Crowding Effects of Polystyrene Nanoparticles on Lactate Dehydrogenase Activity in Hydra Attenuata

open access: yesJournal of Xenobiotics, 2020
Plastics pervade our environment and potentially release important quantities of plastic nanoparticles (NPs) from degradation in the environment. The purpose of this study was to examine the crowding effects of polystyrene NPs on lactate dehydrogenase ...

Nile red staining of polyethylene and polystyrene in Daphnia magna tests

open access: yesRomanian Journal of Ecology & Environmental Chemistry, 2023
Microplastics pollution represents a stringent global issue. Their accumulation in the aquatic environment remains complicated due to the abundance, distribution, and resulting environmental effects they induce.

Towards Polymeric Nanoparticles with Multiple Magnetic Patches

open access: yesNanomaterials, 2021
Fabricating future materials by self-assembly of nano-building blocks programmed to generate specific lattices is among the most challenging goals of nanotechnology and has led to the recent concept of patchy particles.

Structural investigations of poly(ethylene terephthalate)- graft-polystyrene copolymer films [PDF]

open access: yes, 2001
Structural investigations of poly(ethylene terephthalate)-graft-polystyrene (PET-g-PS) films prepared by radiation-induced grafting of styrene onto commercial poly- (ethylene terephthalate) (PET) films were carried out by FTIR, X-ray diffraction (XRD ...

Polystyrene modified by grafting [PDF]

open access: yesJournal of the Brazilian Chemical Society, 1997
Several grades of modified polystyrene were obtained through the graft polymerization of styrene in the presence of modifiers such as ethylene-vinyl acetate (EVA), low density polyethylene (PE), and polybutadiene (PB). These modifiers were used by themselves and in combination.

FRET Measurement of Polymer Response under Shear

open access: yesSensors, 2021
Polymer solutions under shear flow are often observed in manufacturing processes. Classically, polymer behavior is represented by Kuhn’s bead-spring model, in which only the elongation of polymer chains is assumed.

Polystyrene Magadiite Nanocomposites [PDF]

open access: yes, 2004
An organically modified magadiite has been prepared and used to make a mixed intercalated-exfoliated polystyrene nanocomposite by bulk polymerization. This system gives excellent improvement in mechanical properties, but the thermogravimetric analysis ...

Heavy Metal Adsorption and Release on Polystyrene Particles at Various Salinities

open access: yesFrontiers in Marine Science, 2021
Microplastics (MPs) and heavy metals are two major types of pollutants that interact with each other, but they are poorly understood. Polystyrene (PS) is one type of MPs that is often detected in aquatic environments.

Rational design for thermochromic luminescence in amorphous polystyrene films with bis‐o‐carborane‐substituted enhanced conjugated molecule having aggregation‐induced luminochromism

open access: yesAggregate, 2021
We designed the triad molecule, bis‐o‐carborane‐substituted bis(thienylethynyl)benzene, as a filler for realizing thermochromic luminescent behaviors based on conventional polymer films, such as polystyrene.
