Considerable research efforts have been used in the development of floating drug delivery system including gas generation system, swelling systems and low density systems. In the development of low density systems the porous carriers are used because of its characteristics such as stable uniform porous structure, high surface area, tunable pore size and well-defined surface properties. This rev...

This paper presents results of porous Sic characterization using photoluminescence, Raman scattering and Atomic Force Microscopy. A comparative optical spectroscopy study on bulk Sic and porous Sic layers has shown a number of new features specific to nano-crystallite materials. The role of these effects on optical spectroscopy data in porous Sic accessed by photoluminescence and Raman scatteri...

In fields of materials science and chemistry, ionic-type porous materials attract increasing attention due to significant ion-exchanging capacity for accessing diversified applications. Facing the fact that porous cationic materials with robust and stable frameworks are very rare, novel tactics that can create new type members are highly desired. Here we report the first family of polyhedral ol...

Tritium behavior in plasma-facing components (PFCs) of future tokamak reactors such as ITER is an essential factor in evaluating and choosing the ideal plasma-facing materials (PFMs). One important parameter that in ̄uences tritium buildup and release in candidate materials is the e€ect of material porosity on tritium di€usion and retention. Di€usion in porous materials, for example, consists of...
