“…The corresponding voltage and current were 40 kV and 30 mA, respectively. The average size of SiO 2 -NPs synthesized by fungal metabolites was calculated using the Debye–Scherrer Equation (1) [ 42 ]: D = (Kλ/β Cos θ) where D is the mean particle size, where K is the Scherrer constant, λ is wave length of the X-ray beam used (1.54, 184 Å), β is the Full width at half maximum (FWHM) of the peak and θ is the Bragg angle, respectively. The particle size distribution of the SiO 2 -NPs was evaluated using dynamic light scattering (DLS) measurements, which gives the hydrodynamic diameter of particles [ 43 ].…”

The threats to the life and production of crops are exacerbated by climate change and the misuse of chemical pesticides. This study was designed to evaluate the effectiveness of biosynthesized silica nanoparticles (SiO2-NPs) as an alternative to pesticides against early blight disease of eggplant. Antifungal activity, disease index, photosynthetic pigments, osmolytes, oxidative stress, antioxidant enzymes activities were tested for potential tolerance of eggplant infected with Alternaria solani. Silica nanoparticles were successfully biosynthesized using Aspergillus niger through green and ecofriendly method. Results revealed that SiO2-NPs exhibited promising antifungal activity against A. solani where MIC was 62.5 µg/mL, and inhibition growth at concentration 1000 µg/mL recorded 87.8%. The disease Index (DI) as a result of infection with A. solani reached 82.5%, and as a result, a severe decrease in stem and root length and number of leaves occurred, which led to a sharp decrease in the photosynthetic pigments. However, contents of free proline, total phenol and antioxidant enzymes activity were increased in infected plants. On the other hand, the treatment with SiO2-NPs 100 ppm led to a great reduction in the disease Index (DI) by 25% and a high protection rate by 69.69%. A clear improvement in growth characteristics and a high content of chlorophyll and total carotenoids was also observed in the plants as a result of treatment with silica nanoparticles in (healthy and infected) plants. Interestingly, the noticeable rise in the content of infected and healthy plants of proline and phenols and an increase in the activity of super oxide dismutase (SOD) and polyphenol oxidase (PPO). It could be suggested that foliar application of SiO2-NPs especially 100 ppm could be commercially used as antifungal and strong inducer of plant physiological immunity against early blight disease.

“…Silica from sugarcane bagasse is used for its antibacterial activities [237], photocatalysis ability against dyes [238,239] and heavy metals [152], used in agriculture [240], and has applications in hydrophobic coatings [241], insect control [242], membranes for wastewater purification [243,244], and fillers in polymeric composites [232]. Hikmah et al (2021) developed Fe 3+ -doped SiO 2 /TiO 2 composites using silica from sugarcane bagasse ash as an adsorption site to TiO 2 particles and promoted 98.18% degradation of Congo red dye through photocatalysis [238].…”

Sugarcane has primarily been used for sugar and ethanol production. It creates large quantities of residual lignocellulosic biomass such as sugarcane bagasse, leaves, tops, and vinasse. Biomass is a sustainable prospect for biorefineries aiming to optimize production processes. We detail recent research developments in recycling sugarcane, including energy generation and pyrolysis to obtain biofuels, for example. To produce biochar, the energy cost of operating at high temperatures and large-scale production remain as obstacles. The energy generation prospects can be enhanced by pellet production; however, it requires an improvement in quality control for long-term storage or long-distance transportation. In civil construction, the materials still need to prove their long-term efficiency and reliability. Related to adsorbent materials, the use of sugarcane bagasse has the advantage of being low-cost and environmentally friendly. Nevertheless, the extraction, functionalization, and modification of cellulose fibers, to improve their adsorption properties or even mode of operation, still challenges. The synthesis of nanostructures is still lacking high yields and the ability to scale up. Finally, controlling dispersion and orientation and avoiding fiber agglomeration could improve the mechanical response of composites using sugarcane bagasse. The different possibilities for using sugarcane and its residues reinforce the importance of this material for the industry and the global economy. Thus, the present work addresses current challenges and perspectives of different industrial processes involving sugarcane aiming to support future research on waste-derived subjects.

“…SiO 2 NPs are increasingly prepared from plants and agriculture byproducts. Researchers reported that SiO 2 NPs can effectively control Spodoptera littoralis, a polyphagous plant pest [11,15,27]. In a recent study of our lab (To be published), SiO 2 NPs prepared from amorphous silica powder derived from olive stones and corncobs were effectively impacted in larval mortality, pupal weight, larval and pupal development times of P. operculella.…”

Morphological and microstructural properties of silica (SiO 2 ) are essential factors that need to be considered during the experimental applications. In this report, SiO 2 nanoparticles (NPs) have been prepared at different concentrations from SiO 2 powder derived from olive stones and corncobs by an alkali leaching extraction method. Thermal treatment has been used to modify the morphological and microstructural properties of the extracted SiO 2 . X-ray diffraction (XRD) shows that the extracted amorphous SiO 2 has been transformed into a crystalline phase after the thermal treatment. Nitrogen adsorption-desorption measurements revealed signi cant reduction in both the speci c surface area (SABET) and the total pores volume (Vtotal) of the derived SiO 2 samples after the thermal treatment. The acquired thermal treatment properties of SiO 2 found to have high impacts on the in uence of the SiO 2 NPs on the survival and development of larvae and pupae of P. opercullela. SiO 2 NPs prepared from the crystalline silica samples exhibited less e ciency on suppressing potato tuber moth comparing to SiO 2 NPs of the amorphous silica powders. Varied effects on biological parameters including larvae mortality, pupae weight, larval and pupal development time, fecundity and fertility are also linked to the SiO 2 NPs source type and showed concentration depending manner effects. SiO 2 NPs are conditionally effective as an alternative pesticide against P. opercullela, based on their sources, mesoporous structures and concentrations.
