Particle‐Scale Mechanics of a Regolith‐Type Soil
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT The existing studies have reported that the surface of Mars shows the presence of materials having igneous origin, including basalt and regolith‐type coarse soils. These findings are affected by significant uncertainties and, therefore, the selection of simulants for various exploration applications, including surface mobility of rovers ...

Prospects of Eliminating Fluorspar Consumption in a Sustainable Argon‐Oxygen‐Decarburization Process
steel research international, EarlyView.This study aims at identifying pathways for eliminating fluorspar consumption in the argon‐oxygen‐decarburization (AOD) process. Thermodynamic calculations suggest the feasibility of completely replacing fluorspar with alternative fluxes such as Al2O3, Na2O, K2O, and Li2O of suitable amounts.

Feldspar crystallisation in felsic magmas: a review
, 1992 Understanding the controls on the evolution of natural feldspars is greatly assisted by coupling experimental determinations of feldspar/melt equilibria with thermodynamic modelling and the calculation of crystallisation paths.

Environmental Toxicology, EarlyView.ABSTRACT Natural radionuclides in cement and gypsum production materials pose significant risks of occupational radiation exposure that are not well documented in Iraqi Kurdistan. This study quantifies alpha and gamma radiation levels from naturally occurring radioactive materials, specifically 222Rn, 238U, 232Th, and 40K, in cement and gypsum samples ...
