Green protocols for the synthesis of nanoparticles have gained significant attention due to their environmental friendliness, ease, and cost-effectiveness. The present study focused on the synthesis of magnesium oxide nanoparticles (MgO-NPs) using an aqueous leaves extract of Syzygium cumini plant, and the antimicrobial potential of the synthesized NPs. Methods: The synthesis of MgO-NPs was achieved by mixing a solution of magnesium nitrate (Mg (NO3)2 with an aqueous extract obtained from S. cumini leaves to reduce the Mg+ ions. These NPs were characterized by X-ray diffraction (XRD), Fourier-Transform Infrared (FTIR) Spectroscopy analysis, Scanning electron microscopy (SEM), and Energy-dispersive X-ray (EDX) analysis. Results: The transformation in color of the solution from yellow to deep brown along with the UV absorption peak at 294 nm showed the effective synthesis of MgO-NPs. SEM and XRD data revealed cubic-shaped NPs with an average size of 23.73 nm. EDX analysis confirmed the presence of magnesium and oxygen in the sample at 31.85% and 35.11% weight percentages, respectively. The antibacterial evaluation demonstrated effectiveness against the gram-negative strains Citrobacter koseri and Pseudomonas aeruginosa, with inhibition zones of 28.1 ± 1.25 mm and 27.8 ± 1.25 mm, respectively. MgO-NPs also showed antileishmanial potential against Leishmania tropica promastigotes (68.41 ± 0.05% inhibition at 1000µg/ml). Furthermore, the NPs exhibited antioxidant properties (75.12 ± 4.29% at 1 mg/ml) as determined by the DPPH radical scavenging assay. Conclusions: MgO-NPs synthesized using S. cumini plant leaves extract hold promises as agents for antibacterial, antileishmanial, and antioxidant applications.

Green fabrication of titanium dioxide nanoparticles via Syzygium cumini leaves extract: characterizations, photocatalytic activity and nematicidal evaluation

ABSTRACT The most significant plant parasitic nematode in terms of economic impact is root-knot nematode (Meloidogyne incognita), which severely harms essential crops used for agriculture. This study investigated green fabrication of titanium dioxide nanoparticles (TiO2 NPs) utilizing Syzygium cumini (SC) leaf extract and evaluated its nematotoxic activity against M. incognita in vitro and in pots. During experiments, second-stage juveniles (J2s) and egg masses of M. incognita were treated with different concentrations (125, 250, 375 and 500 ppm) of SC-TiO2 NPs. After 48 h and five days of exposure, respectively, lowest J2s mortality and per cent inhibition in egg hatching was discovered at 125 ppm, and highest J2s mortality and maximum per cent inhibition in egg hatching determined at 500 ppm. The treatment of SC TiO2 NPs considerably reduced M. incognita infection and enhanced carrot plants' growth and physiological characteristics. The characterization of green synthesized SC-TiO2 NPs made by X-ray diffraction, Photoluminescence, FTIR, SEM, UV-Visible Diffuse Reflectance Spectrophotometer, TEM, and photocatalytic activity also examined. In conclusion, it can be said that SC-TiO2 NPs possess nematode-toxic potential against M. incognita and are used as substitutes for high-risk chemical nematicides without causing any phytotoxicity.

Electrochemical impedance spectroscopy analysis of dye-sensitized solar cells composed of electrospun composite photoanodes: A comparative study of natural and synthetic sensitizers

In this study, a transmission line model is applied to the electrochemical impedance spectroscopy (EIS) data of the fabricated dye-sensitized solar cells (DSSCs) to evaluate the charge transfer mechanism through the cells. Natural dye from black plum (Syzygium cumini) fruit was used as a cell sensitizer (SC-DSSC) and compared its photovoltaic and electron transport capabilities to those of a cell using a synthetic sensitizer (N719-DSSC). TiO2/ZnO electrospun composite nanofibers were used as the semiconductor layer of the photoanode to enhance electron transfer. The EIS analysis revealed the role of electron resistances through shant, interfaces, and electrolyte solution by measuring the electron transfer kinetic parameters of each element. Based on the results, the SC-DSSC and N719-DSSC are appropriate photovoltaic cells because their ratios of effective electron diffusion length to photoanode thickness are 12.5 and 2.8, respectively. The EIS analysis showed that the electrospun composite nanofiber coated on the photoanode reduces the semiconductor layer's electrical resistance to the cell's total resistance. The extracted natural dye also boosted electron lifetime to 3.68 ms and diffusion coefficient to 54.3×10−6 m2/s while minimizing back-electron recombination at the semiconductor-electrolyte interface. Moreover, the semiconductor-electrolyte interface resistance is over 85% of the overall resistance for both DSSCs and controls electron transport through the cells, which is due to the dye-semiconductor binding intensity. Based on the photovoltaic data, the SC-DSSC cell efficiency was lower than N719-DSSC which is attributed to its higher electron transfer rate-controlling element. Thus, enhancing dye-semiconductor interactions will decrease the rate-controlling impedance and enhance cell performance.

Modified refractance window drying of jamun pulp (Syzygium cumini) based on innovative infrared and microwave radiation techniques

The present study aimed to dry jamun pulp (Syzygium cumini) by combining infrared and microwave energy in refractance window drying. The two different sets of experiments were planned using the hybrid design. The three independent parameters considered for the infrared refractance window drying (IR-RWD) included infrared lamp power (30–70% of the 1000 W lamp), pulp layer thickness (1–3 mm), and distance between the lamp and pulp layer (3.42–6.60 cm). In microwave refractance window drying (MW-RWD), the independent variables were oven-set microwave power (150–450 W), pulp layer thickness (1–3 mm), and power density (1–2.5 W g−1). The optimum conditions in IR-RWD were 40.75% infrared lamp power, 1 mm pulp layer thickness, and 3.42 cm distance between the lamp and pulp layer, resulting in dry jamun flakes with 17.93 ± 0.32 mg GAE g−1 total phenolic content, 4.37 ± 0.13 color change, 8.90 ± 0.22 mg QE g−1 total flavonoid content, and 179.05 ± 2.17 C3G mg/100g total anthocyanin content. In the case of MW-RWD, the optimum conditions were 212.4 W oven-set microwave power, 3 mm pulp layer thickness, and 2.2 W g−1 power density, resulting in 15.68 ± 0.28 mg GAE g−1 total phenolic content, 8.47 ± 0.25 color change, 8.20 ± 0.21 mg QE g−1 total flavonoid content, and 149.72 ± 1.81 C3G mg/100g total anthocyanin content. The Page model can precisely describe the jamun pulp drying behavior of IR-RWD and MW-RWD. Also, apparent moisture diffusivity was estimated in both drying methods. IR-RWD was found to be a better drying method than MW-RWD in terms of drying rates and the quality parameters of the dry jamun flakes.

Green-Synthesized Sm3+-Doped ZnO Nanoparticles for Multifunctional Applications

The present study focuses on the green-mediated synthesis of pristine and Sm3+-doped ZnO nanoparticles using Syzygium cumini fruit extract. The prepared material was characterized by various characterization techniques. Photocatalytic degradation of a fast orange red (FOR) dye under UV light resulted in 88% degradation, with a minimal decrease (87.90%) observed even after five successive runs, indicating the stability and effectiveness of the catalyst. The enhancement in degradation efficiency is attributed to the incorporation of Sm3+ ions into the ZnO lattice. Utilizing the optimized Sm3+ (5 mol%)-doped ZnO nanoparticles, cyclic voltammetry (CV) and electrochemical impedance spectra (EIS) were performed on the prepared electrode, demonstrating the excellent CV properties; this enhancement is attributed to the modification of ZnO’s redox chemistry and the alteration of charge transfer kinetics at the electrode-electrolyte interface due to the addition of Sm3+ into the ZnO structure. The antibacterial activity was performed against two pathogenic strains, i.e., Escherichia coli and Streptococcus aureus. The obtained results suggest that the prepared material holds great promise for catalytic, energy storage, antibacterial, and other multifunctional applications.

Syzygium cumini (Black berry), a traditional Indian herbal plant, has been researched and found to exert cardioprotective, anti-inflammatory, and antioxidant activities, which have been credited due to the presence of polyphenols, flavonoids, and tannins. In the current research, we investigated the cardioprotective potential of Syzygium cumini against Doxorubicin-induced cardiotoxicity (DIC) in H9C2 cardiomyocytes. Methanolic seed extract preparation of Syzygium cumini was performed using the Soxhlet apparatus. Cell viability and cell death assays were performed to determine the cardiotoxic doses of Doxorubicin. Furthermore, the cardioprotective potential of Syzygium cumini extract against DIC was studied. Morphological and nuclear alterations in H9C2 cells were studied by microscopic assays using Giemsa, Haematoxylin-Eosin stain, and PI. The intracellular stress level and ROS production were studied using DCFH-DA followed by mitochondrial integrity analysis using fluorescent microscopic methods. In the results, we investigated that Dox exerted a dose and time-dependent cardiotoxicity on H9C2 cardiomyocytes. Moreover, we observed that morphological and nuclear alterations caused by doxorubicin in dose-dependent manner were prevented by supplementing with Syzygium cumini polyphenols and it attenuated the oxidative stress in H9C2 cardiomyocytes effectively. Conclusively, Syzygium cumini possesses cardioprotective potential in H9C2 cardiomyocytes in dox-induced cardiotoxicity.
