Applications

Environmental remediation

The highly reactive chemistry of atmospheric pressure low-temperature plasmas makes them particularly suitable for the degradation and removal of pollutants in gaseous and liquid environments. Numerous studies have confirmed the efficacy in reducing VOC (volatile organic compounds such as benzene, toluene and ethylbenzene), bacteria, particulates, NOx and SOx. The advantages of this technology reside in …

Plasma assisted combustion

Studies on the use of atmospheric pressure non-thermal plasmas to ignite and control combustion in internal combustion engines and turbines demonstrate their effectiveness in reducing the ignition timing, with an improvement of engine performance, a lesser presence of unburned and of undesirable combustion products such as CO, NO and NOx; difficulties related to the generation …

Plasma medicine

Under this name go the frontier processes adopting atmospheric pressure cold plasmas for therapeutic purposes, whose effectiveness is linked to the number of active agents (chemical and physical) produced in plasma and to their controllability and whose mechanisms still require in-depth investigation. Among these processes are: sterilization of infected wounds, treatment of chronic wounds, ulcers …

Sterilization

Atmospheric pressure cold plasma has been shown capable of inactivating microorganisms within a few seconds, without altering the characteristics of the material to be sterilized (which can be either in solid, liquid and gaseous phase, and also in the case of artefacts of high historical value) and with the possibility to be adapted for the …

Surface modification

Atmospheric pressure cold plasma offers an innovative, cost-effective and eco-friendly solution for the support of several processes: deposition of organic or inorganic coating (e.g. polymer, silica-like coating, anti-scratch films), modification of packaging barrier properties and activation of materials (e.g. polymers, metals), thus increasing their surface energy to facilitate gluing and to improve printability, avoiding the …

Nanomaterials and composites

Plasma technology is widely used in the production of metal (e.g. Al, Fe, Si) and ceramic (e.g. Al2O3, SiO2, WC) nanoparticles, carbon-based (e.g. nanotubes, fullerenes, graphene) and innovative nanomaterials (core-shell nanostructures, nanoparticles with surface functionalizations). Unlike traditional processes of wet-chemistry, and ball-milling, plasma technology allows the production of particles with a diameter less than 100 …

Spheroidization for additive manufacturing (AM)

Coarse powders can be subjected to thermal plasma in-flight treatment by injection into the discharge of an induction plasma torch and reaction chamber in order to obtain densification, purification and spheroidization, with a huge increase in powders fluidability that can be successfully used in several additive manufacturing (AM) applications. This treatment can be applied to …
