Green Chemistry-Assisted Synthesis of Metal Nanoparticles and Fabrication of Microstructurally Engineered Conductive and Endurable M@PEO Functional Films.

The present research reports the synthesis of poly-[ethylene oxide]-based composite films (500 μm) containing metal nanoparticles (NPs) [Ag ( ∼ 6 nm), Cu ( ∼ 25 nm), and Fe ( ∼ 35 nm)] as the mobile phase. The novelty of the study is in the corroboration of a plausible mechanism for the generation of metal NPs through green synthesis using herbal extracts of (Tea) and (Neem). Density functional theory (DFT) is used to optimize the phytoreductants present in both biosources, wherein the reducing and/or stabilizing functional entities are primarily hydroxyl groups (-OH).

Mechanistic insight into the selective detection of dopamine using a copper ferrite-based nanocomposite, supported by a machine learning approach.

Painless and instant analysis of neurotransmitters from an abandoned body fluid, like urine, would facilitate point-of-care (PoC) detection of several neurological disorders. As a step towards developing a non-invasive, fast, and PoC analytical tool for detecting urinary catecholamines, planar electrochemical sensors have been modified with a spinel ferrite-based nanocomposite comprising copper ferrite (CF) and reduced graphene oxide (rGO), and subsequently used for selective detection of dopamine in simulated urine. The sensors exhibited dopamine sensitivity in the range of 0.

Mesoporous Boron Subphosphide: Intrinsic Electron Deficiency Enabling Selective Low-ppm of Chemiresistive CO Detection in Harsh Environments.

Carbon monoxide (CO) is infamous for its hazardous effects, mainly because it displaces oxygen in the bloodstream. Its danger is amplified by its odorless and colorless nature, making it difficult to detect. Exposure to even low concentrations of CO (≤50 ppm) is considered harmful to human health.

Benign mid-gap halide vacancy states in 2D-bismuth-based halide perovskite microcrystals for enhanced broadband photodetectors.

Lead halide perovskites are widely recognized for their exceptional defect tolerance, setting the benchmark for high-performance optoelectronic applications. Conversely, low-toxicity perovskite-inspired materials (PIMs) typically exhibit suboptimal optoelectronic performance, primarily due to their intrinsic susceptibility to defects. In this study, we address this limitation by exploring the effects of halide vacancies in PIMs through the synthesis of non-stoichiometric CsBiBrI microcrystals (MCs) with a trigonal crystal structure, incorporating iodine vacancies.

Discovery of magnetic field line dependent anisotropic chemiresistive response in magnetite: a new piece to the puzzle of magnetoreception.

Chemiresistive materials, which alter their electrical resistance in response to interactions with surrounding chemicals, are valued for their robustness, rapid detection ability and high sensitivity. Recent research has revealed that the sensing performance of these materials can be enhanced by applying an external magnetic field. In this study, we report a novel finding in the chemiresistive behaviour of magnetite (FeO), where its response has been found to be modulated in an anisotropic manner when exposed to an external magnetic field, analogous to Earth's magnetic field.

On-Chip Full-UV-Band Photodetectors Enabled by Hot Hole Extraction.

Achieving on-chip, full-UV-band photodetection across UV-A (315-400 nm), UV-B (280-315 nm), and UV-C (100-280 nm) bands remains challenging due to the limitations in traditional materials, which often have narrow detection ranges and require high operating voltages. In this study, we introduce a self-driven, on-chip photodetector based on a heterostructure of hybrid gold nanoislands (Au NIs) embedded in H-glass and cesium bismuth iodide (CsBiI). The Au NIs act as catalytic nucleation sites, enhancing crystallinity and facilitating the vertical alignment of the interconnected CsBiI petal-like thin film.

Bi-S Bond Mediated Direct Z-Scheme BiOCl/CuSnS Heterostructure for Efficient Photocatalytic Hydrogen Generation.

The advancement of photocatalytic technology for solar-driven hydrogen (H) production remains hindered by several challenges in developing efficient photocatalysts. A key issue is the rapid recombination of charge carriers, which significantly limits the light-harvesting ability of materials like BiOCl and CuSnS quantum dots (CTS QDs), despite the faster charge mobility and quantum confinement effect, respectively. Herein, a BiOCl/CTS (BCTS) heterostructure was synthesized by loading CTS QDs onto BiOCl 2D nanosheets (NSs), that demonstrated excellent photocatalytic activity under visible light irradiation.

Structure-Property Correlation in Ba/Sr-Ca-Mg-Zn-Si-Al-O Glass: Elucidation by Experimental and Molecular Dynamics Simulation Study.

Broad band transmitting glasses from visible to mid-infrared with good mechanical strength, chemical durability, glass-forming ability, and thermal stability are preferred for optics and laser technology applications. Generally, low phonon energy glasses possess an extended transmission cutoff toward mid-infrared, but at the same time, retention of other desired properties is challenging for the researchers. In this work, we have shown that mixed alkaline earth (Ba/Sr) would have the potential to improve overall glass properties while retaining its low phonon energy when CaO is partially substituted by BaO/SrO in calcium magnesium zinc silica-aluminate (CMZSA) glass.

Thus, the advancement of highly sensitive and selective sensors for HCHO detection is imperative for safeguarding environmental and indoor air quality.

Influence of intrinsic spin ordering in LaSrCoFeO and BaSrCoFeO towards electrocatalysis of oxygen redox reaction in solid oxide cell.

The redox reaction of oxygen (OER & ORR) forms the rate determining step of important processes like cellular respiration and water splitting. Being a spin relaxed process governed by quantum spin exchange interaction, QSEI (the ground triplet state in O is associated with singlet oxygen in HO/OH), its kinetics is sluggish and requires inclusion of selective catalyst. Functionality and sustainability of solid oxide cell involving fuel cell (FC) and electrolyzer cell (EC) are also controlled by ORR (oxygen redox reaction) and OER (oxygen evolution reaction).

Unraveling the interplay of common groundwater ions in arsenic removal by sulfide-modified nanoscale zerovalent iron.

Sulphidation of nZVI (S-nZVI) has shown to significantly improve the arsenic removal capacity of nZVI, concurrently modifying the sequestration mechanism. However, to better apply S-nZVI for groundwater arsenic remediation, the impact of groundwater coexisting ions on the efficacy of arsenic uptake by S-nZVI needs to be investigated. This present study evaluates the potential of S-nZVI to remove arsenic in the presence of typical groundwater coexisting ions such as Cl, HA, HCO, PO and SO through batch adsorption experiments.

Flat panel reactors, coated with photocatalytic materials, offer a sustainable approach for the commercial production of hydrogen (H) with zero carbon footprint. Despite this, achieving high solar-to-hydrogen (STH) conversion efficiency with these reactors is still a significant challenge due to the low utilization efficiency of solar light and rapid charge recombination. Herein, hybrid gold nano-islands (HGNIs) are developed on transparent glass support to improve the STH efficiency.
