In a breakthrough development, scientists have shown that they can successfully amplify light using electrically excited films of the chemically synthesized semiconductor nanocrystals known as quantum ...

Let's say you have a project indoors. The emissions caused by a gasoline-, diesel-, or propane-powered mixer/pump would force you to figure out a way to get the slurry to where you need it. What if ...

In our July 2005 issue we talked about controlling underhood temperatures and how lower temperatures can result in increased horsepower production. The use of larger, more efficient radiators, cooling ...

Exciton-polaritons are hybrid light–matter quasiparticles with mixed photonic (small effective mass) and excitonic (strong nonlinearities and fast relaxation) properties that enable a rich set of ...
