In this study, a straightforward, eco-friendly, and facile method for synthesizing iron oxide nanoparticles (IONPs) utilizing
Biogenically synthesized silver nanoparticles (AgNP) increase the fascination over chemical ones due to their facile and green synthetic process. This study reports development of an eco-friendly cost-effective synthesis AgNPs using aqueous extract Citrus macroptera fruit peel, agricultural waste, as a sole agent with both reducing capping abilities. The formation was verified by surface plasmon resonance peak at 426 nm in UV–vis spectrum, X-ray diffraction pattern, transmission electron...
Silver nanoparticles (AgNPs) prepared by green synthesis have a lot of potentials in various fields. Among them, as an antioxidant, antibacterial agent, and nanoprobe for the colorimetric detection mercury (Hg
Transition metal complexes of Ni(II) (1), Co(II) (2) and Cu(II) (3) supported by a Schiff base ligand, namely (E)-N-(4 (dimethylamino)benzylidene)-4H-1,2,4-triazol-4-amine (L) have been synthesized. The ligand has characterized various spectral studies (1H NMR, 13C FTIR, UV–Vis ESI-MS). UV–Vis, ESI-MS elemental analysis. . Elemental analysis confirmed that form at 1:2 (metal:ligand) ratio. electrochemical behaviors the in acetonitrile also studied using cyclic voltammetry showed reducing...
Abstract To discharge the colored effluents from industries there needs to be effective and affordable treatment options. Adsorption using reduced graphene oxide (rGO) as an adsorbent is a prominent one. In this study, green coffee bean extract (GCBE) utilized safe reducing agent for reduction of (GO) synthesize rGO. The formation rGO confirmed by new peak in UV–vis spectra at 275 nm diffraction XRD patterns 22°. further substantiated change GO peak's properties FTIR, EDX, Raman weight loss...
It is evident that date fruits provide a wide variety of essential nutrients which impart potential human health benefits. In Bangladesh, the popularity and its consumption surge few-fold during Ramadan among Muslims owing to profound emotion related religious belief breaking dawn-to-dusk fasting with dates fulfilling Sunnah. The present study aimed explore microbiological quality five most popular fresh samples (Nagal, Dhapas, Boroi, Morium, Tunisia) purchased from different locations Dhaka...
Abstract A green synthetic process based on plant sources could be an alternative option to conventional chemical one synthesize nanostructured bismuth. This study explored a facile and protocol for synthesizing bismuth nanoparticles (BiNPs) in aqueous solution employing coffee bean extract as key reducing capping agent. Several techniques, including X-ray diffraction, electron microscopy, energy dispersive Fourier-transform infrared spectroscopy, thermogravimetric analysis, have been used...
A new series of [Ni(II)L2](1), [Cu(II)L2](2) and [Co(II)L2](3) (L = benzyl-2-((1E,4E)-1,5-diphenylpenta-1,4dien-3-ylidene) hydrazine carbodithioate) Schiff base metal complexes have been synthesized.The ligand its were characterized by elemental analysis, 1 H NMR, UV-Vis, FT-IR magnetic moment, molar conductance thermal analysis.The electrochemical behaviors these investigated cyclic voltammetry in DMF.The spectroscopic analyses moment value suggested four coordinated geometry for three...
The synthesis of superabsorbent polymer with Carboxymethyl cellulose using ceric ammonium nitrate (CAN) initiated acrylamide (AA) monomer through a solution based graft copolymerization has been conducted. characterizing studies were performed Fourier transform infrared (FTIR) spectroscopy, Atomic force microscopy (AFM) and swelling studies. FTIR spectra established crosslinked polymeric network structure hydrogels reaction between CMC indicating incorporation resulting the formation...
In COVID-19, cytokine storms (CS) result in higher mortality and morbidity. Our study evaluated the rate of among COVID-positive Bangladeshi adults.
Averrhoa bilimbi fruit has been studied to find out a possible source of bioactive compounds against antimicrobial and cytotoxic activity. To achieve this goal, total phenolic content flavonoid content, antioxidant, activities five different fractionates such as methanolic crude, petroleum ether, chloroform, ethyl acetate water fraction A. were investigated by UV-vis spectrophotometry, disc diffusion brine shrimp lethality test methods simultaneously. Other phytochemicals viz. carbohydrate,...
Chitosan-silver nanoparticles are prepared in nonaqueous medium. In this work, sodium dodecyl sulfate (SDS) was introduced into the dimethylformamide (DMF) solution during silver reduction from of its precursor salt AgNO 3, acting as a stabilizing agent to prevent aggregation nanoparticles, while chitosan is used solid support embedded particles therein, resulting chitosan-silver (CS-Ag) nanoparticle suspension The reaction started homogeneous system which turned heterogeneous with formation...
