“…In the spectrum of SiO 2 ‐HMDS, the broad peak at 2θ = 23° represents the amorphous structure of this nanofiller. [ 42–44 ] In work done by Debnath et al, [ 43 ] a similar XRD pattern was observed for the HMDS‐treated SiO 2 nanoparticles. It is also reported that the amorphous structure of SiO 2 remains intact after surface modification [ 42,43 ] because only a thin functional layer covers its surface.…”

Preparation and hydrophobicity modification of poly(vinylidene fluoride‐co‐hexafluoropropylene) membranes for pervaporation separation of volatile organic compound from water

et al. 2021

In this study, novel nanocomposite membranes were fabricated for the removal of isopropyl benzene, a volatile organic compound (VOC), from water via pervaporation (PV). The membranes were made of poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) copolymer. In order to improve the hydrophobic properties of the membranes, hydrophobic silica nanoparticles that had been surface modified by hexamethyldisilazane were used as the nanofiller in the PV membranes, for the first time. Incorporating hydrophobic silica nanoparticles into PVDF-HFP and increasing its concentration up to 9 wt% enhanced membrane hydrophobicity. Evaluation of membrane performance in VOC separation from water showed that the membrane containing 9 wt% of silica had the highest VOC separation factor, so that the values of total flux, separation factor, and PV separation index (PSI) were 3.77 g/m 2 /h; 42,483.81; and 158,788.50 g/m 2 /h for this membrane, respectively. The separation factor and PSI value of the mentioned membrane were almost 204 and 5 times higher than that of the neat PVDF-HFP membrane.

“…Magda and Hussein (2016) compared the effects of SiO 2 gel and nano-SiO 2 gel against the tomato pest Tuta absoluta (T. absoluta) and found that the infestation percentage significantly decreased by 89.7 % with nano-SiO 2 gel and by 70.6 % with SiO 2 gel. The same trends were also observed against larvae of cabbage moth (Plutella xylostella L.) with 85 % mortality in 72 h (Shoaib et al 2018).…”

Environmental contextNano-enabled agriculture holds the promise of enhancing crop production while reducing the environmental impacts of agrochemicals. We review recent developments in the use of nano-fertilisers, nano-additives, nano-pesticides, nano-sensors, nano-cleansers and nano-delivery systems in agriculture. The review highlights the need for systematic studies on nanotoxicity and the development of cost-effective and eco-friendly nanomaterials for future applications. AbstractTo keep pace with the ever-increasing demand of world population (nearly 9.8 billion), worldwide food production will need to increase by 50% by 2050. Nanotechnology innovations show great promise for combating this challenge by delivering a more sustainable, efficient and resilient agricultural system, while promoting food security. Further exploration of nanotechnology applications in agriculture is necessary to realise its potential in manufacturing innovative agrochemicals and novel delivery platforms to enhance crop production and quality. Here, we review the fundamentals of nanotechnology and focus on its potential in agricultural applications. Progress has been made in the development of nano-fertilisers, nano-additives, nano-pesticides, nano-herbicides, nano-bactericides, nano-cleansers and nano-sensors to improve agrochemical efficiency, reduce runoff, enhance plant growth, and diagnose plant nutrition deficiencies and diseases. In addition, nano-delivery systems have been designed to deliver effective components to targeted sites within a plant to provide potential solutions to some devastating crop diseases which cannot be effectively managed with conventional methods. However, nano-enabled agriculture is still in its infancy and its applications are mostly theoretical. Therefore, more research is needed to develop biodegradable, cost-effective and safe nanomaterials for future application. Moreover, systematic studies are crucial to safeguard our food production system, while making efforts to raise public awareness of nanotechnology.

“…The entomotoxicity of silica‐based nanoparticles per se has been proven against different lepidopteran pests [ 23,24,25 ] including S. littoralis . [ 26,27 ] Similarly, the insecticidal activity of citrus essential oils has been demonstrated in several lepidopterans including the cotton leafworm.…”

An ultralow amount of sub‐micron spherical SiO2 particles encapsulating 7 wt% crude orange oil (SiliOrange) suspended in water shows surprisingly high insecticidal activity against the cotton leafworm Spodoptera littoralis, and significantly reduces the progeny of cotton aphid Aphis gossypii under laboratory testing conditions. Considering the ease of reproducible preparation of the material and the biocompatible nature of both silica and orange essential oil, these results may open the route to sustainable pest control using new biopesticide water‐based formulations based on sol–gel microencapsulated orange oil.
