source:Laboratory EquipmentA new luminescent sensor can detect terbium, a valuable rare earth element, from complex environmental samples like acid mine waste. The sensor, developed by researchers at Penn State, takes advantage of a protein that very specifically binds to rare earth elements and could be harnessed to help develop a domestic supply of these metals, which are used in technologies such as smart phones, electric car batteries, and energy efficient lighting. A paper describing the sensor appears in the Journal of the American Chemical Society.Terbium, one of the rarest of the rare ...

source:TechexploristTerbium is one of the rarer rare-earth elements. It produces the green color in cell phone displays and is also used in high-efficiency lighting and solid-state devices. However, there are various chemical, environmental, and political challenges to obtaining terbium and other rare earth elements from the environment.Scientists at Penn State have developed a new luminescent sensor to detect terbium from complex environmental samples like acid mine waste. The sensor relies on a protein called lanmodulin. The protein binds to rare earth elements than to other metals. Its sele...

source:OILPRICEThe European Union is considering proposals and ideas to support manufacturers of rare earth magnets—key elements in electric vehicles—as the EU looks to reduce supply chain dependence on China and reach net-zero emissions by 2050, sources familiar with the plan told Reuters.Permanent rare earth magnets are critical to the energy transition because they are used in electric vehicles (EVs) and wind turbines. They contain rare earth minerals, a sector in which China currently dominates the global market and supply chains. Europe, as well as the United States, has made steps to ens...

This need has gained greater urgency because of the global coronavirus (COVID-19) pandemic, as effective sterilization practices can curtail the spread of infectious diseases.Current sources like mercury lamps are bulky, contain toxic chemicals, and are not as versatile in applications as semiconductor light sources. Aluminum gallium nitride (AlGaN) is the mater...
