Abstract This study investigates the mechanical, thermal, morphological, antibacterial, and water absorption characteristics of Ananas erectifolius fiber (AEF) reinforced epoxy composites filled with sawdust particulates, aiming to develop sustainable alternatives to conventional construction materials. Composites were fabricated using the hand layup method followed by compression molding, incorporating sawdust filler contents ranging from 0 to 24 g while keeping the fiber mass constant at 300 g. The composite con…

The conversion of waste feedstocks into functional nanomaterials facilitates sustainable methodologies by transforming discarded biomass, polymers, industrial by-products, and electronic waste into valuable hybrid systems. This review rigorously analyzes the chemical signatures derived from waste influence defect formation, supramolecular assembly, and hierarchical structuring across nano-, meso-, and macro-scales. A comparative evaluation of thermochemical, biological, and mechanochemical methodologies is present…

The growing demand for sustainable alternatives in textile and biomedical industries has spurred interest in natural fibers. This study aimed to evaluate the potential of Solanum nigrum stem fibers as a renewable material through comprehensive physicochemical and biological characterization. Raw fibers were extracted via water retting and subjected to a series of analyses. Structural properties were examined using X-ray diffraction and Fourier Transform Infrared spectroscopy, while thermal stability was assessed t…

Previous studies have shown that undoped and doped SnO2 thin films have better optical and electrical properties. This study aims to investigate the thermoelectric properties of two distinct semiconducting oxide thin films, namely SnO2 and F-doped SnO2 (FTO), by the nebulizer spray pyrolysis technique. An X-ray diffraction study reveals that the synthesized films exhibit a tetragonal structure with the (200) preferred orientation. The film structural quality increases from SnO2 to FTO due to the substitution of F−…
