(Phys.org)—Aromatic molecules are a staple of organic chemistry. Aromatics, like benzene, have a unique pi-electron character that makes the ring structure exceptionally stable. While aromatics are typically reserved for ...
In 1999, UCLA professor John Miao pioneered a technique called coherent diffractive imaging, or CDI, which allows scientists to re-create the 3D structure of noncrystalline samples or nanocrystals. The achievement was extremely ...

(Phys.org)—In 2011, scientists from the Institute Langevin in Paris built an array of 49 empty coke cans that resonate when exposed to an acoustic wave, causing the cans to produce sound similar to the way blowing across ...
Transportation accidents, such as trucks crashing on a highway or rockets failing on a launch pad, can create catastrophic fires. It's important to understand how burning droplets of fuel are generated and behave in those ...
