Summary: In situ transmission electron microscopy was used to uncover nanoscale transformations during lithiation, sodiation, and potassiation of Bi2Te3 in alkali-ion batteries, with sodiation exhibiting the highest reaction kinetics. The origin of this phenomenon was elucidated through first-principles and finite-element simulations, pointing to lower interfacial strain accommodation energy and higher electrochemo-mechanical stress concentration as key factors. These insights are crucial for fast-charging alkali-ion batteries.

Summary: This study traced the structural evolution during solid-state synthesis using an in situ technique, focusing on the lithiation reaction and migration of transition metal ions. It was found that the sintering process is regulated by the competition between decomposition and lithiation reactions, which can be controlled by temperature. To maintain the layered ordering of transition metal ions throughout the synthesis process, it is desired to control the melting point and affinity of the Li sources to the cathode precursors, which simplifies the manufacturing process and improves the quality of the cathode material.

Summary: Graphitic nanoplatelets (GNPs) were treated using an ultrasonicated ozonolysis procedure to produce stable aqueous dispersions for thin film deposition using electrophoretic deposition. Zero valence (ZV) iron nanocubes were then coated onto the thin GNP films using pulsed electrodeposition. The changing magnetic character of the ferromagnetic-graphitic hybrid material was related to the nucleation density and growth of the ZV-iron nanocubes. ZV-iron was adsorbed preferentially at the oxygen sites of the GNPs, displacing oxygen groups in some configurations. Transmission electron microscopy studies confirmed that ZV-iron growth nucleated at the edges of the graphite nanoplatelets, and the magnetism of the hybrid material was affected by the convergent crystalline grain boundaries formed between adjacent ZV-iron nanocubes.

Summary: This study investigated the corrosive properties of protic ionic liquids on zinc and copper. It was found that the presence of carboxylate anions or alkanolammonium cations led to a cathodic shift in the corrosion potential, with a noticeable decrease in corrosion current for copper and an increase for zinc. The interactions between ionic liquids and metal surface were further explored, revealing that ethanolammonium cation had a stronger binding to the copper surface compared to ethylammonium cation, and nitrate anion was more tightly bound than formate anion.

Summary: The group-IV monochalcogenides, including GeS, GeSe, SnS, and SnSe, exhibit large piezoelectric responses and flexibility due to their orthorhombic structure. This study demonstrates that these monolayers can achieve similar strains upon charge injection, expanding or contracting depending on electron or hole injection. The strains obtained allow for the assessment of actuation stress and volumetric work density, indicating their suitability as actuation materials. SnS shows the greatest actuation stress and volumetric work density among the investigated monolayers. The electromechanical strains are examined through structural deformations and charge density distribution, and the introduction of charge affects the electronic properties of the monolayers. Furthermore, the piezoelectric response of these monolayers surpasses that of phosphorene and MoS2, with SnSe exhibiting the largest value, making it ideal for piezoelectric actuators.

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.
