The development of bioactive ceramics still poses challenges in finding a good compromise between bioactivity and mechanical robustness. Moreover, a facile, low-cost and energy-saving synthesis technique is still needed. This study concerns the synth

Both vitrified bottom ashes (VBAs) and waste glasses are forms of inorganic waste material that are widely landfilled, despite having some economic potential. Building on previous studies, we prepared glass-ceramic foams by the combination of VBA wit

The possibility of using a deep eutectic mixture of choline chloride and ethylene glycol in a 1:2 molar ratio (ethaline) for the electropolishing of a WCu composite (~ 71 wt.% of W and ~ 12 wt.% of Cu) has been shown for the first time. It was demons
