Suspension Polymerization of Styrene Using Zinc Oxide as a Suspension Agent [PDF]
Journal of Materials Science and Engineering B, 2011 The advantage of suspension polymerization is that the polymer product can be separated easily from the mixture of reaction product, in the form of small spherical polymer solid. This method is commonly employed in the production of expanded polystyrene.

Advanced Engineering Materials, EarlyView.This study explores the discrepancies between bulk mechanics and spatial mapping in a tissue‐mimetic hydrogel model. Microplastic particles create localized stiff mechanical microenvironments that are detectable by cellular‐scale nanoindentation but leave bulk properties unchanged as measured by rheology.
