Web archive with astronomical photographic plates goes online

Lots of little dots with no apparent pattern: Where laypeople may just see milky gray photos sprinkled with what look like random crumbs, it is enough to make astronomers' hearts miss a beat. We are talking about historical ...

New device gets scientists closer to quantum materials breakthrough

Researchers from the University of Nebraska-Lincoln and the University of California, Berkeley, have developed a new photonic device that could get scientists closer to the "holy grail" of finding the global minimum of mathematical ...

Intrinsic optical nonlinearities and carrier dynamics of InSe

Recently, researchers in Shanghai Institute of Optics and Fine Mechanics (SIOM) of the Chinese Academy of Sciences carried out a systematic investigation on the microscopic optical nonlinearities and transient carrier dynamics ...

New method helps exfoliate hexagonal boron nitride nanosheets

Chinese researchers recently reported an innovative mechanical process for controllably exfoliating hexagonal boron nitride nanosheets (h-BNNSs).This method, known as the "water-icing triggered exfoliation process," was proposed ...

New, highly tunable composite materials—with a twist

Watch for the patterns created as the circles move across each other. Those patterns, created by two sets of lines offset from each other, are called moiré (pronounced mwar-AY) effects. As optical illusions, moiré patterns ...
