Polyvinyl butyral (PVB) is a high-performance thermoplastic polymer, commonly used as an interlayer material in laminated safety glass for the automotive and architectural sectors. Currently, there is no end-of-life cycle program for a substantial amount of PVB film, which mainly ends up in landfills. According to a circular approach, PVB can be revalorized after efficient separation and recovery from glass.

A mixed Bi-Zn catalyst and a 71% bio-based isocyanate are exploited at this aim through multivariate chemometric approaches, namely Design of Experiment (DoE). DoE allows us to investigate the effect of different formulation factors on selected parameters, such as the film flexibility and transparency or the gel time.

Metastatic triple-negative breast cancer (mTNBC) is characterized by an aggressive clinical course and unfavorable outcomes, despite the pharmacological treatments used. The present clinical case describes a 35-year-old woman affected by TNBC characterized by rapid and subsequent local, cutaneous and lymph node progression of the disease.
