What is Dissipation?

Talking about QCM-based instrumentation, one often comes across the concepts of ‘dissipation’ or ‘damping’. Learn more about what these concepts mean, and why are they relevant.

What is a Viscoelastic material?

Viscoelasticity is a quality involving both viscous and elastic properties at the same time. QCM-D is a surface-sensitive technology that can characterize the viscoelastic properties of thin films.

What is QCM-D?

QCM-D, Quartz Crystal Microbalance with Dissipation monitoring, is an extended version of QCM, and is particularly suitable for the characterization of soft layers.

What is QCM?

Quartz Crystal Microbalance, or QCM, is essentially a balance for very small masses which enables time-resolved characterization of thin and rigid layers.

What is the difference between QCM-D and traditional QCM?

The QCM with an added D measures an additional parameter, the dissipation factor. The QCM-D provides more information about the system under study than traditional QCM.

What does QCM-D have in common with a church bell?

How does QCM-D work? Perhaps you know that a QCM-D sensor is made out of quartz, which is a piezoelectric material. Read about what that means.
