Brownian motion method for measuring the temperature of nanoscale objects
Temperature Measurement and Thermometry : 14 May, 2014
Pioneering research has now developed a method to accurately measure the surface temperature of nanoscale objects when they have a different temperature than their environment. A team led by Dr Janet Anders at the University of Exeter and Professor Peter Barker at University College London have discovered that the surface temperatures of nanoscale objects can be determined from analysing their jittery movement in air - known as Brownian motion.
 
Precise thickness measurement of soft materials by means of contact stylus instruments
Thickness Measurement : 16 September, 2013
In microsystems, metallic components are increasingly replaced by components made of inexpensive polymers. As polymers yield when they are subjected to pressure, the layer thicknesses cannot be measured with sufficient accuracy by means of conventional contact stylus instruments. But precision is of decisive importance in microsystem technology. Scientists of the Physikalisch-Technische Bundesanstalt (PTB) can measure the thickness of soft polymer layers on hard substrates and correct their measurement results by means of a formula.
