Microwave-assisted foaming of expandable polystyrene beads

Journal of Cellular Plastics, 2011
A novel method for obtaining polystyrene foam, which uses microwave as the source of energy for expansion process, is developed. In this article, a method to disperse target expansion agent using two-stage bulk polymerization and free radical suspension polymerization of styrene is described. Current and proposed research uses environmentally friendly

Isolation of Polystyrene Bead-Induced Phagosomes for Western Blotting

2023
The engulfment of "self" and "non-self" particles by immune and non-immune cells is crucial for maintaining homeostasis and combatting infection. Engulfed particles are contained within vesicles termed phagosomes that undergo dynamic fusion and fission events, which ultimately results in the formation of phagolysosomes that degrade the internalized ...

Bead‐to‐fiber transition in electrospun polystyrene

Journal of Applied Polymer Science, 2007
AbstractThe morphological transition, namely bead‐to‐fiber transition, of electrospun polymer was examined for polystyrene, with its molecular weight ranging from 19,300 to 1,877,000 g/mol. Tetrahydrofuran and N,N‐dimethylformamide were used as solvents to examine the effects of solvent properties on the morphological variations.

Detergent removal by non-polar polystyrene beads

European Biophysics Journal, 1998
Detergent removal from lipid-protein-detergent micellar solutions is the most successful strategy for reconstitution of integral membrane proteins into proteoliposomes or into two-dimensional crystals. This review establishes the potential of polystyrene beads as a simple alternative to other conventional detergent removing strategies such as dialysis,

Self‐extinguishing polystyrene foaming‐in‐place beads

Journal of Applied Polymer Science, 1964
AbstractThe preparation of practical self‐extinguishing polystyrene foaming‐in‐place compositions by suspension polymerization is described. The halogen necessary for self‐extinguishing characteristics is incorporated by chain transfer. The synergistic effect of organic peroxides decreases drastically the amount of halogen necessary.

Antimicrobial N-brominated hydantoin and uracil grafted polystyrene beads

Journal of Controlled Release, 2015
Hydantoin-N-halamine derivatives conjugated on polystyrene beads are promising disinfectants with broad antimicrobial activity affected by the gradual release of oxidizing halogen in water. The objective of this work was to identify and test of hydantoin-like molecules possessing urea moiety, which may provide N-haloamines releasing oxidizing halogens ...

Model‐filled polymers. II. Stability of polystyrene beads in a polystyrene matrix

Journal of Polymer Science Part B: Polymer Physics, 1990
AbstractThermomechanical degradation, as a result of mixing at 175°C during the preparation of polystyrene composites containing monodisperse (0.45μm) crosslinked polystyrene beads, often leads to a uniform decrease in rheological properties on increasing the concentration or on reducing the crosslink density of the beads.

Fully automated immunoassay for detection of prostate-specific antigen using nano-magnetic beads and micro-polystyrene bead composites, ‘Beads on Beads’

Analytica Chimica Acta, 2007
Magnetic beads have served as a conventional bioassay platform in biotechnology. In this study, a fully automated immunoassay was performed using novel nano- and microbead-composites constructed by assembling nano-magnetic beads onto polystyrene microbeads, designated 'Beads on Beads'.
