In our work, the influence of coordination environment Ca atom states in biomimetic mineralizing composite dental materials integrated with tissue was investigated. Biomimetic composites as well natural samples were investigated using synchrotron X-ray absorption near edge structure (XANES) spectroscopy. Energy studies revealed a number important features related to different type calcium envir...

Local drug delivery systems are an effective approach in the treatment of purulent–septic inflammation bone tissue. Chemically bonded multiphase ceramics based on calcium-deficient carbonate-substituted hydroxyapatite combine resorbability, osteoconductivity, and possibility volumetric incorporation antibiotics. Macroporosity is regulated by concentration polyethylene glycol granules introduced...

Orthopedic bone graft infections are major complications in today’s medicine, and the demand for antibacterial treatments is expanding because of spread antibiotic resistance. Various compositions hydroxyapatite (HAp) which Calcium (Ca2+) ions substituted with Cerium (Ce3+) Magnesium (Mg2+) herein proposed as biomaterials hard tissue implants. This approach gained popularity recent years and, p...

This study focuses on the modification of natural hydroxyapatite (HAp) derived from clamshell by impregnation with palladium (Pd) at different pH in wet precipitation method to produce photoactive green materials for degradation synthetic dyes. It was found that, 10, Pd has been successfully impregnated into HAp lattice Ca/P ratio 1.77 and particle distribution size range 40?470 nm. The resulte...

interest in agrochemicals and drugs. Aryl group substituted pyrazoles and imidazoles, in particular, have been studied because their biological activities are strongly dependent on their substituents on the pyrazole ring system. 1,5-Diaryl substituted pyrazole (SR141716A, 1), which has a hydrazide group on the 3-position of the pyrazole ring, has recently been synthesized and identified as the ...

The normal intersurface forces between nanosized probe tips functionalized with COO(-)-terminated alkanethiol self-assembling monolayers and dense, polycrystalline silicon-substituted synthetic hydroxyapatite (SiHA) and phase pure hydroxyapatite (HA) were measured via a nanomechanical technique called chemically specific high-resolution force spectroscopy. A significantly larger van der Waals i...

Titanium is widely used as material for permanent implants in orthopedic and dental applications. It is well known that Ti shows a mechanically stable interface towards bone (osseointegration). The good biological properties are due to the beneficial properties of the native oxide (TiO2) that forms on Ti when exposed to oxygen. The native titanium oxide on Ti is usually amorphous and very thin,...
