Search for Rare Earths, Key Materials for Energy Innovation

submitted by: RASEIBoulder
Rare earth minerals are difficult and expensive to mine. And like most mining activities, doing so results in environmental damage, particularly because the ores from which these metals are extracted can be radioactive. Chinese mines have produced rare earths at a much lower cost, forcing competitors to shut down in recent years and creating a near monopoly. Japan is developing technology to improve recycling of some rare earths from discarded electronic products. And it is seeking...

Rock damage, Earthquakes and Faults in the Brittle Crust Yehuda Ben-Zion Department of Earth Sciences University of Southern California, Los Angeles We review observational and theoretical results on seismic radiation and brittle rock damage in two complementary problems. (i) Rapid damage generation by sources with sufficiently high amplitude and subsequent gradual healing. (ii) Effects of brittle rock damage within the source volume on the seismic radiation to the bulk. (i) Analysis...

From sensor selection to data return: lessons learned (Panel Session)

submitted by: kkwaiser
Each panel member was asked to open with a 5-7 minute narrative based on personal experience on the topic of advanced aquatic sensors. Team assembly, funding avenues, technology considerations, and any of the minutia involved in deploying and operating advanced aquatic sensors may be discussed. This talk and others were part of the Advanced Aquatic Sensors (AAS) Workshop funded by the National Science Foundation (NSF) and held at the University of Michigan Biological Station from September...
