This paper describes an in vitro gene transfection technique termed water-in-oil droplet electroporation, using an intense DC electric field to deform a droplet between electrodes. The deformation can cause an instantaneous short circuit, during which transient membrane pores are reported to form and permit exogenous…

This engineering study reports optical and electrical characteristics of photonic gel cells made from a PS-b-P2VP lamellar film and a hydrogel electrolyte on ITO glass. Applying 2 V between two facing electrodes over 30 minutes shifted the device reflectance peak from 538 nm up to 604 nm with limited bandwidth…

This paper proposes and simulates actively-controlled second harmonic generation in a silicon nitride ring resonator. Quasi-phase matching is induced by a periodic static electric field generated by voltage applied to electrodes along the ring. Simulations report a calculated efficiency of -21.67 dB at 60 mW pump…
