A review is presented on laboratory modeling of diffusion downwind of a continuous point source within a boundary layer of well defined height with turbulence driven by buoyant convection. Results of ...

A cotton swab is dipped into concentrated hydrochloric acid (producing hydrogen chloride gas) while a second on is dipped into concentrated aqueous ammonia (producing ammonia gas). Both cotton swabs ...

In contrast to the conventional view that surface-trapped holes in CdS and CdSe nanoparticles are static and immobile, recent experimental and theoretical work has shown that these holes are dynamic ...
