(PhysOrg.com) -- "One of the many reasons people study ultracold gases is for their potential as model quantum systems," Deborah Jin tells PhysOrg.com. "There is a need to model quantum many-body systems because a lot of ...
Rice University chemists have produced a catalyst based on laser-induced graphene that splits water into hydrogen on one side and oxygen on the other side. They said the inexpensive material may be a practical component in ...

(Phys.org)—A team of German and Italian chemists working at the University of Rostock has discovered a way to extract hydrogen from methanol at low temperatures and ambient pressure using a common catalyst. As they report ...
JILA researchers have made a long-lived, record-cold gas of molecules that follow the wave patterns of quantum mechanics instead of the strictly particle nature of ordinary classical physics. The creation of this gas boosts ...
