Various reasons were given for the change, but most observers didn’t expect much of a difference in the overall ratings.

Optical characterization of the synthesized AA-stacked hBN revealed enhanced second-harmonic generation (SHG)—a hallmark of non-centrosymmetric crystal structures—indicating promising ...

With ropes guiding the way, we descend into crystal-filled chambers, discovering stunning formations, shimmering crystal clusters, and even rare, perfectly round crystal "puff balls." This is one ...

Crystal radios can feel magical, given their ability to tune in audio from distant stations with nothing but the energy from the radio signal itself. However, to achieve this feat, they typically ...
