DetailsReview the x-ray technique in the ” In-situ X-ray Absorption Spectroscopy of Supported Ru Catalysts in the aqueous phases’ Many of the techniques used to characterize catalysts in the presence of vapor-phase molecules are not appropriate for liquid water. Because X-ray absorption spectroscopy and H2 chemisorption are specific probes of the active transition metal, we…
DetailsIn recent years there is an increasing interest in developing new approaches to improve the efficiency of photovoltaic cells (solar cells). Silicon is the most widely used material for solar cells and is due to its abundance in nature, stability, non-toxicity and well established refining and processing technologies [1]. Even though commercial single crystalline silicon solar…
DetailsNematic liquid crystalline polymers (LCP’s) are interesting anisotropic fluids, which may have some orientational order at rest (molecules tend to align in the same direction). Those polymers may be useful to obtain oriented materials with excellent mechanical, electrical and thermal properties. Its rheological, mechanical and optical properties may be changed by the particle inclusion, depending…
