For a subtle change in the N-alkyl group of the tridentate ancillary ligand, bis(2-pyridylmethyl)alkylamine (where the alkyl group = methyl (bpma) or ethyl (bpea)), completely different products are formed under similar reaction (in methanol) as well as crystallization conditions (in water). One containing coordinated water molecules is the 3D supramolecular assembly of a tetrameric synthon com...

Meloxicam (MLX) is non-steroidal anti -inflammatory, poorly water soluble, highly permeable drug and the rate of its oral absorption often controlled by dissolution in gastrointestinal tract. Solid dispersion (SD) an effective technique for enhancing solubility such drug.
 The present study aims to enhance MLX SD solvent evaporation method using sodium alginate (SA), hyaluronic acid (HA), ...

?-Zn4Sb3 is a cheap nontoxic high-performance thermoelectric material, which unfortunately suffers from stability issues because of zinc migration in thermal and electrical gradients. Here, the properties mixed with varying sizes weight percentages TiO2 nanoparticles are investigated. Furthermore, pressed ?-Zn4Sb3-TiO2 nanocomposite pellets investigated by measuring high-energy synchrotron powd...

Topical curcumin shows poor local availability because of its low aqueous solubility and inadequate tissue absorption. Curcumin nanocrystals were prepared by sonoprecipitation followed lyophilization to improve surface area solubility. The formulation was optimized the Design Experiment (DoE) approach. characterized for particle size, zeta potential, polydispersity index, scanning electron micr...

The structure of ?-Ti2O(PO4)2·2H2O was determined by the SR-PXRD method. proton conductivity chitosan/?-TiP membranes reached 4.5 × 10?3 S cm?1 at 95%-RH.

In this study, Fe(II) complexes of phenyldithiocarbamate, dimethyldithiocarbamate and imidazolyldithiocarbamate were used as single-source precursors to prepare iron sulphide nanoparticles by thermolysis in oleic acid/octadecylamine (ODA) at 180 °C. The nanoparticles were dispersed into hydroxyethyl cellulose (HEC) to prepare iron sulphide/HEC nanocomposites. Ultraviolet-Visible (UV-Vis), Photo...

Decomposition of transition-metal amidinates [M{MeC(NiPr)2} n ] [M(AMD) n ; M=MnII, FeII, CoII, NiII, n=2; CuI, n=1) induced by microwave heating in the ionic liquids (ILs) 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIm][BF4]), 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIm][PF6]), 1-butyl-3-methylimidazolium trifluoromethanesulfonate (triflate) ([BMIm][TfO]), and 1-butyl-3-methyl...

Antimony-doped lithium stuffed garnets Li(7-x)La3Zr(2-x)Sb(x)O12 (x = 0.2-1.0) prepared using a conventional solid state reaction method are characterized using Powder X-ray Diffraction (PXRD), Scanning Electron Microscopy (SEM), Energy Dispersive Analysis by X-ray (EDAX), AC Impedance spectroscopy, Magic Angle Spinning Nuclear Magnetic Resonance (MAS NMR) and Raman spectroscopic techniques. PX...

The present studies were undertaken to develop solvent-free solid dispersions (SDs) for poorly soluble anti-inflammatory drugs mefenamic acid (MA) and flufenamic acid (FFA) in order to enhance their in vitro dissolution rate and in vivo anti-inflammatory effects. The SDs of MA and FFA were prepared using microwaves irradiation (MW) technique. Different carriers such as Pluronic F127® (PL), Eudr...
