TL;DR: In this article, a hybrid mesoporous material containing etenylene in a two-dimensional, hexagonally arranged mesopore silicate framework with long-range symmetry is successfully synthesized.
Abstract: A hybrid mesoporous material containing etenylene in a two-dimensional, hexagonally arranged mesoporous silicate framework with long-range symmetry is successfully synthesized. Quantitative analysis of the reactive etenylene groups within the silicate framework indicates that approximately 30% of the etenylene is exposed at the surface and is available for further modification.

TL;DR: In this article, Fe, V, or Cu oxide was mixed in mesoporous Nb2O5, at a few atom percent, and their extremely high dispersion was confirmed by elemental analysis in about 5-nm spots using TEM-EDS.
Abstract: Fe, V, or Cu oxide was mixed in mesoporous Nb2O5, at a few atom percent, and their extremely high dispersion was confirmed by elemental analysis in about 5-nm spots using TEM–EDS. These mesoporous Nb2O5 showed characteristic selectivity for cyclohexene oxidation depending on the kind of the doped metal oxide.

TL;DR: An ordered 2D-hexagonal mesoporous Nb and Ta (Nb:Ta=l:l) mixed oxide was successfully crystallized in this paper by re-filling a templating material to the mesopores before crystallization.
Abstract: An ordered 2D-hexagonal mesoporous Nb and Ta (Nb:Ta=l:l) mixed oxide was successfully crystallized A new strategy for preserving mesoporous structure after the crystallization of the walls was performed by re-filling a templating material to the mesopores before crystallization for suppressing the destruction of mesoporous structure Transmission electron microscopy and electron diffraction analyses revealed the formation of crystallized mesoporous NbTa mixed oxide with single crystal phases in periodical mesoporous structure (denoted NbTa-TIT-2) at ca 100-nm range
