source:CNBCJakarta, CNBC Indonesia - RI punya banyak anugerah sumber daya alam seperti pertambangan. Beberapa sumber daya alam sektor pertambangan yang dimiliki Indonesia yakni nikel, emas, tembaga, batu bara, maupun timah.Namun selain itu, RI juga dianugerahi sumber alam pertambangan yang belum dikembangkan yakni logam tanah jarang (LTJ) atau Rare Earth Element. 'Harta karun'ini dinamai logam tanah jarang karena didasarkan pada asumsi yang menyatakan bahwa keberadaan logam tanah jarang ini tidak banyak dijumpai.LTJ ini melimpah dibandingkan dengan unsur lain dalam kerak bumi. Sumber d...

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...
