From waste to Innovation: Silver-Doped silicate ink coating from waste coal fly ash for hydrophobic antimicrobial fabric and Water-Oil separation.

Coal fly ash, a waste byproduct of coal-fired power plants rich in silica, is produced in vast quantities, exceeding 750 million tons annually. This abundance underscores the importance of finding sustainable and value-added applications for its reuse. Silver nanoparticle-silica composites represent a class of inorganically hybrid antimicrobial agents as the protection layer of cotton fabrics.

Bioactive Secondary Metabolites from Bauhinia variegata Linn. Roots: Isolation, Characterization, and Cytotoxic Evaluation.

Introduction: This study aims to isolate and characterize potential cytotoxic compounds from the roots of Bauhinia variegata Linn. (Caesalpiniaceae) and evaluate their activity against human cancer cell lines. Five compounds, namely β-sitosterol (1), piperine (2), piperolein B (3), retrofractamide A (4), and dehydropipernonaline (5), were isolated from B.

A comparative analysis of L-moments, maximum likelihood, and maximum product of spacing methods for the four-parameter kappa distribution in extreme value analysis.

The study has investigated the implications of three estimation methods, namely L-moments, Maximum Likelihood, and Maximum Product of Spacing (MPS), for fitting the four-parameter Kappa Distribution (KAPD) in extreme value analysis using Monte Carlo simulations. The accuracy of the estimates has been evaluated using root mean square error (RMSE) and bias. The paper also includes an analysis of the effect of the estimation method on the estimated quantiles considering a real-life example of annual maximum peak flows and the Generalized Normal Distribution as the error distribution.
