This section contains details regarding the preparation of catalyst and membranes and further details on the experimental setup (including two photographs of the XRD-CT experimental setup), a comment relating to an artefact present within this XRD-CT, normalised summed intensity changes (as a companion to Figure 2), XRD-CT data focusing on the BCFZ membrane, a diffraction pattern to illustrate ...

Rhombohedral-cubic transformation in Bi2Te3 doped-Pb1-xGexTe alloys is presented. Samples of Bi2Te3 doped Pb1-xGexTe were prepared by powder metallurgy approach. These powder samples were examined by high-temperature XRD and SEM/EDS. A bulk (pressed powder) cylindrical specimen was used for dilatometery characterizations. According to the XRD examinations it seems that upon increasing the tempe...

Mucoadhesive polymeric (HPMC) suspension of Ciprofloxacin was prepared by ultrasonication and optimised with the aim to develop an oral controlled release gastroretentive dosage form. The qualitative analysis of the formulation was performed by Fourier Transform Infrared Spectroscopy (FTIR), Raman Spectroscopy, X-ray powder diffraction (XRD) and Scanning electron microscopy (SEM). FTIR (400 cm ...

A new composite poly(caprolactone) (PCL) and poly(acrylic acid) (PAA) (PCL:PAA 1:5) scaffold was synthesized via dispersion of PCL particles into a PAA network. Silica microspheres (Si) (2–12 μm) were then prepared by a lyophilized micro-emulsion/sol-gel (Emugel) system using varying weight ratios. The model drug ciprofloxacin (CFX) was used for in situ incorporation into the scaffold. The phys...

Cellulose-silica composite fiber samples have been successfully synthesized using cellulose solution, tetraethoxysilane, and NH3•H2O in ethanol/water mixed solvents at room temperature for 24 h. The cellulose solution was previously prepared by the dissolution of microcrystalline cellulose in a solvent mixture of N,N-dimethylacetamide (DMAc)/lithium chloride (LiCl). The effect of the tetraethox...

Multiferroic bismuth ferrite (BiFeO(3)) nanotubes have been synthesized using a modified template methodology and characterized by a number of techniques, including XRD, SEM, TEM, HRTEM as well as EDX and SAED.

we have used lithium aluminum hydroxide reducing method of silver nitrate to prepare heterogeneous silver-silica nanocomposite particles with thiol and amino groups serving to bind the ag nanoparticles to the surfaces of the sio2 nanoparticles. we examined products of these reductions using ftir, sem, xrd and uv-vis. spectroscopy. the sio2 nanoparticles had diameters ranging from 70 to 90 nm; t...

Magnetic data is useful in both hydrocarbon exploration and mining exploration. In hydrocarbon exploration, aeromagnetic data is an effective method for locating strike-slip faulting in magnetic basement. Also, high resolution surveys enhance delineation of both subtle basement features and intrasedimentary sources. In fact, magnetic methods has evolved from its sole use for mapping basement st...
