TL;DR: In this article, the synthesis of Ti3C2Tx (and Ti2CTx alike) MXenes is performed with a new etching environment (FeF3/HCl).

TL;DR: The calculation of the electron spatial distribution in the confinement potential shows that the high-mobility electrons responsible for superconductivity set at the edge of the gas whose extension can be tuned by the field effect.

TL;DR: This work examines the magnetic-field-driven quantum phase transition that occurs in electrostatically gated superconducting LaTiO3/Sr TiO3 interfaces and shows that it belongs to the (2+1)D XY model universality class.

TL;DR: In this article, the authors highlight how etching agents govern surface chemistries of Ti3C2Tx, the most widely studied MXene to date, and demonstrate that the etching agent strongly modifies the nature of surface terminal groups (F, OH and/or O), oxidation sensitivity, delamination ability, nature of inserted species, interstratification, concentration of defects and size of flakes.

TL;DR: It is shown that the Fermi energy lies intrinsically near the top of the quantum well and beyond a filling threshold, electrons added by electrostatic gating escape from the well, hence limiting the possibility to reach a highly-doped regime.
