The surfaces of hydoxyapatite ceramics were modified by the precipitation of octacalcium phosphate coating from aqueous solution and the biomimetic method synthesized nanohydroxyapatite coatings. Both coatings were deposited as continuous and uniform layers. It was demonstrated that the octacalcium phosphate coating was inappropriate for in-vitro osteoblast proliferation despite of good initial...

High density ceramics of the system Bi1-xLaxFeO3, 0 ≤ x ≤ 0.15, have been prepared starting from nanoparticles obtained by mechanosynthesis. The ceramics have been sintered conventionally at 850oC and by spark plasma sintering (SPS). Sintering conditions have been optimized to obtain single phase ceramics, and the microstructure of the ceramics has been compared. Ceramics prepared conventionall...

In recent years, ceramics, polymers, and composites have been used to develop biologically mechanically suitable bone scaffolds. β-tricalcium phosphate（β-TCP) is a widely bioceramic in tissue engineering. It shows excellent osteoconductivity, osteoinductivity, good biocompatibility properties, as its chemical composition similar the original structure of bone. Herein, we designed β-TCP-PLA comp...

a r t i c l e i n f o Over the past 2 years, the synthetic process of talc particles has evolved considerably, leading to an inexpensive, convenient, and rapid process that is compatible with industrial requirements. In addition to facilitate the synthetic talc preparation, the evolution of the synthesis process has led to an improved crystallographic arrangement of the talc particles in both t...

Nanoscale scientific issues have attracted an increasing amount of research interest due to their specific size-effect and novel structure-property. From macro to nano, materials present some unique chemical reactivity that bulk materials do not own. Here we introduce a facile method to generate silicate with nanoscale control based on the establishment of a confined space between a meso/nanosc...

hotostructurable glass–ceramics are suitable for 3-dimensional microfabrication and, in some instances, can be used as an alternative material o silicon in the microfabrication of micro-electro-mechanical-system (MEMS) devices. Foturan® is a photosensitive lithium–aluminium–silicate lass that can be structured by an exposure to UV light, followed by a thermal treatment and an etching step. In t...

The structural behavior of cations in multicomponent oxide glasses cannot be described within a random network model, due to the presence cation clusters that provide original properties. These clustering processes are even observed for may occur at percent level concentration, which makes it all more spectacular. In particular, and chemical characteristics Zr 4+ - Fe 2+ /Fe 3+ -based (alumino)...

The cooling of a melt corresponding to the eutectic between wollastonite (CaSiO3) and diopside (CaMgSi2O6) determines synthesis an interesting example alkali-free bioactive glass, easily converted into glass-ceramics featuring two silicate phases, coupled also with åkermanite (Ca2MgSi2O7), by sinter-crystallization fine glass powders at 1000°C. fabrication scaffolds digital light processing sus...
