The NASA MESSENGER mission revealed that lavas on Mercury are enriched in sulfur (1.5-4 wt.%) compared with other terrestrial planets (<0.1 wt.%), a result of high S solubility under its very low oxygen fugacity (estimated O2 between IW-3 and IW-7). Due to decreasing O availability at...

The Physical and Chemical Properties of Minerals are the characteristics that help in identifying and understanding minerals. Physical properties include observable traits like color, luster, hardness, cleavage, and density. Chemical properties refer to the mineral's composition and reactivity, such as ...
The chemical and physical properties of exhaust particles produced by a Caterpillar 3176 C-12 heavy duty diesel engine equipped with a catalytic trap (CRT) are reported. The engine was operated at 600 Nm and 1500 rpm, using fuels containing 15 and 49 ppm sulfur. A two-stage dilution tunnel...
Most steel produced today is plain carbon steel or simply carbon steel. The carbon in steel exists in the iron carbide state. Other elements, among them sulfur, phosphorus, manganese and silicon, are present as well. Carbon Content of Steel ...

Schematic configuration of a LSB cell using the Janus interlayer with two functional surfaces (ZnPTz/f-CFP). Full size image This design aims to use the front side of f-CFP with high electrical conductivity for reducing the charge transfer resistance of the sulfur cathode and the -OH and -...
Tetrasulfur tetranitride, S4N4, reacts with elemental Cu within inert solvents to a black-blue material of approximate composition Cu7S4N4 which is totally amorphous to X-rays and which cannot be made crystalline by either thermal treatment or electron radiation. Cu7S4N4 explodes if heated...
to predict 12 physical and chemical soil properties: organic carbon (OC), inorganic carbon (IC), total carbon (TC), total nitrogen (Tn), clay, silt, sand, Mehlich-3 extractable phosphorus (P), nH4OAc extractable potassium (k), cation exchange capacity (CeC), total sulfur (TS), and pH...
The population balance equations (PBE) were used to describe the variation of size spectrum of fine particulate matter, and the respective contributions of the physical aggregation rate and the chemical growth rate. The PBE model is solved using the adjustable direct quadrature method of moments (...
