In this study, the synthesis and characterization of exopolysaccharide-stabilized sliver nanoparticles (AgNPs) was carried out for degradation industrial textile dyes. Characterization AgNPs done using surface plasmon spectra UV-Vis spectroscopy, X-ray diffraction (XRD) Raman spectroscopy. The morphological nature determined through transmission electron microscopy (TEM), scanning (SEM) atomic force (AFM), which indicated that were spherical in shape, with an average size 35 nm. thermal...
Drug-resistant superbugs (DRS) were isolated from hospital sewage waste and confirmed by a 16S rDNA molecular technique as B. filamentosus , flexus P. stutzeri A. baumannii .
Intrinsically disordered proteins (IDPs) can form biomolecular condensates through phase separation. It is recognized that the conformation of IDPs in dense and dilute phases, as well at the...
Abstract Turbinaria ornata (TO) extract was tested as green corrosion inhibitor on mild steel (MS) coupons in conc. HCl medium with an efficiency of 100% at 25 g l −1 during 5 min exposure. Antibacterial efficacy performed against 16 S rDNA identified marine biofilming bacteria (MBB) and human pathogenic (HPB). Maximum inhibition growth mm MBB observed Bacillus megaterium (MBF14 - AB894827) 20 HPB Escherichia coli (B5 NCIM 2931). Similarly, minimum 10 witnessed Pseudomonas sp., (MBF9...
Multidrug-resistant strains (MDRs) are becoming a major concern in variety of settings, including water treatment and the medical industry. Well-dispersed catalysts such as BiPO4, ZnO nanoparticles (NPs), different ratios BiPO4/ZnO nanocomposites (NCs) were synthesized through hydrothermal treatments. The morphological behavior prepared was characterized using XRD, Raman spectra, PL, UV-Vis diffuse reflectance spectroscopy (UV-DRS), SEM, EDX, Fe-SEM. MDRs isolated identified by 16s rDNA...
Alternative treatment strategies for urinary tract infections (UTIs) are becoming more necessary due to increasing drug resistance patterns in uropathogens. Nanoparticle-based therapeutics is emerging as a way treat UTIs. In the present study, using Turbinaria ornata extract, silver nanoparticles (AgNPs) were synthesized, characterized, and their anti-uropathogenic activity was evaluated. The stability formation of synthesized To-AgNPs confirmed by UV-visible spectroscopy, FTIR, XRD, SEM,...
Metallofullerenes have many possible uses in technology and even bio-medical applications. Some fullerenes been found to two incarcerated metal atoms such as M2@C80 (M = La, Ce, etc.). We calculated the structural electronic properties of Ce2@C80 using density functional theory (DFT). Ce is known be preferentially incorporated into Ih symmetric C80 isomer La does La2@C80. that has a D3d ground state structure binds different type binding site compared other cerium containing fullerenes,...
Ce has been found experimentally to be preferentially incorporated into the C82 isomer of C2v symmetry as have other lanthanoids in M@C82 (M = La, Pr, Nd, etc.). We investigated underlying reason for this preference by calculating structural and electronic properties Ce@C82 using density functional theory. The ground-state structure is cerium atom attached six-membered ring on C2 axis C82−C2v cage, encapsulated perturb carbon cage due chemical bonding. favor chemisorption site 0.62 eV...
ABSTRACT Polyvinylidene fluoride (PVDF) membranes with modified membrane morphology were prepared by phase inversion process using iron alkoxide as a novel pore‐forming additive (PFA). Higher pure water flux was observed for PVDF/PFA (iron alkoxide) treated 5% HCl, due to higher porosity produced the leaching out of additive. The untreated containing 0.04% showed ~99% efficiency oil removal from surfactant‐stabilized oil–water emulsion. After acid treatment, there slight decrease in...
We assessed the spatial and temporal variations of pollution indicators geochemical trace metal parameters (23 in total) from water sediment (144 samples) three different eco-niches (beach, fishing harbor, estuary) larger coastal cities southern India (Cuddalore Pondicherry) for one year. A total 120 marine Pseudomonas isolates were challenged against concentrations copper solutions 10 antibiotics heavy antibiotic resistance approaches, respectively. The study shows that 4.16% could survive...
