“…This result of color changes was in agreement with a previous study reported by Khan et al [ 19 ]. UV-Vis spectroscopy showed a unique SPR absorption band at around 400 nm, typical in AgNPs, and indicated that the particles were dispersed without aggregation [ 20 ]. The XRD pattern of AgNPs confirms the crystallinity with a face-centered cubic (FCC) plane ((JCPDS, File No.…”

Salinity is one of the major abiotic stresses that affect the plant’s growth and development. Recently, the contribution of nanoparticles (NPs) to ameliorating salinity stresses has become the new field of interest for scientists due to their special physiochemical properties in the biological system. This study is designed to examine the effects of biosynthesized silver nanoparticles (AgNPs) spherical in shape (size range between 9 and 30 nm) on morphophysiological characteristics and the antioxidant defense system of in vitro raised Maerua oblongifolia under four levels of salt stress (0, 50, 100, and 200 mM NaCl). Our findings reveal that the application of AgNPs (0, 10, 20, and 30 mg/L) to M. oblongifolia shoots significantly alleviates the adverse effects of salt stress and ameliorates plant developmental-related parameters and defense systems. High salinity elevates the oxidative damage by over-accumulation of the levels of total soluble sugars, proline, hydrogen peroxide (H2O2), and malondialdehyde (MDA). In addition, enhancing the activity of the antioxidant enzymes, total phenolic, and flavonoid content over the control. Interestingly, the application of AgNPs to salinized plants improved the growth traits and photosynthetic pigment production and caused higher enhancement in antioxidant enzyme activities. Furthermore, mitigating the oxidative damage by lowering the accumulation of proline, soluble sugars, H2O2, MDA, and total phenolic and flavonoid contents in salt-stressed plants. In general, AgNPs augmented the growth of M. oblongifolia shoots under saline conditions through different strategies; thus, AgNPs can be used as an appropriate eco-friendly approach that enhances salinity tolerance in plants.

“…Consistent with our results, Jebril et al [51] reported the efficacy of Melia azedarach leaf extract to synthesize AgNPs at an SPR value of around 400 nm. This obtained peak (400 nm) is typical for AgNPs and demonstrates that the particles were evenly distributed without clumping together [52]. As indicated in numerous research investigations, the SPR wavelength for silver nanoparticles (AgNPs) produced through biological synthesis falls within the range of 400-450 nm.…”

In recent years, nanotechnology has shown promising potential to enhance sustainable agriculture. Besides their use as antifungal and antimicrobial agents, silver nanoparticles (AgNPs) are the most widespread nanomaterials and are found in a capacious range of agrocommercial products. This study was designed to investigate the responses of morphophysiological characteristics in barley (Hordeum vulgare L.) to biologically synthesized silver nanoparticles. Spherical shapes with 8–20 nm size AgNPs at different concentrations (0, 50, 100, 150, 200, and 250 mg/L) were applied to barley plants in a hydroponic system. Following 7 days of sowing, the growth performance, chlorophyll contents, oxidative damage, and the activity level of antioxidant enzymes were quantified in different parts of the plant. The results indicated a remarkable boost in the growth performance and chlorophyll contents of barley plants up to a concentration of 150 mg/L. Interestingly, the levels of proline, lipid peroxidation, enzymes; superoxide dismutase (SOD), catalase (CAT), (APX), and (GR) activities were enhanced significantly in response to all AgNPs treatments. In general, the application of AgNPs substantially improved the growth and related morphophysiological attributes in barley. Our results provide new insights with respect to the effects of AgNPs on barley growth and their potential applications in increasing the performance of other crop species.

“…The dye decomposition rates of methylene blue under different pressures are listed in Table 1 from which it can be observed that the rates were low. According to our previous study, 21 the concentration of reactive species generated by plasma increases with an increase in the number of electrodes. Therefore, the number of electrodes was increased to seven, including three ground electrodes and four high-voltage electrodes (Figure 3b).…”

Pulsed discharge plasma produced in a gas/liquid environment has attracted much attention because of its low energy requirement and the generation of various radical species with high reactivity. In our previous work, a slug flow system was developed to produce gas/liquid plasma under atmospheric pressure, generating continuous bubbles and stable gas–liquid interfaces. Currently, meaningful results have also been obtained in the field of plasma under high-pressure conditions. Therefore, in this study, a slug flow system using gas/liquid discharge plasma was implemented under pressurized argon. The system pressure was controlled from 0.1 (atmospheric pressure) to 0.4 MPa, and the effect of pressure on the system was investigated. This system was also applied to the decomposition of methylene blue. The chemical reactivity was studied, and the energy of the system was calculated. The results showed that as the system pressure increased, the decomposition rate of methylene blue decreased, while the concentration of the total oxidation species increased. This can be explained by a decrease in the energy available for methylene blue decomposition owing to the steady input energy and increasing energy loss.
