#China expands #rareearth #exportcontrols, creating risks for PC component supply — Beijing tightens grip on materials for HDDs and more to protect #nationalsecurity
The updated rules, which take effect in December, cover not just elements like #holmium, #thulium, #erbium, and #ytterbium, but also the technical know-how around how they’re turned into #magnets. As dominant supplier of rare earths globally, China exerting more pressure on supply could have knock-on effects.

Researchers Develop New Techniques For Making Qubits Out of Erbium https://thequantuminsider.com/?p=2360788 #Research #argonne_national_laboratory #erbium #erbium_qubits #UChicago #UChicago_Pritzker_Molecular_Engineering #quantumdaily Insider Brief Scientists have found that an atom of erbium can be a very effective qubit. Two research groups, including a quantum startup founded by UChicago Pritzker Molecular Engineering alumnus and one at U.S. Department of Energy’s Argonne National Laboratory

Erbium: atomic number: 68; weight: 167.259; Lanthanide, rare earth; discovery: 1843—Carl Gustaf Mosander #Poetry #Science #History #Erbium (https://sharpgiving.com/thebookofscience/items/e068.html)

Erbium [Er 068] is a lanthanide, a rare-earth element, originally found in the gadolinite mine in Ytterby, Sweden. A large variety of medical applications (i.e. dermatology, dentistry) rely on the erbium ion's 2940 nm emission, which is highly absorbed in water in tissues, making its effect very superficial making it helpful in laser surgery, and for the efficient production of steam which produces enamel ablation by common types of dental laser. #elements #periodictable #chemicals #erbium
