What are the effects of different types of nano silicates on the material?
Best insight from top research papers
Different types of nano silicates have various effects on the material. The use of nano-silica in self-compacting concrete (SCC) improves its durability properties, with colloidal nano-silica showing higher reactivity at early age . In ultra-high strength concretes, nano-silica enhances mechanical performance by improving compressive and flexural strengths through the packing effect and pozzolanic reaction . In two-component polyurethane clear coats, nano silica particles affect rheometric behavior, hardness, and scratch depth, with hydrophobic nano silica providing acceptable haze values . For acrylic-melamine automotive clear coats, the addition of nano-layered silicate particles improves chemical and physical properties, with 1-2 wt% resulting in desired improvements while higher percentages can cause damage to certain properties . In acrylic-based polyurethane nano-composites, precipitated and fumed nano-silica particles enhance adhesive strength, micro-hardness, and erosion resistance, with precipitated nano-silica offering a cost-effective alternative to fumed clearcoats .

How do different plant species are affected by nanoparticles?5 answersDifferent plant species are affected by nanoparticles in various ways. Some studies have shown that silver nanoparticles can intensify the allelopathic intensity of invasive plant species, such as Conyza canadensis, Erigeron annuus, Bidens pilosa, and Aster subulatus, on the seed germination and seedling growth of lettuce. Cerium oxide nanoparticles have been found to be taken up by plant roots and translocated to leaf tissues, affecting the growth of Holcus lanatus and Diplotaxis tenuifolia differently. Nanoparticles can cause changes in plants at morphological, physiological, genetic, and epigenetic levels, potentially affecting plant growth and nutrition. Plant exosome preparations derived from different medicinal plants, such as Kalanchoe daigremontiana, Artemisia absinthium, Hypericum perforatum, Silybum marianum, Chelidonium majus, and Scutellaria baicalensis, have shown variations in nanoparticle yield, size distribution, and antioxidant activities. Various nanoparticles, including CNT, Ag-NPs, TiO2-NPs, Au-NPs, and ZnO-NPs, have been found to enhance the growth of different plant parts and crop production when used in proper concentrations.
How nanomaterials impact different plant species on soil?5 answersNanomaterials (NMs) have a significant impact on different plant species in soil. The introduction of NMs into the soil can lead to diverse responses in enzymatic activities of beneficial microbes, which in turn affects plant performance and soil resource components. The presence and persistence of NMs in the soil can alter biologic processes, promote changes in plant growth, and turn plant diseases into toxicological effects throughout the food chain. Engineered nanoparticles (ENPs) in soil modulate microbial diversity, soil properties, and plant growth, resulting in anomalies in soil properties and plants. Nanomaterials impose physical and chemical effects on microorganisms and plants, with microorganisms being more susceptible to NMs than plants. Nanomaterials induce responses from biostimulation to toxicity in plants, depending on their physical and chemical characteristics, the biological species they interact with, and the form and route of application.
What is the effect of nanoparticles on soil morphology?5 answersNanoparticles (NPs) have a significant impact on soil morphology. The introduction of various types of NPs in soil leads to diverse responses in enzymatic activities of beneficial microbes, which can modulate the activity of soil microbiota and negatively impact soil fertility and crop productivity. Nanoparticles in soil greatly affect the chemical processes in the soil system, including separation, identification, fate, interactions, and effects on soil systems. The exposure of soil to nanoparticles causes a decrease in soil microbial biomass and enzymatic activity, impacting microbial community composition and biological diversity. Understanding the soil voids areas and their interconnection is helpful in understanding phenomena such as transport in porous media, water retention, fluid flow, soil contamination, and filtration. Nanoparticles can also exert toxicological impacts on plant physiology, affecting various plant health parameters in a size- and concentration-dependent manner.
How does nanosilica impact the strength of asphalt?4 answersNanosilica has a positive impact on the strength of asphalt. It improves the distribution of the catana phase, increases the size of the bee structure, and enhances the surface roughness of the asphalt binder. The addition of nanosilica into base and zycotherm binders improves temperature susceptibility and storage stability at elevated temperatures. Nanosilica also enhances the stiffness of modified binders and improves the rutting potential. In rubberized asphalt mixtures, nanosilica reduces the global warming potential and increases the fatigue life of the composite mixtures. In asphalt emulsion mixtures, nanosilica improves the moisture susceptibility, increases the indirect tensile strength, and compressive strength of the samples. When used in conjunction with reclaimed asphalt pavement (RAP) materials, nanosilica increases the rutting resistance and resilient modulus of SMA mixtures. However, the low-temperature performance of binders may be decreased when modified with nanosilica, especially in binders containing RAP materials.

Additionally, nanomaterials can enhance the resistance of bitumen to permanent deformation, improving its durability. Nanoscale materials exhibit unique physical properties, such as magnetic, optical, mechanical, and electrical properties, which can be manipulated and engineered. These properties make nanomaterials promising candidates for various applications, including communications, electronics, energy, and healthcare.
What are the effects of nanoparticles on the environment?2 answersNanoparticles have various effects on the environment. They can inhibit the growth of microbes and disrupt cell membranes, leading to cell death. Nanoparticles, such as ceria (CeO2), added to fuels can reduce toxic emissions and improve engine performance, but their impact on the ecosystem and human health is still a concern. Nanoparticles in the Earth's surface systems have abnormal properties like migration, aggregation, and adsorption effects, which can affect the environment and resource enrichment. Green nanotechnology, which utilizes the concept of green chemistry and engineering, aims to minimize health and environmental risks by developing clean technologies and using renewable inputs. Overall, nanoparticles have both positive and negative effects on the environment, and further research is needed to fully understand their impact.
