Structural properties and enthalpy of formation of magnesium hydride from quantum Monte Carlo calculations [PDF]
, 2008 We have used diffusion Monte Carlo (DMC) calculations to study the structural properties of magnesium hydride (MgH$_2$), including the pressure-volume equation of state, the cohesive energy and the enthalpy of formation from magnesium bulk and hydrogen gas.

Autoigniton of n-Butanol at Low to Intermediate Temperature and Elevated Pressure [PDF]
arXiv, 2017 Autoignition delay experiments were performed for n-butanol in a heated rapid compression machine. Experiments were performed at pressures of 15 and 30 bar, in the temperature range 650-900 K, and for equivalence ratios of 0.5, 1.0, and 2.0. Additionally, the initial fuel mole fraction and initial oxygen mole fraction were varied independently to ...

New Directions, 2010 In every area of science there are some ideas that many students find difficult to grasp. A lack of understanding of key ideas can limit a student‟s ability to grasp and apply fundamental principles of their discipline. Previous work in this area, by Taber, has focused on this problem at school level.

Powder Metallurgy and Additive Manufacturing of High‐Nitrogen Alloyed FeCr(Si)N Stainless Steel
Advanced Engineering Materials, EarlyView.The alloying element Nitrogen enhances stainless steel strength, corrosion resistance, and stabilizes austenite. This study develops austenitic FeCr(Si)N steel production via powder metallurgy. Fe20Cr and Si3N4 are hot isostatically pressed, creating an austenitic microstructure.
