Adopting GenAI in Higher Education, a Faculty Workshop Addressing Beliefs and Agency

This paper reports the results of an intensive faculty-development workshop on generative AI (GenAI), delivered to a community of university teachers with an established practice of peer observation and reflective teaching within the Mentor Project. Adopting a pre-post, single-group design (N = 26 at pre-test, N = 25 at post-test) and drawing on a four-dimension model of teacher engagement with GenAI (Perceptions, Acceptance, Knowledge, Practices), the study examines whether a short, intensiv...

Chemoselective depolymerization of polyurethane via solvent-engineered glycolysis

The chemical upcycling of polyurethane (PU) into virgin-quality feedstocks is hindered by toxic toluene diamine (TDA) formation during high-temperature glycolysis. Decoupling selective urethane cleavage from secondary thermolytic pathways remains a central engineering challenge. Here, we present a chemoselective depolymerization strategy utilizing solvent-system synergy. Systematic evaluation of binary-glycol environments identifies a 6 : 4 monoethylene-to-diethylene glycol ratio that balance...

Ionolysis of flexible polyurethane waste using ionic liquids for efficient and sustainable polyol recovery

: Chemical recycling of polyurethane waste is essential for advancing circular economy objectives, as current technologies struggle to efficiently recover monomeric building blocks. Here, we present an efficient ionolysis-based recycling approach using 1-ethyl-3-methylimidazolium bromide (EMIM-Br) as bifunctional solvent-catalyst. Under mild conditions (150°C, 1 MPa), the ionic liquid disrupts hydrogen bonding and selectively cleaves urethane linkages, yielding virgin-like polyols. Polyols ar...
