The tandem catalytic functionalization/carboxylation of double as well as triple carbon-carbon bonds with CO2 represent an emerging research area in synthetic organic methodology.In particular,the combination of mild reaction conditions,stoichiometric acceptor/donorless conditions (visible light photoredox catalysis) and chiral catalysts contributed to a rapid development of this intriguing research area capable of creating chemical diversity/complexity from readily available unsaturated hydrocarbons and CO2 as a C1-buinding block.The most recent developments in the field have been collected in the present review article and organized,based on the different sets of π-systems/intermediates/reactive partners employed (i.e.,nickelalactones,organo-halides) as well as synthetic strategies (i.e.,visible-light photo redox catalysis).

奥氏体不锈钢长期服役于氢环境会产生氢脆,引起结构安全隐患;氢的扩散与材料晶界倾角和晶粒取向密切相关,尤其是氢扩散和晶粒取向之间的关系还未被很好地解释.针对上述问题,提出利用ABAQUS软件建立有限元模型,将奥氏体不锈钢各向异性行为和氢扩散进行耦合,以考虑晶粒取向对双晶模型氢扩散的影响,并研究3种不同晶粒取向组成的双晶模型.结果表明:晶界附近区域的应力集中由晶粒取向不同导致;应力对氢扩散有促进作用;晶粒取向与晶粒尺寸大小无关.

为了解决能源危机问题,提出了电解水技术开发清洁可持续氢能的终极途径.电催化析氧反应(oxygen evolution reac-tion,OER)是电解水制氢技术的瓶颈,二硫化钼(MoS2)在电化学OER方面得到广泛研究,然而其析氧过电位普遍高于300 mV,限制了其应用.对MoS2材料用于OER的最新发展进行了论述和总结,分析了本征MoS2材料、金属掺杂、异质材料等改性策略及结果,提出了MoS2基催化剂在全pH介质OER研究中存在的问题,展望了OER催化剂未来的发展趋势,给出了合理设计和高效改性催化剂的
利用金相、X射线衍射(X-rays of diffraction,XRD)和扭摆内耗仪对固溶处理的冷却速度和Al质量分数对Fe-18Ga合金显微组织及阻尼性能的影响进行研究.结果表明,Fe-18Ga合金的阻尼性能随着固溶处理冷却速度的下降而升高.在Fe-18Ga合金中以Al替代部分Ga,即替代体心立方Fe-Ga晶胞中Ga原子形成的置换式固溶,使材料中主要存在A2相及少量有序的L12相.添加过多或较少的Al均无法形成可以钉扎合金磁畴或位错运动的有序相;而当添加Al的质量分数为3% 时,对Fe-Ga合金的阻尼
为研究车身薄壁梁刚度与轻量化之间的关系,对客车车身中常用的矩形薄壁梁刚度表达式进行了理论推导.首先,以刚质比作为评价体系,对基于刚度特性的矩形薄壁梁结构轻量化进行理论研究.然后,将铝和钢的刚质比进行对比,得到钢替换成铝后既满足结构刚度特性又能实现轻量化的几何表达式.最后,采用理论及数值模拟2种方法,通过算例对具有刚度特性的轻量化理论进行验证,并对不同尺寸的铝矩形薄壁梁进行研究,得出刚质比与铝钢高度比之间的关系表达式,可为后续进一步的轻量化理论设计提供依据.
