(Phys.org)—It was another banner week for physics as one team at Cornell verified the 'Zeno effect,' whereby atoms won't move while observed. They conducted experiments in an Ultracold Lab and found that atoms that normally ...
A luminescent solar concentrator is an emerging sunlight harvesting technology that has the potential to disrupt the way we think about energy; It could turn any window into a daytime power source.
