As the global cumulative installation of solar photovoltaic (PV) devices grows every year, a proportionate number waste PV modules arises because their limited lifespan. It is estimated that by 2050, there will be approximately 60–78 million tonnes (Farrell, C.; Osman, A. I.; Zhang, X. et al. Sci Rep. 2019, 9, 5267). These are bound in strong encapsulated laminate prone to imminent degradation....

For the production of high-performance polyethylene fibers and tapes by ultra drawing, using solid-state processing disentangled nascent ultra-high molecular weight (UHMWPE), maximum draw ratio is an important design parameter, as it determines degree chain alignment and, therewith, properties final product. It would, therefore, be advantageous to have a fast scanning method estimate drawabilit...

Low pressure dehydroxylation of serpentine phases is important in processes such as the inertialisation of chrysotile asbestos or the CO2 sequestration in ultramafic rocks. Although research on the mechanism of this process goes back to the forties of last century, the dehydroxylation mechanism is still not fully elucidated. In this study with used non-isothermal thermogravimetric (TGA) analyse...
