Electropulse Processing of Gold-Bearing Ore
Materials Science Forum, 2016Experimental results for nanosecond electromagnetic impulses (NEMI) impact on precious metals leaching process from sulphidic ores are presented. A possibility of an intensification of leaching process of Au, Ag, Cu is established. The extraction of silver increases by 70 %, gold – by 40 %. The samples of sulphidic ores from the pit of JSC NPF "Bashkir

Electropulsation, an biophysical delivery method for therapy
2007Electropulsation is the direct delivery of electric pulses on cells to brings a targeted permeabilization of the membrane. This can be used in vivo by the direct field delivery on the patient following the injection of the drug or nucleic acid. This appears as a promising biophysical method for gene therapy. Limits and unknowns will be outlined in this

Electropulse Responsivity to Changes in Skin Moisture
Perceptual and Motor Skills, 196712 Ss were exposed to electropulse stimulation under 3 moisture treatments: dry, water immersion, and a fluid approximation of sweat. Touch threshold data were obtained under these conditions during the first half of the experiment and electropulse recognition responses during the second half.

Membrane and actin reorganization in electropulse-induced cell fusion
Journal of Cell Science, 2013When cells of Dictyostelium discoideum are exposed to electric pulses they are induced to fuse, yielding motile polykaryotic cells. By combining electron microscopy and direct recording of fluorescent cells, we have studied the emergence of fusion pores in the membranes and the localization of actin to the cell cortex.

Material Electropulsing Treatment and Characterisation of Machinability
2017The machinability of metals and alloys is well known for being affected by the cutting conditions, cutting tools and material properties. A very high-quality surface finish can be obtained by the use of advanced machine tools based on single point diamond turning (SPDT).

Influence of electropulsing on nucleation during phase transformation
Journal of Materials Research, 2002Phase transformation about precipitation in a Cu–Zn alloy was studied. It was found that with an electropulsing treatment the number of nuclei during phase transformation could be dramatically enhanced and nucleation of precipitates was more homogeneous.

Using Electropulsing to Control the Surface Quality of Casts
Materials Science Forum, 2023This paper reports on the mechanisms and provides worked examples of using pulsed electric current to improve the surface properties of conductive materials during solidification. A rough surface is formed via the freezing of thermomechanical fluctuations and external disturbances during solidification. Pulsed electric current provides an extra driving

Direct monitoring of the field strength during electropulsation
Bioelectrochemistry and Bioenergetics, 1998Abstract The field strength which is applied on the sample during electropulsation can be affected by electrochemical process at the level of the electrodes. A previous study [U. Pliquett, E.A. Gift, J.C. Weaver, Determination of the electric field and anomalous heating caused by exponential pulses with aluminium electrodes in electropulsation ...

siRNA Delivery via Electropulsation: A Review of the Basic Processes
2014Due to their capacity for inducing strong and sequence specific gene silencing in cells, small interfering RNAs (siRNAs) are now recognized not only as powerful experimental tools for basic research in Molecular biology but with promising potentials in therapeutic development. Delivery is a bottleneck in many studies.
