The mechanism of the mechanically assisted mineral carbonation of commercial olivine under the flow of a carbon dioxide (CO2)/nitrogen (N2) mixture has been elucidated by ex situ powder X-ray diffraction and Fourier-transform infrared spectroscopy. T

We evaluate the influence of the use of different titania precursors, calcination rate, and ligand addition on the morphology, texture and phase content of synthesized mesoporous titania samples, parameters which, in turn, can play a key role in tita

The fabrication of optically active heterostructures in the shape of mesostructured thin films is a highly challenging task. It requires an integrated process to allow in one-step incorporating the two-dimensional materials within the mesoporous orde
