Coal and coal combustion byproducts can have significant concentrations of lanthanides (rare earth elements). Rare earths are vital in the production of modern electronics and optics, among other uses. Enrichment in coals may have been a function of a number of processes, with contributions from volcanic ash falls being among the most significant mechanisms. In this paper, we discuss some of Mineralogy and geochemistry of No.6 Coal from the Heidaigou Mine of the Jungar Coalfield of North China were studied using instrumental neutron activation analysis, inductively coupled-plasma mass spectroscopy, X-ray fluorescence spectrometry, and

A discovery of a solid rock mega-planet is a great event for astronomers as the absolute majority, or 75 percent, of the planets discovered by Kepler space observatory are gas giants with diameters less than four times of that of Earth's.

NASA's Kepler Discovers First Earth

2018/9/23Astronomers have discovered the first Earth-size planet orbiting a star in the habitable zone -- the range of distance from a star where liquid water might pool on the surface of an orbiting planet. The discovery of Kepler-186f confirms that planets the size of Earth

The LHC was first fired up in September 2008 and in 2012 the machine was responsible for the discovery of the Higgs Boson, the God Particle. Higgs Boson is a particle that is said to be the particle that makes all matter and led to the creation of our universe. CERN want to use the LHC to find out the fundamentals of our universe and how it was created, they want to recreate the Big Bang and

Note: It should be noted here that while Super Glue was originally invented by accident thanks to WWII, it was not, as a popular urban legend tells, accidentally discovered by soldiers in WWII who then subsequently began using it to seal up battle wounds. Rather

2020/8/25A gallium scan uses gallium citrate. It's a drug that has very small amounts of radioactive gallium. A day or two before your scan, your healthcare provider injects the gallium citrate into a vein in your arm. The gallium then travels all over your body. It builds up in

Docudrama Movie 'Supervolcano' by BBC and Discovery

In the Spring of 2006, a BBC Science and Discovery Channel docudrama called "Supervolcano" was followed by the documentary, "Supervolcano: The Truth About Yellowstone." For all of its doomsday atmosphere, "SuperVolcano" may just be the best thing that's happened to Yellowstone –

(With this assumption gA/gV gets into the picture through the Goldberger-Treiman relation, [14] which gives gA/gV in terms of the pion decay constant and the pion nucleon coupling.) Here, in this relation between the currents of the symmetries of the strong interactions and the physical currents of beta decay, there was a tantalizing hint of a deep connection between the weak interactions and
