Energy transfer and kinetics in mechanochemistry
Environmental Science and Pollution Research, 2017Mechanochemistry (MC) exerts extraordinary degradation and decomposition effects on many chlorinated, brominated, and even fluorinated persistent organic pollutants (POPs). However, its application is still limited by inadequate study of its reaction kinetic aspects.

Kinetic energy as a perturbation
Physical Review C, 1982The potential energy V is taken as the unperturbed Hamiltonian and the kinetic energy K is used as the perturbation. As K is a semi-positive definite operator, one may use standard Pade approximants to reconstruct the Brillouin-Wigner functional. It is shown that, while the bare projector (E-V)/sup -1/ is plagued in the complex E plane by the cut which

The Journal of the Acoustical Society of America, 1984
A device for absorbing kinetic energy derived from an element oscillating in a direction parallel to a longitudinal axis of the device. The device has a housing coupled to the oscillating member and defining a chamber bounded by opposite inner end walls and an inner lateral wall of the housing.

Kinetic energy budgets near the turbulent/nonturbulent interface in jets
, 2013The dynamics of the kinetic energy near the turbulent/nonturbulent (T/NT) interface separating the turbulent from the irrotational flow regions is analysed using three direct numerical simulations of turbulent planar jets, with Reynolds numbers based on ...

Kinetic energy of an electron gas
Physical Review B, 1985We derive a simple expression for the correlation part of the kinetic energy of an inhomogeneous electron gas from density-functional theory. We show that in the local density approximation, this expression reduces to the virial theorem result ${t}_{\mathrm{xc}}=3{v}_{\mathrm{xc}}\ensuremath{-}4{\ensuremath{\epsilon}}_{\mathrm{xc}}$. We also derive the

Testing the kinetic energy functional: Kinetic energy density as a density functional
The Journal of Chemical Physics, 2003A new method for defining an energy density for the noninteracting kinetic energy of density functional theory is given. The resulting energy density is a density functional determined completely by the kinetic energy functional itself. Although this method is not constructive, it allows for a direct comparison between exact and approximate functionals

Electrostatic Kinetic Energy Harvesting
2016Harvesting kinetic energy is a good opportunity to power wireless sensor in a vibratory environment. Besides classical methods based on electromagnetic and piezoelectric mechanisms, electrostatic transduction has a great perspective in particular when dealing with small devices based on MEMS technology.

Kinetic Energies in Quantum Solids
Physical Review Letters, 1985We show that the recently measured kinetic energy of atoms in solid helium is substantially larger than expected for even a moderately anharmonic solid. The large kinetic energy is rather an explicit measure of the highly anharmonic nature of solid helium.
