Summary: This study proposes a strategy for the protection of negative electrodes in aqueous zinc ion batteries (AZIBs) by artificially constructing a Ni-Zn alloy layer as a solid-electrolyte interface (SEI). The Ni-Zn alloy layer acts as a dynamic shield at the electrode/electrolyte interface, guiding the horizontal deposition of zinc and suppressing dendrite formation. The Ni-Zn alloy symmetric cell exhibits significantly improved cycle life and stable operation.

Summary: Agar gel pads have been used for electrochemical measurements, with a focus on establishing a standard method for measuring the stability of zinc corrosion product layer. The corrosion product layer resistance is a crucial factor, as higher resistance indicates better protection. However, the resistance level for freshly produced zinc samples is still unknown. Adding zinc acetate to the agar gel pads can prevent the formation of surface layer and allow measurement of almost corrosion product-free zinc surface.

Summary: In this study, choline chloride (CC) was used as an additive in aqueous ZnCl2 electrolyte to improve the electrochemical stability of zinc plating/stripping. The adsorption of choline cation on the zinc anode surface inhibits zinc dendrite growth, while the -OH group disrupts the initial hydrogen bond networks in the electrolyte, alleviating water-induced side reactions. The Zn parallel to Zn symmetric cell demonstrates stable cycling for over 1700 h (1.0 mA cm(-2), 0.5 mA h cm(-)(2)).

Summary: This study investigated the interactions between nickel and zinc in different populations of hyperaccumulator plants, as well as the potential role of histidine in their uptake and translocation. The results showed that zinc inhibited the uptake and translocation of nickel, while nickel had minimal effect on zinc uptake. Exogenous histidine supply also had varying effects on the translocation of zinc and nickel in different populations of hyperaccumulator plants.

Summary: This study investigated the structure, morphology, and sonophotocatalytic activity of Ni-Zn-Co ferrite nanoparticles embedded in a SiO2 matrix. The nanoparticles were synthesized using a modified sol-gel method and were characterized using thermal analysis, X-ray diffraction, and transmission electron microscopy. The results showed that the particle sizes ranged between 34 and 40 nm and exhibited optical responses in the visible range. The best sonophotocatalytic activity was observed for Ni0.3Zn0.3Co0.4Fe2O4@SiO2.

Summary: This study demonstrates the potential of extrusion-based additive manufacturing (AM) Mg-Zn scaffolds as biodegradable bone-substituting biomaterials. Through pre-alloying of Mg-Zn powder, the corrosion resistance and mechanical properties of the scaffolds were significantly enhanced. The in vitro biodegradation rate and corrosion rate of the Mg-Zn scaffolds were reduced compared to pure Mg scaffolds. The scaffolds also showed favorable cytocompatibility with preosteoblast cells.

Summary: In moderately alkaline NaCl solution, carbon steel samples with crack-free zinc-nickel coatings were polarized with a small anodic overpotential, leading to the development of a mud-crack pattern on the coatings and the growth of simonkolleite. The resulting current density switched from strongly anodic to small cathodic values as the coating surface was almost fully covered by a compact simonkolleite layer.

Summary: Aqueous zinc-based batteries are expected to be low-cost and high energy density, however, dendrite formation during charging remains a major issue. In situ TEM observations revealed that dendrite growth from the zinc anode causes short-circuiting and cycle degradation in zinc-based batteries. Characterization of electrochemical zinc deposition is crucial for realizing long life rechargeable zinc-based batteries.

Summary: In this article, a novel catalytic reaction using Pd(0) and Bronsted acid is reported for the synthesis of biologically important imidazolidinone-fused N-heterocycles through redox-neutral intramolecular N-allylation of indoles and pyrroles with alkynes. This atom-economical method is applicable to a wide range of substrates and eliminates the need for leaving groups or oxidizing agents commonly used in traditional allylation reactions.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
