source: News medicalGlioma is an intracranial malignant tumor that still poses a major clinical challenge due to its highly invasive nature, low cure rate, and high mortality rate. Although advanced molecular imaging techniques, such as magnetic resonance imaging (MRI) and computed tomography (CT) can be used for glioma diagnosis, their low spatial resolution, harmful ionization, and complicated workflow limit their application in real-time intraoperative imaging.In a new paper published in Light Science & Application, a team of scientists, led by Professor Hongjie Zhang and Professor Ying...

source:Sourcing & Trading Intelligence for Global Metals MarketsThere’s something afoot on the rare earths front in China. Specifically, the country recently decided that it wants to tighten its export control laws. The regulation passed about two years ago to stop importing countries from diverting “Chinese products for non-intended use.” In most cases, the “products” refer to rare earth elements, of which China is the world’s biggest producer.The announcement comes just a few days after news that an American company may have found the largest reserves of rare earth elements in the US. In...

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 ...
