Abstract Inorganic solid electrolytes (SEs), such as sulfides and halides, are crucial for developing practical all‐solid‐state batteries (ASSBs) owing to their high ionic conductivities and mechanical sinterabilities. However, their sensitivity to humid air necessitates stringent dry‐room conditions during processing, which increases production costs. This study demonstrates that ultrathin (≈5 nm) superhydrophobic polydimethylsiloxane (PDMS) or fluorinated PDMS (F‐PDMS) protective layers can en

Purpose: Several artificial intelligence (AI) models for the detection and prediction of cardiovascular-related diseases, including arrhythmias, diabetes, and sleep apnea, have been reported. This systematic review and meta-analysis aimed to identify AI models developed for or applicable to wearable and mobile devices for diverse cardiovascular-related diseases. Materials and Methods: The searched databases included Medline, Embase, and Cochrane Library. For AI models for atrial fibrillation (AF

The evolution of mechanical stress resulting from electromigration in a polycrystalline thin film Al interconnect is simulated as a function of current density assuming zero stress boundary conditions. A polygranular cluster region is introduced into lines with otherwise bamboo microstructures, and results in a pair of atomic flux divergence sites and a tensile-compressive stress dipole. In the tensile stress region, the atomic diffusivity is higher than that in the compressive stress region, le

An efficient gas chromatographic profiling and pattern recognition method is described for brandy and whiskey samples according to their organic acid contents. It involves solid-phase extraction of organic acids using Chromosorb P with subsequent conversion to stable tert-butyldimethylsilyl derivatives for the direct analysis by capillary column gas chromatography and gas chromatography-mass spectrometry. A total of 12 organic acids were reproducibly identified in liquor samples (1 mL). When the

Abstract Despite their high Li + conductivity and deformability, sulfide solid electrolytes suffer from limited electrochemical stability, which prevents all‐solid‐state batteries (ASSBs) from reaching their full performance potential. Herein, a facile surface fluorination strategy is presented for Li 6 PS 5 Cl using XeF 2 as a solid‐state fluorinating agent, enabling a scalable dry process at moderate temperatures. An ≈37.3 nm‐thick uniform fluorinated layer is coated on an Li 6 PS 5 Cl surface

Thermodynamic optimization of a solid oxide fuel cell-combined heat and power system is the first step for its commercialization. This study suggests a thermodynamically optimized SOFC-CHP system through numerical modeling and simulation. An in-house numerical simulator is developed, which utilizes design variables of system components and their empirical correlations to enhance the accuracy of simulation. It is developed with C# language, equipped with graphical user interface by making use of
