The aim of this work was to synthesize semiconducting oxide nanoparticles using a simple method with low production cost be applied in natural sunlight for photocatalytic degradation pollutants waste water. Iron titanate (Fe 2 TiO 5 ) an orthorhombic structure were successfully synthesized modified sol–gel and calcination at 750°C. as-prepared Fe exhibited moderate specific surface area. mesoporous possessed strong absorption the visible-light region band gap estimated around 2.16 eV....
Emission of greenhouse gases and infectious diseases caused by improper agro-waste disposal has gained significant attention in recent years. To overcome these hurdles, can be valorized into valuable bioactive compounds that act as reducing or stabilizing agents the synthesis nanomaterials. Herein, we report a simple circular approach using Citrus reticulata Blanco (C. reticulata) waste (peel powder/aqueous extract) green capping/stabilizing Zn nitrate/acetate precursors to synthesize ZnO...
The aim of this study was to develop an active alginate packaging film incorporating antioxidant Fe2TiO5 and antibacterial ZnO nanoparticles, obtained by green synthesis utilizing citrus peel waste. average particle size estimated as 10 nm for 50 Fe2TiO5. Films were prepared using 2.33% (w/v) sodium with 0.11% and/or nanoparticles. inclusion nanoparticles resulted in a noticeable colour difference, reduced the transparency, increased UV light protection improved thermal stability film. dry...
Abstract Biosensors need to meet the rising food industry demand for sensitive, selective, safe, and fast safety quality control. Disposable colorimetric sensors based on gold nanoparticles (AuNPs) localized surface plasmon resonance are low‐cost easy‐to‐perform devices intended rapid point‐of‐need measurements. Recent studies demonstrate various facile versatile AuNPs‐based analytical platforms detection of bacteria their toxins in milk, meat, other foods. In this review, we introduce...
Ni foam is an extensively used current collector and substrate in investigations of electrochemically active materials such as supercapacitors electrocatalysts for oxygen hydrogen evolution reactions. This material relatively cheap, porous, conductive has a large specific surface area, all which make it good substrate. We investigated Ni-Mg ferrites NiMn2O4 electrochemical energy storage. These materials, when loaded on foam, gave promising capacitance values: 172 F/g (at 2 mV/s) 6 M KOH 242...

Field emission scanning electron microscopy transmission microscopy, X‐ray diffraction, photoelectron spectroscopy Raman confirmed the formation zinc‐ferrite with a mixed spinel structure small amounts remaining as impurities. Thick film paste formed screen printed on test interdigitated PdAg electrodes alumina substrate. Formation porous Hg porosimetry....
In this work we have characterized and compared chitin sourced from exoskeleton of Tenebrio molitor larvae fed with polystyrene or plastic kitchen wrap combined bran in the ratio 1: 1 only bran. Analysis frass by ATR-FTIR showed very similar spectra confirmed degradation feed components, while analysis verified absence any residue. Deproteinization followed demineralization produced 6.78-5.29 % chitin, showing that (polystyrene wrap) diet resulted heavier insect exoskeleton, but yielded...
Glyphosate is a widely used broad-spectrum herbicide for controlling grassy weeds, but its potential hazards remain topic of significant debate.
