Water-soluble carboxymethyl chitin (CMCT) 1a–b, and chitosan (CMCS) 2a–b derivatives were synthesized evaluated for antibacterial activity. The compounds characterized by Fourier transform infrared spectroscopy (FT-IR) X-ray diffraction (XRD). Thermal properties of the studied thermogravimetric analysis (TGA) their surface morphologies examined scanning electron microscopy (SEM). Antibacterial activity (CS) 2 tested against both gram-negative (Shigella flexneri, Enterococcus faecalis,...
In the current study, association and phase separation of cationic tetradecyltrimethylammonium bromide (TTAB) nonionic Triton X-100 (TX-100) surfactants with promethazine hydrochloride (PMH) were investigated in aqueous ammonium-based solutions. The micellization nature TTAB PMH drug mixture was examined by evaluating critical micelle concentration (CMC) counterion binding extent (
In this report, we study the Yttrium-doped Barium Titanate (Y-BT) Ba1 - xYxTiO3 (with x = 0.00, 0.01, 0.03, 0.05, 0.07 mmol) perovskite ceramics synthesized by sol-gel method. The as-made powder samples were pressed into a pellet shape and subsequently sintered at 1300 °C for 5 h in air. structural, morphological, electrical, optical properties of investigated X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), impedance analyzer, UV-Vis-NIR Spectroscopy...
Phase separation behaviour of non-ionic surfactants (NISs)-drug in aq. hydrotropes (HDTs) has appealed interest to researcher over the decades. Herein, we have investigated clouding phenomenon and physico-chemical variables TX 100 promethazine hydrochloride (PMH) drug mixture presence different HDTs. Study reveals that cloud point (CP) is dependent on concentration HDTs aqueous media. CP values increase with augmentation concentrations while at nearly mmol kg−1 follow trend:...
In recent years, contamination of aquatic ecosystems by antibiotics, especially tetracyclines (TCs), has become a significant concern. this study, we have synthesized reduced graphene oxide (GrGO) using jute leaf extract as green reducing and stabilizing agent for the reduction (GO). The GO itself was from graphite derived waste dry-cell batteries, making process simple cost-effective. We aimed to explore its potential an adsorbent rapid efficient removal TCs aqueous media. Characterization...
A new concept of charge stabilization via delocalization the π-cation radical species over donor macrocycle substituents in a relatively simple donor−acceptor bearing multimodular conjugates is reported. The newly synthesized systems were composed three covalently linked triphenylamine entities at meso position porphyrin ring and one fulleropyrrolidine fourth position. expected to act as energy transferring antenna units enhance electron donating ability both free-base zinc(II) derivatives...
Interaction of moxifloxacin hydrochloride (MFH) with tetradecyltrimethylammonium bromide (TTAB) along Triton X-100 (TX-100) under different experimental conditions has been carried out using multiple physico-chemical techniques. The micellar parameters like critical micelle concentration (cmc), counter ion binding (β), thermodynamic such as ΔGm0, ΔHm0, and ΔSm0etc. associated the drug-TTAB interaction have determined. changes values cmc TTAB by addition drug indicate existence TTAB-MFH...
Hydroxyapatite (HAp) synthesis was achieved through a hydrothermal method involving orthophosphoric acid and calcium hydroxide. Different organic modifiers such as urea, naphthalene, palmitic were applied in the reaction system to modify crystallite size along with morphology of HAp. The synthesized HAp validated
Fish scale utilized biogenic synthesis of CuO nanoparticles for antibacterial application.
Mn-doped NiO NPs, synthessized by chemical precipitation, showed reduced size and increased bandgap with higher doping, maintaining FCC structure even up to 8 wt%.
Our study aims to evaluate the chemical profiles and antioxidant activities of a methanolic extract Sterculia villosa bark (MESV) Vernonia patula whole plant (MEVP). The profiling MESV MEVP was performed via gas chromatography-mass spectrometry (GC-MS), which identified 52 33 compounds, respectively. 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay indicated that both displayed concentration-dependent scavenging activities, half-maximal inhibitory concentration (IC50) values for MEVP, MESV,...
MAX phase composites are gaining great attention for their excellent attributes in high-temperature applications like aerospace, energy, and nuclear industries. However, tailoring thermal thermomechanical properties better performance...
