Multiple aromatic CH activations by a dirhenium complex have provided meta-related dimetallated arene rings in the complexes Re2(CO)8(μ-H)(μ-η2-1,2-μ-η2-3,4-C14H8)Re2(CO)8(μ-H), 3 and Re2(CO)8(μ-H)(μ-η1-1,μ-η1-3-C6H4)Re2(CO)8(μ-H), 4. Both products were characterized structurally by single crystal X-ray diffraction and DFT molecular orbital analyses.

Transition metal oxides are very promising alternative anode materials for high-performance lithium-ion batteries (LIBs). However, their conversion reactions and concomitant volume expansion cause the pulverization, leading to poor cycling stability, which limit their applications. Here, we present the quasi-single-crystal Ni(x)Co(3-x)O4 hexagonal microtube (QNHM) composed of continuously twinn...

This study aims to improve the dissolution rate of ketoprofen by preparing multicomponent crystals with tromethamine. The (equimolar ratio) and tromethamine were prepared solvent co-evaporation method. solid-state properties resulting powder characterized X-ray diffraction, DSC thermal analysis, FT–IR spectroscopy, solubility, in vitro rate. crystal structure was determined single-crystal diffr...

This is the report clarifying orientation dependence of wear behavior Co–Cr–Mo alloy. The resistance alloy with face-centered cubic (fcc) structure was found to be higher on planes in order {110}, {001} and {111}. Quantitatively, {110} 1.5 times larger than that tendency showed coincident surface hardness, as empirically suggested. However, we additionally observation worn fcc-single crystals v...
