The chemical reaction Brand stumbled on was as follows. Urine contains phosphates PO 4 3−, as sodium phosphate (i.e. with Na +) in the form of microcosmic salt, and various carbon-based organics. Under strong heat the oxygen atoms from the phosphate react with carbon to produce carbon monoxide CO, leaving elemental phosphorus P, which comes ...
Wavellite from the Avant Mine, Garland County, Arkansas, showing spherical structure (size: 3.4 x 2.0 x 1.1 cm) Wavellite was first described in 1805 for an occurrence at High Down, Filleigh, Devon, England and named by William Babington in 1805 in honor of Dr. William Wavell (1750–1829), [4] a Devon-based physician, botanist, historian, and naturalist, who brought the mineral to the ...
Francis later discovered more of the brownish orange crystals in sufficient quantity to obtain an X-ray diffraction pattern. This proved that the crystals and the overgrowths were the same, new mineral species. [6] Gathehouseite was named for Bryan Michael Kenneth Cummings Gatehouse for his contributions to the study of oxides and oxysalts.
Around 1604, Vincenzo Casciarolo discovered a "lapis solaris" near Bologna, Italy. Once heated in an oxygen-rich furnace , it thereafter absorbed sunlight and glowed in the dark. In 1677, Hennig Brand isolated a new element that glowed due to a chemiluminescent reaction when exposed to air, and named it " phosphorus ".
Crystals in shades of pink, green, greyish blue, purple and purplish black, as well as colorless. The unique deep purple color of some Blackbird mine specimens is characteristic of the locality. Some single crystals have both purple and green zones. Vivianite crystals from the Blackbird Mine are usually elongated and blade-like.
Erected late last week, the pool is adorned with unpainted plywood and sits behind a tall fence covered by transparent plastic, over which tourists throw coins in the hope of hitting the water.
She shared her discovery on Tik Tok, and is in the process of renovating it into a Zen atrium complete with koi pond.
From an examination of chondrites from this era, 60 new minerals can be identified with crystal structures from all of the crystal systems. [5] These included the first iron-nickel alloys, sulfides, phosphides, and several silicates and oxides. [12] Among the most important were magnesium-rich olivine, magnesium-rich pyroxene, and plagioclase ...
