Article Synopsis
- The aqueous extract of a specific plant acts as a precursor for quickly converting silver ions into silver nanoparticles (As-AgNPs), demonstrating significant antimicrobial activity against certain pathogens.
- The study employed various analytical techniques, including UV-visible spectrophotometry and HR-TEM, confirming the presence and characteristics of As-AgNPs on fabrics, which showed effective inhibition against bacterial growth.
- Green synthesis of silver nanoparticles offers a cost-effective, eco-friendly method for wound management, with no cytotoxic effects observed against L929 cell lines, suggesting potential for treating infectious ulcers.
Synthetic azo dyes are extensively used in the textile industries, which are being released as textile effluent into the environment presence of azo dyes in the environment is great environmental concern therefore treatment of textile effluent is crucial for proper release of the effluent into the environment. Electrochemical oxidation (EO) is extensively used in the degradation of pollutants because of its high efficiency. In this study, photo-assisted electrooxidation (PEO) followed by biodegradation of the textile effluent was evaluated.

- A new photocatalyst, BiOBr/BiYWO, was created using a one-pot hydrothermal method by varying KBr amounts (0.5 to 2.0 mmol) to improve its effectiveness under visible light.
- The best-performing catalyst, made with 1.5 mmol of KBr, achieved a decomposition efficiency of 78.3% for methylene blue, with a low bandgap of 2.51 eV and better photoluminescence compared to others studied.
- The catalyst exhibited stability and reusability over four cycles, highlighting its robust performance, and a proposed mechanism for methylene blue decomposition under light was also suggested.

September 2021
In the present work, a visible light driven AgVO/BiOI nanocomposite photocatalyst with different wt % (1, 2, 3) of AgVO was fabricated by using facile hydrothermal method. Further, the nanocomposite was characterized by FT-IR, XRD, SEM, TEM, EDS, UV-vis DRS, photoluminescence and photoelectrochemical studies. The structural characterization showed nanorods on nanosheet surface.

Factors such as bacterial density, frequency of administration and concentration of extract were analysed. Plant samples were collected from Thrissur District, Kerala, India.
View Article and Find Full Text PDFBacteria communicate within a system by means of a density dependent mechanism known as quorum sensing which regulate the metabolic and behavioral activities of a bacterial community. This sort of interaction occurs through a dialect of chemical signals called as autoinducers synthesized by bacteria. Bacterial quorum sensing occurs through various complex pathways depending upon specious diversity.
