Abstract: Abstract Molecular dynamics simulations are performed to investigate temperature- and stress-induced phase transformations in nanocrystalline nickel-titanium shape-memory alloys. Our results provide detailed insights into the origins of the experimentally reported characteristics of phase transformations at… read more here.

DOI: 10.1126/sciadv.1700419
Abstract: Latitudinal biodiversity gradients differ between reef fishes and mobile macroinvertebrates at local but not regional scales. Among the most enduring ecological challenges is an integrated theory explaining the latitudinal biodiversity gradient, including discrepancies observed at… read more here.
