(Phys.org)—In nanoscience, the ultimate goal is to design better materials and devices by controlling the positions of the atoms, molecules, and molecular clusters on a substrate with exact precision. In a new study, researchers ...
(Phys.org)—It would seem that figuring out how many molecules of water are needed to form the smallest, or most basic ice crystal would have been discovered long ago, but that is not the case, because to measure both the ...
(PhysOrg.com) -- The universe was created 13.73 billion years ago in a blaze of light -- the big bang. We also think that, about 380,000 years later, after matter (mostly hydrogen atoms) had cooled enough for neutral atoms ...
