Surface roughness is a key factor for corrosion resistance in stainless steel, and products must conform to the European standard.
Atomic force microscopy (AFM) is a convenient way to analyse stainless steel surfaces and characterise the surface roughness according to ISO 25178.
In this report, three samples are analysed by using Tosca 400 – the new AFM from Anton Paar.
Scientists boost air pollution simulation
In the interest of factual accuracy, the commonly used particle sizes of concern for monitoring air pollution are PM10 and PM2.5, which are sub 10 and...
