A New Piezo-Amperometric Sensing Method Based on Comb-like Nanostructured Zinc Oxide Thin Films for the Efficient Detection of Na2SO4

Energy Procedia, 2019
A chemical vapor deposition (CVD) was employed to deposit ZnO thin films on two different substrates, glass (quartz) and silicon. The characterization of structural properties of the comb-like nanostructure ZnO thin films were carried out through X-ray ...

The effect of SU-8 patterned surfaces on the response of the quartz crystal microbalance [PDF]

, 2005
In this work we present data showing the effect of patterning layers of SU-8 photoresist on a quartz crystal microbalance (QCM) and subsequent chemical treatment to increase their hydrophobicity. Patterns with 5 mu m diameter pillars spaced every 10 mu m
