Mesoporous silicon (PSi) microcavities (MC) based on one-dimensional photonic crystals have been studied as optical sensors for relative humidity (RH). Oxidized PSi modified the structure of the MC such that the spectral position of the MC resonance peak depended on the humidity. A spectral shift of the MC resonance peak of up to 6 nm to longer wavelengths was observed as the RH increased from ...

1. Introduction Molecular dynamics under confinement is a subject of extensive scientific research. Besides fundamental interest, the understanding of the very intrinsic mechanisms of how confinements alter the fluid transport properties has an immense impact on application-oriented sciences, including life sciences in particular. Having the possibility of preparing mesoporous materials with we...

This thesis aims at the synthesis of oriented nanochannel systems for the synthesis of metallic or semiconducting nanowires. Three different synthesis strategies have been developed. First, horizontal macroto mesoporous anodic aluminum oxide (AAO) structures with individually addressable channel systems were fabricated in collaboration with the group of Dr. Anna Fontcuberta at TU München. For t...

Elaboration of new structures based on semi-conductors and conducting polymers can procure a alternative to the development various electrochemical sensors with good sensibility. The key idea this paper is develop facile technique for detection para-nitrophenol which considered as an important toxic pollutant. In context, different mesoporous silicon modified Polypyrrole (PPy) were elaborated. ...

Mesoporous calcium-silicon xerogels with a pore size of 15 nm (MCS-15) and pore volume of 1.43 cm(3)/g were synthesized by using 1,3,5-mesitylene (TMB) as the pore-expanding agent. The MCS-15 exhibited good degradability with the weight loss of 50 wt% after soaking in Tris-HCl solution for 56 days, which was higher than the 30 wt% loss shown by mesoporous calcium-silicon xerogels with a pore si...
