RECOMPENSE: A Student-Led Open Science Initiative for Sustainable Polystyrene Waste Upcycling in Academic Labs Plastic waste is a global challenge, with polystyrene (PS) among the least recycled polymers despite its widespread use in laboratories. Conventional recycling routes for PS remain economically and te...

♻️🔬 From lab waste to catalysts and co-created learning!

We just shared our new preprint on RECOMPENSE, a student-led open science initiative that upcycles polystyrene waste into reusable catalysts for green chemistry.

and my new view is that if an LLM can do it, it’s a task or form or piece of paperwork that doesn’t need to and shouldn’t exist.

I still have one PhD position available for Oct 2026 - see below for more details.

While a blue shift in the absorption spectra of particles with decreasing particle size is a sign of a delocalised excited state restricted in size by the volume of the particles, it is not a sign that this state necessarily only involves the inorganic core of the particles and is bulk-like. (5/N)

We also find that for most particles the optical gap is predicted to increase with decreasing particle size, even if the optical gap involves also the ligands. (4/N)
