“…Compared to the Se form in leaves, the proportion of organic Se species (SeCys and SeMet) increased in the roots of flue-cured tobacco, while Se(VI) was only detected at 22.2 mg kg -1 Se. The similar results showed that the major Se species were SeMet in Solanum tuberosum L. [35], SeCys 2 in Cardamine violifolia [36] and SeCys 2 and SeMet in Cordyceps militaris [37]. In addition, some unidentified peaks were observed in the chromatograms of the roots of flue-cured tobacco (Figure 4), and the unidentified peaks were also observed at 545 s in C. militaris [37].…”

Anion-exchange chromatography (Hamilton, PRP-X100) with hydride-generation atomic fluorescence spectrometry (HG-AFS) is commonly used for selenium (Se) speciation analysis in environmental and biological samples. However, retentions of Se species are often different with different mobile phases. To address it, this study systematically investigated mobile phases based on ammonium salts to obtain good resolution of Se species. Various mobile phases, including NH 4 H 2 PO 4 , NH 4 Ac, NH 4 NO 3 and (NH 4 ) 2 HPO 4 , were tested. The best result was obtained with a mobile phase containing 60 mmol L −1 (NH 4 ) 2 HPO 4 at pH 6.0, where the separation of Se species, including selenite [Se(IV)], selenate [Se(VI)], selenocystine (SeCys) and selenomethionine (SeMet), was achieved within 10 min with reasonable resolution. In addition, the recoveries of SeCys, Se (IV), SeMet and Se (VI) in the Se-enriched samples were 95.72 ± 1.60%, 106.89 ± 2.20%, 93.28 ± 2.82% and 91.38 ± 1.27%, respectively. Finally, the proposed method was validated for the determination of Se species in Nicotiana tabacum tissues.

“…Se content in the Se-pretreated sun ower leaves was detected mainly as the form of SeMet. SeMet is more active than selenite and can incorporate into proteins nonspeci cally through the metabolic pathways of sulfur analogues by replacing Met to the form of Se-containing proteins (Wu et al 2020;Zhang et al 2020). In plants, Secontaining proteins not only carry enzymatic functions, but also carry antioxidant activity by scavenging free radicals directly (Liu et al 2015;Zhang et al 2020).…”

Sclerotinia wilt of sunflower caused by Sclerotinia sclerotiorum is a devastating disease causing serious loss. Selenium (Se) has a benefit effect to plant in stress tolerance. In this study, sunflower leaves treated by foliar application of Se were inoculated with S. sclerotiorum. Pathogenesis on the inoculated leaves and transcript levels of plant genes involved in redox homeostasis and hormonal signaling pathways were examined. Se could be detected after the foliar application and was mainly transformed to selenomethionine in sunflower. Consequently, Se pretreatment delayed the necrosis development caused by S. sclerotiorum and alleviated the adverse effects derived from pathogen infection by differentially balancing the regulation of enzymes involved in the redox homeostasis. Specially, the cat expression increased to alleviate its downregulation responded to pathogen infection at the earlier infection stage (12 hour post inoculation, hpi) while the pod, gpx, apx, and nox expressions decreased to alleviate their responsive upregulation at the later infection stages (24 and 36 hpi). Se pretreatment enhanced the regulation of genes involved in hormonal signaling pathways, in which the AOC and PAL expressions increased to enhance its upregulation induced by pathogen infection for improving resistant responses at the earlier infection stage (12 hpi), as well as the AOC and PDF expressions increased at the later infection stages (24 hpi). Besides, the EIN2 expression increased to alleviate its downregulation at all of infection stages. Our results suggested that Se plays the beneficial effect on the resistant responses to S. sclerotiorum infection. This study provided a clue to improve the sustainable management of Sclerotinia wilt on sunflower by Se foliar application.

“…The power plants, which use solar energy, use two deposits. Each container deposits the thermal ESS of the sun, and the temperatures of two containers are 500 °C and 285 °C [ 138 ]. In the future, smart grids will shift towards the thermal ESS methods, where the cost is low and the temperature is high.…”

This paper reviews energy storage systems, in general, and for specific applications in low-cost micro-energy harvesting (MEH) systems, low-cost microelectronic devices, and wireless sensor networks (WSNs). With the development of electronic gadgets, low-cost microelectronic devices and WSNs, the need for an efficient, light and reliable energy storage device is increased. The current energy storage systems (ESS) have the disadvantages of self-discharging, energy density, life cycles, and cost. The ambient energy resources are the best option as an energy source, but the main challenge in harvesting energy from ambient sources is the instability of the source of energy. Due to the explosion of lithium batteries in many cases, and the pros associated with them, the design of an efficient device, which is more reliable and efficient than conventional batteries, is important. This review paper focused on the issues of the reliability and performance of electrical ESS, and, especially, discussed the technical challenges and suggested solutions for ESS (batteries, supercapacitors, and for a hybrid combination of supercapacitors and batteries) in detail. Nowadays, the main market of batteries is WSNs, but in the last decade, the world’s attention has turned toward supercapacitors as a good alternative of batteries. The main advantages of supercapacitors are their light weight, volume, greater life cycle, turbo charging/discharging, high energy density and power density, low cost, easy maintenance, and no pollution. This study reviews supercapacitors as a better alternative of batteries in low-cost electronic devices, WSNs, and MEH systems.
