" Her originality and her courage to take up new challenges already made her stand out in the MSc program. "
" Ms. Souren is blessed with exceptional willpower and perseverance as well as with golden penmanship. "
" Holy cow! ...you did such a great job... "
" Fantastic, all these names! Thanks so much. It’s making me feel sunny and inspired. "
" I’d love to claim the article for my own, but I didn’t provide much input. You can remove my name on the article. "
" Ms. Souren's expertise on the subject was very helpful. "
" Good that you spotted that error. The writer as well as the undersigned, the client, and the editor had missed it! "
" I liked what you had done. I had a few of the references, but most were ones I hadn’t seen. As I suspected, no one has done the math properly yet. "
" Ms. Souren is unconventional in many regards. Not one of the least important aspects of that is her versatility. "
" I hardly know any earth scientists with broader scientific interests and matching experience. "
" She thoroughly familiarized herself with knowledge at the interface of the earth sciences, microbiology and chemistry. "
" Thank you very much for your edits. I loved it! "
" ... a job well done - I like it very much... "
" I really like this class, particularly because the labs really address the issues covered in the lectures. "
" Very soon, Ms. Souren was able to execute and complete these extremely difficult and labor-intensive analyses all by herself, both in the chemistry laboratory as well as with the mass spectrometry. "
" I wanted to let you know that we've enthusiastically followed up on your tip... Thank you for your attentiveness. "
" You produced a very thorough search with quite a few references that look promising. This search was superior to another outside search that was attempted last month. "
Rare earth elements are becomimg a hot issue now that major producer China is limiting their export more and more. A little under a year ago, the newspaper item described below drew my attention. Since then, the situation has even tightened up more.
September 2009: Rare Earth Elements in the news, and on the stock market
A recent issue of The Observer included an article in association with The New York Times in the Money & Business section that drew my attention. The headline read "China Tightens Grip on Rare Minerals".
It turned out to be an article on Rare Earth Element (REE) production by China. These elements take up a special position in the Periodic Table - as do the actinides - and alternatively are called lanthanides (although it depends on how you define them).
China supplies over 99% of the world's Dy and Tb, says the article, and 95% of the world's Nd. One mine in Baotou in Inner Mongolia produces half the world's REEs.
Apparently, two mining companies - Lynas Corporation and Arafura Resources - were about to open two Australian mines and change all that, but are likely to end up at least partly in Chinese hands because they lost their financing.
Avalon Rare Metals is now trying to open a mine in Canada and Molycorp Minerals wants to reopen one in California, according to the article, and it sounds like their shares recently did pretty well.
Intriguing aspect is that some of the REEs used in green technologies, including lightweight magnets in wind turbines, originate from high-pollution, low-cost mining in China. Did you know that the electric motor of a Toyota Prius contains 1 to 2 kilograms of Nd?
If you want more details, also about the mining technology involved, please see the original article on China's increasing control of rare earth element production, which was written by Keith Bradsher and published on page B1 in the NY edition of the New York Times on September 1.
That version is better than what was on page 5 of the NYT section in The Observer (which looks like it was edited by someone who does not know what REEs are).
