汽车及制造装备核心部件设计与生产是国家产业政策支持的重点方向.汽车车身大型覆盖件相对于其他覆盖件,具有轻薄、形状复杂、尺寸大等特点,常采用模具冲压成型,但模具存在选材不当会导致寿命缩短的风险.国内外实践证明,消失模铸造在生产汽车铸件方面有着巨大的发展潜力.同时,在消失模铸造技术发展的过程中,存在以下共性技术问题:铸件所使用的可发性聚苯乙烯珠粒(EPS)含碳量高达92％,易产生增碳、黑渣等缺陷;EPS模样在浇注时裂解成苯、甲苯等有害气体产物,造成环境污染;负压条件下,大型铸件凝固和冷却过程缓慢、铸件晶粒粗大
Chromatography theory shows that when the inner diameter of the chromatography column is very narrow (e.g.,1-2 μm),the maximum efficiency will be produced in liquid chromatography.In addition,the increasing demand for ultrasmall volume sample analysis has
Inspired by the intriguing structures and remarkable activities of sesquiterpenoid dimers,12 new sesquiterpenoid dimers,arte-matrovirenolides A-D (1-4) and artematrolides S-Z (8-12),were isolated from the EtOAc fraction of Artemisia atrovirens through a b
Oxidative cross-coupling reactions between two nucleophiles have become one of the most important tools to construct chemical bonds in organic synthesis methodology.Directly using hydrocarbons to synthesize valuable chemicals is an ideal and economical pr
As a key epigenetic modification,5-formylcytosine (5fC) controls many important cell functions,such as gene expression and cell differentiation.However,5fC exists in mammalian tissues and cells with low content,and its structure is highly similar to 5-met
SPONGE (Simulation Package tOward Next GEneration molecular modeling) is a software package for molecu-lar dynamics (MD) simulation of solution and surface molecular systems.In this version of SPONGE,the all-atom potential energy functions used in AMBER M
Metal nanoclusters have attracted much attention due to their ultra-small size and unique properties.The integration of protein or peptide can bring a synergistic effect on the physicochemical and physiological properties of metal clusters.Metal nanoclust
微生物资源是一类具有重要经济价值和社会价值的宝贵生物资源.国家菌种资源库于2002年开始组建, 2005年“微生物菌种资源”国家平台建设项目正式启动,甘肃省科学院生物研究所作为西北仅有的一家参建单位参与平台建设.2020年7月“我国主要沿海滩涂特色微生物资源调查”项目也开始启动,充分表明了微生物资源的重要性及国家对微生物资源的重视.
The hollow cavity of fullerenes is an ideal host for the stabilization of a variety of otherwise unstable metallic clusters,enabling the discovery of novel compounds and unconventional metal-metal and metal-carbon interactions.Meanwhile,the internal metal
Continuous-flow techniques have promoted the development of synthetic chemistry due to advantages such as outstanding mass/heat transfer,on-demand scalability,improved safety,precise regulation on reaction parameters,etc.Recently,the combina-tion of flow
