Single crystals of Co(3)(PO(4))(2)·H(2)O, tricobalt(II) bis-[ortho-phosphate(V)] monohydrate, were obtained under hydro-thermal conditions. The compound is the second polymorph of this composition and is isotypic with its zinc analogue, Zn(3)(PO(4))(2)·H(2)O. Three independent Co(2+) cations are bridged by two independent orthophosphate anions. Two of the metal cations exhibit a distorted tetra...

We determine the 2-modular character table of the third sporadic simple group of Conway, up to two ambiguities. In each of these cases we give the smallest possibility for the character, which is also very likely to be the correct answer.

In previous dissolution studies, dolomite has been commonly assumed to have an ideal composition of CaMg(CO3)2. The objectives this work are determine (1) if dolomites composing hydrocarbon reservoir rocks vary in chemical composition, specifically Ca content, and (2) the effect uptake on rate HCl acid. Dolomitic from different sources were analyzed using several techniques, including: X-ray di...

Ferromagnesite (Mg,Fe)CO3, also referred to as magnesiosiderite at high iron concentration, is a solid solution of magnesite (MgCO3) and siderite (FeCO3). believed enter the Earth's lower mantle via subduction considered major carbon carrier in mantle, playing key role deep cycle. Experiments have shown that ferromagnesite undergoes pressure-induced spin crossover, accompanied by volume elastic...

This research was conducted to examine the drinking (WQI1) and irrigation (WQI2) water quality for Bhavani river basin using statistical methodologies. The study area geographically covers up 4207 km2. For evaluating Water Quality Index (WQI), fourteen groundwater parameters were employed data gathered two decades (1972–1990 & 2010–2019). include TDS, pH, EC, TH, Ca2+, Mg2+, Na+, K+, CO3 2-...
