A single crystal of a silicate of a rare earth element herein provided is characterized in that it has a Ce concentration of not less than 0.6 mole % and not more than 5 mole % and that it has a light transmittance, as determined at a wavelength of 450 nm, of not less than 75%. ...
Metallic crystals are lustrous and are very good conductors of heat as well as electricity. Metallic crystals are quite...
Clear Quartz (according to this book) is linked to the Storm Element, Gold (used to create Aqua Aura) is associated with the Earth Element while Platinum and Silver (used for Angel Aura) is associated with Earth and Storm respectively. Siobhan Gouws-Moller, from SGCrystalHealing DISCLAIMER: W...
Although there are no concrete expressions of Zeff, the effective atomic number for photoelectric absorption can be expressed as Zeff = (ΣwiZi4)1/4 [23], where wi and Zi are the fraction of the total mass associated with the ith element and the atomic number of the ith element, ...
Infinite stone is a powerful earth element stone that renews energy and aligns one's energy with the Earth. Use a small piece of Infinite as a worry stone, put a larger piece next to or under your pillow for more restful sleep, and try using extra large pieces as massage tools. The ...
Now, moreover, so-called the third-generation scintillators with the formula RE2SiO5, where R is a rare earth element, have been found to possess excellent scintillation properties, including Lu2SiO5 (LSO), Gd2SiO5 (GSO), and Y2SiO5 (YSO). The PWO crystal (Figure 14) has a high ...
Zodiac Element:Earth Associated Colour:Grey Compatible Zodiac Signs:Taurus and Virgo Capricorn Personality Traits:Ambitious, logical and hard-working What is the Capricorn Birthstone? Capricorns have a great list of crystals that are favourable to them, and many stones can expel negative energies from...
Petrology and major element geochemistry of Peru margin phosphorites and associated diagenetic minerals: Authigenesis in modern organic-rich sediments New petrographic and major element geochemical data from modern Peru margin upper slope-outer shelf phosphorites are presented, which provide insight into ...
Quartz (SiO2) is one of the most abundant minerals in the earth's crust. It has been widely used in electronics as the key element in oscillator circuits. These oscillators use the mechanical resonance of a piezoelectric material to generate signals with a precise frequency, which requires high...
This study focuses on the use of a rare-earth element, Yb2+, as a potential luminescence center for scintillators. Yb2+ possesses a closed-shell 4f14 configuration that is similar to the ground-state configuration of Eu2+, which has a half-filled 4f7 configuration. Yb2+ also exhibits broa...
