The estimated lifetime of the most prominent optical emission of samarium
from the [sup.4][G.sub.5/2] level is 0.726 ms.
FTIR analysis for pure and doped ZnO samples admitted the existence of O-H and Zn-O stretching modes around 3451[cm.sup.-1] and 428 [cm.sup.-1], respectively, with a peak shift regarding Zn-O stretching mode attributed to modifications in parameters and bond properties of ZnO lattice when perturbed by samarium
The method of separating neodymium and samarium
oxides from mined raw ore, then reducing those oxides to a usable metallic element is difficult.
Government should provide incentives (tax breaks, contract preferences, and so forth) for domestic companies striving to revive REE mining, refining of neodymium or samarium
, or production of rare earth magnets.
The M1A2 Abrams tank uses samarium
cobalt magnets in its reference and navigation system.
With a 17mm diameter state of the art Samarium
Cobalt magnet, low thermal mass and an aluminium knob for easy handling, these probes will quickly and securely attach to ferrous substrates making them faster to attach and more secure than an exposed junction probe.
In contrast, the decay of samarium
(Sm), to neodymium (Nd), provides one of the best tracers for tectonic processes (e.g.
The Cobalt-Samarium (CoSm) magnet is made of iron, nickel, cobalt and rare-Earth Samarium
* Commonly neodymium iron boron or samarium
Cytogen's marketed products include QUADRAMET(R) (samarium
Sm-153 lexidronam injection), PROSTASCINT(R) (capromab pendetide) kit for the preparation of Indium In-111 capromab pendetide, and SOLTAMOX(TM) (tamoxifen citrate, oral solution 10mg/5mL) in the United States.
The scientists are working with the following lanthanide oxides: lanthanum, cerium, praseodymium, neodymium, samarium
The scientists are working with seven lanthanide oxides: lanthanum, which is used in carbon lighting applications and optical glass manufacturing; cerium, used as a catalyst in sell-cleaning ovens; praseodymium, commonly used in an alloy found in lighter flints and carbon electrodes for are lighting; neodymium, used for coloring glass and ceramics and for filtering infrared radiation; samarium
, used in magnets, in alloys with cobalt, and in nuclear reactors: and gadolinium, which is also used in magnets.
