Combination of Quartz Crystal Microbalance with other Techniques

2008
As implied by its acronym, the quartz crystal microbalance was first used to determine the mass of material deposited on its surface. A heuristic description of the linear relation between the change in its resonant frequency Δf, from its unloaded resonant frequency f 0 , and the mass density, m’, was recognized by Sauerbrey [1] and led to the now ...

Electrospun zinc oxide nanofibers for UV sensing with quartz crystal microbalance technique

International Journal of Modern Physics B, 2021
An ultraviolet (UV) sensor consisting of a zinc oxide (ZnO) nanofiber sensing membrane and a quartz crystal microbalance (QCM) was fabricated. ZnO nanofibers were prepared by electrospinning and calcination. The morphology and structure of the nanofiber sensing membrane were characterized by scanning electron microscopy and X-ray diffraction.

In Vitro Haemocompatibility Evaluation of PET Surfaces Using the Quartz Crystal Microbalance Technique

Journal of Biomaterials Science, Polymer Edition, 2012
Owing to the complex influences of several experimental conditions on the in vitro alteration of blood, there is still a lack of viable in vitro tests and methods for blood compatibility evaluation of biomaterials. The aim of this research was to study a new approach for the haemocompatibility assessment of differently modified PET surfaces using the ...

Lectin typing of Campylobacter jejuni using a novel quartz crystal microbalance technique

Analytica Chimica Acta, 2011
Seven Campylobacter jejuni strains were characterised by a lectin typing assay. The typing system was based on a quartz crystal microbalance technique (QCM) with four commercially available lectins (wheat germ agglutinin, Maackia amurensis lectin, Lens culinaris agglutinin, and Concanavalin A), which were chosen for their differing carbohydrate ...

Detection of human fibrin by immunological piezoelectric quartz crystal microbalance technique

Wuhan University Journal of Natural Sciences, 1997
The detection of human fibrin has been performed by immunological piezoelectric quartz crystal microbalance technique. Anti-fibrin antibody was immobilized onto the gold electrodes of a 9 MHz AT-cut piezoelectric quartz crystal with bovine serum albumin adsorption, followed by glutaraldehyde cross-linking.

Quartz-Crystal Microbalance Technique for the Preparation of Alkali-Antimonide Photocathodes

Journal of Applied Physics, 1968
A quartz-crystal microbalance technique has been developed which measures the chemical composition of an alkali-antimonide film during photocathode formation at the normal photocathode processing temperatures. It is possible to measure continuously and simultaneously the chemical composition, photoelectric emission, resistance, and optical transmission

In-situ monitoring technique for growth of CdS layer by quartz crystal microbalance

2008 33rd IEEE Photovolatic Specialists Conference, 2008
Quartz Crystal Microbalance (QCM) was applied to chemical bath deposition (CBD) process to improve the controllability of the CdS deposition and to get more reproducible results. The frequency change measured by QCM during CdS deposition process was turned out to have linear relationship with thickness of the CdS thin films, while the traditional ...

Solubility of carbon dioxide in polymers by the quartz crystal microbalance technique

The Journal of Supercritical Fluids, 1998
The use of a quartz crystal microbalance (QCM) has been demonstrated to be an accurate and relatively easy technique to measure gas solubility in polymers at high pressures. The technique is reversible and could be used for real-time monitoring of a process.

Glassy polymer‐sorption phenomena measured with a quartz crystal microbalance technique

Journal of Polymer Science Part B: Polymer Physics, 2003
AbstractThe quartz crystal microbalance (QCM) method is applied to the measurement of CO2 sorption in glassy poly(ethylene terephthalate) (PET), poly(methyl methacrylate), and polysulfone. Polymer thin films in the thickness range of 350–550 nm are prepared by spin‐casting onto the quartz crystal devices.

Following Polymer Brush Growth Using the Quartz Crystal Microbalance Technique

Macromolecular Rapid Communications, 2005
AbstractSummary: The growth of surface‐initiated poly([2‐(methacryloyloxy)ethyl]trimethylammonium chloride) (pMETAC) brushes by ATRP was monitored by the quartz crystal microbalance technique with dissipation (QCM‐D). The change in mass of the quartz crystals starting from the adsorption of a thiol initiator monolayer through to the growth of the ...
