Investigation of rare earth elements in urine and drinking
Rare earth elements (REEs) have a total of 17 elements, including 15 lanthanide elements in the periodic table group IIIB, with atomic numbers ranging from 57 to 71. These are lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), samarium (Sm), promethium (Pm), europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Yb
Investigation of rare earth particulate on tribological
01/07/2019· Rare earths (REs) elements have been increasingly used as reinforcement material in various aluminium matrix composites due to their high strength at room temperature, good thermal conductivity and mechanical properties. Luminescence properties as well as mechanical properties of composites reinforced with silica have been improved with different wt% of the europium as a rare earth
Rare Metal and Rare Earth Investigation : Atomic
Rare Metal and Rare Earth Investigation. Rare Metals (RM) include Niobium (Nb), Tantalum (Ta), Lithium (Li), Beryllium (Be), Cesium (Cs) etc. and Rare Earths (RE) include Lanthanum (La) to Lutetium (Lu) besides Scandium (Sc) and Yttrium (Y). These metals are strategic in nature with wide application in the nuclear and other high tech industries such as electronics, telecommunication
Race is on for Indonesia's untapped rare earths Asia
09/09/2020· JAKARTA Rare earth, the experts like to say, is neither rare nor is it earth. But given its use in everything from smartphones to high-tech aerospace and defense systems, a potential buried treasure from the past may soon become the next big thing in Indonesian mining.
A rare earth element and Nd isotopic investigation into
15/06/2020· The rare earth element and yttrium (REY), especially light–to–middle–to–heavy rare earth element (REE) ratios, Y/Ho ratios, Eu and Ce anomalies, coupled with Nd isotope systematics, are particularly useful for such studies due to their coherent behavior in geochemical systems, and can be used as a proxy not only for constraining the relative magnitude of continental and hydrothermal
An investigation of rare earth chloride mixtures
An investigation of rare earth chloride mixtures: combinatorial optimisation for AA2024‐t3 corrosion inhibition Rare earth (lanthanides) cations have demonstrated exceptional activity as cathodic corrosion inhibitors for aluminium alloys (AAs). While Ce is generally regarded as the most active, there have been reports of synergistic interactions between mixtures of rare earths, which

Investigation of rare earth elements in urine and
June to July 2015. The contents of rare earth elements were determined using inductively coupled plasma mass spectrometry. The detection rates of rare earth elements, including yttrium (Y), lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), and samarium (Sm), in the urine of children in the exposed group were all 100%, except for samarium (98%); the rates in the control group were

Ionprobe Investigation of Rare Earth Element
The rare earth element (REE) characteristics of feldspars and garnet in two metasedimentary xenoliths from Kilbourne Hole, New Mexico, have been determined by secondary ion mass spectrometry. Mass balance considerations show that the majority of the REE reside in the major mineral phases of these xenoliths, in contrast to silicic granitoids and rhyolites where most of the REE reside in
