TL;DR: The structure of this, only second MXene with formula M4X3, was investigated with pair distribution function analysis, and the resistivity of a cold-pressed disc was 0.0046 Ω m, rendering this MXene one of the most conductive to date.

TL;DR: The performance of electrodeposited manganese oxide films (MnOx) is improved when they are "activated" by potential cycling protocols, as measured by Tafel analysis (where lower slope is better): upon activation the Tafels slope decreases from ∼120 to ∼70 mV/decade in neutral conditions and from ∼650 to ∼90 mV /decade on acidic solutions.

TL;DR: The electronic properties of these Mo-containing MXenes are compared with their Ti3C2 counterparts, and are found to be no longer metallic-like conductors; instead the resistance increases mildly with decreasing temperatures, and density functional theory calculations suggest that OH terminated Mo-Ti MXene are semiconductors with narrow band gaps.

TL;DR: The structures of nanocrystalline pristine, potassium hydroxide and sodium acetate intercalated new two-dimensional materials Ti3C2 MXenes were studied using the x-ray atomic pair distribution function technique.

TL;DR: In this paper, the S−Fe distance of sulfate inner-sphere adsorption complexes on iron (Fe) oxyhydroxide (ferrihydrite) surfaces under air-dried conditions using sulfur K-edge extended X-ray absorption fine structure spectroscopy and differential Xray pair distribution function analysis was determined.
