Research in the field of aluminum batteries has focused heavily on electrodes made carbonaceous materials. Still, capacities reported for these multivalent systems remain stubbornly low. It is believed that a high structural quality graphitic carbons and/or specific surface areas >1000 m2 g-1 are key factors to obtain optimal performance and cycling stability. Here an chloride battery presented which reduced graphene oxide (RGO) powder, dried under supercritical conditions, used as active...
Hydroperoxyl intermediate is a vital component in the mechanism of electrochemical oxygen reduction reaction (ORR) and several other important chemical reactions. The selectivity kinetics ORR are controlled by energetics *OOH (* represents active site). present work integrates iron phthalocyanine (FePc) with sulfonic acid-functionalized multiwalled carbon nanotubes (MWCNTs-SO3H). resulting composite (FePc@MWCNTs-SO3H) demonstrates significantly improved higher four-electron for compared to...
Achieving on-chip, full-UV-band photodetection across UV-A (315-400 nm), UV-B (280-315 and UV-C (100-280 nm) bands remains challenging due to the limitations in traditional materials, which often have narrow detection ranges require high operating voltages. In this study, we introduce a self-driven, on-chip photodetector based on heterostructure of hybrid gold nanoislands (Au NIs) embedded H-glass cesium bismuth iodide (Cs3Bi2I9). The Au NIs act as catalytic nucleation sites, enhancing...
Abstract Organic electrochemical transistors (OECTs) have been widely tested used for biosensing applications due to high sensitivity, low operating potential, better signal-to-noise ratio and operation in aqueous medium. The de-doping OECTs is a diffusion-controlled process which crucially depends on the geometry of channel. This report presents OECT with cylindrical channel its application detection sweat glucose concentration. were fabricated by incorporating PEDOT:PSS-coated single...

Abstract Flat panel reactors, coated with photocatalytic materials, offer a sustainable approach for the commercial production of hydrogen (H 2 ) zero carbon footprint. Despite this, achieving high solar‐to‐hydrogen (STH) conversion efficiency these reactors is still significant challenge due to low utilization solar light and rapid charge recombination. Herein, hybrid gold nano‐islands (HGNIs) are developed on transparent glass support improve STH efficiency. Plasmonic HGNIs grown an...
Long‐time chronoamperometry of electrodes immersed in nonaqueous electrolytes has been employed to investigate the mass transport and charge transfer processes which govern rate alkali metal ion intercalation in. The and, hence, current, appears be controlled by diffusion within . chronoamperometric curves were fit a previously developed model predicts current‐time behavior under control solid‐state diffusion. close agreement this with experimental data allows coefficient other parameters...
Abstract Ultraviolet (UV) photodetectors often suffer from the lack of spectral selectivity due to strong interference visible light. In this study, exceptional electrical properties graphene and unique optical carbon nitride thin films (CNTFs) are used design visible‐blind UV photodetectors. First, polycrystalline CNTFs with different thicknesses (12–94 nm) produced by thermal vapor condensation. Compared bulk powder, these have a considerable sp 2 nitrogen deficiency, which is thickness...
Metal-free, cost-efficient, redox-active electrode materials, combining graphene derivatives with nitrogen-rich polymelamine (PM), are widely explored as an interface layer for electrocatalysis and electrochemical sensor platform. However, conventional chemical routes often yield of PM suffering from impaired redox behavior, restricting their electron-transfer kinetics. Herein, optimal potentiodynamic method has been established to electrodeposit on electrochemically reduced oxide (ErGO). A...
Transient potential oscillations in a self-organized system involve sequence of mass-transfer-limited chemical reactions. Often, these determine the microstructure electrodeposited metallic films.
