In materials with nanoscale dimensions the surface or interface properties dominate over the bulk properties. The very large surface area of these materials may result in novel physical and chemical properties, such as increased catalytic activity, improved solubility or different optical behavior.
Used to enhance the performance of products and technologies, nanomaterials are already found in a wide variety of consumer products, such as textiles, paints, sunscreens and other healthcare products. Intensive research is being done in the use of nanomaterials for energy storage and energy conversion, pharmaceuticals, life science applications, solar cells, catalysis, and composite materials, to name a few. Potential nanotoxicity and nanosafety concerns have resulted in a growing number of nano-regulations.
Control over nanoparticle size distribution and nanoparticle shape, surface properties and dispersion, aggregation stability as well as over elemental and nanocrystalline composition is often crucial for designing new materials for specific applications. Nanofilm thickness, roughness and layer properties are critical parameters in thin film applications.
Malvern Panalytical offers a range of solutions to support research and development in nanoscience and nanotechnology. X-ray and laser light scattering/diffraction enables to reveal and verify dimensions and structures in all types of nanomaterials. Our X-ray fluorescence spectrometers allow to analyze elemental compositions, e.g. the concentration of doping agents. Nanoparticle tracking analysis is used e.g. as a tool in nanotoxicological studies and for nanoparticle concentration determination, as well as to investigate whether a given sample is classified as a nanomaterial, according to latest definitions.
