They require a starting current pulse to operate, usually supplied by capacitors. Explosively pumped flux compression generators are used to create ultrahigh magnetic fields in physics and materials science research [1] and extremely intense pulses of electric current for pulsed power applications.
Pulsed-power water treatment is the process of using pulsed, electro-magnetic fields into cooling water to control scaling, biological growth, and corrosion.The process does not require the use of chemicals and helps eliminate environmental and health issues associated with the use and life-cycle management of chemicals used to treat water. [1]
Pulsed field ablation (PFA) is a non-thermal (not using extreme heat or cold) method of biological ablation (removal of structure or functionality) utilizing high-amplitude pulsed (microsecond duration) electric fields to create irreversible electroporation in tissues. [1] [2] It is used most widely to treat tumors or cardiac arrhythmias. [3]
This leads to the definition of an electric field magnitude threshold for electroporation (E th). That is, only the cells within areas where E≧E th are electroporated. If a second threshold (E ir ) is reached or surpassed, electroporation will compromise the viability of the cells, i.e. , irreversible electroporation (IRE).
Energy is typically stored as electric potential energy within capacitors, or in the case of explosive pulsed power, as chemical energy.The stored energy is released over a very short time scale resulting in a large amount of power being delivered to a load which can be used to study high energy density physics phenomena such as Inertial confinement fusion using a Z-pinch, and plasma physics ...
Electric field applied: pulsed Purpose: disruption of subcellular structures Condition: non-uniform electric field Theory: ED performs electromanipulation inside a cell which has compromised cytoskeletons and a detached nuclei. Deradated cells eject cytosolic contents and become "ghosts"(about 1.5 times the normal cell size). Ghosts can be ...

SPS is also used for sintering of carbon nanotubes [11] for development of field electron emission electrodes. Functioning of SPS systems is schematically explained in a video link. [ 12 ] While the term "spark plasma sintering" is commonly used, the term is misleading since neither a spark nor a plasma is present in the process. [ 13 ]
