CERN implements an Organization-wide heatwave action plan.
Completion of the testing - which confirms that the reactor is ready for fuel load - is a major step towards commercial operations for the second AP1000 reactor at the site. The unit is projected to e...
“一次治疗完成两个手术，既恢复正常心律又预防再次栓塞”，中南大学湘雅三医院心血管内科张志辉教授这样介绍。
尽管Ti-MOF膜在高效气体分离应用方面潜力巨大，但有关Ti-MOF膜制备的相关研究仍然很少，主要原因是钛金属源种类受限和膜材料结构和分离性能间的构效关系仍不甚明确。
基于此，大连理工大学化工学院刘毅教授课题组首次以Ti8(μ2-O)8(OOCC6H5)16团簇作为钛金属源，通过单模微波加热，在温和反应条件下经三次生长制备了富含骨架配位缺陷的优先c-轴取向MIL-125膜，其展现出优异的CO2/...
