Avoiding Aggregation During Drying And Rehydration Of Nanocellulose, Evelyn Fairman
Avoiding Aggregation During Drying And Rehydration Of Nanocellulose, Evelyn Fairman
Honors College
Nanocellulose has attracted attention from academic researchers and industrial corporations worldwide. It is a sustainable raw material with remarkable strength and rheological properties. The industrial production of nanocellulose is an aqueous process; however, many of its valuableproperties are lost upon water removal. Indeed, once dried, nanocellulose irreversibly assembles into a plastic-like material. Currently it can betoo expensive to transport the aqueous suspensions. In order to mitigate high transportation costs, a methodmust be developed to dry and rehydrate nanocellulose whilst maintaining its nano-morphology. The current work demonstrates that the introduction of a cationic surfactant into the aqueous nanocellulose suspensionyields a chemical …

Design Focused Computer Module For Chemical Engineering Outreach, Marc Beauchemin
Honors College
The purpose of this project is to propose the use of a computer simulation to provide middle and high school students with a chemical engineering design experience. Long standing collective efforts between the University of Maine Department of Chemical and Biological Engineering and the Pulp and Paper Foundation have resulted in a variety of outreach programs aimed at students of this age. Recently, both organizations have been increasing efforts in these areas, proposing a senior design project focused on making a portable model demonstrating chemical engineering concepts. This project was examined along with other outreach efforts and teaching modules. The …
