: yttrium aluminium garnet 2 micromcontinuouswave laser for the treatment of benign prostatic hyperplasia:a systematic ex-vivo evaluation [J].
The initial steps in designing of thulium
doped fiber amplifier have been started with finding the value of the appropriate pumping power and fiber length of TDF for TDFA.
The economic benefits of mining for rare earth minerals are dependent on the concentrations of the various rare earth elements: light rare earth minerals (neodymium, lanthanum, cerium, praesodymium), heavy rare earth minerals (yttrium, dysprosium, terbium, holmium, erbium, thulium
, ytterbium, lutetium), and medium rare earth minerals (europium, samarium, and gadolinium), since this has an impact on the cost of refining the rare earth minerals and the degree to which there is demand for these various types of elements.
As soon as I have one, say for holmium, then the same probe will work for terbium or thulium
(1) There was already ample Western concern about potential diminishing access to supplies of REEs, particularly after a 2009 draft report written by China's Ministry of Industry and Information Technology called for a total ban on foreign shipments of terbium, dysprosium, ytterbium, thulium
, and lutetium, and a restriction of neodymium, europium, cerium, and lanthanum exports.
In 2009, a proposed six-year economic plan would have banned exports of terbium, dysprosium, yttrium, thulium
, and lutetium.
An internal thulium
single-element standard spike was added (to correct for variable matrix effects during the inductively coupled plasma mass spectrometry analyses) and then the solution was diluted to 1.8 mL with triple-distilled water.
An experiment was carried out using high Thulium
concentration doping technique to shift the thulium-doped fiber amplifier TDFA gain band to the middle wavelength region of the S-band and using dual-wavelength pumping technique .
Name: For Per Theodor Cleve (1840-1905) a professor of chemistry at Uppsala University and the discoverer of the elements holmium and thulium
. "Cleveite" a REE-bearing variety of uraninite was named for him by Nordenskiold in 1878.
The other rare earth elements, including lutetium, yttrium, lanthanum, cesium, praeseodymium, neodymium, gadolinium, holmium, erbium, thulium
, ytterbium, and scandium, would also be potentially applied to ICP-MS-linked immunoassays because they could satisfy the first and second criteria mentioned above.
