In line with the wider application of non-contact voltage transducers in the engineering field, transducers are required to have better performance for different measuring environments. In the present study, the D-dot voltage transducer is further improved based on previous research in order to meet the requirements for long-distance measurement of electric transmission lines. When measuring th...

The liquid crystal mixture E7, based on cyanobiphenyl, has been successfully employed to map electric field strength and distribution in AlGaN/GaN high electron mobility transistors. Using a transmitted light image through crossed polarizers the optical response of the liquid crystal deposited onto the surface of the devices was recorded as a function of source–drain bias, Vds. At a critical vo...

introduction:  electroporation  is  a  technique  for  increasing  the  permeability  of  the  cell  membrane  to  otherwise  non-permeate  molecules  due  to  an  external  electric  field.  this  permeability  enhancement  is  detectable if the induced transmembrane voltage becomes greater than a critical value which depends on the  pulse  strength  threshold.  in  this  study,  the  variabil...

Gel electrophoresis allows to separate knotted DNA (nicked circular) of equal length according to the knot type. At low electric fields, complex knots being more compact, drift faster than simpler knots. Recent experiments have shown that the drift velocity dependence on the knot type is inverted when changing from low to high electric fields. We present a computer simulation on a lattice of a ...

Electrical heating of the graphite die and punch assembly is a unique feature of the spark plasma sintering (SPS) process. The high currents needed to heat the die, despite its low resistance, can produce an electric field across the ceramic specimens that may be enough to induce field assisted sintering. Despite the large number of publications of SPS, the electric field intensity has not been...

the effects of pulsed electric field (pef) on the cell disintegration of sugar beet were studied. field strength (0.5kv/cm to 6kv/cm), pulse number (1 to 100 pulses) and capacity of capacitors (0.5 f to 32 f) were evaluated on degree of cell disintegration and consumed energy in pef treatment. the field conditions of 1 and 2 kv/cm, 8 f with 20 and 10 pulses respectively disintegrated the cel...
