The researchers found that mRNA-based COVID-19 vaccines could potentially help patients whose tumors don’t respond well to traditional immunotherapy.

Britain chose finance over industry, austerity over investment, and a closed economy over openness to the world.

Polytetrafluoroethylene (PTFE) is a highly versatile material that has found widespread application owing to its exceptionally high chemical resistance and thermal stability. However, these properties mean that PTFE disposal is an energy intensive process, producing fluorinated materials which pose serious concerns regarding toxicity and environmental persistence. Herein we report a straightforward mechanochemical approach for the reductive defluorination of PTFE generating an environmentally benign mixture of elemental carbon and sodium fluoride. The process employs cheap and readily available chunks of sodium metal, proceeding rapidly at room temperature, in the absence of any organic solvent to form sodium fluoride (NaF) in 98% yield. The fluoride generated in the process can be directly upcycled into fine chemicals through in situ mechanochemical fluorination reactions, delivering valuable sulfonyl fluoride and acyl fluoride products in excellent yields.
