One-dimensional radiation-hydrodynamic simulations of imploding spherical plasma liners with detailed equation-of-state modeling [PDF]
Physics of Plasmas 19, 102701 (2012), 2012 This work extends the one-dimensional radiation-hydrodynamic imploding spherical argon plasma liner simulations of T. J. Awe et al. [Phys. Plasmas 18, 072705 (2011)] by using a detailed tabular equation-of-state (EOS) model, whereas Awe et al. used a polytropic EOS model.

Cavitation Erosion Resistance of Additively Manufactured Materials
Chemical Engineering &Technology, Volume 46, Issue 1, Page 37-44, January 2023., 2023 Cavitation‐induced wear can be found in many fluid power components. The effects of additively manufactured materials on the resistance to cavitation erosion were investigated, compared to conventional manufacturing. Mass loss and the surface structure were measured as the main indicators of cavitation erosion.

A cryogenic beam of refractory, chemically reactive molecules with expansion cooling [PDF]
Phys. Chem. Chem. Phys. 13, 18976-18985 (2011), 2011 Cryogenically cooled buffer gas beam sources of the molecule thorium monoxide (ThO) are optimized and characterized. Both helium and neon buffer gas sources are shown to produce ThO beams with high flux, low divergence, low forward velocity, and cold internal temperature for a variety of stagnation densities and nozzle diameters. The beam operates with

Variable Legionella Response to Building Occupancy Patterns and Precautionary Flushing
Microorganisms, 2022 When stay-at-home orders were issued to slow the spread of COVID-19, building occupancy (and water demand) was drastically decreased in many buildings. There was concern that widespread low water demand may cause unprecedented Legionella occurrence and ...
