Enhanced sunlight-driven catalysis for hydrogen generation and dye remediation using synergistic p-CoO/n-TiO nanocomposites.

In this study, p-CoO/n-TiO nanocomposites were synthesized using different ratios of cobalt and titanium precursors through a hydrothermal method. These nanocomposites demonstrated notable potential in photocatalytic applications for hydrogen production and orange-red dye degradation under sunlight. Various techniques, including XRD, Raman spectroscopy, XPS, FESEM, TEM, and BET analysis, were used to comprehensively characterize their structural, morphological, and optical properties.

Genetic epidemiology of osteoporosis across four microsatellite markers near the VDR gene.

The large amount of positive genetic association data in a number of bone diseases suggests functional consequences of Vitamin D receptor (VDR) gene polymorphism. In the present study, four microsatellite markers viz., D12S1633, D12S1635, D12S347, and D12S96, that lie in the vicinity of the VDR gene on chromosome 12 were selected to assess the allele distribution pattern and diversity among three groups of individuals - normal, osteopenia and osteoporosis.

C-3 Substituted Lawsonemonoximates of Holmium(III): Synthesis, Characterization, and Antimicrobial Activity.

A series of five new metal complexes of Ho(III) with C-3 substituted derivatives of lawsonemonexime (2-hydroxy-1,4-naphthalenediene-1-oxime) were synthesized. The compounds were characterized by melting point, elemental analysis, IR spectroscopy and magnetic susceptibility. The antimicrobial activity of the compounds were determined by disk diffusion method and broth micro-dilution techniques using Mueller Hinton medium against the following organisms: S.

Hydroxynaphthoquinone metal complexes as antitumor agents x: synthesis, structure, spectroscopy and in vitro antitumor activity of 3-methyl-phenylazo lawsone derivatives and their metal complexes against human breast cancer cell line mcf-7.

The C-3 substituted phenylazo derivatives of lawsone (2-hydroxy-l,4 p-naphthoquinone, III) were synthesized and characterized. The X-ray crystal structure was determined for the ligand 3-(3'-methyl phenylazo) lawsone. The copper complexes of these derivatives were found to possess 1:2 metal stoichiometry and square planar geometries with intermolecular stackings, resulting in antiferromagnetic exchange interactions.

Synthesis, Spectroscopy and Electrochemistry of Fe(II) and Fe(III) Quinonemonooxime Complexes and Their DNA Cleaving Activities.

Iron(II) and iron(III) complexes of 3,5-di-tert-butyl-o-benzoquinonemonooxime were synthesized and characterized by spectroscopic and electrochemical studies. Their ability to cleave DNA has been investigated under aerobic conditions at room temperature and in the presence and absence of H(2) O(2). The plasmid DNA pBR322 was effectively cleaved by these complexes in a concentration dependant manner.

Synthesis and Characterization of Coordinatively Unsaturated Copper (II) Complexes of 1,3-Bis(2'-Pyridyl)-1,2-Diaza-2-Butene and Their Antityrosinase Activity.

The coordinatively unsaturated copper (II) complexes of 1,3-bis(2'-pyridyl)-1,2-diaza-2- butene with different ancillary anions were synthesized which can bind to copper centers of tyrosinase enzyme. The compounds were found to exhibit inhibitory activities against mushroom tyrosinase and the nature and extent of inhibition is modulated according to the type of ancillary anions.
