New research reveals that PET-based glitter microplastics can actively influence biomineralisation processes in marine environments, raising fresh concerns about the long-term environmental impact of microplastic pollution on marine ecosystems. The research, led by a team from Trinity College Dublin’s School of Natural Sciences and published in the journal Environmental Sciences Europe, shows that these microplastics promote the crystallisation of calcium carbonate (CaCO₃) minerals, potentially affecting the growth and stability of marine calcifying organisms. 

Self-healing coatings are advanced materials that can repair damage, such as scratches and cracks on their own. Researchers from Waseda University have developed an efficient method for preparing self-healing films consisting of alternating layers of highly cross-linked organosiloxane and linear polydimethylsiloxane (PDMS). Their film is more durable than conventional self-healing PDMS materials, offering superior hardness and greater thermal stability while self-healing at mild temperatures, paving the way for stronger, more reliable, and easier-maintained self-healing materials.
