We implemented research-based learning (RBL) as an alternative to traditional frontal classroom lectures and laboratory sessions to impart knowledge on the emerging topic of microplastics in soil to students. The RBL module aimed at studying how microplastics (MPs) affect soil processes. We designed low-cost, small-scale and simple experiments for…

To increase interest in chemical engineering and introduce non-traditional chemical engineering fields to high school women, an outreach activity focused on the biomedical applications of polymers was developed. Surveys given to students before and after the activity demonstrated greater agreement with the statements "I am interested in…

Due to the COVID-19 pandemic, many universities have switched to online learning platforms, which inhibits engineering students from completing formative hands-on experiments. To address this, we developed at-home experiments for an undergraduate biomaterials course. These inquiry-based learning experiments were well received by students and…

We designed a hands-on laboratory exercise to demonstrate why injecting an aqueous polymer solution into an oil reservoir (commonly known as "polymer flooding") enhances oil production. Students are split into three groups of two to three. Each group is assigned to a packed Hele-Shaw cell pre-saturated with oil, our laboratory model of…

Prior to the recycling process, raising awareness of plastic waste impact, e.g., polluting oceans worldwide, is undoubtedly a first attempt to tackle this pandemic environmental issue. With this in mind, the presented practical session is an effort to entice an interdisciplinary audience of science undergraduates toward a sustainable future. The…

A method to fabricate microfluidic devices and an experimental protocol to model intravascular gas embolism for undergraduate laboratories are presented. The fabrication process details how to produce masters on glass slides; these masters serve as molds to pattern channels in an elastomeric polymer that can be adhered to a substrate, resulting in…

This lab experiment illustrates the use of differential scanning calorimetry (DSC) and thermal gravimetric analysis (TGA) in the measurement of polymer properties. A total of seven exercises are described. These are dry exercises: students interpret previously recorded scans. They do not perform the experiments. DSC was used to determine the…
