Laser Cladding Treatment for Refurbishing Disc Brake Rotors: Environmental and Tribological Analysis
Tribology letter, 2021 In this study, grey cast iron disc brake rotors are refurbished by adding a surface layer through laser cladding. Current methods to deal with replaced rotors mainly include remelting, with a minority fraction disposed in landfill. Both approaches result

Precisely spun super rotors [PDF]
Nature Communications, 2021 AbstractImproved optical control of molecular quantum states promises new applications including chemistry in the quantum regime, precision tests of fundamental physics, and quantum information processing. While much work has sought to prepare ground state molecules, excited states are also of interest. Here, we demonstrate a broadband optical approach

On the scaling of wind turbine rotors
Wind Energy Science, 2020 . This paper formulates laws for scaling wind turbine rotors. Although the analysis is general, the article primarily focuses on the subscaling problem, i.e., on the design of a smaller-sized model that mimics a full-scale machine.
