Abstract
BACKGROUND Potatoes are a crucial vegetable crop in Egypt in terms of production and consumption. However, the potato industry suffers significant annual losses due to brown rot disease. This study aimed to suppress Ralstonia solanacearum (R. solanacearum), the causative agent of brown rot disease in potatoes, using efficient and economical medications such as CuO and MgO metal oxide nanoparticles, both in vitro and in vivo, to reduce the risk of pesticide residues. RESULTS CuO and MgO metal oxide nanoparticles were synthesized via a simple chemical process. The average particle size, morphology, and structure of the nanoparticles were characterized using UV-visible spectroscopy, transmission electron microscopy (TEM), zeta potential analysis, X-ray diffraction (XRD), and Fourier transform infrared (FTIR) spectroscopy. The growth of R. solanacearum was strongly inhibited by CuO and MgO NPs at a concentration of 3 mg/mL, resulting in zones of inhibition (ZOI) of 19.3 mm and 17 mm, respectively. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of CuO-NPs and MgO-NPs were 0.5, 0.6, and 0.6, 0.75 mg/mL, respectively. When applied in vivo through seed dressing and tuber soaking at their respective MIC concentrations, CuO-NPs and MgO-NPs significantly reduced the incidence of brown rot disease to 71.2% and 69.4%, respectively, compared to 43.0% and 39.5% in bulk CuSO4 and bulk MgSO4 treatments, respectively. Furthermore, CuO-NPs and MgO-NPs significantly increased the yield, total chlorophyll content, and enzyme efficiency of potato plants compared with the infected control plants. TEM revealed that the bacterial cytomembrane was severely damaged by nanomechanical forces after interaction with CuO-NPs and MgO-NPs, as evidenced by lipid peroxidation and ultrastructural investigations. CONCLUSION The results of this study suggest that CuO-NPs and MgO-NPs can be used as intelligent agents to manage plant pathogens in agriculture. The use of metal oxide nanoparticles could provide a risk-free alternative for treating plant diseases, which are currently one of the biggest challenges faced by the potato industry in Egypt. The significant increase in yield, photosynthetic pigments, enzymatic activity, and total phenol-promoted resistance to R. solanacearum in potato plants treated with CuO-NPs and MgO-NPs compared to infected control plants highlights the potential benefits for the potato industry in Egypt. Further investigations are needed to explore using metal oxide nanoparticles for treating other plant diseases.

Abstract
Low-dimensional sulfur nanomaterials featuring with 0D sulfur nanoparticles (SNPs), sulfur nanodots (SNDs) and sulfur quantum dots (SQDs), 1D sulfur nanorods (SNRs), and 2D sulfur nanosheets (SNSs) have emerged as an environmentally friendly, biocompatible class of metal-free nanomaterials, sparking extensive interest in a wide range application. In this review, various synthetic methods, precise characterization, creative formation mechanism, delicate functionalization, and versatile applications of low dimensional sulfur nanomaterials over the last decades are systematically summarized. Initially, it is striven to summarize the progress of low dimensional sulfur nanomaterials from versatile precursors by using different synthetic approaches and various characterization. Then, a multi-faceted proposed formation mechanism with emphasis on how these different precursors produce corresponding SNPs, SNDs, SQDs, SNRs, and SNSs is highlighted. Besides, it is essential to fine-tune the surface functional groups of low dimensional sulfur nanomaterials to form new complex nanomaterials. Finally, these sulfur nanomaterials are being investigated in bio-sensing, bio-imaging, lithium-sulfur batteries, antibacterial activities, plant growth along with future perspective and challenges in emerging fields. The purpose of this review is to tailor low dimensional nanomaterials through accurately selecting precursors or synthetic approach and provide a foundation for the formation of versatile sulfur nanostructure.

Abstract
Elemental sulfur is a common fungicide, but its inhibition mechanism is unclear. Here, we investigated the effects of elemental sulfur on the single-celled fungus Saccharomyces cerevisiae and showed that the inhibition was due to its function as a strong oxidant. It rapidly entered S. cerevisiae. Inside the cytoplasm, it reacted with glutathione to generate glutathione persulfide that then reacted with another glutathione to produce H2S and glutathione disulfide. H2S reversibly inhibited the oxygen consumption by the mitochondrial electron transport chain, and the accumulation of glutathione disulfide caused disulfide stress and increased reactive oxygen species in S. cerevisiae. Elemental sulfur inhibited the growth of S. cerevisiae; however, it did not kill the yeast for up to 2 h exposure. The combined action of elemental sulfur and hosts’ immune responses may lead to the demise of fungal pathogens.

Abstract
Elemental sulfur and sulfite have been used to inhibit the growth of yeasts, but thiosulfate has not been reported to be toxic to yeasts. We observed that thiosulfate was more inhibitory than sulfite to Saccharomyces cerevisiae growing in a common yeast medium. At pH < 4, thiosulfate was a source of elemental sulfur and sulfurous acid, and both were highly toxic to the yeast. At pH 6, thiosulfate directly inhibited the electron transport chain in yeast mitochondria, leading to reductions in oxygen consumption, mitochondrial membrane potential and cellular ATP. Although thiosulfate was converted to sulfite and H2S by the mitochondrial rhodanese Rdl1, its toxicity was not due to H2S as the rdl1-deletion mutant that produced significantly less H2S was more sensitive to thiosulfate than the wild type. Evidence suggests that thiosulfate inhibits cytochrome c oxidase of the electron transport chain in yeast mitochondria. Thus, thiosulfate is a potential agent against yeasts.

Abstract
Over decades, sulfur has been employed for treatment of many dermatological diseases, several skin and soft tissue, and Staphylococcus infections. Because of its abuse, resistant bacterial strains have emerged. Nanotechnology has presented a new horizon to overcome abundant problems including drug resistance. Nano-sized sulfur has proven to retain bactericidal activity. Consequently, the specific aims of this study are exclusively directed to produce various sulfur nanoparticles formulations with control of particle size and morphology and investigate the antibacterial activity response specifically classified by the category of responses of different formulations, for the treatment of acne vulgaris resistant to conventional antibiotics. In this study, we produced uncoated sulfur nanoparticles (SNPs), sulfur nano-composite with chitosan (CS-SNPs), and sulfur nanoparticles coated with polyethylene glycol (PEG-SNPs) and evaluate their bactericidal impact against Staphylococcus aureus and Staphylococcus epidermidis isolated from 173 patients clinically diagnosed acne vulgaris. Accompanied with molecular investigations of ermB and mecA resistance genes distribution among the isolates. Sulfur nanoparticles were synthesized using acid precipitation method and were characterized by scanning electron microscope (SEM), transmission electron microscopy (TEM), energy dispersed x-ray spectroscopy (EDX), and Fourier transform infrared spectroscopy (FTIR). Moreover, agar diffusion and broth micro-dilution methods were applied to determine their antibacterial activity and their minimum inhibitory concentration. PCR analysis for virulence factors detection. Results: TEM analysis showed particle size of SNPs (11.7 nm), PEG-SNPs (27 nm) and CS-SNPs (33 nm). Significant antibacterial activity from nanoparticles formulations in 100% dimethyl sulfoxide (DMSO) with inhibition zone 30 mm and MIC at 5.5 µg/mL. Furthermore, the prevalence of mecA gene was the most abundant among the isolates while ermB gene was infrequent. Conclusions: sulfur nanoparticles preparations are an effective treatment for most Staphylococcus bacteria causing acne vulgaris harboring multi-drug resistance virulence factors.

Abstract
INTRODUCTION The alarming rate of infections caused by various pathogens and development of their resistance towards a large number of antimicrobial agents has generated an essential need to search for novel and effective antimicrobial agents. Metal nanoparticles such as silver have been widely used and accepted as strong antimicrobial agents, but considering the cost effectiveness and significant bioactivities, researchers are looking to utilize sulfur nanoparticles as an effective alternative to silver nanoparticles. AREAS COVERED This review has been focused on different approaches for the synthesis of sulfur nanoparticles, their broad spectrum bioactivities and possible mechanisms involved in their bioactivities. Expert commentary: Sulfur nanoparticles are reported to possess broad spectrum antimicrobial activity, and hence can be used to treat microbial infections and potentially tackle the problem of antibiotic resistance. Thus, in the future, sulfur nanoparticles can be used as an effective, non-toxic and economically viable alternative to other precious metal nanoparticles.

Abstract
BACKGROUND Elemental sulfur (S) persists in natural aquatic environment in a variety of forms with different size distributions from dissolved to particulate. Determination of S speciation mainly consists of the application of chromatographic and electrochemical techniques while its size determination is limited only to the application of microscopic and light scattering techniques. S biological and geochemical importance together with recent increases of S industrial applications requires the development of different analytical tools for S sizing and quantification. In recent years the use of electrochemical measurements as a direct, fast, and inexpensive technique for the different nanoparticles (NPs) characterization (Ag, Au, Pt) is increasing. In this work, electrochemical i.e. chronoamperometric measurements at the Hg electrode are performed for determination of the size distribution of the S NPs. RESULTS S NPs were synthesized in aqueous medium by sodium polysulphide acidic hydrolysis. Chronoamperometric measurements reveal the polydisperse nature of the formed suspension of S NPs. The electrochemical results were compared with dynamic light scattering measurements parallel run in the same S NPs suspensions. The two methods show fairly good agreement, both suggesting a log-normal size distribution of the S NPs sizes characterized by similar parameters. CONCLUSIONS The preliminary results highlight the amperometric measurements as a promising tool for the size determination of the S NPs in the water environment.
