Mechanochemical Esterification Of Cellulose Nanofibers Lyophilized From Eutectic Water–Tert-Butanol Mixtures, Miran Mavlan, Taehoo Chang, Rudan Feng, Jake R. Wilkinson, Robert J. Nicholas, Nosa B. Idahagbon, Jeffrey Youngblood, Alexander Wei

Department of Chemistry Faculty Publications

Freeze-dried CNFs can be modified by mechanochemical (MC) processes with minimal use of auxiliary solvents, however aggregation of nanofibers during lyophilization compromises their granularity and reaction efficiency. Adding 10 wt% tert-butanol (TBA) to aqueous slurries of wood-derived CNF creates a eutectic mixture that reduces hornification during lyophilization, resulting in well-formed aerogels with minimal shrinkage in volume. CNFs lyophilized from mixtures containing at least 10 wt% TBA exhibit an order of magnitude increase in specific surface area relative to CNFs freeze-dried from water alone. The amount of TBA and input energy needed for lyophilization can be reduced considerably by dewatering …

#Hashtag Social Media Experiences: Building Positive Patron–Library Relationships, Alla Kushniryk, Stanislav Orlov Aug 2023

#Hashtag Social Media Experiences: Building Positive Patron–Library Relationships, Alla Kushniryk, Stanislav Orlov

Proceedings of the IATUL Conferences

The ubiquitous presence of social media has changed the way libraries communicate with their patrons. Academic libraries usually employ social media to provide instant feedback to queries and promote library services to students and faculty. However, using these tools solely for such purposes means not fully utilizing their potential. Properly applied, social media can help build and maintain positive relationships between libraries and communities they serve. Social media experts (e.g.: Quesenberry, 2021) argue that in order to build these relationships, an organization should take a “bottom up” approach to social media by engaging with patrons through social media listening and …
