Abstract High-capacity Li-rich layered oxides using oxygen redox as well as transition metal redox suffer from its structural instability due to lattice oxygen escaped from its structure during oxygen redox and the following electrolyte dec... Read More
Abstract Film-type shape-configurable speakers with tunable sound directivity are in high demand for wearable electronics. Flexible, thin thermoacoustic (TA) loudspeakers—which are free from bulky vibrating diaphragms—show promise in this r... Read More
Abstract Developing a state-of-the-art anion exchange membrane water electrolyzer (AEMWE) for commercial H2 production remains a great challenge and is strongly dependent on the membrane electrode assembly (MEA). Herein, we report the first... Read More
Abstract The versatile applications of nitrile have led to the widespread use of nitrile activation in the synthesis of pharmacologically and industrially valuable compounds. We reported the activation of nitriles using mononuclear cobalt(I... Read More
The ‘2023 U-Challenge Festival,’ which showcased the research outcomes of science and engineering students contributing to innovation-led growth in the Ulsan region, took place at UNIST on November 14, 2023. The festival, now in... Read More
Abstract As the electric vehicle market continues to surge, the proper assessment of used batteries has become increasingly important. However, current technologies for assessing used batteries, which involve separately estimating the State... Read More
Abstract Facile removal of adsorbed gas bubbles from electrode surfaces is crucial to realize efficient and stable energy conversion devices based on electrochemical gas evolution reactions. Conventional studies on bubble removal have limit... Read More
Abstract Herein, we present a gel polymer electrolyte (GPE) improving nonflammability of lithium-ion batteries (LIBs) by blocking radical-initiated chain reactions which cause thermal runaway and finally fire issues. The polymer that makes... Read More
Abstract Achieving fast-charging lithium-ion batteries (LIBs) with reliable cyclability remains a significant challenge. In this study, we investigate the use of phosphorus nanolayers as a strategy to enhance the lithiation kinetics and per... Read More
Abstract Conventional solid electrolyte frameworks typically consist of anions such as sulphur, oxygen, chlorine, and others, leading to inherent limitations in their properties. Despite the emergence of sulphide, oxide, and halide-based so... Read More
