Naturally occurring uranium consists of three isotopes: uranium-234, uranium-235 and uranium-238.Although all three isotopes are radioactive, only uranium-235 is a fissionable material that can be used for nuclear power.Atomic Number: 92 Atomic Weight: 238.02891 Melting Point: 1408 K (1135°C or 2075°F) Boiling Point: 4404 K (4131°C or 7468°F) Density: 18.95 grams per cubic centimeter Phase at Room Temperature: Solid Element Classification: Metal Period Number: 7 Group Number: none Group Name: Actinide Radioactive What's in a name? Radioactivity was first discovered in 1896 when Antoine Henri Becquerel, a French physicist, detected it from a sample of uranium.

Once xenotime has been depleted, monazite and garnet are generally on opposite sides of reactions because they represent the two dominant sinks for Y in pelitic rocks. (2005) Analytical perils (and progress) in electron microprobe trace element analysis applied to geochronology: Background acquisition, interferences, and beam irradiation effects.

Monazite growth reactions correspond to garnet breakdown and vice versa (see Pyle and Spear, 1999; Gibson et al., 2004).

History and Uses: Uranium was discovered by Martin Heinrich Klaproth, a German chemist, in the mineral pitchblende (primarily a mix of uranium oxides) in 1789.

Today, uranium is obtained from uranium ores such as pitchblende, uraninite (UO), is most commonly used in the nuclear power industry to generate electricity.

The AVLSI Lab has its own state-of-the-art test equipment procured with institute support.

More than 100 chips have been designed in this lab, fabricated and successfully tested.

Although monazite may originate via allanite breakdown in some pelitic rocks, many metamorphic rocks have a number of monazite generations and thus a number of monazite-in reactions (see Spear and Pyle, 2002; Wing et al., 2003).

The partitioning of Y and HREE between garnet, monazite, and xenotime may be the most commonly used and successful link between monazite and chemical reactions.

Currently more than 60 Ph D students and full time MS students work under the ambit of the lab.
