Different amounts of a stable aqueous TiO2 hydrosol were used to fabricate paper sheets having photocatalytic activity. The was prepared in medium using titanium butoxide as precursor and acetic acid catalyst for the hydrolysis butoxide. An aging process at room temperature atmospheric pressure finally applied obtain crystalline anatase hydrosol. effects different loadings on mechanical strength barrier properties modified investigated detail. behavior TiO2-modified well methylene blue (MB)...

Abstract The present study assessed the green synthesis of aluminum oxide nanoparticles (Al 2 O 3 -NPs) by using (Al) foil waste as an Al source and date palm seed extract a reducing stabilizing agent. Several methodologies were employed to investigate -NPs, encompassing X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission (TEM), energy-dispersive (EDX) analysis. UV–visible analysis revealed presence absorption peak at...

Abstract Cellulosic wastes represent a great environmental challenge, with potential conversion to product-added value through microbial fermentation. Currently, bacterial cellulose (BC) is considered promising natural polymer for multiple applications. However, the high production cost challenges its wide application. Hence, current study evaluated applicability of paper sludge as cost-effective medium both cellulases and BC production. The local isolate Streptomyces rochei revealed highest...

The development of bionanocomposite films with improved structural morphology cellulose nanofiber reinforced polylactic acid (PLA) was achieved. new strategy attained via the grafting TEMPO oxidized nanofibers (TOCNFs) prepared from corn cops using wheat gluten protein. effect different percent TOCNFs and grafted-CNF (G-CNFs) on tensile strength Young's modulus produced were studied as well addition TiO2 nanoparticles. surface thermal analysis revealed by scanning electron microscope...

Abstract Bio-based natural wastes could be considered eco-friendly alternatives to conventional fillers for enhancing the properties and reducing cost of final rubber products. Thus, in present research, EPDM/NBR blend composites filled with kaolin mixed rice husk fibers (RHFs) were prepared. Homogeneity blends was improved by incorporation maleic anhydride (MAH) as a compatibilizing agent (1 phr), evidenced scanning electron microscopy (SEM). Of all ratios investigated, 25/75 revealed good...

In this work, conducting composites of nanocellulose (NC)/polypyrrole nanoparticles (NPPy) and silver (AgNPs), i.e., NC/NPPyAg, were synthesized for the first time, to best our knowledge, via in situ emulsion polymerization pyrrole presence surfactant dopants. The AgNPs acted as an oxidizing agent simultaneously incorporate into prepared composites. structures morphologies studied using Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), UV-Vis Spectra, thermogravimetric...

A novel cost‐saving coat was applied on paper sheets to enhance their air, water vapor, and oil resistance be used in the packaging purposes. This is based new ingredients including core‐shell pigment CoO.ZnO/SiO 2 , which composed of silica fume waste comprising 80% covered with chemically thermally stable binary oxide CoO.ZnO very low cobalt content. bind cellulosic fibers using sodium alginate, now broadly due its high enhanced grease proof properties. The addition this changed...

Abstract The current study concerns the valorization of waste rice hulls into value-added materials. To achieve this goal, first, extraction route mesoporous silica nanoparticles (SiO 2 NPs) from using citric acid as a carbon template was compared with that prepared by conventional methods incineration only. Both routes were performed at different temperatures 600 and 700°C, fabricated SiO NPs studied N physisorption isotherm, X-ray diffraction (XRD), Fourier transform infrared (FTIR),...

Fire safety is a critical criterion for designing reinforced concrete structures. With the introduction of performance-based design, structural engineers need design tools to assess capacity different elements during fire exposure. This paper proposes an analytical method predict shear beams exposed elevated temperatures. The proposed extends use existing ambient temperature methods by accounting effect temperatures on material properties. It involves heat transfer analysis, evaluation...

Abstract This study aims to investigate novel applications for chicken feather waste hydrolysate through a green, sustainable process. Accordingly, an enzymatically degraded (EDCFs) product was used as dual carbon and nitrogen source in the production medium of bacterial cellulose (BC). The yield maximization attained applying experimental designs where optimal level each significant variable recorded rose 2 times. produced BC successfully characterized by FT-IR, XRD SEM.
