In recent years, several investigations of the environment-sensitive mechanical behavior of certain crystalline, nonmetallic materials and glasses have been directed toward characterizing the wear behavior of these materials under conditions of sliding and drilling in active liquid environments. Buckley,' for example, examined the change in plastic deformation and friction coefficient of single...

Tissue engineering scaffolds are highly engineered structures that accommodate cells, facilitate their expression, and resorb to facilitate regeneration of tissue. A new technique for producing controlled pore shape and pore size interconnectivity offers promise for application as a tissue engineering scaffold. Salt particles were spheroidized in a flame and sintered to provide an interconnecti...

We investigate numerically the multiple quantum (MQ) NMR dynamics in systems of nuclear spins 1/2 coupled by dipole-dipole interactions in the case of the pseudopure initial state. Simulations of the MQ NMR with real molecular structures such as six dipolar-coupled proton spins of benzene, hydroxyl proton chains in calcium hydroxyapatite, and fluorine chains in calcium fluorapatite open the way...

Abstract This study aimed to prepare a resin based dental sealant loaded with novel bioactive glass formulated from (50 wt% calcium silicate and 50 sodium silicate) different percentages of fluorapatite. Four batches were then characterized using Fourier Transform Infrared Spectroscopy analysis, X-ray powder diffraction analysis Transmission electron microscopy. Density, microhardness bioactivi...

In bone tissue engineering, ionic doping using bone-related minerals such as magnesium (Mg) or strontium (Sr) is a promising strategy to make up for the inherent disadvantages (low solubility) of various apatite-based materials (such fluorapatite (FAp) and hydroxyapatite (HA)). Therefore, some studies in recent years have tried address lack-of-methodology improve properties bioceramics field. E...
