Nanostructuring inorganic solids has been effective as a tool to control the identity of thermodynamically stable phase under ambient conditions for many systems. In addition, size effects can alter not only temperature but also other characteristics transformation—such order, mechanism, and kinetics—which may further be responsible transient existence intermediates, both thermodynamic metastable, accessed in bulk. Since understanding mechanism transformation requires local, even atomistic,...
In situ environmental transmission electron microscopy (ETEM) is an emerging technique among in methods as it allows unique insights into the dynamic processes underlying gas–solid interactions. Aberration-corrected ETEMs providing atomically precise data mimicking benchtop conditions represent state-of-the-art and operando experimentation. New developments ETEM have sparked renewed interest understanding solid–gas interactions, especially regarding catalyst systems, due to their...
The hollow core, concentric graphitic shells, and large surface area of the carbon nano-onion (CNO) make these nanostructures promising materials for highly efficient catalytic reactions. Doping CNOs with heteroatoms is an effective method changing their physical chemical properties. In cases, configurations locations incorporated dopant atoms must be a key factor dictating activity, yet determining structural arrangement on single-atom length scale challenging. Here we present direct...
Lanthanum telluride (La3–xTe4) is a high-performance, next-generation thermoelectric material with dimensionless figure of merit (zT) 1.1 at 1273 K (x = 0.23) and has potential applications in radioisotope generators (RTGs) to power the space missions conducted by National Aeronautics Space Administration (NASA). It been shown that zT can be increased 30% when nickel (Ni) nanoparticle inclusions are introduced La3–xTe4 matrix. The coherent interfaces between Ni likely key factor determining...
