Simple spectrophotometric method for the estimation of accessible amino groups and preparation polyurethane nanocomposites.
The graphene oxide (GO) interaction with methylene blue (MB) cationic dye was studied in an aqueous solution at different pH during MB adsorption. mutual of GO surface and evaluated by Fourier transform infrared spectroscopy (FTIR) X-ray diffraction (XRD). π- π electrostatic are the main types interactions, XRD data show monomeric arrangement cation GO. functional groups point zero charge (PZC) were determined acid-base titration. Suitability zeta-potential measurement titration method...
Pure titanium and cerium oxides their composites were prepared by the modified method of homogeneous hydrolysis with urea as precipitating agent. The as-synthesized nanostructured examined XRD, XPS, microscopic techniques (SEM, HRTEM), nitrogen physisorption, vibrational spectroscopies (FTIR, Raman). Decontamination ability samples towards toxic organophosphorus compounds was determined two methods. reactive adsorption warfare agent simulant Dimethyl methylphosphonate (DMMP) observed in situ...
The phosphatase-mimetic ability of nanocrystalline cerium oxide was demonstrated using thiamine pyrophosphate (TPP) and nicotinamide adenine dinucleotide (NAD) as model compounds.
Natural raw mineral tungstenite (WS<sub>2</sub>) was exfoliated to single-layer sheets using high intensity ultrasound.
Nanocrystalline cerium oxide (CeO2) was used as an effective catalytic and adsorption material for the safe removal of selected phosphorus compounds. Several CeO2 samples were prepared by a simple coprecipitation method with subsequent annealing at temperatures between 400–600 °C, their sorption ability inorganic phosphates studied together to decompose organophosphorus compound - paraoxon methyl (PO) goal find relations activity materials. It found that complex set physical chemical...
Nanoceria accelerates dramatically not only the dephosphorylation of energetically rich biomolecules such as adenosine triphosphate (ATP), but also cleavage highly resistant phosphodiester bonds in 3′,5′-cyclic monophosphate (cAMP).
Phospholipase C and D-like activity high virucidal properties of nanoceria are described.
Nanoceria is a promising nanomaterial for the catalytic hydrolysis of wide variety substances. In this study, it was experimentally demonstrated first time that CeO
Herein we describe a successful protocol for graphite exfoliation using biphasic liquid system (water/dichloromethane, DCM) containing ionic liquids (ILs; 1,3-dibenzylimidazolium benzoate- and 1-naphthoate). The use of (surface active) IL sonication led to stable DCM/water (O/W) emulsion, which enhanced graphene formation, suppressed its re-aggregation decreased shear/cavitation damage. O/W emulsion stabilization by the ILs was studied dynamic light scattering (DLS), whereas their...
A simple low-temperature water-based and one-pot synthesis was developed for the preparation of nanocrystalline CeO2 that used degradation toxic organophosphate pesticide parathion methyl. By changing reaction temperature in range from 5 °C to 95 °C, several properties (i.e., crystallinity, grain size surface area) nanoceria can be easily controlled. The catalytic decomposition methyl its product 4-nitrophenol highly dependent on temperature. It demonstrated at low (i.e. °C), with very small...
ZnO doped with Cr, Mn, Fe, Co, Ni and Cu was prepared by homogeneous hydrolysis of sulfates urea. The samples were annealed at various temperatures characterized X-ray powder diffraction, UV/VIS reflectance spectroscopy, BET (Brunauer-Emmet-Teller) surface area porosity measurements. photocatalytic activity the evaluated measuring degradation an organic dye Reactive Black 5. morphology determined scanning electron microscopy atomic force microscopy. For Cu-doped sample, EPR spectra obtained....
