Mineral
A rock is an aggregate of one or more minerals or mineraloids. Some rocks, such as limestone or quartzite, are composed primarily of one mineral – calcite or aragonite in the case of limestone, and quartz in the latter case. Other rocks can be defined by relative abundances of key (essential) minerals; a granite is defined by proportions of quartz, alkali feldspar, and plagioclase feldspar.

Ethylenediamine | C2H8N2
(14)C-Labeled ethylenediamine (EDA) was accumulated by slices of adult rat cerebral cortex, although the tissue:medium ratios were much lower than those for gamma-aminobutyric acid.EDA uptake was temp-dependent and appeared to take place by both sodium dependent and sodium independent mechanisms. Inhibition studies indicate that ethylenediamine may be …

Research progress on CO2 capture and utilization technology
In general, CO 2 capture technology routes can be divided into three types: pre-combustion capture, post-combustion capture, and oxy-fuel combustion technology (Fig. 2, Table 1).Because pre-combustion capture and oxy-fuel combustion capture technologies require appropriate materials and certain conditions to meet high-temperature requirements, the application …

Pyrite
Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold.The color has also led to the nicknames brass, brazzle, and Brazil, primarily used to refer to pyrite found in coal.. The name pyrite is derived from the Greek πυρίτης λίθος (pyritēs lithos), "stone or mineral which strikes fire", in turn from ...

Potassium
Potassium is the chemical element with the symbol K (from Neo-Latin kalium) and atomic number 19. Potassium is a silvery-white metal that is soft enough to be cut with a knife with little force. Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure. It was first isolated from potash, the ashes of plants, …
