A crew of UC Riverside researchers has uncovered a possible breakthrough in photo voltaic desalination that would scale back the necessity for energy-intensive saltwater therapy.
Led by Luat Vuong, an affiliate professor of mechanical engineering in UCR’s Marlan and Rosemary Bourns Faculty of Engineering, the crew has demonstrated for the primary time how the best frequencies of daylight—particularly invisible ultraviolet (UV) gentle—can break the cussed bonds between salt and water.
“To our knowledge, nobody else has yet articulated this deep UV channel for salt-water separation,” Vuong stated. “UV light in the wavelength range of 300–400 nanometers is used for disinfection, but this deep UV channel, around 200 nanometers, is not well known. We may be the first to really think about how you can leverage it for desalination.”
Whereas a lot work stays earlier than sensible functions are developed, the invention offers a transparent path for additional analysis and innovation.
Printed in ACS Utilized Supplies & Interfaces, the examine by Vuong and her colleagues particulars how the crew made a wick from aluminum nitride—a tough, white ceramic—to separate salt from water by harnessing particular gentle wavelengths…
