Arsenic (As) contamination has emerged as a serious public health concern worldwide because of its accumulation and mobility through the food chain. Therefore, current study was planned to check effect Bacillus subtilis-synthesized iron oxide nano particles (Fe3O4 NP) on rice (Oryza Sativa L.) growth against arsenic stress (0, 5, 10 15 ppm). Iron nanoparticles were extracellular synthesized from subtilis with desired shape size. The formations differentiated UV-Visible Spectroscopy, FTIR,...
Abstract The elimination of hazardous industrial pollutants from aqueous solutions is an emerging area scientific research and a worldwide problem. An efficient catalyst, Ag–CuO was synthesized for the degradation methylene blue, chemical sensing ammonia. A simple novel synthetic method reported in which new plant material Capparis decidua used reduction stabilization nanocatalyst. Varying amount Ag doped into CuO to optimize best catalyst that met required objectives. Through this,...

Four new carboxylates complexes with general formula R2SnL2 and R3SnL, where R = n-butyl (1, 3), methyl (2, 4) L 4-Chlorophenoxyacetate, were synthesized in significant yields. FT-IR analysis revealed a chelating (1 2) bridging bidentate (3 coordination modes for the carboxylate ligand solid state which was further confirmed by single crystal X-ray of complex 4. The NMR data (1H, 13C 119Sn) higher number around tin center compared to R3SnL 4). A close matching observed between experimental...
Four new diorganotin(IV) complexes, including Me 2 SnL( 1 ), Bu Ph 3 ) and Oct 4 were synthesized by reacting R SnCl (where = Me, Bu, Ph, Oct) with N ′‐(3,5‐dichloro‐2‐hydroxybenzylidene)‐2‐phenylacetohydrazide H L . The ligand complexes structurally characterized various techniques, Fourier transform infrared (FT‐IR), 13 C nuclear magnetic resonance (NMR) mass spectrometry. data suggested that tin–oxygen tin–nitrogen bonds are formed during complex formation, confirming the coordination of...
Hydrogen peroxide (H2O2) is a byproduct of oxidative metabolism, acts as signaling molecule, and can induce protein DNA damage by stress. Ionic liquid-coated lignin stabilized silver nanoparticles (LAgNPs) have been used for the colorimetric detection H2O2. Both ionic liquid moieties synergistic effect on conductivity to display intrinsic peroxidase-like activity with enhanced potential catalyze oxidation substrate 3,3′,5,5′-tetramethylbenzidine (TMB). LAgNPs synthesized green synthesis...
Six new organotin(IV) complexes, [Bu2SnL] (1), [Me2SnL] (2), [Me3SnL] (3), [Bu3SnL] (4), [Ph3SnL] (5) and [(n-Oct2SnL] (6) have been synthesized from the reaction of 4-((5-chloro-2-hydroxyphenyl)ethylideneamino)methyl)cyclohexanecarboxylic acid (HL) with corresponding diorganotin(IV) dichloride/oxide or triorganotin(IV) chloride.All compounds were structurally characterized by elemental analysis, FT-IR, multinuclear NMR (1H 13C) spectroscopies powder X-ray diffraction analysis. The results...

Nanoparticle (NP) application is most effective in decreasing metalloid toxicity. The current study aimed to evaluate the effect of Bacillus subtiles synthesized iron oxide nanoparticles (Fe3O4 NPs) against arsenic (As) stress on rice (Oryza sativa L.) seedlings. Different concentrations As (5, 10 and 15 ppm) subtilis Fe3O4 NPs solution alone combination were applied results showed that at ppm significantly decreased growth rice, which was increased by low level As.
