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...

Introduction Since their discovery polyhedral oligosilsesquioxanes (POSS) have found an ever increasing number of applications in material science, catalysis, as building blocks for dendrimers and only recently biomedical use (e.g. as drug carrier systems) were reported as well. In the last two years studies of silsesquioxane based contrast agents (CA) for MRI were published [1,2] in which the ...

In the present work, potential of polyPOSS-imide membranes designed for purification H2 from a coke gas (utilized in steelmaking industry) is investigated. Aiming at upscaling membrane fabrication, tubular single-channel and multi-channel were prepared, using polyhedral oligomeric silsesquioxane (POSS) nanostructures 6FDA as reactive precursors. The separation performance has been investigated ...

Biodegradable elastomers are a popular choice for tissue engineering scaffolds, particularly in mechanically challenging settings (e.g. the skin). As the optimal rate of scaffold degradation depends on the tissue type to be regenerated, next-generation scaffolds must demonstrate tuneable degradation patterns. Previous investigations mainly focussed on the integration of more or less hydrolysabl...

This work shows the synthesis of a catalyst based on functionalization octaphenyl polyhedral oligomeric silsesquioxanes with sulfonic groups (H-Sulfo-POSS) and its performance in acetalization glycerol to yield biobased fuel additive.
