The development of a high capacity electrode in aqueous rechargeable zinc ion batteries has attracted extensive interest. Herein, ammonium molybdenum sulfide hydrate (N-MoS) nanospheres containing S-S bonds are reported. The N-MoS/Zn system exhibits a high reversible capacity of 135.64 mA h g and excellent long-term cyclability. Moreover, an interesting dual mechanism with insertion of Zn and the breakage/formation of disulfide bonds is demonstrated.

Herein, a superhydrophobic surface was designed and fabricated based on the "lotus effect" construction mechanism. The zeolitic imidazolate framework (ZIF-90) micro-nanoparticles were initially synthesized via a one-pot method, combined with long-chain stearic acid (STA), and subsequently embedded in polyvinyl butyral (PVB) to form a superhydrophobic surface at room temperature. The superhydrophobic surface demonstrated mechanical stability and retained its superhydrophobicity with a water contact angle (CA) greater than 150°, even at a wear distance of 400 cm.

The hydration force is indispensable for understanding short-range interfacial forces in aqueous systems. Perturbation of the hydration structure by ions generates an ion-specific hydration force. Surface-force measurements on calcite surfaces have suggested that Na decreases the repulsive hydration force by directly adsorbing the surface and disrupting the hydration layers.

ConspectusProteins and peptides occur ubiquitously in organisms and play key functional roles, as structural elements and catalysts. Their major natural source is ribosomal synthesis, which produces polypeptides from 20 amino acid building blocks. Peptides containing noncanonical amino acids have long been prepared by chemical synthesis, which has provided a wealth of physiologically active compounds.
