Nano particles with a huge effect

Scientists have been studying nano particles (extremely small particles of less than 100 nanometers in diameter) for many years. On the basis of nano particles, new and innovative properties are developed, e. g. semiconducting or surface properties, such as the lotus effect, which open up possibilities previously unknown. There are various methods to produce nano particles. The “bottom up” technique involves synthesizing the particles from atoms and molecules. With the “top down” method, the particles are reduced to nanometer size by grinding. A suitable tool for this method is a planetary ball mill, such as RETSCH’s PM 100, PM 200 or PM 400, which provides the necessary energy input for grinding down to the nanometer range.
