FeS is Modderite-like structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are twelve inequivalent Fe2+ sites. In the first Fe2+ site, Fe2+ is bonded to six S2- atoms to form a mixture of distorted edge, corner, and face-sharing FeS6 octahedra. The corner-sharing octahedra tilt angles range from 33–65°.

Ein Mineral (aus mittellat. aes minerale „Grubenerz“, im 16. Jahrhundert nach französischem Vorbild geprägt) ist im Gegensatz zum Gestein ein einzelnes Element oder eine einzelne chemische Verbindung, die im Allgemeinen kristallin und durch geologische Prozesse gebildet worden ist. Der Plural lautet Minerale (in der Wissenschaft in Deutschland und Österreich verwendet) oder Mineralien ...

Materiel or Material? It is not uncommon to see the word material where materiel should have been used. It is also not uncommon for people to think the word materiel is a spelling mistake of material. A Video Summary Here is a 2-minute video summarizing the difference between material and materiel.

Mineralogy is a subject of geology specializing in the scientific study of the chemistry, crystal structure, and physical (including optical) properties of minerals and mineralized artifacts.Specific studies within mineralogy include the processes of mineral origin and formation, classification of minerals, their geographical distribution, as well as their utilization.

Australia is the largest producer of bauxite, followed by China. In 2017, China was the top producer of aluminium with almost half of the world's production, followed by Russia, Canada, and India. Although aluminium demand is rapidly increasing, known reserves of its bauxite ore are sufficient to meet the worldwide demands for aluminium for many centuries.

Georgius Agricola is considered the 'father of mineralogy'. Nicolas Steno founded the stratigraphy (the study of rock layers (strata) and layering (stratification)), the geology characterizes the rocks in each layer and the mineralogy characterizes the minerals in each rock. The chemical elements were discovered in identified minerals and with the help of the identified elements the mineral ...

Materials Chemistry and Mineralogy is an international postgraduate study program covering application related topics ranging from raw materials to industrial products. The curriculum is divided into a general mandatory part and an elective part focusing on either chemistry or mineralogy.

Electroreduction of CO 2 to CO is one of the simplest ways to valorise CO 2 as a source of carbon. Herein, a cheap, robust, Cu‐based hybrid catalyst consisting of a polymer of Cu phthalocyanine coated on carbon nanotubes, which proved to be selective for CO production (80 % faradaic yield) at relatively low overpotentials, was developed.
