Infrared spectra of a number of evolved O-rich stars have been obtained with the Short and Long Wavelength spectrometers on board the Infrared Space Observatory. The very broad wavelength coverage (2.4–197μm) obtained by combining observations made with the two spectrometers includes practically all of the flux emitted by the sources, and allows us to determine the emission and absorption featu...

A synthesis route to a hierarchically meso-/microporous BEA zeolite has been developed with a cyclic diammonium as a structure-directing agent (SDA), which leads to pseudomorphic crystallization of the zeolite by suppressing the mobility of silicates during crystallization.

Using a one-pot approach employing true liquid crystal templating on neutral surfactants and simple metal salt precursors, mesostructured, mesoporous silicates have been prepared in which bimetallic nanoparticles are deposited; magnetic properties of PtCo systems so prepared are evaluated.

Cytochrome c and xylanase were adsorbed onto two mesoporous materials, SBA-15 (a pure silicate) and MSE (an organosilicate), with very similar physical properties but differing chemical compositions. A methodical order was developed whereby the influences of surface area, pore size, extent of order, particle size, surface potentials, isoelectric points, pH, and ionic strength on immobilization ...
