Advanced highly precise simultaneous electrochemical detection of toxic azo dyes with Nanoengineered yttrium Iron oxide decorated functionalized carbon nanofibers.

It is essential to monitor the concentration of synthetic coloring agents in food and beverages due to their potential severe side effects on human health. In this study, yttrium iron oxide (YFO) nanoparticles were synthesized via a hydrothermal method, followed by modification with functionalized carbon nanofibers (f-CNF) through a simple sono-chemical process. The synthesized YFO/f-CNF was thoroughly characterized using various analytical techniques.

Elevated temperature fabrication of copper sulfide nanosphere implemented boron carbide nanocomposite for hyper-sensitive detection of sulfadiazine in water and urine samples.

This work introduces an innovative method for electrochemical sensing via the creation of copper sulfide-decorated boron carbide (BC) nanocomposites (CuS@BC). The emphasis is on identifying sulfadiazine (SFZ), a commonly used antibiotic and environmental contaminant, often detected as a residue in water and human urine owing to its usage in beekeeping for treating bacterial infections. The existence of SFZ presents considerable hazards to vulnerable persons, highlighting the need for accurate detection techniques.

Electrochemical determination of uric acid in the presence of dopamine and riboflavin using a poly(resorcinol)-modified carbon nanotube sensor.

In this study, an electrochemical sensor based on a poly(resorcinol) modified carbon nanotube paste electrode (P(RS)/MCNTPE) was successfully developed for the sensitive and selective detection of uric acid (UA) in the presence of dopamine (DA) and riboflavin (RFN). The sensor shows excellent performance in a 0.2 M phosphate buffer solution (PBS) at pH 7.

Polymer-assisted synthesis of ternary magnetic graphene oxide nanocomposite for the adsorptive removal of Cr(VI) and Pb(II) ions.

The presence of chromium [Cr(VI)] and lead [Pb(II)] ions in the water bodies have adverse effects on humans and aquatic life. Graphene oxide-based magnetic nanocomposites synthesized in the presence of chitosan (mGO/CS) or polyaniline (mGO/PA) as potential adsorbents for the removal of Cr(VI) and Pb(II) ions. The FTIR (Fourier transform infrared spectroscopy), EDX (Energy dispersive X-ray), XRD (X-ray diffraction) and SEM (Scanning electron microscopy) were employed to investigate the chemical composition, structural, elemental analysis, crystalline size and morphology of the nanocomposites.

Nitrite ions (NO), as one of the leading type-A inorganic-anion, showing significant-effects in the aquatic environment and also to humans health. Whereas, the higher uptake causes detrimental threat to human health leading to various chronic diseases, thus demanding efficient, reliable and convenient method for its monitoring. For this purpose, in the present research study we have fabricated the mimetic nonozyme like catalyst based colorimetric nitrite sensor.

Cu-doped mesoporous TiO photocatalyst for efficient degradation of organic dye via visible light photocatalysis.

A solvothermal method was used to synthesize the mesoporous TiO, (1-3w %) Cu-doped mesoporous TiO membrane with the help of a bioreactor. To understand the physicochemical composition of all synthesized nanomaterials, the structure, morphology and crystallinity of the materials were studied using X-ray diffractometer (XRD), Field emission scanning electron microscopy (FESEM), Fourier transform-infrared (FTIR), Energy dispersive X-ray spectroscopy (EDS) and cyclic voltammetry (CV). Under artificial light source (500 W mercury bulb) irradiations, the nano catalysts' catalytic effectiveness was examined for the azo dyes, namely Congo red.

CuO-decorated MOF derived ZnO polyhedral nanostructures for exceptional HS gas detection.

Considering that HS is a hazardous gas that poses a significant risk to people's lives, research into HS gas sensors has garnered a lot of interest. This work reports a CuO/ZnO multifaceted nanostructures(NS) created by heat treating Cu/ZIF-8 impregnation precursors, and their microstructure and gas sensing characteristics were examined using various characterization techniques (XRD, XPS, SEM, TEM, and BET). The as-prepared hollow CuO/ZnO multifunctional nanostructures had a high gas response value (425@50 ppm HS gas), quick response and recovery times (57/191s @20 ppm), a low limit of detection (1.

Comparative study of ZIF-8-materials for removal of hazardous compounds using physio-chemical remediation techniques.

The inherent toxicity, mutagenicity and carcinogenicity of dyes that are discharged into aquatic ecosystems, harming the health of humans and animals. ZIF-8 based composites are regarded as good adsorbents for the breakdown of dyes in order to remove or degrade them. In the course of this research, metal-organic framework materials known as ZIF-8 and its two stable composites, ZIF-8/BiCoO (MZBC) and ZIF-8/BiYO (MZBY), were produced via a hydrothermal process and solvothermal process, respectively, for the dangerous Congo red (CR) dye removal from the solution in water using adsorption method.
