Wave energy converters

, 2011
Long before scientists ever put forward a reasoned description of the phenomenon based on fluid mechanics equations, men were aware of the power of ocean waves through observing natural phenomena. This awareness came from navigating at sea and coming into contact with the infamous “freak waves”, or from experiencing the damage caused onshore by storm ...

Powering Nanocrystal‐Based Heat Engines With Light‐Emitting Metasurfaces That Influence Their Temperature

Advanced Functional Materials, EarlyView.
Metasurfaces and other structured photonic environments can dramatically modify the absorption and/or light emission of semiconductors. However, the consequences of these changes on the temperature of the system are not well understood. The authors address this problem for colloidal nanocrystals and leverage their findings to convert light into ...
