The carbon dioxide (CO2) capture and utilization strategy has emerged as an innovative multifaceted approach to counteract emissions. In this study, a highly porous muffin polyhedral barium (Ba) ̵ organic framework (BaTATB; H3TATB = 4,4',4″-s-triazine-2,4,6-triyl-tribenzoic acid) was synthesized solvothermally. three-dimensional honeycomb pore architectures were densely populated with Lewis acidic Ba(II) metal sites basic nitrogen-rich triazines. BaTATB demonstrated selective CO2 adsorption...
A new optical pH sensor based on polysulfone (PSU) and polyaniline (PANI) was developed. transparent flexible PSU membrane employed as a support. The electrically conductive pH-responsive PANI deposited onto the surface by in situ chemical oxidative polymerization (COP). absorption spectra of PANI-coated membranes exhibited sensitivity to changes range 4-12, which allowed for designing dual wavelength sensor. performance assessed measuring their response starting from high going down low pH,...

Molecular structures and electronic properties namely binding energy, band gap, electrophilicity index molecular topological analysis were studied for undoped silicon doped C 20 fullerenes favipiravir in order search possible application of the systems as drug delivery vehicles. Density functional theory (DFT) quantum atoms molecules (QTAIM) used research. having interaction edges SiC 19 … OH water …C=O gas phase...
Favipiravir is a broad spectrum antiviral drug that has shown activity against many viruses. Sequel to the recent outbreak of COVID-19, favipiravir investigated as one potential drugs for treatment SARS-CoV-2. To augment these efforts, this article reports rotational isomers, tautomeric states, electronic and spectral properties its five analogues (Cl, Br, H, CN CH3) using quantum chemcial code. The enol forms are more stable calculated keto–enol relative energies in range 7.86–10.72...

There is an increasing demand for sustainable and safe packaging technologies to improve consumer satisfaction, reduce food loss during storage transportation, track the quality status of throughout its distribution. This study reports fabrication colorimetric pH-indicative flame-retardant nanocomposite films (NCFs) based on polyvinyl alcohol (PVA) nanoclays smart applications. Tough, flexible, transparent NCFs were obtained using 15% nanoclay loading (PVA-15) with superior properties,...
Abstract The cycloterpolymerizations of single‐, twin‐, and triple‐tailed hydrophobes with hydrophilic monomer N,N ‐diallyl‐ N ‐carboethoxymethylammonium chloride sulfur dioxide afforded a series cationic polyelectrolytes (CPEs) in excellent yields. These CPEs, upon the acidic hydrolysis pendent ester groups, gave corresponding pH‐responsive acid salts, which, treatment sodium hydroxide, were converted to polybetaines (PBs), anionic (APEs), PB/APE polymers containing various proportions...
The FTIR spectrum of acetanilide (ACN) is recorded and analyzed. optimized molecular structures, harmonic vibrational wavenumbers corresponding assignments the ACN are computationally examined by using B3LYP density functional theory method together with standard 6-311[Formula: see text]G([Formula: text],[Formula: text]) basis set.
