“…Previously, we reported that a multi-gas plasma jet was able to cause surface hydrophilization of polyimide films [ 9 ]. It was also reported that anesthetic gas and toxic chemicals could be decomposed using atmospheric-pressure plasmas [ 10 , 11 ]. Regarding the effects on organisms, non-thermal atmospheric-pressure plasmas inactivated bacteria and biomolecules [ 12 – 16 ].…”

Protein introduction into cells is more difficult in plants than in mammalian cells, although it was reported that protein introduction was successful in shoot apical meristem and leaves only together with a cell-penetrating peptide. In this study, we tried to introduce superfolder green fluorescent protein (sGFP)-fused to adenylate cyclase as a reporter protein without a cell-penetrating peptide into the cells of tobacco leaves by treatment with atmospheric non-thermal plasmas. For this purpose, CO2 or N2 plasma was generated using a multi-gas plasma jet. Confocal microscopy indicated that sGFP signals were observed inside of leaf cells after treatment with CO2 or N2 plasma without substantial damage. In addition, the amount of cyclic adenosine monophosphate (cAMP) formed by the catalytic enzyme adenylate cyclase, which requires cellular calmodulin for its activity, was significantly increased in leaves treated with CO2 or N2 plasma, also indicating the introduction of sGFP-fused adenylate cyclase into the cells. These results suggested that treatment with CO2 or N2 plasma could be a useful technique for protein introduction into plant tissues.

“…Nevertheless, all these technologies may have their own limitations like formation of secondary pollutants like NO x , poisoning of the catalyst and relatively high process cost. Some of the recent developments for direct decomposition of N 2 O in this direction are perovskite hollow fibber membranes,12 photocatalytic oxidation,13, 14 and electrical discharges 15–21. Among these new methods, attention has been focused in recent years to non‐thermal plasma (NTP) processing which may provide a unique advantage of direct decomposition even under highly dilute conditions.…”

Direct decomposition of nitrous oxide (N2O) was studied in a non‐thermal plasma (NTP) dielectric barrier discharge (DBD) reactor operated under ambient conditions. Influence of various parameters like discharge gap, input power, residence time, and N2O concentration were studied to achieve high conversions. The conversion decreased with increasing flow rate and N2O concentration. Typical results indicated that N2O decomposition may be efficient at high residence time and low concentrations. The degree of N2O decomposition varied between 30 and 100% with the power variation between 0.5 and 2.7 W. Interesting observation is that packing the discharge volume with dielectric materials (ceramic, glass, and Al2O3 beads) improved the conversion. Under the same experimental conditions, the effect of the dielectric materials followed the order: ceramic beads > glass beads > Al2O3 beads > no packing. It was concluded that packed bed plasma reactor may be an efficient way for the reduction of N2O emissions.

“…ICP was generated using a Matching Box (Matching Box, Plasma Concept Tokyo Inc., Tokyo, Japan). [17][18][19] The RF generator power supply was maintained at 1200 W, the plasma gas-flow rate was 15 L/min, and the auxiliary gas-flow rate was 1 L/min. A multichannel spectrometer (HR 4000, Ocean Optics Inc., FL) was used for recording the emission spectra.…”

With a view to enhance the sensitivity of analytical instruments used in the measurement of trace elements contained in a single cell, we have now equipped the previously reported micro-droplet injection system (M-DIS) with a desolvation system. This modified M-DIS was coupled to inductively coupled plasma atomic emission spectroscopy (ICP-AES) and evaluated for its ability to measure trace elements. A flow rate of 100 mL/min for the additional gas and a measurement point -7.5 mm above the load coil (ALC) have been determined to be the optimal parameters for recording the emission intensity of the Ca(II) spectral lines. To evaluate the influence of the desolvation system, we recorded the emission intensities of the Ca(I), Ca(II), and H-β spectral lines with and without inclusion of the desolvation system. The emission intensity of the H-β spectral line reduces and the magnitude of the Ca(II)/Ca(I) emission intensity ratio increases four-fold with inclusion of the desolvation system. Finally, the elements Ca, Mg, and Fe present in a single cell of Pseudococcomyxa simplex are simultaneously determined by coupling the M-DIS equipped with the desolvation system to ICP-AES.
