There is an ongoing profound shift in using glass as a primarily passive material to one that instills active properties. We believe and demonstrate that bioactive glasses (BGs) and glass-ceramics (BGCs) as functional biomaterials for cancer therapy can transform the world of healthcare in the 21st century. Melt/gel-derived BGs and BGCs can carry m...

SiOC-based nanocomposites are new materials with excellent mechanical properties at high temperatures. here in SiOC-based macro/nanocomposites were fabricated through polymer-derived ceramic method (PDC) in which polydimethylsiloxane PDMS (containing fillers) was heat-treated in Ar atmosphere to yield a micro-porous SiOC matrix. The macrocomposite...

Silicon oxycarbide (SiOC) materials derived from silicone attracted great attention for their superior high-temperature behavior. In the present study, Si(Ti)OC and Si(Ti,Al)OC nanocomposites, in which alkoxide precursors were used with the main silicone precursor, have been compared with SiOC material. Although in SiOC, C was bonded with Si in a c...

The graphene oxide -TiO2 (GO-TiO2) and pre-reduced graphene oxide -TiO2 (rGO-TiO2) nanocomposites were fabricated successfully by hydrothermal method. The microstructure of synthesized nanocomposites was investigated using field emission scanning electron microscopy (FESEM) equipped with energy dispersive spectroscopy (EDS) analysis. Moreover, galv...

In the present study, a bioactive silicate-phosphate glass-ceramic scaffold was fabricated via the polymer-derived ceramics (PDC) method. K2HPO4 phosphate salt was used as the P2O5 precursor in this method. The effect of K2HPO4 wt% and heat treatment temperatures (900–1100 °C) was evaluated. It was observed that although increasing the wt% of K2HPO...

Rare earth (e.g., Eu, Er, Yb, Tm) doped Y2O3 nanocrystals are promising fluorescent bioimaging agents which can overcome well known problems of currently used organic dyes like photobleaching, phototoxicity, and light scattering. Furthermore, the alternative quantum dots (QDs) composed of heavy metals (e.g., CdSe) possess inherently low biocompatib...

Thermoelectric (TE) materials are capable of interconverting between heat and power. Therefore they are deemed to be promising materials for generation of power via harvesting energy from waste-heat, or alternatively, by the application of a small DC voltage modulate the temperature of a give surface. In this respect I have been developing TE materials from low temperature application materials to mid- and high-temperature applicable materials. The compositions are different that is due to the gap energies, or activation energy, that is needed to overcome vary with respect to materials composition. A very important aspect of TE materials research is to fabricate materials with high purity, high reproducibility and that the method is scalable and economical (i.e. energy and resource effective). Many of the strategies used for TE materials research fail in providing large quantity of reliable materials with more energy and resource effective way. We try to address this gap by using a diverse library of chemical strategies, offering chemical fabrication routes for a variety of TE materials. These materials consist of very fine particle, or nano-particles, due to the chemical processes used as well as other mild processing conditions. It is crucial to maintain the nano size of the grains even after the compaction. Therefore SPS technique which has short and exposure time to high temperatures and pressures is used to develop routes for the consolidation of these materials. As there was no prior art for the consolidation of these nano powders we have done extensive work to develop optimised conditions for SPS compaction for a wide range of TE nano materials developed in our lab.
