Abstract Plasma agriculture as a novel approach started to gain more attention in the last decade. In this work, effect of plasma activated water (PAW) prepared with different sources from three types on germination and growth Cucumis melo L. was studied. The best PAW distilled seedlings observed when using surface-wave-sustained microwave discharge. artificially (ArtPAW) studied, however, it found that while ArtPAW may cause similar effects PAW, is not significant consistent. Further, tap...
Nowadays, laser-based techniques play a significant role in medicine, mainly the ophthalmology, dermatology, and surgical fields.
In this work we investigate the relationship of F line and CaF bands with varying Ca contents.
Automatic baseline subtraction significantly improves the quality of high-background spectra but might harm low-background spectra.
The improving performance of the laser-induced breakdown spectroscopy (LIBS) triggered its utilization in challenging topic soft tissue analysis. Alterations elemental content within tissues are commonly assessed and provide further insights biological research. However, laser ablation is a complex issue demands priori optimization, which not straightforward respect to typical LIBS experiment. Here, we focus on implementing an internal standard into analysis samples. We achieve this by...
The main purpose of this work is to thoroughly describe the implementation protocol laser-induced breakdown spectroscopy (LIBS) method in plant analysis. Numerous feasibility studies and recent progress instrumentation trends chemical analysis make LIBS an established bioimaging. In work, we present easy straightforward phytotoxicity case study with a focus on method. We intend demonstrate detail how manipulate plants after exposures prepare them for analyses. Moreover, aim achieve 2D maps...
Nanoparticles (NPs) applied to the surface of some solids can increase signals in inductively coupled plasma mass spectrometry (ICPMS). Drops containing 20 and/or 40 nm nanoparticles Ag Au were deposited on metallic and ceramic/glass samples, after being dried, both samples treated with NPs plain targets ablated by one pulse per spot. The laser ablation ICPMS (LA-ICPMS) enhanced for modified comparison produced at plain, untreated surface. Maps LA-ICPMS recorded several fluences show that...
Abstract In this work, we proposed a new data acquisition approach that significantly improves the repetition rates of Laser-Induced Breakdown Spectroscopy (LIBS) experiments, where high-end echelle spectrometers and intensified detectors are commonly used. The moderate recent LIBS systems caused by utilization their slow full frame ( i.e . echellogram) readout speeds with consequent necessity for echellogram-to-1D spectrum conversion (intensity vs wavelength). Therefore, investigated...
Contamination of the environment with toxic metals such as cadmium or lead is a worldwide issue. The accumulator Cannabis sativa L. has potential to be utilized in phytoremediation, which an environmentally friendly way soil decontamination. Novel non-thermal plasma-based technologies may helpful tool this process. Plasma activated water (PAW), prepared by contact gaseous plasma water, contains reactive oxygen and nitrogen species, enhance growth plants. In study, C. was grown short-term...
