“…Another intriguing concept is to use nanostructures as reinforcing materials. A variety of reinforcements are used to improve the properties of matrix materials, including SiO 2, TiO 2 , CuO, Al 2 O 3 , SiC 10 boron carbide, titanium carbide, titanium diboride, silicon nitride, silicon carbide, and zirconium dioxide 11 , 12 . Nanoparticulate-reinforced materials serve as nucleation sites for solidification, resulting in enhanced durability and high strength and an improvement in both yield strength and ductility.…”

Aluminum alloys have been widely studied because of their current engineering applications. Due to their high strength and lightweight, cracking can easily initiate on their surface, deteriorating their overall functional and structural properties and causing environmental attacks. The current study highlights the significant influence of incorporating 1 wt% silica nanostructure in aluminum-10 zinc alloys. The characteristics of the composites were examined using Vickers hardness, tensile, and electrochemical testing (OCP, Tafel, and EIS) at various artificial aging temperatures (423, 443, and 463 K). Silica nanorods may achieve ultrafine grains, increase hardness by up to 13.8%, increase σUTS values by up to 79% at 443 K, and improve corrosion rate by up to 89.4%, surpassing Al-10 Zn bulk metallics. We demonstrate that silica nanorods contribute to the creation of a superior nanocomposite that not only limits failure events under loading but also resists corrosion. Our findings suggest that silica nanocomposite can produce unique features for use in a variety of automotive, construction, and aerospace applications. This improvement can be attributed mainly to the large surface area of nano-silica particles, which alters the Al matrix. Microstructural, mechanical, and electrochemical studies revealed that the effects of structure refinement were dependent on nano-silica.

The world's population is expected to increase to 10 billion humans through the 12 months 2050, which poses an extreme venture to agriculture's potential to deliver the developing demand for meals in a sustainable way at the same time as minimizing unfavourable environmental outcomes. The rising need for food worldwide has led to the widespread usage of fertilisers. The widely used chemical fertilisers can improve crop production and expansion, but they are harmful to the environment, the soil, as well as the health of people. As a result, one of the most intriguing alternatives to conventional fertilisers is nanofertilizer. These synthetic materials consist of nanoparticles that are regulated in their delivery of macro-and micronutrients to the plant rhizosphere. The necessary nutrients as well as minerals are bound together either alone or in conjunction with nano-sized adsorbents in nano material-based fertilizers. Conventional fertilisation techniques have resulted in inefficiencies and environmental problems because they often rely on chemical fertilisers for phosphorus (P) and nitrogen (N). Consequently, nanotechnology-based fertilizers—also referred to as nano fertilisers, or NFs—have become a promising therapeutic option. Compared to conventional fertilisers, these NFs enhance crop yields, improve nitrogen uptake efficiency, and have a smaller negative impact on the environment. This paper explores at the evidence, applications, and benefits of NFs, focusing on how they could change farming practices and enhance the production of sustainably produced food.
