This in vitro study used spectroscopic and conductometry methods to examine binding between human hemoglobin and an angiotensin-converting enzyme inhibitory peptide, with and without electromagnetic field (EMF) exposure. The authors report that EMF changed the Hb–ACEIP interaction and that binding was associated with…

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 deposited Ga-doped ZnO thin films via radio frequency sputtering and examined how Ga content affects optoelectronic properties and electrical stability. The abstract reports non-monotonic changes in conductivity with increasing Ga content alongside degraded crystallinity, while maintaining >80%…

This materials study examined how growth rate and an external magnetic field affect microstructure and properties in directionally solidified Ag-Cu eutectic alloys. The lamellar spacing followed the Jackson-Hunt model with a reported constant of 5.8 µm³/s. Increasing magnetic field tilted eutectic growth and…

This conference paper describes a peri-implantitis therapy using radio frequency electric current and presents numerical simulations alongside referenced clinical evidence. The abstract reports 81% successful treatment across 66 implants in 46 patients. FEM modeling suggests current preferentially concentrates in…

This computational study used finite element modeling to estimate the electric field distribution in the brain during tDCS for two electrode montages targeting the left DLPFC. It systematically varied isotropic tissue conductivity profiles to assess sensitivity of predicted E-field magnitude and components in the…

This laboratory/analytical study examined how sample matrix affects sample sweeping in micellar electrokinetic chromatography under an inhomogeneous electric field. It reports strong focusing for hydrophobic cationic analytes when the sample matrix conductivity is much higher than the BGE, even with low surfactant…

The paper reviews and analyzes mechanisms for resonance action of extremely weak alternating magnetic fields (40 nT) combined with weak static fields (40 μT), tuned to cyclotron frequencies.

This engineering study investigated factors affecting electro-dewatering of activated sludge under a horizontal applied electric field. It reports optimal performance without altering sludge pH or conductivity and finds that CPAM conditioning improves and accelerates dewatering. The authors provide operating…

This paper proposes that Pb nanowires created by repeated indentation of a Pb tip on a Pb substrate may exhibit topological superconducting properties in an external magnetic field.

This experimental and modeling study examined pulsed electric field (PEF) permeabilization in several fruit and vegetable tissues at 293 K using 1000 μs pulses and field strengths of 400 and 1000 V·cm(-1). While electroporation theory predicts greater damage in tissues with larger cells, the authors report this…

This paper presents a theoretical model of giant phospholipid vesicle deformation in an alternating-current electric field, based on minimizing membrane bending energy and electric-field energy.
