ASSESSMENT OF THE SYNTHESIS ROUTES CONDITIONS FOR OBTAINING AMMONIUM DINITRAMIDE BY THE FT-IR. DOI: 10.5028/jatm.2011.03033311

Journal of Aerospace Technology and Management, 2012
Over the last two decades, many routes have been proposed to synthesize ammonium dinitramide (ADN). However, most of them lie in routes in which reactants are too expensive for large-scale production.

Experimental Study on the Effect of Swirling Flow and Oxidizer Type on the Stability, Light Emission, and Pollutant Emissions of Non-Premixed Propane Flames [PDF]

Journal of Applied and Computational Mechanics
This experimental study examines the effects of swirling oxidizer flow and oxidizer type (air vs. oxygen) on non-premixed propane flames in a vane-type swirl burner. Using swirler angles of 30°, 45°, and 60°, we investigated flame stability limits, light

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

Advanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Low‐Cost, Large‐Scale Nanoporous Metals by Mechanical Alloying, Oxide Reduction, and Dealloying of Powders

Advanced Engineering Materials, EarlyView.
Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...

Formation of Soot in Oxygen-Enriched Turbulent Propane Flames at the Technical Scale

Energies, 2020
Soot is an important component for heat transfer in combustion processes. However, it is also a harmful pollutant for humans, and strict emissions legislation motivates research on how to control soot formation and release. The formation of soot is known
