New work with the material rhenium disulfide reveals a surprising degree of control over how heat flows through layered structures. By carefully stacking atomic sheets, scientists can dramatically alter…...

16+ hour, 8+ min ago  (296+ words) These elements accumulate particularly around misfit dislocations, defects in the crystal structure, creating localized traps that dramatically alter the interface's behaviour. Antimony, tin, phosphorus, and arsenic substantially weaken the cohesion of coherent interfaces, whereas nickel has minimal effect and chromium…...
