Crystal defects critically influence surface chemical reactions in nanomaterials, yet the basic mechanisms at play are still elusive. Here, the authors show the atomic-scale dynamics of surface oxidation at coherent planar defects in Ag and Pd, revea

Micrometre-sized silicon materials can be potentially used in high-capacity lithium ion batteries, owing to their high volumetric energy density, ease of mass production, and low costs, as compared to those of silicon nanoparticles. However, they exh

Optimal design of microelectromechanical devices requires tuning both the size and length scales of their nanocomponents, however the length effect on mechanical behavior of small crystals remains poorly understood. Here, in situ nanomechanical testi

Free-standing nitrogen-doped cup-stacked carbon nanotube (NCSCNT) mats were synthesized and tested as anodes for potassium-ion batteries (KIBs). The edge-open structure character of the NCSCNTs allows a facile insertion of K+ ions into the carbon nan
