Advances in permanent magnets, electronics and design techniques over the past thirty years have led to the development of a new generation of electric machines. Sintered rare-earth neodymium–iron–boron magnets have a magnetic energy product up to an order of magnitude larger than those of...

We explored the application of Low-Intensity Pulsed Ultrasound (LIPUS) technology to improve the metabolic activity of microorganisms. In this study we showed that LIPUS improves bio-ethanol production from lignocellulosic biomass. We determined specific LIPUS conditions to increase the...
