TEM analysis of mesoporous materials is generally undertaken to give qualitative results. Accurate quantitative analysis is demonstrated in this study. A systematic image analysis of a powder form of a hexagonal mesoporous material known as KIT-6 is conducted using a transmission electron microscope (TEM). Three types of image contrast typically appear in this material (a hexagonal honeycomb st...

Mesoporous zinc germanium oxynitride was synthesized by a template-free method at high temperature. Through optimizing redox potentials as well as improving crystallinity, this material showed enhanced activity in CO(2) photoreduction.

A novel sulfur nanocomposite was fabricated based on graphitic mesoporous carbon.The graphitic mesoporous carbon was synthesized using sucrose as carbon precursor, nano CaCO3 as a hard template and nickel nitrate as graphitization catalyst. The structural properties of the prepared material were characterized using powder X-Ray Diffraction (XRD), N2-adsorption/de...

A hybrid nanoscopic capped mesoporous material, that is selectively opened in the presence of nerve agent simulants, has been prepared and used as a probe for the chromo-fluorogenic detection of these chemicals.

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...

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.

A molecular gate attached on the pore outlet of a mesoporous material, which is opened and closed by redox system of thiol groups, effectively switched the progress of a catalytic reaction promoted by the acidic site in the pore void.

Fe and Ni doped mesoporous Co3O4 (mCo3O4) catalysts were prepared and investigated for electrochemical oxygen evolution. The incorporation of Fe into mCo3O4 (Fe-mCo3O4) results in unusual synergistic effects via destruction of the bulk mesoporous structure and formation of slit-like pores. The Fe-mCo3O4 composite displayed a significantly enhanced catalytic activity for oxygen evolution.

A rapid and facile synthesis of cubic MCM-48 mesoporous material based on the modification of Stöber synthesis in as little time as 30 minutes at room temperature is reported in this communication.

This in vitro study reports on the enhanced release of the hydrophobic drug itraconazole from the ordered mesoporous SBA-15 silica material and on the existence of a critical mesopore diameter for enhancing release.
