This case study describes the first use of a novel nanosynthetic bone graft, OssDsign™ Catalyst, in Spinal fusion patient. new graft consists nanoscale calcium phosphate containing silicate substitution (5.8wt% silicon) which has been shown to be capable regenerating via endochondral ossification route challenging animal models [1,2], resulting high rates at very early timepoints comparable exi...

The B3LYP/6-31++G** density functional calculations were used to obtain minimum geometries and interaction energies between the molecular hydrogen and nanostructures of fullerenes, C20 (cage), C20 (bowl), C19Si (bowl, penta), C19Si (bowl, hexa). The H2 molecule is set as adsorbed in the distance of 3Å at vertical position from surface above the pentagonal and hexagonal sites of nanostructures. ...

In this study, as much as 10 and 15 wt.% nanosized silicon and carbon (Si+C) were reacted with (Mg+2B) at 650°C and 850°C, respectively, for 1 hour. The phase formation, surface morphology and superconducting properties of these samples were evaluated. The relative peak intensity as calculated from the XRD patterns indicates the formation of large Mg2Si volume fraction at low sintering temperat...

Incorporating trace elements into apatite coatings may permit the combination of several pharmaceutical effects due to the different ions. In this study, strontium, silicon, and fluoride ions have been incorporated into apatite coatings through a biomineralization method, which mimics an in vitro mineralization process. The surface composition was tested with X-ray diffraction and X-ray photoel...

Organosilanes range among the most important products in chemical industries. Unfortunately, their bulk production starting from silicon oxides has a substantial ecological footprint due to immense energy consumption and numerous hazardous by-products imposed by redox cycling between Si(0) Si(IV). Herein, we report first redox-neutral, one-pot silicon−carbon bond formation silica gel combining ...

A new potential model system for silicon monoxide (SiO) is synthesized by the interlinkage of an unsaturated cluster (siliconoid) with a polyhedral silsequioxane cage. Two derivatives variable linker size are obtained corner-capping reaction Ph7T7(ONa)3 trichlorosilane featuring remote benzylic chloride functionality and subsequent nucleophilic substitution latter anionic hexasilabenzpolarene-t...

This thesis is mainly focused on the development of new palladium catalyzed transformations using so-called “pincer” complexes. These complexes were applied as catalysts in two important areas of organometallic chemistry: substitution of propargylic substrates by dimetallic reagents; and allylation of aldehydes and imines by allylstannanes. In addition, this thesis includes studies on Lewis aci...
