Synthesis and Characteristics of Polystyrene Nanoparticles and Polystyrene Monolayers

open access: yes, 2018
some selected tubers; yam, cocoyam, sweet potatoes and irish potatoes and their surface, sub-surface soils were analyzed for some heavy metal levels. levels of Mn, Pb, Cr, Cd and Cu were investigated using AAS in tubers and their soil samples. The samples were digested with a mixture of nitric acid, sulphuric acid and perchloric acid (5:5:1 v/v).

Behavior and Bio-Interactions of Anthropogenic Particles in Marine Environment for a More Realistic Ecological Risk Assessment

open access: yesFrontiers in Environmental Science, 2020
Owing to production, usage, and disposal of nano-enabled products as well as fragmentation of bulk materials, anthropogenic nanoscale particles (NPs) can enter the natural environment and through different compartments (air, soil, and water) end up into ...

Toxicity and Functional Tissue Responses of Two Freshwater Fish after Exposure to Polystyrene Microplastics

open access: yesToxics, 2021
Microplastics (MPs)’ ingestion has been demonstrated in several aquatic organisms. This process may facilitate the hydrophobic waterborne pollutants or chemical additives transfer to biota.

Capillary wave dynamics on supported viscoelastic films: Single and double layers

open access: yes, 2006
We study the capillary wave dynamics of a single viscoelastic supported film and of a double layer of immiscible viscoelastic supported films. Using both simple scaling arguments and a continuum hydrodynamic theory, we investigate the effects of ...

Isolation and identification of polystyrene degrading bacteria from zophobas morio’s gut [PDF]

open access: yes, 2015
Polystyrene (PS) and expanded polystyrene (EPS) are commodity plastics widely used in many industries. The increase of PS in the environment causes ecological threats.

Engineering the Hierarchical Porosity of Granular Hydrogel Scaffolds Using Porous Microgels to Improve Cell Recruitment and Tissue Integration

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
By fabricating and covalently assembling gelatin methacryloyl (GelMA) porous microgels, a new class of granular hydrogel scaffolds with hierarchical porosity is developed. These scaffolds have a significantly higher void fraction than their counterparts made up of nonporous microgels, enhancing cell recruitment and tissue integration. This research may

Electronic excitation produced by proton moving inside polystyrene using Drude model

open access: yesمجلة علوم ذي قار, 2019
The electronic response of target is characterized by its energy-loss function (ELF) , which it described by several models that fit the available experimental data (at zero momentum transfer), but use different approaches to obtain the Bethe surface so

Variable Fitness Response of Two Rotifer Species Exposed to Microplastics Particles: The Role of Food Quantity and Quality

open access: yesToxics, 2021
Plastic pollution is an increasing environmental problem, but a comprehensive understanding of its effect in the environment is still missing. The wide variety of size, shape, and polymer composition of plastics impedes an adequate risk assessment.
