TL;DR: A scalable method is shown for the fabrication of strong and highly conducting pure MXene films containing highly aligned large MXene flakes that provide an effective route for producing large-area, high-strength, and high-electrical-conductivity MXene-based films for future electronic applications.

TL;DR: In this paper, multiwalled carbon nanotubes (MWCNTs) were oxidized in air and acids while varying the treatment time and/or temperature, and it was found that while an oxidation for 6 h in H2SO4/HNO3 provided the strongest effect, a flash oxidation in air (15 min at 550 °C) also leads to an efficient functionalization in a cost-effective and environmentally friendly way.

TL;DR: This work opened a pathway for investigating the mechanical properties of monolayers and bilayers of other MXenes and extends the already broad range of MXenes’ applications to structural composites, protective coatings, nanoresonators, and membranes that require materials with exceptional mechanical properties.

TL;DR: Heterocyclic pyrrole molecules are in situ aligned and polymerized in the -absence of an oxidant between layers of the 2D Ti3C2Tx (MXene), resulting in high volumetric and gravimetric capacitances with capacitance retention of 92% after 25,000 cycles at a 100 mV s(-1) scan rate.

TL;DR: The use of selective extraction of one or more elements from the precursor materials releases 2D structures that in turn will result in expanding the world of nanomaterials in general and 2D materials in particular, generating new materials that cannot be produced by other means.
