Novel composite from chitosan and a metal-organic framework for removal of tartrazine dye from aqueous solutions; adsorption isotherm, kinetic, and optimization using Box-Benkhen design.

Cosmetics, textiles, foodstuffs, and medicines frequently contain the yellow dye tartrazine. It has carcinogenic properties and can trigger allergies. In this study, a unique NH-MIL-101(Cr)/chitosan composite (MIL/chitosan composite) was created using a hydrothermal process.

Phosphorus-substitution effect on the phase stabilization, electrical and spectroscopic properties of LAMOX-based electrolyte for solid oxide fuel cells.

A series of P - doped LaMoO phases with different concentrations of P were prepared using conventional solid-state reactions. The formation of phase-pure P-doped LaMoO has been monitored by powder X-ray diffraction, thermal analysis, conductivity measurements, Raman, and FT-IR absorption techniques. The structure and lattice parameters of LaMoPO are obtained from Rietveld refinement.

Crystal Chemistry, Optic and Magnetic Characterizations of a New Copper Based Material Templated by Hexahydrodiazepine.

Crystals of the new organic-inorganic material (DAP-H2)[CuBr] (); (DAP = hexahydrodiazepine (CHN)) were successfully synthesized by slow evaporation and characterized by single-crystal X-ray diffraction, infrared spectroscopy, thermal analysis, UV-Vis-NIR diffuse reflectance spectroscopy, and magnetic measurements. X-ray investigation demonstrates that crystallizes in the monoclinic space group 2/. The supramolecular crystal structure of is guided by several types of hydrogen bonding which connect anions and cations together into a three-dimensional network.

Enhanced Adsorption and Evaluation of Tetracycline Removal in an Aquatic System by Modified Silica Nanotubes.

In the present study, a nanocomposite adsorbent based on mesoporous silica nanotubes (MSNTs) loaded with 3-aminopropyltriethoxysilane (3-APTES@MSNTs) was synthesized. The nanocomposite was employed as an effective adsorbent for the adsorption of tetracycline (TC) antibiotics from aqueous media. It has an 848.

Mechanochemical Promoted Heterocycles: A Solvent-free Route to Triazole Carbohydrates as Glycogen Phosphorylase Inhibitors.

Aims: This study aimed to recommend a novel way for the preparation of carbohydrates containing triazole derivatives.

Background: Triazoles containing derivatives have numerous biological activities. Ball milling is a fast, modest, green process with massive potential.

Pickering Emulsions of Fluorinated TiO: A New Route for Intensification of Photocatalytic Degradation of Nitrobenzene.

Fluorination of the TiO surface has been often reported as a tool to increase the photocatalytic efficiency due to the beneficial effects in terms of production of oxidizing radicals. Moreover, it is shown that the unique amphiphilic properties of the fluorinated TiO (TiO-F) surface allow one to use this material as a stabilizer for the formulation of Pickering emulsions of poorly soluble pollutants such as nitrobenzene (NB) in water. The emulsions have been characterized in terms of size of the droplets, type of emulsion, possibility of phase inversion, contact angle measurements, and optical microscopy.

Photocatalytic Degradation Enhancement in Pickering Emulsions Stabilized by Solid Particles of Bare TiO.

Pickering emulsions provide a new way to enhance the efficiency of photocatalytic degradation of water-insoluble pollutants. Indeed, the semiconductor solid particles dually act as the photocatalyst and stabilizer of the emulsion droplets whose size dramatically affects the photocatalytic reaction. The present work aims at the validation of this concept by using bare TiO without any surface modification.

TiO-PANI/Cork composite: A new floating photocatalyst for the treatment of organic pollutants under sunlight irradiation.

A novel photocatalyst based on TiO-PANI composite supported on small pieces of cork has been reported. It was prepared by simple impregnation method of the polyaniline (PANI)-modified TiO on cork. The TiO-PANI/Cork catalyst shows the unique feature of floating on the water surface.
