source:The Business TimesCOMMODITY prices have climbed significantly since the start of the year, amplified by supply concerns arising from the Russian invasion of Ukraine. Within the commodity complex, we turn our attention to rare-earth metals (REMs), a specific group of metals with chemical properties that are considered “rare” due to large extraction costs. REMs are vital for advanced technologies, and their unique chemical properties mean that they cannot be easily substituted by traditional metals. We believe investors should not overlook REMs when investing in commodities.Supply-demand ...

source:ScitechDailyComplex networks of systems are required for sharing real-time information. Switching the magnetization, or electron spin, of magnetic materials with ultra-short femtosecond laser pulses is a promising strategy for speeding up data storage devices. However, how the spin evolves in the nanoworld on extremely short time scales, such as one-millionth of one billionth of a second, has remained largely mysterious. In collaboration with TU Wien, Austria, the French national synchrotron facility (SOLEIL), and other international partners, Professor François Légaré’s ...
