The synthesis and characterization of two new Schiff base ligands containing 1,2,4-triazole moieties their oxovanadium(IV) complexes have been reported. were studied by ultraviolet-visible (UV-Vis), Fourier transform infrared (FTIR), proton nuclear magnetic resonance (1H NMR), electron paramagnetic (EPR), X-ray diffraction (XRD), conductivity measurement, cyclic voltammetry (CV), elemental analyses. molar conductance found to be relatively low, depicting non-electrolytic nature. XRD patterns...
Considering the rapidly increasing population, development of new resources, skills, and devices that can provide safe potable water clean energy remains one vital research topics for scientific community.
Abstract Summary: Polystyrene‐ block ‐poly(methyl methacrylate) nanorods were prepared by wetting ordered porous alumina templates. We systematically investigated the diameter‐dependence of their morphologies varying pore diameters templates from 400 nm down to 25 nm. If diameter exceeds period copolymer, pores accommodate a non‐integer number repeat periods. In case smaller occurrence an state could not be unambiguously verified. TEM image ultra‐thin slice containing cross‐section...
A novel natural hydroxyapatite (HAp) bioceramic was extracted from the ostrich cortical bone by thermal decomposition method. HAp characterized different analytical tools such as thermogravimetric analysis (TGA), Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) analysis, and scanning electron microscopy (SEM). Removal of organic impurities powder confirmed TGA analysis. FTIR spectra presence major functional groups phosphate (PO4 3-), hydroxyl (OH-), carbonate (CO3 2-)...
The histone deacetylase 2 (HDAC2), an enzyme involved in gene regulation, is a potent drug target for the treatment of colon cancer. Phytocompounds having anticancer properties show ability to interact with HDAC2 enzyme. Among compounds, docking scores caffeic acid (CA) and p -coumaric (pCA) showed good binding efficacy -5.46 kcal/mol -5.16 kcal/mol, respectively, small inhibition constants. higher CA compared pCA can be credited presence extra oxygen atom molecule, which forms additional...
Iridoids commonly found in plants as secondary metabolites have been reported to possess significant biological activities such anticancer, antioxidant, hypoglycemic, antimicrobial etc. The strong interactions of iridoids with cyclic-dependent kinase 8 (CDK8) protein could show inhibitory effects that modulate tumour growth. From the molecular docking calculations, some interacted effectively target CDK8 (PDB ID: 5ICP) better binding affinities −9.1, −9.0, −8.9 kcal/mol, than observed for...
<abstract> <p>Lactoferrin, a member of the transferrin family, is one promoter proteins for calcium oxalate-type kidney stone formation. It exhibits remarkable ability to interact with metals and oxalate ions. The prevalence in stones was confirmed by Fourier transform infrared spectra. quantum chemical properties dolichin A calculated density functional theory time-dependent indicate their potential hydrogen bonding nonbonding interactions receptor proteins. From molecular...
Abstract The orientation behavior of isotactic polypropylene (iPP) in α‐ and β‐crystal form was investigated by rheo‐optical Fourier transformed infrared (FTIR) spectroscopy. This method enabled quantification the degree as a feature structural changes during uniaxial elongation not only crystalline phase but also amorphous one. Molecular mechanisms can be successfully derived from experimental results. Generally, three were detected for iPP: (1) interlamellar separation phase, (2) slip...
The physical characteristics of epoxy–nCOP nanocomposites are associated with the constrained epoxy chains immobilized by octahedral nCOP particles. existence a region depends on filler dispersion and polymer/filler interactions.
In this study, decellularized fish skin (DFS) scaffold decorated with silver nanoparticles was prepared for accelerating burn wound healing. The (AgNPs) synthesized by the green and facile method using Aloe vera leaf at different incubating times were characterized X-ray Diffraction (XRD), Fourier Transform Infrared (FT-IR) Spectroscopy, Ultraviolet-Visible Spectroscopy (UV-Vis spectroscopy). characterizations confirmed that sizes of AgNPs 6 hours 12 29.1 nm 35.2 nm, respectively. After...

Abstract Flexible electronics are seamlessly integrated into our lives, from foldable displays to smart wearables, redefining interaction with technology. The use of metals and semiconductors in these flexible devices is limited due their poor bendability stretchability. Consequently, integrating conjugated polymers (CPs) a cellulosic framework has emerged as promising approach for advancing electronics. Cellulose, an abundant sustainable biopolymer, offers compelling solution the escalating...
