Applications

Cold Plasma for air purification

Air purification using pulsed cold plasma is a promising technique that utilizes the antimicrobial and oxidizing properties of plasma to clean and sanitize the air we breathe.

Pulsed cold plasma air purifiers work by creating a high-energy plasma discharge in the presence of air. The pulsed power generates reactive species, such as ozone, hydrogen peroxide, and free radicals, which effectively neutralize and eliminate airborne pollutants, including bacteria, viruses, mold spores, and volatile organic compounds (VOCs). Additionally, the electric field associated with the plasma discharge can induce charges on particulate matter, causing them to agglomerate and settle, leading to cleaner air.

One of the advantages of using pulsed cold plasma for air purification is that it can operate at room temperature, unlike traditional hot plasma methods. This makes it a safer and more energy-efficient option for air purification systems.

The pulsed corona discharge is an efficient means to generate cold plasma for air purification. It is particularly well-suited for air purification because it can generate high concentrations of reactive species, such as ozone and free radicals, without significantly increasing the temperature of the surrounding air.

Typically, the voltage range shall be in the range of tens of kV and the pulse duration in the range of tens to a few hundreds of nanoseconds, stopping the ionisation process before the current starts to circulate between the electrodes of the discharge plasma element.

Montena designs new technologies based on solid state switching for its new set of fast voltage pulsers, especially well-suited for these applications. Thanks to their modular architecture the generators of montena can deliver a large range of pulse intensity and duration.

Nanosecond pulsed electric field for stimulation of cells

Nanosecond Pulsed Electric Field (nsPEF) is an electrostimulation technique based on the delivery of high intensity very short electric field pulses.

When applied to living cells or tissues, the high intensity very short field pulses do not cause the death of the cells by apoptosis but create a stress which stimulates the differentiation and / or proliferation processes.

Such effects are of great interest to accelerate seed germination, increase the cell proliferation rate, improve plant growth, or use new medical applications for wound healing or cancer treatment.

Montena designs new pulse generators based on solid state switching, specially designed for nanosecond pulsed electric field (nsPEF) applications.

Thanks to a modular architecture the pulses of montena can deliver a large range of pulse intensity and duration.

Nanosecond pulsed electric fields in medical applications

Nanosecond pulsed electric fields (nsPEFs) have been primarily investigated for the potential of reversible electroporation in cancer therapy. It also open the doors for new medical treatments, for precise drugs deliveries, for genetics, for research, etc.

Specs have been studied as a potential modality for tumor ablation and targeted cancer treatment. Similar to microsecond pulsed electric fields (msPEFs), nsPEFs can induce irreversible electroporation in tumor cells, leading to cell death. However, nsPEFs may offer advantages in terms of improved selectivity, reduced thermal effects, and potentially enhanced immune response compared to msPEFs.

nsPEFs have shown potential in promoting wound healing processes. Studies have suggested that nsPEFs can enhance cell migration, stimulate angiogenesis (formation of new blood vessels), and modulate the expression of growth factors and cytokines involved in wound healing.

To be reversible, the electroporation process is based on an exposure of the living cells to a very intense electric field (in the range of tens of kV/m) but for a very short duration (in the range of tens to a few hundred nanoseconds).

Montena designs new pulse generators based on solid state switching that are specially designed for nanosecond pulsed electric field (nsPEF) applications.

Thanks to a modular architecture the pulsers of montena can deliver a large range of pulse intensity and duration.

Plasma activated water

When water is treated with plasma, it undergoes significant chemical and physical transformations. The plasma discharge breaks down water molecules, resulting in the formation of reactive oxygen and nitrogen species. These species exhibit strong oxidative and reductive properties, enabling them to attack and neutralize pathogens, bacteria, and other harmful substances. The antimicrobial activity of plasma-activated water makes it an attractive alternative to traditional disinfection methods, as it can effectively kill bacteria, viruses, and biofilms without the use of chemicals or antibiotics.

Moreover, plasma-activated water has shown potential in promoting plant growth and crop protection in agriculture. It can be used as a foliar spray or irrigation solution to enhance seed germination, improve nutrient absorption, and control plant diseases. The ionization created by a cold plasma in a combination of air + water creates fertilizers and disinfectants.

Pulsed corona is an efficient way to generate cold plasmas. In this technique, short-duration, high-energy pulses of electrical power are applied to a gas, typically at atmospheric pressure. These pulses rapidly ionize and excite the gas molecules, creating a plasma state. The advantage of using pulsed power for generating cold plasma is that it allows for precise control of plasma parameters such as density, temperature, and composition. By adjusting the pulse duration, amplitude, and repetition rate, it is possible to tailor the plasma characteristics to suit specific applications. It is possible to optimize the generation of fertilizer and or disinfectant.

Typically, the pulse voltage shall be in the range of tens of kV and the pulse duration in the range of tens to a few hundred nanoseconds, stopping the ionization process before the current starts to circulate between the electrodes of the discharge plasma element.

Montena designs new pulse generators based on solid state switching, which is especially designed for nanosecond pulsed corona plasma generation.
