INTRODUCTION Capasio is being developed as a new generation of endodontic material with potential use as a root-end filling material. The aim of this study was to compare the ability of Capasio and mineral trioxide aggregate (MTA) to penetrate human dentinal tubules and examine the interaction of Capasio and MTA with a synthetic tissue fluid (STF) and root canal walls in extracted human teeth. ...

A combination of gel-casting and polymeric foam infiltration methods is used in this study to prepare porous bodies of hydroxyapatite (HA), to provide a better control over the microstructures of samples. These scaffolds were prepared by impregnating a body of porous polyurethane foam with slurry containing HA powder, and using a percentage of solids between 40% and 50% w/v, and three different...

INTRODUCTION Bioactive endodontic sealers have been developed to improve the quality of root canal obturation. EndoSequence Bioceramic (BC) Sealer is amongst calcium silicate-based materials recently developed for permanent root canal filling. The objective of this study was to evaluate the bioactivity of BC Sealer and its micro push-out bond strength to dentin compared to AH-Plus (AH) sealer. ...

Nano sized ZnS and MnS2 were synthesized through a simple wet chemical route. In this Synthesis metal sulfides were used as the starting material and allowed to react with the transition metal source at 60°C for 75 minutes. The products were characterized by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Photoluminescence spectra (PL), Raman Spectra, Thermogravimetry analysis Diff...

Calcium carbonate nano particles were synthesized using precipitation method from cockle shells by employing chitosan as precursor. Synthesized Calcium carbonates were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), UV-Visible and FTIR Spectroscopy. The results were compared with commercial calcium carbonate nano particles. Cockle shells are the potential source...

Microscopical tests, including polarized light microscopy (PLM), phase contrast microscopy (PCM), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were used along with X-ray diffraction (XRD) in the characterization and testing of a laboratory-grade “Gooch fiber” asbestos sample. The sample was tested for possible fiber release during typical use as a substrate for ...

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 ...

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 ...

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...
