Enhancing solar cells with nanoparticles
Deriving plentiful electricity from sunlight at a modest cost is a challenge with immense implications for energy, technology, and climate policy. A paper in a special energy issue of Optics Express, the Optical Society's (OSA) open-access journal, describes a relatively new approach to solar cells: lacing them with nanoscopic metal particles. As the authors describe in the article, this approach has the potential to greatly improve the ability of solar cells to harvest light efficiently.

Cavitation in Ultrasonic Cleaning and Cell Disruption
It is important to quantify the cavitation energy in all applications ranging from ultrasonic cleaners to cell disruptors. A cavitation meter measures the energy intensity and frequency within ultrasonic and megasonic cleaners, including probes with side-mounted sensors that can be placed within the megasonic jet streams and single wafer cleaners, as well as those resembling a beaker to quantify the energy emanating from the ultrasonic horns used for cell disruption and homogenizing.
