A mutually correlated green protocol has been devised that originates from a sustainable production of β-Ni(OH)2 nanoparticles which is used for an efficient catalytic synthesis versatile substituted tetrazoles, under mild reaction conditions in water via simple, one-pot, eco-friendly method. The followed by derivatization into highly fluorescence active compound 9-(4-(5-(quinolin-2-yl)-1H-tetrazol-1-yl)phenyl)-9H-carbazole can be at tracer concentrations (0.1 μM) to detect as well quantify...
This work deals with the synthesis of biomolecule-based monometallic Ag and Pd bimetallic Ag–Pd nanocomposites their catalytic activity towards etherification reaction.
A mild and sustainable synthetic route was followed for the generation of biomolecule-assisted Ru nanocatalyst under open as well inert atmosphere using polyphenol morin. The characterized thoroughly by powder X-ray diffraction, N2 adsorption-desorption, high-resolution transmission electron microscopy, dynamic light scattering, photoelectron spectroscopy, absorption Fourier transform infrared fluorescence thermogravimetric analysis, inductively coupled plasma optical emission spectrometry....
Herein, we have used mesoporous Al2O3 as adsorbent and compared its efficacy with chromatographic neutral alumina for the selective adsorption separation of Th(IV). The metal ions form complex thorin Th-thorin gets selectively adsorbed on at pH 1 unlike other ions. R2 value Langmuir isotherm model was found to be highest closer 1. capacities 283, 303 328 K were 50, 51.02 51.81 µmolg−1 respectively. thorium desorbed from adsorber upon treatment trisodium citrate.
The nitration of some symmetrically tetrasubstituted azo- and azoxy-benzenes in various nitrating media was found to yield the 4-nitro derivatives cases, while more drastic conditions gave 4,4′-dinitro compounds. Some nitroazobenzenes were transformed 4-nitroazo 4,4′-dinitroazoxy derivatives.Reduction mononitroazo-, dinitroazo-, monoaminoazo, diaminoazo, azoxy under mild strong reducing agents converted whole molecule 1,4-diaminobenzene. One exception with...
The Wallach rearrangement of 3-chloro-3′-methyl- and 3-methyl-3′-nitro-azoxybenzene gave rise to the corresponding 4′-hydroxyazo derivatives with hydroxyl group attached benzene ring adjacent trivalent nitrogen bridge, while 2,2′,5,5′-tetrachloro-4′-nitro- 2′-nitro-4,4′,5,5′-tetrachloro-azoxybenzene were hydroxylated in ortho para positions respectively on pentavalent bridge.Oxidation 3-methyl-3′-nitro-and 3-chloro-3′-methyl-azobenzene α-isomers, which was proved by bromination reduction...
Abstract The work discusses about the synthesis of indium-alizarin red S complex followed by its application toward sensing F¯ ion. At first, interaction between indium and alizarin dye was studied at three different pH medium, 4, 7 9, which gave best result. so obtained then utilized for ratiometric fluoride ion using absorption spectroscopy with variation temperature. lowest limit detection (0.040 mM) 313 K. mechanism investigated isothermal titration calorimetry. endothermic nature shows...
BCS class II is well-known for the drugs, having poor aqueous solubility and high permeability. Simvastatin also categorized as II, suffering from solubility, affecting its bioavailability. In an attempt to resolve this problem, solid dispersions of simvastatin were prepared by spray-drying method. Solid with PVP K25 aerosol in ratio (1:1:1 1:5:1) without aerosil 200 (1:1 1:5) spray drying The dissolution test showed enhancement compared pure drug nearly equal marketed formulation “SIMVOTIN...
