Agriculture

EHT power systems can produce nonthermal plasma (NTP) for the agricultural sector. NPTs are an eco-friendly alternative to conventional agrochemical treatments used in pre- and post-harvest. They can remove pesticides and contaminants from the seed surface, increase the shelf life of crops, improve germination, and enhance resistance to abiotic stress. Pre-treatment of seeds and seedlings…

Surface Modification

EHT power systems can be used for plasma surface activation, which modifies the chemical properties of the surface. The high-energy particles in the plasma interact with the surface, breaking the existing chemical bonds and creating new active sites. These active sites can enhance the surface’s reactivity, making it more amenable to bonding with other materials.…

Nanoparticle Production

Nanoparticles can be produced with non-thermal plasmas (NPTs). They can process materials that are difficult or even impossible to handle with other processing schemes, making them particularly useful for the synthesis of a wide range of materials in nanoparticle form. The nonequilibrium environment enables the synthesis of nanocrystals with excellent crystallinity and narrow size distributions.…

Textile Treatment

Nonthermal plasma technology is revolutionizing the textile industry by offering an eco-friendly and efficient alternative to conventional wet chemical processing treatments. This technology is used for surface modification and functionalization of cellulosic fabrics, enhancing their properties without altering their bulk characteristics. The process works at room temperature and generates a large number of chemically reactive…

Thin Films

EHT power systems can be used for a variety of thin film applications including solar and display. Our power systems can be used to bias surfaces to produce directional fluxes of particles for sputtering and evaporation. Additionally, these power systems can be used to produce nonthermal plasmas for atmospheric-pressure plasma-enhanced chemical vapor deposition. These techniques…

Rapid Capacitor Charging

The  5 kW nanosecond pulsers can be modified for rapidly charge larger capacitors. The unit was designed to charge capacitors up to 4 nF in 100 – 300 ns (depending on capacitance). The pulser was tolerant to shorts for up to 3 seconds. Continuous Operation Output Voltage: 0-2 kV Output Capacitance: 0-4 nF Pulse Repetition…

Electroporation

Pulsed electric fields applied to cells can increase the permeability of the cell membrane. Drugs, DNA, nanoparticles, and other chemicals can be introduced into the cell through these temporary pores in the cell membrane. This reversible electroporation requires precision control of the output voltage and pulse widths. Longer pulses and/or higher field strengths can cause…

Nonlinear Transmission Line Driving

The EHT NSP-IA was originally designed for driving nonlinear transmission lines (NLTLs) for high-power microwave generation. NLTLs are constructed of elements or materials with a nonlinear permittivity or permeability, which results in a pulse propagation speed that is voltage or current dependent. When a square pulse with a fast rise time is input into the…
