Single-color two-photon spectroscopy of Rydberg states in electric fields [PDF]

open access: yes, 2014
Rydberg states of atomic helium with principal quantum numbers ranging from n=20 to n=100 have been prepared by non-resonance-enhanced single-color two-photon excitation from the metastable 2 {^3}S{_1} state.

Mass transfer intensification for carbon quantum dot nanofluid drops under pulsed electric fields

open access: yesScientific Reports, 2022
Simultaneous use of carbon quantum dot (CQD) nanofluids and pulsed electric fields exhibits amazing mass transfer intensification in liquid–liquid extraction of circulating drops. Here, the chemical system of kerosene–acetic acid–water with mass transfer

Pulsed Power Applications for Protein Conformational Change and the Permeabilization of Agricultural Products

open access: yesMolecules, 2021
Pulsed electric fields (PEFs), which are generated by pulsed power technologies, are being tested for their applicability in food processing through protein conformational change and the poration of cell membranes. In this article, enzyme activity change

Coupling Rydberg atoms to microwave fields in a superconducting coplanar waveguide resonator [PDF]

open access: yes, 2020
Rydberg helium atoms traveling in pulsed supersonic beams have been coupled to microwave fields in a superconducting coplanar waveguide (CPW) resonator. The atoms were initially prepared in the 1s55s $^3$S$_1$ Rydberg level by two-color two-photon laser ...

Transient features in nanosecond pulsed electric fields differentially modulate mitochondria and viability. [PDF]

open access: yesPLoS ONE, 2012
It is hypothesized that high frequency components of nanosecond pulsed electric fields (nsPEFs), determined by transient pulse features, are important for maximizing electric field interactions with intracellular structures.

Dielectric fluid in inhomogeneous pulsed electric field [PDF]

open access: yesPhysical Review E, 2013
We consider the dynamics of a compressible fluid under the influence of electrostrictive ponderomotive forces in strong inhomogeneous nonstationary electric fields. It is shown that if the fronts of the voltage rise at a sharp, needle-like electrode are rather steep (less than or about nanoseconds), and the region of negative pressure arises, which can
