TL;DR: In this article, the authors demonstrate how to etch a laminated (Nb2/3Sc1/3)2AlC MAX phase (solid solution) of both the Sc and Al atoms results in a 2D Nb1.33C material (MXene) with a large number of vacancies and vacancy clusters.

TL;DR: In this paper, the authors review results on the growth of metastable Ti1−xAlxN alloy films by hybrid high-power pulsed and dc magnetron co-sputtering (HIPIMS/DCMS) using the time domain to apply substrate bias either in synchronous with the entire HIPIMS pulse or just the metal-rich portion of the pulse in mixed Ar/N2 discharges.

TL;DR: In this paper, Lu et al. proposed a method to use an advanced photon source at Argonne National Laboratory (ANL) to improve the performance of nanoscale materials.

TL;DR: In this article, a sea urchin-like NiCoO2@C composite electrode architecture is proposed for Li-ion battery and supercapacitor applications based on hollow concave carbon disks, which not only preserves all the advantages of hollow structures but also increases the packing density of active materials.

TL;DR: Solid nanocomposite electrolytes exhibit superior performance to the conventional organic electrolytes with regard to safety and cycle-life and will provide new avenues for the rational engineering of advanced Li-ion batteries and other electrochemical devices.
