source:miningCritical Metals Corp (Nasdaq: CRML) says drilling at its Tanbreez project in southern Greenland has led to the discovery of one of the world’s highest concentrations of gallium, further demonstrating the value of what is already a world-class rare earth asset.By total resource count, Tanbreez is currently ranked the largest rare earth deposit in the world at 28.2 million tonnes of total rare earth oxides (TREO), contained within 4.7 billion tonnes of material. This resource is expected to contain over 27% heavy rare earth elements (HREE), which carry higher value than light rare e...

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...
