The cross section for neutron interactions on argon is an important design and operational parameter a number of neutrino, dark matter, neutrinoless double beta decay experiments which use liquid as detection or shielding medium. There discrepancy between the evaluated total in 20 to $70\phantom{\rule{4pt}{0ex}}\mathrm{keV}$ kinetic energy region given ENDF database single measurement conducted...

Molecular dynamics and DSMC models for energy transfer in argon dimer argon monomer collisions are compared. The inelastic collision number for these collisions is evaluated, and found to decrease significantly when gas temperature increases.

The gaseous atmosphere plays a major role in the quality of manufactured parts Laser Powder Bed Fusion (L-PBF) by protecting metal from high temperature oxidation. If argon and nitrogen are most commonly used gases, helium has almost never been considered as possible candidate chemically inert shielding gas. To provide better understanding influence gas on process stability, comparative study L...

OBJECTIVE As the contamination of implant surface seriously affects the early osseointegration of implants and reduces the survival rate of implants, it has attracted wide attention of researchers. The most oral titanium implants used in current clinical applications are stored in sealed packages. During the process of packaging, storage and usage, the implants inevitably contact air, which res...

Welding method and its parameters has an important effect on the formability and mechanical properties of tailor welded blanks(TWBs). In this study gas tungsten arc welding(GTAW) is used to joint aluminum TWBs. Aluminum TWBs consist of 6061 aluminum sheets with different thickness of 1mm and 2mm. Main parameters of GTAW consist of welding current, pressure of shielding gas, welding speed and di...

Three-dimensional finite-volume-based numerical models of fluid, heat, and mass transport have been developed and applied to help explain the complex inter-related phenomena of multiphase fluid flow, superheat dissipation, and grade intermixing during the continuous casting of steel slabs. Gas bubbles are simulated using a continuum model, which calculates the volume fraction and velocities of ...

An absolute shielding scale is proposed for (207)Pb nuclear magnetic resonance (NMR) spectroscopy. It is based on ab initio calculations performed on an isolated tetramethyllead Pb(CH3)4 molecule and the assignment of the experimental resonance frequency from the gas-phase NMR spectra of Pb(CH3)4, extrapolated to zero density of the buffer gas to obtain the result for an isolated molecule. The ...
