“…6 TEM image (Figure 3a) shows spherical SNPs with a tendency to agglomerate with an average diameter of 28 nm and a narrow size distribution (standard deviation of ±4.5 nm, see histogram in Figure 3b). The diameter agrees with other research which used the same method of SNPs synthesis by chemical precipitation from sodium thiosulfate as a sulfur source [28,29,30].…”

“…Figure 1 shows the UV-visible spectrum of the synthesized SNPs; a maximum absorption peak was observed at 253 nm indicating their successful formation. SNPs have been reported to show maximum absorption peak in the range of 250 to 400 nm [28,29,30]. EDS analysis (Figure 2) shows the presence of sulfur at a mass percent of 28%.…”

“…EDS analysis (Figure 2) shows the presence of sulfur at a mass percent of 28%. Furthermore, other elements (Na, Cl, and O) corresponding to the by-products of the reduction reaction (Equation 1) of sodium thiosulphate to obtain sulfur were found [19,28,31]. The presence of the element carbon is due to the substrate used in the EDS analysis [32,33].…”

The purpose of this research was to synthesize nanocomposites formed by sulfur nanoparticles, coated with eucalyptus and rosemary essential oil. To determinate the insecticidal effect in the control of nymphs of paratrioza (Bactericera cockerelli Sulc) in potato crops. A solution of thiosulfate was reduced to zero valent sulfur, the sulfur nanoparticles were coated with eucalyptus and rosemary essential oil at three concentrations: 0.25%, 0.5% and 0.75%. The samples were characterized by UV-visible spectroscopy, energy dispersive spectroscopy, transmission electron microscopy and scanning electron microscopy. Insecticidal efficacy was evaluated at 24, 48 and 72 hours after application. Furthermore, efficacy was compared versus the commercial insecticide thiamethoxam 0.25% and a control. The results show that eucalyptus nanocomposites at concentrations: 0.25%, 0.5% and 0.75% and rosemary nanocomposites at concentration of 0.5%, have an insecticidal efficacy of 100% for the control of insect nymphs 24 hours after application. While the insecticidal efficacy of rosemary nanocomposites at concentrations of 0.25% and 0.75% increases over time, reaching 100% at 24 and 72 hours respectively. The synthesized nanocomposites are more effective in controlling nymphs of paratrioza than the commercial insecticide thiamethoxam. Could be used for the development of new insecticides.

“…This absorption due to the n→σ* transition of nonbonding electrons is a confirmation of SNP formation [28,29]. Furthermore, it is well known that α-sulfur shows a maximum absorption peak in the range of 250 to 400 nm [30,31]. Other researchers found clear light absorption peaks of SNPs at 240, 260 and 280 nm [32,33].…”

The purpose of this research was to synthesize nanocomposites consisting of sulfur nanoparticles coated with eucalyptus and rosemary essential oils to determine the insecticidal effect in the control of nymphs of paratrioza (Bactericera cockerelli (Sulc) (Hemiptera: Triozidae)) in potato crops. A solution of thiosulfate was reduced to elemental sulfur, and the sulfur nanoparticles were coated with eucalyptus and rosemary essential oils with the three concentrations of 0.25%, 0.5%, and 0.75%. The samples were characterized by UV–visible spectroscopy, energy-dispersive X-ray spectroscopy, transmission electron microscopy, and scanning electron microscopy. The insecticidal efficacy of the nanocomposites was evaluated in the entomology laboratory 24, 48, and 72 h after application. Furthermore, efficacy was compared to the commercial insecticide thiamethoxam (0.25%) and a control. The results show that eucalyptus nanocomposites with oil concentrations of 0.25%, 0.5%, and 0.75% and rosemary nanocomposites with an oil concentration of 0.5% have an insecticidal efficacy of 100% for the control of insect nymphs 24 h after application. The insecticidal efficacy of rosemary nanocomposites with oil concentrations of 0.25% and 0.75% increases over time and reaches 100% at 24 and 72 h, respectively. The synthesized nanocomposites are more effective in controlling nymphs of paratrioza than the commercial insecticide thiamethoxam; thus, they could be used for the development of new insecticides.

“…As a result, GS2 demonstrated superior charge/discharge capabilities with uniform electrochemical access to the coated sulfur material on graphene oxide. Due considerations, such as the coarsening effect of sulfur leading to larger particles [58], the interactions of sulfur-containing intermediates with the media [59][60][61][62] and interactions with the scaffold should be considered, allowing us to design a better scaffold for the cathode in lithium-sulfur batteries.…”

Lithium-sulfur (Li-S) batteries are postulated as next-generation electrochemical energy storage devices due to their increased storage capabilities. However, challenges persist from the polysulfide-shuttle effect at the cathode. Soluble sulfur-based species in the cathode cross over to the lithium anode through the separator leading to fading capacity with cycling. This has spurred continuous effort by the scientific community to develop novel cathodes where sulfur species can affix better. A conductive nanostructured graphene network is a suitable candidate that can serve as a scaffold for holding sulfur nanoparticles. Here, a one-pot synthesis of chemically reduced graphene oxide networks prepared from easily accessible graphene oxide is demonstrated. The solution-based method simply allows for impregnation of the graphene oxide network with sulfur nanoparticles through a careful manipulation of pH of the chemical environment. Two routes were chosen for the precipitation of such sulfur nanoparticles: firstly, the dissolution of sulfur in sodium hydroxide into polysulfides followed by acidification and secondly, the acidification of sodium thiosulfate from alkaline media into sulfur nanoparticles. Both graphene oxide materials from the two routes were treated with sodium borohydride to achieve conductive graphene. The second route, with the sulfur nanoparticles derived from the acidification of sodium thiosulfate with chemically reduced graphene oxide, demonstrated favorable electrochemical behavior, showing promise as electrode material for Li-S batteries.
