TL;DR: A highly active and durable class of electrocatalysts is synthesized by exploiting the structural evolution of platinum-nickel (Pt-Ni) bimetallic nanocrystals by exploitingThe starting material, crystalline PtNi3 polyhedra, transforms in solution by interior erosion into Pt3Ni nanoframes with surfaces that offer three-dimensional molecular accessibility.

TL;DR: The results firmly show that high power factors can be realized by adjusting the total filling fraction of fillers with different charge states to reach the optimum carrier density, and lattice thermal conductivity can also be significantly reduced, to values near the glass limit of these materials.

TL;DR: Li et al. as mentioned in this paper studied three representative solid electrolytes with neutron depth profiling and identified high electronic conductivity as the root cause for the dendrite issue, which is the most common cause of lithium dendrites.

TL;DR: The Stardust spacecraft collected thousands of particles from comet 81P/Wild 2 and returned them to Earth for laboratory study, and preliminary examination shows that the nonvolatile portion of the comet is an unequilibrated assortment of materials that have both presolar and solar system origin.

TL;DR: Nanocages of platinum are fabricated by depositing a few atomic layers of platinum as conformal shells on palladium nanocrystals with well-defined facets and then etching away the Pd templates.
