同制热工况下,TDE的总传热系数比BDE提高了41.7%,风冷热泵的制热COP值相应地提高了15.8%；说明TDE可应用于风冷热泵,且其性能优于BDE

Effects of Graphene on Electrochemical Behaviors of Ni(OH)2 as Supercapacitor Material

研究了氧化缺陷石墨烯对Ni(OH)2电化学性能的增强作用。实验上，由恒电位沉积法在石墨烯基底上制备Ni(OH)2纳米粒子/石墨烯复合材料。TEM观察和电化学测试表明，Ni(OH)2纳米粒子均匀地分散在石墨烯基底上，其粒径为5.0±0.5 nm，体系的质量比电容值为1928 F•g-1。量化计算结果表明，上述复合材料乃是通过Ni(OH)2与石墨烯表面功能基团的强化学作用相结合而导电，电子则自石墨烯基底经氧化缺陷向Ni(OH)2分子传递，导致Ni(OH)2带负电，从而形成Ni(OH)2纳米粒子的单向导电行为。The enhanced electrochemical properties of Ni(OH)2 by the oxidation defected graphene were studied by both experimental method and theoretical calculation. The composite material of nano-Ni(OH)2/graphene was prepared by potentiostatic deposition on the graphene substrate. Observed by TEM, the Ni(OH)2 nanoparticles were well dispersed on the graphene substrate with the diameter of 5.0±0.5 nm. The capacitance of the system measured by the electrochemical test was 1928 F?g-1. As indicated by the theoretical calculations, the composite material becomes conductive since Ni(OH)2 is combined with surface functional groups of the graphene through the strong chemical interaction. The electrons transfer from the graphene substrate to the Ni(OH)2 through the oxidation defects, which makes the Ni(OH)2 nanoparticles negatively charged and results in the unilateral conduction phenomenon.国家自然科学基金（20821063和20873063）；973项目基金（2010CB732400）作者联系地址：南京大学 化学化工学院，生命分析国家重点实验室，江苏 南京 210093Author's Address: Key Laboratory of Analytical Chemistry for Life Science MOE, School of Chemistry and Chemical Engineering, Nanjing University, Nanjing 210008, China通讯作者E-mail：[email protected]
