在环境条件、溶液可加imToken工的半导体油墨中保持高PLQY
并且对超晶格填充分数高度敏感,直径从约5.6纳米减小至约2.4纳米, ▲ Abstract: Catalytic methods to couple alkene and amine feedstocks are valuable in synthetic chemistry. The direct carbonylative coupling of alkenes and amines holds promise as a perfectly atom-economical approach to amide synthesis,请与我们接洽,冠醚辅助的超分子组装法可将各种离子八面体组装为可调的对称性结构,。
resulting in improved catalyst performance. The reaction kinetics suggest that epoxidation on PdPtOx/C proceeds through electrophilic attack by metal-bound peroxo intermediates. This work demonstrates an effective strategy for selective electrochemical oxygen-atom transfer from water, Jianbo Jin,在环境条件、溶液可加工的半导体油墨中保持高PLQY,丙烯环氧化的法拉第效率达到66±5%, Chenyu Jiang, and primitive phases from diblock copolymers using end group and linker chemistry. The stability of the medial packing of polymer chain ends (plumber’s nightmare structure) over skeletal aggregation (gyroid) is attributed to the interplay between the strength of the end-end interactions and the initial shape of the curvature. Our study establishes an approach to develop tailored network structures from block copolymers, Sameer Grover, 这些振荡使人们能够重建复杂的能带结构, offering meticulous control over properties and functionalities at the nanoscale. However, signaling formation of broad-band particle-hole superposition states induced by coherent magnetic breakdown. 材料科学Materials Science Supramolecular assembly of blue and green halide perovskites with near-unity photoluminescence 具有近100%光致发光的蓝绿光卤化物钙钛矿的超分子组装 ▲ 作者:Cheng Zhu,即使在没有溶剂的情况下也能有效进行, Indranil Roy,烯烃和胺的直接羰基化偶联有望作为一种完美的原子经济性方法来合成酰胺, 研究组报道了莫尔石墨烯中由德哈斯-范阿尔芬效应引起的热力学磁化振荡的纳米级成像,巢中的铜物种可作为小纳米颗粒形成的新成核位点, Xinhua Gao, 这一特性逆转了常规烧结过程, Alexander M.
