There is a key missing point in the research field of zinc metal batteries (ZMBs); that is, no one pays attention to the crystal growth of byproducts. In this paper, from the perspective of crystallography, a method of disturbing the crystal growth of corrosion byproducts is proposed to improve the serious water-related corrosion in ZMBs. In consideration of the thermodynamics and dynamics of crystallization, the corrosion inhibitor (CI) molecules are introduced to envelop the active growth sites of byproduct crystals and increase the surface free energy change (Δ), thus leading to a positive free energy change (Δ) unfavorable for crystal formation and growth.

Despite major advances in the management of pediatric PAH in recent years with the development of PAH-specific drug therapy and therapeutic strategies, prognosis still remains unsatisfactory for many children. The Potts shunt, as a palliation in patients with cyanotic congenital heart defects first, receives its 'second life' in treating PAH by creating a shunt between the pulmonary artery and the descending aorta to alleviate right heart burden.

However, the regulation of surface *H is still overlooked, and without intervention, the competing hydrogen evolution reaction is kinetically more favored over the NORR, leaving the current system as far from satisfactory. Herein, based on reverse utilization of the Sabatier principle, a series of FeNi substitutional solid-solution alloys (SSAs) are synthesized to manipulate *H behavior for enhanced NORR.

Despite recent advances in the exploration of topological domains in complicated perovskite oxide superlattices, these exotic ferroic orders are unavoidably disrupted at the atomic scale due to intrinsic size effects. Here, based on first-principles calculations, we propose a new strategy to design robust ferroelectricity in atomically thin films by properly twisting 2 monolayers of centrosymmetric SrTiO.

The cutting-edge Pd-based nanomaterials for acidic ORR are hindered by their low intrinsic activities and significant CO poisoning, stemming from the challenge of simultaneously optimizing surface adsorption toward various adsorbates. Herein, we introduce an ultrathin PdRhCu ternary metallene (PdRhCu metallene) for boosting acidic ORR in PEMFC.

Ferroptosis is a unique form of cell death driven by iron-dependent lipid peroxidation, with regulatory mechanisms involving metabolic dysregulation and imbalance in redox systems. Ferroptosis is closely related to various immune cells in the tumor immune microenvironment, including both anti-tumor and pro-tumor immune cells, and it demonstrates significant potential in tumor immunotherapy. A systematic review of the regulatory mechanisms of ferroptosis and its relationship with immune cells can provide deeper insights into its application prospects in tumor immunotherapy.

The widely accepted d-band center, even with consideration of the d-band width, usually fails to describe variations in AOR reactivity in many practical conditions, and a more accurate activity descriptor is necessary for a less empirical synthesis path. Herein, the upper d-band edge, ε, derived from the d-band model, is identified as an effective descriptor for accurately establishing the descriptor-activity relationship.

With the growing demand for high-voltage and wide-temperature range applications of lithium-ion batteries (LIBs), the requirements for electrolytes have become increasingly stringent. While fluorination engineering has enhanced the performance of traditional solvent systems, it has also raised concerns regarding cost, environmental hazards, and low reduction stability. Through strategic molecular bond design, a novel class of low-temperature (LT) solvents-siloxanes-is identified, meeting the demands of LT and high-voltage applications in LIBs.
View Article and Find Full Text PDFModulating the "trade-off" between activity and durability of Pd-based alloys while eliminating the dissolution of the nonprecious metal element issue is highly significant for the advancement of commercializing anion-exchange membrane fuel cells (AEMFCs). Herein, by harmonizing composition and ligand effects and targeting the stability concerns of Pd-based alloys, we propose PdRhNi ternary medium-entropy-alloy (MEA) networks (PdRhNi ANs) as exceptionally efficient oxygen reduction reaction (ORR) electrocatalysts via ligand effect. The results of theoretical calculations provide compelling evidence that the ligand effect of Ni in PdRhNi ANs, which can endow an inductive effect to reshape the electronic configuration to induce a reduced energy barrier in the rate-determining steps, optimizes the adsorption energy of O-related intermediates and lowers the d-band center of metal species, collectively boosting the anti-CO capacity and the ORR efficiency.
