U.S. Naval Research Lab to Design UUVs with ‘Shark Skin-Like Surfaces’ Our Bureau 1176 U.S. DoD photo. For representation only. The U.S. Naval Research Laboratory (NRL) is developing unmanned underwater vehicles (UUVs) with shark skin-like surfaces that provides better speed and energy efficiency. The idea was provided by Nicole Xu, Ph.D., a NRL Postdoctoral Research Associate from the Laboratories for Computational Physics & Fluid Dynamics. “Shark skin comprises arrays of teeth-like denticle structures, which contribute to fast and stealthy swimming by turbulent drag reduction,”...

By Iacovos Vasalos, Research Director Emeritus, Center for Research and Technology-Hellas Special to The Digest This report summarizes highlights from the ABLC 2020 Biofuels Digest Virtual Conference, which took place in July 7-10, 2020. (And if you haven’t already registered for this year’s ABLC Digital on May 3-7, 2021, check it out now here.) There were almost 100 presentations in various areas of technology. These represent work carried out, mainly in United States, in National Labs, Universities and companies. Because most of the academic work in bioeconomy is mainly funded by the De...
