Stable neodymium gallium oxide (NdGaO and NdGaO) phases: a study on their asymmetric supercapacitor applications.

Rare-earth-based nanomaterials with exceptional electrochemical properties can be obtained a simple, low-cost, environment-friendly citrate-gel-matrix approach. Owing to their high specific capacitance, strong conductivity, and electrochemical stability, gallium-based materials are capable of withstanding numerous charge-discharge cycles, thus extending the life cycle of a supercapacitor. This tunability enabled researchers to alter the morphology and composition of the electrode to enhance supercapacitor performance.

Performance analysis of three distinct NiVO single-phase nano self-assemblies for asymmetric supercapacitor fabrication and effective detection of low-concentration hazardous herbicide.

Single-phase inorganic nanostructures with multiple applications are required for cost-effective, sustainable applications to save the environment from toxic activities. Nickel vanadate (NiVO), possessing three phases, such as NiVO, NiVO, and NiVO, acts as an effective electrode material and potential electrochemical sensors. Nickel vanadate phases (NiVO, NiVO, and NiVO) were synthesized through the gel-matrix technique, and their phase purity, crystallinity, morphology, optical properties, .

The single phase and purity of the synthesized BiMoO particles were confirmed by X-ray diffraction (XRD) and further verified by Raman analysis.

Growth optimization of single-phase novel colloidal perovskite CsBiI nanocrystals and CsBiI@SiO core-shell nanocomposites for bio-medical application.

Lead-free halide perovskites have gained attention in recent years as viable materials with more distinctive characteristics than conventional semiconductor materials. Lead-free CsBiI colloidal perovskite nanocrystal is chosen to eliminate its single-phase synthesis difficulty and implement the material in bioimaging applications. Nanostructured CsBiI perovskite composites were coated with a thin coating of SiO by an tetraethyl orthosilicate/(3-aminopropyl)trimethoxysilane injection growth method to enhance their stability in aqueous medium and biocompatibility.

Embellishing 2-D MoS Nanosheets on Lotus Thread Devices for Enhanced Hydrophobicity and Antimicrobial Activity.

Herein, we report cellulose-based threads from Indian sacred Lotus () of the Nymphaceae family embellished with MoS nanosheets for its enhanced hydrophobic and antimicrobial properties. MoS nanosheets synthesized by a coprecipitation method using sodium molybdate dihydrate (NaMoO·2HO) and thioacetamide (CHCSNH) were used as a sourse for MoS particle growth with cellulose threads extracted from lotus peduncles. The size, crystallinity, and morphology of pure and MoS-coated fibers were studied using X-ray diffractometry (XRD) and scanning electron microscopy (SEM).
