They can be classified into different classes based on their properties, shapes or sizes. The catalytic properties of platinum nanoparticles have been studied by J. R. Applegate et al. But I presume youre more interested in fundamental reasons material properties change with size. For example, ferroelectric materials smaller than 10 nm can switch their magnetization direction using room temperature thermal energy, thus making them unsuitable for memory storage. Nanoparticles show different mechanical properties relative to microparticles and bulk materials, providing more effective options for the surface modification of many devices in the mechanical strength, or to improve the quality of nanomanufacturing/nanofabrication, etc. The properties of nanoparticulate substances are different from those of the same substance in bulk. Once the particle becomes similar in size to the wavelengths of light involved then quantum effects start to matter for how the particle behaves. While this diffusion property exhibited by nanoparticles may not affect the density of the product, it can lead to agglomeration. For example, we can get these particles as engineered particles, as incidental components and via natural sources. Copyright 2023 WisdomAnswer | All rights reserved.
