Force Dependence of Transition Rates in Atomic Friction
Physical Review Letters, 2006The lateral forces during stick-slip motion of an atomic force microscope cantilever on highly oriented pyrolytic graphite are measured and analyzed. We identify the regimes where thermally activated interstitial hopping of the cantilever tip proceeds according to a single-step reaction scheme and extract the corresponding force-dependent transition ...

Rate of Recombination of Nitrogen Atoms
The Journal of Chemical Physics, 1958The rate of recombination of nitrogen atoms by three-body collision has been determined at room temperature and 0.5–1.3 mm pressure. The nitrogen was dissociated (about 3–6% nitrogen atoms) in a condensed discharge and pumped continuously through a glass tube 4.2 cm i.d. and 2.5 m long.

Efficient capture of fine particulate matters by ultrasonic atomization
Journal of Environmental Chemical Engineering, 2021In order to achieve efficient capture of fine particulate matters (the aerodynamic equivalent diameter between 0.01 and 5 µm), fiber filter dust removal equipment was employed. Ultrasonic atomization technology was used to improve the existing filtration

Rate of aerodynamic atomization of droplets
Journal of Spacecraft and Rockets, 1965A TOMIZATION of large liquid droplets subjected to high ^J^relative gas velocities is of interest to the field of liquid propellant combustion and instability processes, which occur in rocket engines. It is desirable to have quantitative information for the time rate of mass loss from the droplet as a function of the gas stream and droplet ...

Effects of nonequilibrium plasmas on atomic reaction rates
Physical Review E, 1994The influence of electron-density fluctuations on atomic reaction rates is studied in a hydrogen model plasma. We show that the effective ionization rates are found to be extremely sensitive to deviations of the electron density from the local thermal equilibrium (LTE) distribution, while the effective recombination rates are relatively stable against ...

Rate of recombination of nitrogen atoms
The Journal of Chemical Physics, 1979Decays of the concentration of N(4S) atoms in the Lewis–Rayleigh nitrogen afterglow were measured in a static mode, with a mass spectrometer that was calibrated against NO titration. The rate constant for recombination of N(4S) atoms with N2 molecules as the third body [N(4S)+N(4S)+N2→N2+N2] was determined as 7.2×10−33 cm6 molecule−2 sec−1.

Electrospray modes of liquids in electrohydrodynamic atomization: A review
The Physics of FluidsLiquid is sprayed from a capillary tube and further disperses into fine drops in various means, when subjected to an externally electric field, where the process of liquid jet formation and breakup into drops is usually named as electrohydrodynamic ...
