Instantaneous Thermal Energy for Swift Synthesis of Single-Atom Catalysts for Unparalleled Performance in Metal-Air Batteries and Fuel Cells.

Based on experimental and computational evidence, phthalocyanine (Pc) compounds in the form of quaternary-bound metal-nitrogen (N) atoms are the most effective catalysts for oxygen reduction reaction (ORR). However, the heat treatment process used in their synthesis may compromise the ideal structure, causing the agglomeration of transition metals. To overcome this issue, a novel method is developed for synthesizing iron (Fe) single-atom catalysts with ideal structures supported by thermally exfoliated graphene oxide (GO).

Dry-Electrode All-Solid-State Batteries Fortified with a Moisture Absorbent.

For realizing all-solid-state batteries (ASSBs), it is highly desirable to develop a robust solid electrolyte (SE) that has exceptional ionic conductivity and electrochemical stability at room temperature. While argyrodite-type LiPSCl (LPSCl) SE has garnered attention for its relatively high ionic conductivity (∼3.19 × 10 S cm), it tends to emit hydrogen sulfide (HS) in the presence of moisture, which can hinder the performance of ASSBs.

Brain natriuretic peptide as a clinical screening tool for the diagnosis of Kawasaki disease.

N-terminal pro-brain natriuretic peptide (NT-proBNP) has been studied as a diagnostic screening tool for Kawasaki disease (KD). However, brain natriuretic peptide (BNP) has been less studied while has less variability among age groups. We aimed to find out if BNP can be used as a diagnostic screening tool for KD in Korea.

Round-window delivery of lithium chloride regenerates cochlear synapses damaged by noise-induced excitotoxic trauma via inhibition of the NMDA receptor in the rat.

Noise exposure can destroy the synaptic connections between hair cells and auditory nerve fibers without damaging the hair cells, and this synaptic loss could contribute to difficult hearing in noisy environments. In this study, we investigated whether delivering lithium chloride to the round-window can regenerate synaptic loss of cochlea after acoustic overexposure. Our rat animal model of noise-induced cochlear synaptopathy caused about 50% loss of synapses in the cochlear basal region without damaging hair cells.

Beneficial Role of Inherently Formed Residual Lithium Compounds on the Surface of Ni-Rich Cathode Materials for All-Solid-State Batteries.

This study validates the beneficial role of residual Li compounds on the surface of Ni-rich cathode materials (LiNiCoMnO, NCM). Residual Li compounds on Ni-rich NCM are naturally formed during the synthesis procedure, which degrades the initial Coulombic efficiency and generates slurry gelation during electrode fabrication in Li-ion batteries (LIBs) using liquid electrolytes. To solve this problem, washing pretreatment is usually introduced to remove residual Li compounds on the NCM surface.
