The crystal structure of the first acesulfame-metal complex, namely tetraaquabis[6-methyl-1,2,3-oxathiazin-4(3H)-onato 2,2-dioxide-kappaN]cobalt(II), [Co(C4H4NO4S)2(H2O)4], is reported. The Co(II) ion resides on a twofold axis and is coordinated by four aqua ligands defining the basal plane and by two monodentate acesulfamate ligands, via their ring N atoms, in the axial positions. Two intra- and three intermolecular hydrogen-bonding interactions stabilize the crystal structure and form an infinite three-dimensional lattice.

Paramyxovirus membrane fusion requires an attachment protein for receptor binding and a fusion protein for membrane fusion triggering. Nipah virus (NiV) attachment protein (G) binds to ephrinB2 or -B3 receptors, and fusion protein (F) mediates membrane fusion. NiV-F is a class I fusion protein and is activated by endosomal cleavage.

Zinc oxide (ZnO) is a semiconductor with a wide range of applications, and often the properties are modified by metal-ion doping. The distribution of dopant atoms within the ZnO crystal strongly affects the optical and magnetic properties, making it crucial to comprehend the structure down to the atomic level. Our study reveals the dopant structure and its contents in Eu-doped ZnO nanosponges with up to 20% Eu-O clusters.

A pair of aza-BODIPY isomers, 1,7-di--butyl-3,5-dinaphthyl (Nap-BDP) and 1,7-dinaphthyl-3,5-di--butyl (revNap-BDP), were prepared in this study. According to the single crystal X-ray analysis, Nap-BDP exhibited an orthogonal structure. Owing to the difference in orthogonality and -Bu rotation between Nap-BDP and revNap-BDP, their spectral performances, including maximum absorption and emission, full width at half maximum, fluorescence quantum yield, photostability, singlet oxygen generation and photothermal conversion efficiency, were obviously different.

Intelligent soft robots that integrate both structural color and controllable actuation ability have attracted substantial attention for constructing biomimetic systems, biomedical devices, and soft robotics. However, simultaneously endowing single-layer cholesteric liquid crystal elastomer (CLCE) soft actuators with reversible 3D deformability and vivid structural color changes is still challenging. Herein, a multi-responsive (force, heat and light) single-layer 3D deformable soft actuator with vivid structural color-changing ability is realized through the reduced graphene oxide (RGO) deposition-induced Janus structure of the CLCE using a precisely-controlled evaporation method.

Although cisplatin is widely used as a first-line chemotherapy agent, it has significant side effects. Herein, we synthesized a Pt(II) complex (Pt1) derived from o-vanillin-4-phenylthiosemicarbazone ligand, and confirmed its crystal structure by X-ray crystallography. Complex Pt1 exhibited potent anticancer activity against various tested cancer cell lines, with particular efficacy against HepG-2 cells.
