Nanoparticles

Particles with sizes in the nm- and µm-range find application in diverse fields of research and industry such as catalysis, drug delivery, sensing or optoelectronics. The materials properties and hence application performance are affected by the particle size, shape, surface characteristics as well as by possible pore or defect structures. Tuning the parameters of the chosen synthesis technique can affect some or all of these properties and thus enables the tailoring of the particle function. As the particle design rises in complexity, a detailed analysis of their properties like crystallinity, chemistry or morphology using the broad spectrum of different TEM techniques gets even more important.
