source:phys.orgBlue lasers, lasers that emit a light beam with a wavelength between 400 nm and 500 nm, are key components of various technologies, ranging from high-resolution displays to printers, medical imaging tools and data storage solutions. A key advantage of these lasers is that they generate coherent and intense light beams that can be leveraged to develop highly advanced optical technologies.One approach to developing blue lasers entails the use of colloidal quantum dots (CQDs). These are nanoscale semiconducting particles with unique optical properties associated with their size.Las...

source: Tohoku UniversityCatalysts are the keys to speeding up sluggish reactions that require large amounts of energy. Therefore, analyzing which types of catalysts speed up reactions the most and what their underlying mechanisms are can help us improve efficiency.A research team at Tohoku University's Advanced Institute for Materials Research (AIMR) has proposed a strategy to use spinel oxides to improve a reaction called the oxygen evolution reaction (OER). This catalyst overcomes issues typically encountered with previous spinel oxides by involving a rare-earth cerium (Ce) substitution...
