Background and Aim: Several reports have been published on the successful application of various bone substitute materials (BSM). Appropriate physiologic and histologic characteristics and reactions of these materials against host cells are critically important. In this study, the biocompatibility of a new bone substitute material has been evaluated. Methods and Materials: In this experime...

[1] A general acoustic model for a frequency sweep rod-liquid-rod interferometer applicable to high-temperature silicate liquids is presented. The wave propagations in the acoustic model are solved according to the accurate elastic wave equation and the acoustic wave equation. The solutions indicate that when a pulsed wave is sent down a buffer rod, which is partially immersed in a silicate liq...

There has always been a fascination with "impossible" compounds, ones that do not break any rules of chemical bonding or valence but whose structures are unstable and do not exist. This instability can usually be rationalized in terms of chemical or physical restrictions associated with valence electron shells, multiple bonding, oxidation states, catenation, and the inert pair effect. In the pu...

Resulting from their versatile functionality, nanomaterials with low systemic toxicity have offered high-performance diagnostic and therapeutic capabilities. Here, we designed and synthesized uniform magnesium silicate hollow spheres as high drug-loading nanocarriers for cancer therapy. Through a classical Stöber method and a hydrothermal process, well-defined MgSiO3 hollow spheres were prepare...

Considering light absorption by narrowing the band gap and gas capture by the mesostructure and basicity of material, an efficient artificial photosynthesis system was constructed based on a mesoporous ZnAl(2)O(4)-modified ZnGaNO photocatalyst.

The present work was undertaken to evaluate the feasibility of nickel (II) removal from aqueous solution by adsorption onto a biopolymer adsorbent. The adsorbent was prepared using modification of mesoporous silicate SBA-15 with alginate biopolymer (alginateSBA-15) by encapsulation method. Morphological structure of the obtained nanocomposite adsorbent was characterized by XRD, scanning electro...

For practical consideration in applying mesoporous films for sensors, it is ideal to fabricate thinner films to achieve fast transport and therefore rapid response. Here we report a new, facile method to deposit mesoporous silica films with thickness less than 100 nm through combining convective self-assembly and surfactant/silica self-assembly. Through an interfacial capillarity defined in the...

The aim of this project is to prepare various m esoporous hosts having hexagonal and cubic pore packing morphologies and improve their thermal, hydrolysis, and mechanical stabilities. Subsequently, we incorporate metal clusters and metal oxides into the pores to improve their sorption properties and to remove different types of sulphur compounds from organic liquids. Hydrolysis, thermal and hyd...
