Poly(alkyl acrylate)-based adhesives are used as coatings for stainless-steel filters to enhance microplastic removal efficienciesviaadsorption. 

Microplastics have been found in the most remote locations on Earth as well as in where we live, work, and play. Despite increasing research focus on microplastics, efforts to inform the public about their omnipresence have lagged. To bridge this gap between research and public knowledge, we developed a museum exhibit with interactive and informative displays that explain what microplastics are, how they are formed, where they are found, and what individuals can do about it. In a partnership between researchers at the University of Michigan (Ann Arbor) and staff at the Dossin Great Lakes Museum (Detroit), the exhibit highlights the impacts of microplastic pollution in the region. Collected survey data revealed that museum visitors were aware of microplastic pollution and are worried about it, that they felt the museum exhibit was helpful and informative, and that they are likely to take simple actions to decrease microplastic pollution. 

Abstract Access to clean water has become increasingly difficult, motivating the need for materials that can efficiently remove pollutants. Hydrogels have been explored for remediation, but they often require long times to reach high levels of adsorption. To overcome this limitation, we developed a rapid, locally formed hydrogel that adsorbs dye during gelation. These hydrogels are derived from cellulose—a renewable, nontoxic, and biodegradable resource. More specifically, we found that sulfated cellulose nanofibers or sulfated wood pulps, when mixed with a water‐soluble, cationic cellulose derivative, efficiently remove methylene blue (a cationic dye) within seconds. The maximum adsorption capacity was found to be 340 ± 40 mg methylene blue/g cellulose. As such, these localized hydrogels (and structural analogues) may be useful for remediating other pollutants.
