Borophene: a piezocatalyst for water remediation.

Borophene is an emerging two-dimensional material exhibiting exceptional piezocatalytic activity under the influence of ultrasonic vibrations, as exemplified herein by the decomposition of highly stable organic dyes in water. After 6 minutes of exposure, borophene sheets converted up to 92 percent of a mixture of dye molecules at room temperature.

MIL-88B(Fe) MOF modified screen-printed electrodes for non-enzymatic electrochemical sensing of malathion.

An enzyme-free electrochemical approach for ultra-trace quantification of the organophosphate insecticide malathion is proposed in this study. It is premised on screen-printed carbon electrodes modified by the MIL-88B(Fe) metal-organic framework (MOF). A one-pot solvothermal method was used to synthesise MIL-88B(Fe).

NaNbO/ZnO piezocatalyst for non-destructive tooth cleaning and antibacterial activity.

Tooth discoloration and plaque formation are serious issues for dental healthcare professionals across the world. Although traditional hydrogen peroxide-based cleaning methods are efficient, they can cause enamel demineralization, periodontal irritation, and toxicity. Also, these treatments are time-taking.

Bimetallic Mn/Fe MOF modified screen-printed electrodes for non-enzymatic electrochemical sensing of organophosphate.

This study presents a novel strategy to fabricate an electrochemical sensor based on a screen-printed electrode (SPE) modified by a bimetallic Mn/Fe metal-organic framework (MnFe-MOF) for the direct determination of organophosphate pesticide chlorpyrifos. Square wave voltammetry technique was employed for the electroanalysis, and the limit of detection remained as low as 0.85 nM or 0.

NaNbO Nanorods: Photopiezocatalysts for Elevated Bacterial Disinfection and Wastewater Treatment.

In the present work, ferroelectric sodium niobate (NaNbO) nanorods are formulated to attain photopiezocatalysis for water pollutant degradation and bacterial disinfection. NaNbO nanorods, integrating the advantages of photocatalysis (generation of free charge carriers) and piezocatalysis (separation of these charge carriers), possess synergistic effects, which results in a higher catalytic activity than photocatalysis and piezocatalysis alone. Active species that are involved in the catalytic process are found to be O < OH < h, indicating the significance of piezocatalysis and photocatalysis.

High energy storage capabilities of CaCuTiO for paper-based zinc-air battery.

Zinc-air batteries proffer high energy density and cyclic stability at low costs but lack disadvantages like sluggish reactions at the cathode and the formation of by-products at the cathode. To resolve these issues, a new perovskite material, CaCuTiO (CCTO), is proposed as an efficacious electrocatalyst for oxygen evolution/reduction reactions to develop zinc-air batteries (ZAB). Synthesis of this material adopted an effective oxalate route, which led to the purity in the electrocatalyst composition.
