It has been well-recognized that many natural organisms exhibit elegant hierarchical porous architectures, which endow them with very unique properties. Inspired by nature, substances that are “made porous” have been one of the most intensively investigated topics involved in the approaches to construct hierarchically dimensioned materials. Vast potential applications can be envisaged for such ...

Hierarchical self-assembled structures provide a “bottom-up” method to utilize relatively simple and low cost processes to generate nanoscale patterns (usually through amphiphilic low molecular weight surfactants or block copolymers). These self-assembled structures from block copolymers are generally driven by a combination of repulsive and attractive interactions between the block segments an...

As the scientific community develops the ability to create composites which incorporate nanoscopic filler particles, the detailed atomic arrangement and atomic interactions become significant in determining the composite properties. Nanoscopic fillers such as carbon nanotubes, polyhedral oligomeric silsesquioxane (POSS), and layered silicates have already been successfully used to improve the t...

BACKGROUND The application of nanotechnology in biology and medicine represents a significant paradigm shift in the approach to the treatment of cancer. Evidence suggests that when exposed to near-infrared radiation (NIR), carbon nanotubes (CNTs) dissipate a substantial amount of heat energy. We have developed a novel nanocomposite polymer, polyhedral oligomeric silsesquioxane poly (carbonate-u...

We herein demonstrated an approach to control the spatial distribution of components in hybrid microspheres. Hybrid core-shell structured microspheres (CSMs) prepared through co-assembly were used as starting materials, which are comprised of anthracene-ended hyperbranched poly(ether amine) (AN-hPEA) in the shell and crystallized anthracene containing polyhedral oligomer silsesquioxane (AN-POSS...

To improve the overall performance of polyurethane acrylic (PUAs) coatings applied to an iron or wood substrate, a modifier, trivinylisooctyl polyhedral oligomeric silsesquioxane (TVi7iso–POSS), was successfully synthesized by polycondensation reaction in presence organotin catalyst. TVi7iso–POSS is POSS derivative possessing three olefin and seven isooctyl bonds; its molecular structure confir...

Public open spaces (POSs) can be crucial during earthquakes, serving as essential places for recovery and mitigation. However, the ability of POSs to respond earthquakes varies based on their degree resilience. Resilience plays a significant role in ensuring effective responsiveness POSs, addition enhancing daily use normal times. By exploring examining earthquake resilience criteria that incor...

An alkyne-bearing polyhedral oligomeric silsesquioxane (POSS) core was used to prepare POSS-containing polymer hybrids using 'grafting to' or 'grafting from' strategies in combination with reversible chain transfer and click chemistry.

Here, we demonstrate the first known approach to create G1 and G2 POSS dendrimers with 9 and 65 POSS units, and 56 and 392 terminal vinyl groups from a 1 → 7 branching monomer in only one and three steps.
