This white paper considers the future of plasma science and technology related to manufacturing modifications plastics textiles, summarizing existing efforts current state‐of‐art for major topics processing techniques. It draws on frontier technologies in order see beyond identify grand challenges which we face following 5–10 years. To progress move forward, highlights enabling design surfaces, coatings materials with non‐equilibrium plasmas. The aim is field textile production using...
In this paper we examined the photocatalytic efficiency of a laser-synthesized colloidal solution ZnO nanoparticles synthesized by laser ablation in water. The average size obtained is about 47 nm. As revealed electron microscopy, other nanostructures were also present solution, especially nanosheets. A degradation UV-irradiated Methylene Blue and Rhodamine B solutions different concentration presence catalyst mass concentrations was studied order to examine their influence on...
Abstract Mycotoxins, the toxic secondary metabolites produced by filamentous fungi, are found in up to 80% of global food and feed crops. Here, we report on complete removal aflatoxin B 1 (AFB ) from artificially contaminated corn kernels with an indirect cold atmospheric pressure plasma (CAP) treatment generated a surface barrier discharge system working ambient air. Surface analysis revealed presence minor changes treated samples, indicating that CAP treatments induced slight oxidation...
Atmospheric mercury measurements carried out in the recent decades have been a subject of bias largely due to insufficient consideration metrological traceability and associated measurement uncertainty, which are ultimately needed for demonstration comparability results. This is particularly challenging gaseous HgII species, reactive their ambient concentrations very low, causing difficulties proper sampling calibration. Calibration atmospheric exists, but barriers reliable calibration most...
With recent technological advances and the growing interest in environmentally friendly fiber production processes, textile industry is increasingly turning to spinning of filaments from recycled raw materials melt process as simplest method chemical fibers. Such processes are more efficient because desired active particles melt-spun together with polymer. The study investigates polyamide 6 (PA 6) fibers modified zinc oxide nanoparticles (ZnO NPs) concentrations ranging 0.1 2.0 wt% extrusion...
One of the driving forces behind development cold plasma sources at atmospheric pressure is an application in biomedical field.In this respect, radio-frequency (RF) jets are particular importance due to possible safe operation on humans and a generation high amount reactive species.For reason, we designed RF jet co-axial geometry with possibility aerosol introduction, where its characteristics were evaluated by electrical diagnostics, optical emission, laser scattering spectroscopy.The...

The possible benefits of an atmospheric pressure plasma jet skin treatment have been tested in vivo on mouse skin. Many studies conducted vitro cells, but only a few where, due to the complexity biological system, can cause severe damages. For this reason, we investigated how kHz generated that is known inflict damage interacts with and explored reduce damage. First, focus was exploring effects formation different gases inclinations. results pointed perpendicular orientation He as most...
For this study, a paper impregnated with silver nanoparticles (AgNPs) was prepared. To prepare the substrates, aqueous suspensions of pulp fines, side product from production, were mixed AgNP suspensions. The nanoparticle (NP) synthesis then carried out via laser ablation pure Ag in water. After sheet formation process, leaching AgNPs determined to be low while sheets exhibited antimicrobial activity toward Escherichia coli (E. coli).
Oriented carbon nanostructures (OCNs) with dominant graphitic characteristics have attracted research interest for various applications due to the excellent electrical and optical properties owing their vertical orientation, interconnected structures, electronic properties, large surface area. Plasma enhanced chemical vapor deposition (PECVD) is considered as a promising method large-scale synthesis of OCNs. Alternatively, structural reformation natural precursor or phenol-based polymers...
The antibacterial and cell-proliferative character of atmospheric pressure plasma jets (APPJs) helps in the healing process chronic wounds. However, control plasma-biological target interface remains an open issue. High vacuum ultraviolet/ultraviolet (VUV/UV) radiation RONS flux from may cause damage a treated tissue; therefore, controlled interaction is essential.

Plasma jets are extensively used in biomedical applications, particularly for exploring cell viability behaviour. However, many experimental parameters influence the results, including jet characteristics, secondary liquid chemistry and protocols used, slowing research progress. A specific interest of presented was skin behaviour under a non-thermal kHz plasma jet—a so-called cold jet—as topical treatment. Our focused on vitro mouse direct treatment with argon as an operating gas. The...
Atmospheric mercury, specifically oxidized mercury (Hg II ), is the largest anthropogenic pool of in atmosphere. This type can accumulate food chain after undergoing methylation and entering ecosystems through wet dry deposition. It important to evaluate level deposition, but measurements atmospheric have been biased due insufficient consideration measurement uncertainty metrological traceability, especially for low ambient concentrations gaseous Hg species. To address this issue, a...
