(Phys.org)—Conventional membranes used for sieving atomic and molecular species cannot scale to the subatomic level, making them unable to separate hydrogen isotope ions (protons, deuterons and tritons). At the same time, ...
Two complementary methods work together in a study forthcoming in The Auk: Ornithological Advances, producing more refined estimates of where individual Barn Swallows spend the winter. Using the methods separately comes with ...
