The successful development of eosin-Y and sulfur-codoped g-C 3 N 4 composite as a highly efficient photocatalyst for the regeneration NADH/NADPH (64.38%/81.14%) light-driven oxidation sulfide to sulfoxide with an yield 99.6%.
Abstract Modern strides in energy storage underscore the significance of all‐solid‐state batteries (ASSBs) predicated on solid electrolytes and lithium (Li) metal anodes response to demand for safer batteries. Nonetheless, ASSBs are often beleaguered by non‐uniform Li deposition during cycling, leading compromised cell performance from internal short circuits hindered charge transfer. In this study, concept “bottom deposition” is introduced stabilize based lithiophilic current collector a...
Abstract Aqueous zinc metal batteries (AZMBs) are emerging energy storage systems that poised to replace conventional lithium‐ion owing their intrinsic safety, facile manufacturing process, economic benefits, and superior ionic conductivity. However, the issues of inferior anode reversibility dendritic plating during operation remain challenging for practical use AZMBs. Herein, a gel electrolyte based on zwitterionic poly(sulfobetaine methacrylate) (poly(SBMA)) dissolved with different...
The purpose of machining operations is to make specific shapes or surface characteristics for a product. Conditions were traditionally selected based on geometry and finish requirements. However, nowadays, many researchers are optimizing parameters since high-quality products can be produced using more expensive advanced machines tools. There few methods optimize the process, such as minimizing unit production time cost maximizing profit. This research focused profit computer numerical...
Abstract pH is spatiotemporal variable dynamically in physiological and pathological processes, the tiny changes can result completely different processes. However, major drawbacks of conventional pH‐activatable probes are their large acid‐base transition width challenge to adjust pKa suitable for various application. In response these issues, a novel approach proposed realize sensitive general strategy construct multicolor pKa‐tunable xanthene‐based platform. probes, narrowest range just 1...
We investigated resistive switching characteristics of a top-electrode-free SnOx based random access memory (ReRAM) which was fabricated at room temperature. The layer deposited by assistance UV irradiation after two times spin coating Tin(II) acetylacetonate (Sn(AcAc)2) precursor. To minimize the coffee ring effect, mixture 2-methoxyethanol (2-ME) and ethanol used as solvent device measured direct contacting tungsten (W) probe tip on thin film in reference bottom ITO electrode. with 8 hours...
Approximate computing plays a key role in building energy-efficient high-performance digital systems, as much data and computation are required recently. This paper proposes new approximate compressor that improves accuracy with faster performance. Through analyzing the error occurring cases truth table of compressor, patterns were identified to extract simplified logic. As result evaluating performance through Vivado simulation, proposed is operating 16% using 43% less power compared exact...
Grinding is widely used as the last step of manufacturing process when a good surface finish and precise dimensional tolerances are required. However, if grinding wheels have cracks, they may lead to hazardous working environment produce poor tolerance in machined products. Therefore, should be inspected for cracks before being mounted onto machine. In this study, novel method finding possible internal aluminium oxide wheel will explored by examining natural frequency displacement using an...
