This review article focuses on the recent applications of tris(trimethylsilyl)silane as a radical-based reagent in organic chemistry. Numerous examples of the successful use of (TMS)(3)SiH in radical reductions, hydrosilylation and consecutive radical reactions are given. The use of (TMS)(3)SiH allows reactions to be carried out under mild conditions with excellent yields of products and remark...

A moment equations method was performed to study the Reversible chain Transfer Catalyzed Polymerization (RTCP) of styrene in 80°C. To do this, a kinetic scheme containing conventional free radical polymerization reactions and equilibrium reactions of RTCP was assumed. After obtaining mass balance equations, three moment equations were defined for free and dormant radicals and dead chains. M...

The polymerization of hydrophilic monomers is reported utilizing Cu(0)-mediated living radical polymerization, SET-LRP. Highly active Cu(0) is formed in situ as a result of rapid disproportionation of [Cu(I)(Me6-Tren)Br] in serum. Disproportionation and homogenous controlled radical polymerization (PDI 1.09-1.25) are performed for the first time in blood (sheep) serum.

A dual nanocomposite hydrogel with inorganic hybrid crosslinking was fabricated through a simultaneous sol-gel technique and free radical polymerization. Due to the multi-strengthening mechanism of the dual nanocomposite, the hydrogel was super tough and strong with a compressive stress of 32.00 MPa without rupture even at 100% strain, while it exhibited excellent fatigue resistant properties.

Doxorubicin-loaded nanogels with multiresponsive properties are prepared using hyperbranched polyglycerol as a biocompatible scaffold. The nanogels are synthesized in a single step combining free-radical polymerization and a mild nanoprecipitation technique. The nanogels respond to different biological stimuli such as low pH and reductive environments, resulting in a more efficient cell prolife...
