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...
Zeolites have been investigated as sorbents of heavy metals from water. Since graphene oxide was already reported promising radionuclide sorbent, we developed composite materials containing both a synthetic zeolite (type A, P or Y) and to be multifunctional sorbents. The extension multifunctionality done by presence third component, exfoliated graphite, additional properties conductivity. changing sorption activities studied depending on its composition functional modification. composites,...
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...
Huntington's disease (HD) is an autosomal dominant affecting neurons predominantly in the striatum due to production of toxic huntingtin protein. Lowering concentration mutant a promising therapeutic approach, and suitable delivery system fascinating. Nanoparticles (NPs) minimize host immune response have no limit concerning number NPs administered. They are safe, targeted, effective for RNA therapeutics providing significant mode cross blood–brain barrier broad range clinical applications....
Microwave-accelerated ring-opening polymerization (ROP) of cyclic esters catalyzed by ionic liquid (IL) anions, intercalated into layered double hydroxides (LDHs), has been recently described as a fast and environmentally friendly synthetic way to prepare biodegradable polyester/LDH nanocomposites. However, observe this synergistic catalytic effect between microwaves IL anions achieve homogeneous structure the final polymer nanocomposite, must be efficiently inside LDH structure. Herein, we...
The gas and water vapor permeabilities of graphene-based membranes can be affected by the presence different functional groups directly bound to graphene network. In this work, one type carboxylated oxide (GO-COOH) two types synthesized i) under strong oxidative conditions from graphite (GO-1) ii) mild exfoliated (GO-2) were used as precursors self-standing prepared with thicknesses in range 12–55 μm via slow-vacuum filtration preparation method. It was observed that for all tested gases...
Laboratory synthesis of microsheets titanium dioxide from titanyl sulfate involves the use ammonia solution, whereas another inorganic base is most likely to be employed at industrial level, as a toxic agent and therefore should avoided according European Union (EU) regulations. Selected nontoxic bases such sodium, potassium, lithium hydroxides have been tested an alternative solution obtain amorphous crystalline TiO2-based microsheets. The final products obtained each step procedure...
The aim of this study was to explore the influence various n-propylamines (mono, di, and tri) tert-butylamine on properties prepared peroxo-titanates annealed TiO2. Detailed structural characterization (SEM, TEM with EDX, XRD) confirmed 2D-foil morphology TiO2 nanocrystals CHNS analysis together XPS showed presence carbon (under 1 wt%). excellent photocatalytic activity up four times higher decomposition rate constant upon UV irradiation than P25. Favourable growth crystals observed...
