A new class of silicone monomers, providing transparent materials and imparting hydrophilic properties have been developed. These materials are incorporated into ophthalmic devices such as soft and rigid gas permeable (RGP) contact lenses. These new silicone monomers include Polyhedral Oligomeric Silsesquioxane (POSS) with two polymerizable groups and six organofunctional groups. These types of structures incorporate at least two available sites for polymerization allowing for the incorporation of the silsesquioxane cage into the backbone of a macromolecule. Additional functional sites allow the design of specific chemical features which address needed material properties.

The present invention discloses novel calibrants containing between 1 and 5 iodine atoms and methods of making them using linear polymers, hyperbranched polymers, and biological polymers (including but not limited to proteins and peptides.) Methods of using the calibrants are also disclosed, such as mass spectrometry. The novel calibrants disclosed herein have a more cost- and time-efficient synthesis than other calibrants.

A catalytic cracking process includes a step of contacting a cracking feedstock with a catalytic cracking catalyst in the presence of a radical initiator for reaction under catalytic cracking conditions. The radical initiator contains a dendritic polymer and/or a hyperbranched polymer. The dendritic polymer and the hyperbranched polymer each independently has a degree of branching of about 0.3-1, and each independently has a weight average molecular weight of greater than about 1000. The catalytic cracking process is beneficial to enhancing and accelerating the free radical cracking of petroleum hydrocarbon and promoting the regulation of cracking activity and product distribution; by using the process disclosed herein, the conversion of catalytic cracking can be improved, the yields of ethylene and propylene can be increased, and the yield of coke can be reduced.

Dendrimer-based compositions and methods are provided, that are useful for administering pharmaceutical compositions to target cells and tissues for treatment of ocular diseases including macular degeneration, diabetic retinopathy, and retinitis pigmentosa.
