Polyhedral oligomeric silsesquioxane (POSS)-based materials, poly-POSS-Tn [n = 8 (1), 10 (2), 12 (3), and mix (4)], were prepared in high yields via free radical polymerization of corresponding pure forms methacrylate-functionalized POSS monomers, MMA-POSS-Tn (n 8, 10, 12), the mixture form, MMA-POSS-Tmix. Powder X-ray diffraction (XRD) spectra BET analysis indicate that 1–4 are amorphous materials with surface areas (683–839 m2 g–1). The total pore volumes follow trend: poly-POSS-T12 >...
Nanocomposites of polydiacetylene (PDA) and magnetic nanoparticles (MNPs), exhibiting irreversible thermochromism, have shown potential for use as nanothermometers. This type nanocomposite, however, does not allow measurement the real-time temperature. In this study, we introduce first example PDA-based nanocomposites, reversible thermochromism colorimetric response to both acidic basic conditions. Zinc ferrite (ZnFe2O4-MNPs) decorated surface PDA/Zn2+ assemblies, forming PDA/Zn2+/ZnFe2O4...
A titania-entrapped silica hollow nanostructure was prepared using two consecutive coating processes, followed by calcination. The hydrothermal treatment of D-glucose assisted polyethylene glycol used to form a carbon layer over the titania surface. resulting composite fabricate on top hydrolyzing tetraethyl orthosilicate in strong base. nanoparticles were then released but still trapped inside after Scanning and transmission electron microscopic techniques employed determine morphology...
Quantum yields for the photoisomerization of trans,trans-1,4-diphenyl-1,3-butadiene (tt-DPB), determined in benzene, cyclohexane, methylcyclohexane, hexane, and perfluorohexane, confirm low values reported earlier benzene cyclohexane reveal even lower last two solvents. In contrast to trans-stilbene (t-St), fluorescence torsional relaxation leading do not account exclusively S1tt-DPB decay. Competing radiationless singlet excited-state decay pathways exist tt-DPB, which lead may involve...
A reroute process of Hummers' method was carried out to reduce some steps in the synthesis highly exfoliated graphene oxide (HEGO). Using pure KMnO4 and NaNO3 concentrated H2SO4, HEGO successfully prepared contain extra carbonyl functional groups that helped stabilize GO layer exfoliation. The oxidation reached its completion by one straight temperature level at 35 °C within a short reaction time (4 h). obtained observed be dispersible through atomic force microscopy (AFM), scanning electron...
ABSTRACT: Bituminous activated carbon (AC) has been widely used as a sorbent for adsorption of non‐polar species, but its performance removal ionic species such heavy metals not efficient. In this study, AC was modified with chitosan nanoparticles (CN) using facile methods dip coating and wet impregnation. The CN‐coated demonstrated an increase in Cr(VI) efficiency both kinetics capacity. capacity the (mg/g) more than twice that uncoated (36.36 mg/g), or pure (32.57 mg/g). sizes synthesized...
Zinc ferrites (ZnFe 2 O 4 ) nanoparticles were successfully prepared by the simple co-precipitation method. The effects of calcination temperature and amount surfactant on microstructure zinc ferrite products studied. characterized with X-ray diffraction (XRD), Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR) UV-Vis diffuse reflectance (DRS). XRD results confirmed formation a cubic spinel structure in all samples. SEM revealed that molecules play crucial...
In this study, a laccaic acid-modified TiO2 photocatalyst (Lac-TiO2) was prepared via an impregnation method with 0.50, 1.00, 2.50, and 5.00 wt.% acid. The products’ physical properties were examined through X-ray powder diffraction (XRD), field emission scanning electron microscopy (FE-SEM), photoemission spectroscopy (XPS), UV-Vis diffused reflectance (DRS), Fourier-transform infrared (FTIR), nitrogen adsorption/desorption, photoluminescence (PL) spectroscopy. A possible photocatalytic...
