Styrene and polystyrene are two important organic compounds with a wide range of applications. The key difference between styrene and polystyrene is that it is the polymerization of styrene that forms polystyrene, a synthetic thermoplastic elastomer. Styrene is chemically called vinyl benzene and is among one of the oldest known vinyl compounds in the world. This aromaticcompound was first isol...

Polymeric Nanoneedle Arrays In article number 2104828, Yaping Chen, Nicolas H. Voelcker, Roey Elnathan, and co-workers demonstrate the fabrication of relatively low-cost high throughput polymeric nanoneedles from cell culture polystyrene. The with precise geometry are imprinted directly on polystyrene petri dish via nanoimprint lithography. arrays can precisely manipulate cellular processes med...

The structural evolution of colloidal crystals made of polystyrene hard spheres has been studied in situ upon incremental heating of a crystal in a temperature range below and above the glass transition temperature of polystyrene. Thin films of colloidal crystals having different particle sizes were studied in transmission geometry using a high-resolution small-angle X-ray scattering setup at t...

The asymmetric transfer hydrogenation of imines was performed with the use of a polymer-immobilized chiral catalyst. The chiral catalyst, prepared from crosslinked polystyrene-immobilized chiral 1,2-diamine monosulfonamide, was effective in the asymmetric transfer hydrogenation of N-benzyl imines in CH(2)Cl(2) to give a chiral amine in high yield and good enantioselectivity. Furthermore, an amp...
