    Abstract

    Several studies have documented that treatment by cold atmospheric pressure plasma (CAPP) on plants foster seed germination and growth in recent years. However, the molecular processes that underlie the action of CAPP on the seeds and plants remain mostly enigmatic. We here introduce gemmae of Marchantia polymorpha, a basal liverwort, as a novel model plant material suitable for CAPP research. Treating the gemmae with CAPP for a constant time interval at low power resulted in consistent growth enhancement, while growth inhibition at higher power in a dose-dependent manner. These results distinctly demonstrate that CAPP irradiation can positively and negatively regulate plant growth depending on the plasma intensity of irradiation, offering a suitable experimental system for understanding the molecular mechanisms underlying the action of CAPP in plants.

    The current research focuses on carbon dioxide (CO2) conversion at ambient conditions using streamer plasma. In this study, treatment time and humidity have been found to influence CO2 conversion. Our findings reveal a maximum CO2 conversion rate of 35.2%, achieved with a remarkably high energy efficiency of CO2 conversion at 135% and a low energy cost of 2.17 eV/molecule. We employed optical emission and fourier-transform infrared spectroscopy spectroscopy to analyze the different dissociation products of CO2 and determine the percentage of CO2 conversion. Furthermore, we utilized a two-dimensional (2D) fluid dynamics model and a zero-dimensional (0D) chemistry model to gain insights into the reactor mechanism.

    This study provides the health effects assessment of rice cultivated from plasma-irradiated seeds. The rice (Oryza sativa L.) cultivated from seeds with plasma irradiation showed a growth improvement (slope-ratios of with plasma to without plasma were 1.066, 1.042, and 1.255 for tiller, and earing, and ripening periods, respectively) and an 4% increase in yield. The cultivated rice was used for repeated oral administrations to mice for 4-week period. Distilled water and rice cultivated from seeds without plasma irradiation were also used as control. The weights of the lung, kidney, liver, and spleen, with corresponding average values of 0.22 g, 0.72 g, 2.1 g, and 0.17 g for w/ plasma group and 0.22 g, 0.68 g, 2.16 g, and 0.14 g for w/o plasma group, respectively, showing no effect due to the administration of rice cultivated from plasma-irradiated seeds. Nutritional status, liver function, kidney function, and lipid, neutral fat profiles, and glucose metabolism have no significant difference between with and without plasma groups. These results show no obvious subacute effects were observed on rice grains cultivated and harvested from the mother plant that experienced growth improvement by plasma irradiation. This study provides a new finding that there is no apparent adverse health effect on the grains harvested from the plasma-irradiated seeds.

    Abstract

    Plasma irradiation leads not only active species, but also reactive chemical species, ultraviolet light, electric fields, magnetic fields, and shock waves. To date the effects of reactive chemical species have been mainly discussed. To understand the biological effect caused by an electric potential induced with an atmospheric-pressure plasma, the behavior of cell stimulated by electric potential was investigated using HeLa cell. The cell concentration assay revealed that less than 20% of cells inactivated by potential stimulation and the remained cells proliferate afterward. Fluorescent microscopic observation revealed that potential stimulation is appreciable to transport the molecules through membrane. These results show that potential stimulation induces intracellular and extracellular molecular transport, while the stimulation has a low lethal effect. A possible mechanism for this molecular transport by potential stimulation was also shown using numerical simulation based on an equivalent circuit of the experimental system including adhered HeLa cell. The potential formation caused by plasma generation is decisive in the contribution of plasma science to molecular biology and the elucidation of the mechanism underlying a biological response induction by plasma irradiation.

    CO2 methanation is an effective technology for CO2 reduction. Generally, methanation reactions are accelerated using thermal catalysts. However, the temperature control is difficult because CO2 methanation is an exothermic reaction, and the catalyst is deactivated by overheating. Plasma catalysis can solve this problem by driving this reaction at lower temperatures. Therefore, in this study, we investigated the contribution of the active species generated in the plasma to CO2 methanation. We found that the density of active species is linearly related to the power density, and in particular, the CH4 generation rate is determined by the CO-derived active species, not the H-derived active species. Furthermore, with an increase in the catalyst temperature, a new reaction pathway for CH4 production is added. The results of this study contribute to the understanding of the relationship between the active species produced in plasma and CO2 methanation.

    Colossal research on CO2 and N2 conversion using non-thermal plasma (NTP) technology has been ongoing since many years. The primary focus is on CO and NH3 production through CO2 and N2 conversion, respectively, with high conversion efficiency and low energy consumption with or without catalysts. Although in the present study, we propose that the NTP can assist in converting CO2 and N2 to plant nutrients in the form of plasma-treated/activated water. We used a homemade streamer plasma device and produced plasma-activated water (PAW) using CO2 and N2 feed gas, CO2-activated water (CAW) and N2-activated water (NAW). Later, we used CAW and NAW to treat the radish seeds and evaluate the germination rate, germination percentage, and seeding growth. To understand the chemical changes in PAW after the NTP treatment, we performed a chemical analysis to detect NO2¯, NO3¯, NH4+, and H2O2 along with the PAW pH and temperature shift. Additionally, to understand the other species produced in the gas phase, we simulated chemical reactions using COMSOL Multiphysics® software. Our results show that NOx and NHx species are less produced in CAW than in NAW, but CO2-generated PAW offers a significantly more substantial effect on enhancing the germination rate and seeding growth than NAW. Therefore, we suggested that CO and H2O2 formed during CAW production trigger early germination and growth enhancement. Furthermore, the total plasma reactor energy consumption, NO3¯ and NH4+ selective production percentage, and N2 conversion percentage were calculated. To our best knowledge, this is the first study that uses plasma-assisted CO2 conversion as a nutrient for plant growth.

    Methanation of CO2 is a key technology to realize a sustainable society. The reactions should be driven at a lower temperatures from the viewpoint of catalyst stability. Methanation with plasma catalysis can drive reactions at lower temperature than thermal catalysis. However, the reaction mechanism is little understood due to the complexity of the interactions. In this study, we investigated the power and pressure dependence of the methanation efficiency when only plasma is used as a fundamental research. We discuss how these parameters change the vibrational temperature and active species density and affect the methanation efficiency using optical emission spectroscopy.

    Abstract

    We investigated the effects of amplitude modulated (AM) capacitively coupled Ar discharge plasma on the ion energy distribution function (IEDF) and the ion angular distribution function (IADF) incident on electrodes using the particle-in-cell/Monte Carlo collision model. For AM discharge, the electron density and electron temperature and the kinetic energy and angle of ions incident on the ground electrode change periodically with AM frequency, whereas ones for continuous wave discharge are almost constant. For AM discharge, the plasma had hysteresis characteristics. The peak energy of IEDF varies from 53 to 135 eV and the FWHM of IADF varies from 1.82 to 3.34 degrees for gas pressure 10mTorr, the peak-to-peak input voltage 400 V and AM level of 50%. The variation width of the peak energy of IEDF and FWHM of IADF increases with the AM level. These effects of AM method discharge are more noticeable at lower pressures. Thus, the AM discharge offers a way to control simultaneously IEDF and IADF, which opens a new avenue for plasma processes such as an ALD-like PECVD.

    Abstract

    Discharge plasma irradiates seeds with reactive oxygen and nitrogen species (RONS). However, RONS introduced in seeds by plasma irradiation have not been successfully detected thus far. This study provides experimental evidence that nitrate ion NO<sub>3</sub><sup>−</sup> is introduced in lettuce seeds as RONS upon irradiation with atmospheric-pressure air dielectric barrier discharge plasma. Plasma irradiation for 5 min promotes seed germination. The components of the plasma-irradiated seeds were examined using electrospray ionization quantum mass spectrometry (ESI QMS), which revealed that the plasma irradiation introduced an ion with a mass of 62 m/z in detectable amounts. This ion was identified as NO<sub>3</sub><sup>−</sup> by liquid chromatography (LC), multiple wavelength detector (MWD), and LC-ESI QMS. A one-dimensional simulation at electron temperature T<sub>e</sub> = 1 eV, electron density N<sub>e</sub> = 10<sup>13</sup>/m<sup>3</sup>, and gas temperature T<sub>g</sub> = 300 K indicated the introduction of NO<sub>3</sub><sup>−</sup>, involving nitric oxide NO. NO<sub>3</sub><sup>−</sup> is one of the most important ions that trigger signal transduction for germination when introduced in seeds. The scanning electron microscopy (SEM) images revealed that there was no change on the surface of the seeds after plasma irradiation. Plasma irradiation is an effective method of introducing NO<sub>3</sub><sup>−</sup> in seeds in a dry process without causing damage.

    Applicability of precise Raman spectral analysis of a-C:H films deposited using a plasma chemical vapor deposition (CVD) method has been discussed based on the sensitivity to initial conditions in peak separation. The spectral analysis offers to deconvolute the spectra into five peaks, while the as-deposited films prepared by plasma CVD is difficult to the five-peak separation. We found the peak position and the peak height ratio of the D-band to the G(+)-band can be employed to discuss the structure of the as-deposited films. We examined the structural difference between the films deposited at the powered electrode and that at grounded electrode. We found graphene nanoribbon-like structures may be formed in the films deposited on the grounded substrate. This result suggests that the substrate position is an important factor to form the graphene nanoribbon-like structure.

    To meet the needs of the hungry population, it is critical to boost agricultural product production while minimizing contaminated waste. The use of two nonthermal technologies, pulsed electric field (PEF) and nonthermal plasma (NTP), is increasing every day. As both PEF and NTP are relatively newer areas, there is limited knowledge about these two technologies and their modes of action. Studies showed that PEF treatment on the plant seeds helps germination and seedling growth. The positive impact of PEF intensity is highly dependent on the seed coat type and plant species. Another nonthermal technology, NTP, affects seed germination, seedling growth, yield, and resilience to abiotic stress when generated at varying pressures with and without different feed gases. Early germination, germination rate, and germination percentage were all improved when the seedlings were treated with NTP. Similarly to the PEF treatment, NTP had a negative or no effect on germination. This review examined the effects of PEF and NTP on seed germination and ana-lyzed the situation and mechanism behind the positive or negative effect. Deactivation of proteins and enzymes to extend the shelf life of beverages is another prominent application of PEF and NTP. The interaction of PEF and NTP with proteins aids in understanding the microscopic mechanism of these technologies. Therefore, we covered in this review the potential structural and functional changes in proteins/enzymes as a result of PEF and NTP, as well as a comparison of the benefits and drawbacks of these two technologies.

    Nonthermal atmospheric-pressure discharge plasma is considered important for sterilization. Reactive species, such as active oxygen species, radicals, and nitrate ions, generated by the discharge plasma damage the target bacterial cell wall/membrane and DNA. Several plasma sterilization methods have been proposed, including dielectric barrier discharge (DBD). To achieve effective sterilization, it is necessary to evaluate their characteristics using many parameters. This letter aims to demonstrate a proof-of-concept of a novel biological indicator for plasma sterilization. A biological indicator is used to verify sterilization outcomes. We employ DNA-labeled microbeads as biological indicators for the rapid visualization of plasma sterilization. This is based on our recently developed method for visual detection of DNA molecules. If plasma-derived factors cause the degradation of the DNA attached to the microbeads, this can be confirmed by visualization. Herein, we present the correlation between sterilization and visualization in the case of DBD. This method offers a rapid evaluation of plasma sterilization because it easily and quickly determines the sterilization capability of the plasma.

    Abstract

    Large-scale fabrication of thulium iron garnet (TmIG) films on gadolinium gallium garnet (GGG) substrates, with a total area of 25 cm<sup>2</sup>, has been demonstrated by rotating substrate holders during on-axis sputtering. By optimizing the growth parameters based on the pressure and flow rate of the oxygen ratio, a Tm/Fe ratio of 0.65 was obtained, which is close to the stoichiometry of TmIG. The increase in post-annealing temperature has induced the growth of the TmIG structure by the strain of the lattice constant mechanism. At the highest post-annealing temperature, the crystal structure of TmIG (444) and the perpendicular magnetic anisotropy (PMA) were obtained. This result demonstrates the potential method for large-scale fabrication of TmIG film with PMA.

    We have fabricated smooth-surfaced amorphous In2O3:Sn (a-ITO) films at a high temperature of 550 °C, far above the typical crystallization threshold of 150 °C for ITO films. This achievement has been made possible by intentionally introducing N2 into the sputtering atmosphere, which maintains a low N atom incorporation of only a few atomic percent within the films. Positioned within ZONE-T of the Thornton diagram (higher-temperature region characterized by high film density), our method allows the preparation of films with superior film density about 6.96 g/cm3, substantially exceeding the density of 6.58 g/cm3 for conventional a-ITO films fabricated under ZONE-1 (low-temperature region) and approaching the bulk crystal density of In2O3 at 7.12 g/cm3. The films also feature a high carrier density of 5 × 1020 cm−3 and a remarkably low resistivity of 3.5 × 10−4 Ω cm, comparable to those of polycrystalline films. The analysis via vacuum-ultraviolet absorption spectroscopy on N and O atom densities in the plasma suggests that amorphization is primarily caused not by N atoms incorporated in the films but by those temporally adsorbed on the film surface, inhibiting crystal nucleation before eventually desorbing. Our findings will pave the way not only for broader applications of a-ITO films but also for the design of other amorphous materials at temperatures beyond their crystallization points.

    ZnO-AlN pseudo-binary amorphous alloys (a-ZAON hereinafter) with tunable band gaps in the deep ultraviolet (DUV) region have been synthesized using magnetron sputtering. The miscibility gap between ZnO and AlN has been overcome using room-temperature sputtering deposition, leveraging the rapid quenching abilities of sputtered particles to fabricate metastable but single-phase alloys. X-ray diffraction patterns and optical transmittance spectra revealed that the synthesized films with chemical composition ratios of [Zn]/([Zn] + [Al]) = 0.24-0.79 likely manifested as single-phase of a-ZAON films. Despite their amorphous structures, these films presented direct band gaps of 3.4-5.8 eV and thus high optical absorption coefficients (105 cm−1). Notably, the observed values adhered to Vegard’s law for crystalline ZnO-AlN systems, implying that the a-ZAON films were solid solution alloys with atomic-level mixing. Furthermore, atomic force microscopy analyses revealed smooth film surfaces with root-mean-square roughness of 0.8-0.9 nm. Overall, the wide-ranging band gap tunability, high absorption coefficients, amorphous structures, surface smoothness, and low synthesis temperatures of a-ZAON films position them as promising materials for use in DUV optoelectronic devices and power devices fabricated using large-scale glass and flexible substrates.

     Carbon dioxide reduction is one of the key technologies for achieving a sustainable society. In this study, plasma catalysis were used to hydrogenate carbon dioxide to produce methane. Plasma catalysis have attracted attention in recent years as a technology promoting a reaction at lower temperatures by various synergistic effects between plasma and catalysts. In this study, molecular sieve with a pore diameter of 3 Å was used as a catalyst and its role was investigated. The results showed that: 1. molecular and atomic adsorption functions of molecular sieves are useful to inhibit reverse reactions; 2. the influence of molecular sieves becomes stronger at higher pressures, resulting in higher methane production; 3. energetic reactive particles derived from hydrogen deactivate molecular sieves; 4. molecules adsorbed on molecular sieve can be recycled by hydrogen plasma irradiation.

    Seed treatment with non-thermal plasma has seen a tremendous increase in both direct and indirect applications recently. In this review, we examined the effects of direct plasma irradiation, plasma-activated water (PAW), plasma-activated Ringer’s lactate solution, and plasma-treated soil on seeds, resulting in positive, negative, and neutral changes. Furthermore, we will compare the impact of pressure and feed gases on seed germination and seedling growth. Addition-ally, we focused on the types of reactive oxygen and nitrogen species (RONS) and their concentrations produced in the gas and liquid phases, as these play a crucial role in germination percentage and seedling growth. In conclusion, we find that plasma agriculture’s success is contingent on seed morphology, the types and concentrations of reactive species, and specific plasma characteristics.

    <p>Amorphous carbon (a-C(:H)) thin films have been studied in a wide range of fields as protective films for automotive parts, hard masks for semiconductor device fabrication, and biocompatible films for medical devices due to their excellent characteristics. In particular, mechanical properties (film stress and fracture toughness) related to film delamination are important because they are related to the durability of the films, which in turn are related to film stress and adhesion strength. Recently, we have shown that the introduction of carbon nanoparticles (CNPs) between two layers of a-C:H thin films reduces film stress[1]. In this study, we evaluated other properties of the CNP-inserted sample and examined the effect of CNPs on the mechanical properties of the film toward the practical stage.</p><p>Sandwich structure films were fabricated using a capacitively coupled plasma-enhanced chemical vapor deposition (PECVD) system [1]. Ar and CH4 gases were introduced from the top at 19 sccm and 2.6 sccm, respectively. The thickness of the first and second layers was 154 nm. For the nanoindentation test, a nanoindentation tester (ENT-1100a) was employed and a Berkovich indenter was used.</p><p></p><p>The load-unloading curve by nano-indentation showed a typical curve at 5 mN, and a step in the curve occurred at over 8 mN, and SEM images of the indentation showed that the membrane peeled off in a circular shape when the step occurred. EDS analysis of the peel scar revealed that the peel occurred at the interface between the first and second layers. In addition, the fracture toughness of the film was determined from the SEM images of the delamination traces and the load-unloading curve at the time of step generation, and it decreased with increasing Cp in the region where the film stress was constant for the CNP coverage. These results suggest that CNP coverage has a negative correlation with fracture toughness and that there is an optimum value for improving mechanical properties. Other properties will be discussed in detail in the presentation.</p><p></p><p>[1] S.H. Hwang et al., Jpn. J. Appl. Phys. 59 100906, (2020).</p>

    大気圧プラズマは種子の発芽、またその後の成長を誘導できる革新的技術である。この機構解明には、種子内へのプラズマ起因化学種導入量の定量的評価が欠かせないが、プラズマ照射された種子から化学種を実測した報告例はない。そこで本研究では、種子内へのプラズマ起因化学種導入の実験的証拠を世界へ提供するとともに、種子内化学種導入量の微量定量測定法を創成する。本研究は、プラズマ起因化学種量導入量を基にした植物分子生理学的検討から機序解明を行う学術的貢献に加え、世界の食糧安定供給に資すると期待できる。

    In this study, we aimed to clarify "what is the optimum physiological state of seeds for plasma irradiation". We found that the sensitivity of seeds to plasma irradiation changes depending on seed aging and seed coat color. The effect of plasma irradiation changes depending on the state of seeds even under the same irradiation conditions. The study also revealed that plasma irradiation can alter DNA modifications in seeds. The response to plasma irradiation differs depending on the dormancy state of seeds. For our developed scalable dielectric barrier discharge plasma, its growth-promoting effect was greater when seeds were in a deeper dormancy state.
