Abstract There is a critical need to generate environmentally relevant microplastics (MPs) and nanoplastics (NPs) better investigate their behavior in laboratory settings. Environmental MPs are heterogenous size shape, unlike monodisperse uniform microspheres commonly used as surrogates. Cryogenic grinding, or cryomilling, was successfully utilized transform polystyrene (PS) bulk material into micro nano fragments. Fourier-Transform Infrared (FTIR) spectroscopy confirmed that this approach...
Abstract Background Authentic assessment and two‐stage exams have recently received attention; however, they are rarely used together. We reimagine by integrating an authentic, computer‐based into the structure of a exam in large engineering class. Purpose seek to identify ways that such extends classroom testing better align with practice examining teams negotiate uncertainty make decisions. also differing students' reactions increased during tests. Design/Method Using methodical framework...
Current research regarding microplastic (MP) fate and effects has largely focused on pristine MPs in simplified aquatic solutions. Yet, are readily transformed upon entering the environment through processes including photochemical weathering formation of eco-coronas by adsorption natural organic matter. In this work, eco-corona virgin UV-aged polystyrene (PS) polyvinyl chloride (PVC) was quantified using quartz crystal microbalance with dissipation changes surface chemistry monitored...
Aggregation behavior of ‘pristine’ ENMs in freshwater diverges from the more realistic, ‘aged’ ENMs.
