Ultrashort electric pulse induced changes in cellular dielectric properties

, 2007
The interaction of nanosecond duration pulsed electric fields (nsPEFs) with biological cells, and the models describing this behavior, depend critically on the electrical properties of the cells being pulsed.

Study on the Influence of Temperature, Moisture and Electric Field on the Electrical Conductivity of Oil-Impregnated Pressboard

Energies, 2019
The main insulation of converter transformers consists of transformer oil and oil-impregnated pressboard. Under operating conditions, the valve-side winding of the converter transformer is subject to DC voltage components.

Non‐linear electrical conductivity of ethylene‐propylene‐diene monomer‐based composite dielectrics by tuning inorganic fillers

High Voltage, 2023
In this study, three kinds of inorganic fillers are chosen and filled into ethylene‐propylene‐diene monomer (EPDM) matrix, including silicon carbide, copper calcium titanate (CCTO), and vanadium dioxide (VO2).

On the relationship between auroral absorption, electrojets currents and plasma convection [PDF]

, 2009
In this study, the relationship between auroral absorption, electrojet currents, and ionospheric plasma convection velocity is investigated using a series of new methods where temporal correlations are calculated and analysed for different events and ...

Measurement Method of Physical Parameters of Two-Phase Flow Based on Dual-Frequency Demodulation

Sensors, 2023
Oil-water two-phase flow commonly occurs in the process of crude oil electric dehydration. Here, through dynamic changes in the water content and conductivity of oil-water two-phase flow in the process of electric dehydration, the influence of water ...

Decrease of the electric field penetration into the ionosphere due to low conductivity at the near ground atmospheric layer [PDF]

Annales Geophysicae, 2010
It is well known that lithospheric electromagnetic emissions are generated before earthquakes occurrence. In our study, we consider the physical penetration mechanism of the electric field from the Earth's surface, through the atmosphere-ionosphere ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
