Recently YH6, compound from a group of theoretically predicted stable compressed MH6 hydrides (M/ Ca, Mg, Y, Sc) with bcc Im-3m crystal structure, was successfully experimentally realized. Superconductivity pressurized YH6 confirmed experimentally, Tc / 224 K at 166 GPa, but critical temperature considerably lower than value by Migdal-Eliashberg (ME) theory. Here we present theoretical reinvest...

Abstract Maples ( Acer sp.) are trees/shrubs of extraordinary aesthetic value, what favours them for wide utilisation in urban greenery. However, some the non-native species became invasive new range and represent a threat to natural ecosystems.
