Multichannel Quartz Crystal Microbalance
Analytical Chemistry, 1999Arrays of quartz crystal resonators are fabricated on a single quartz wafer as a multichannel quartz crystal microbalance (MQCM). Three types of four-channel array of 10-MHz resonators are prepared and tested. Mechanical oscillation of each channel is entrapped within the channel almost completely, so that the interference between the channels via the ...

Review of Scientific Instruments, 2009
A novel device for nanometer-confinement of soft matter in one dimension (1D) is presented. This nanocell, with very large (up to 106:1) cell-radius to cell-height ratio, is tailored as an accessory for quartz crystal microbalance (QCM) and QCM with dissipation-monitoring (QCM-D) sensing to study internal and interfacial energy dissipation phenomena in

Proximity Effect in Quartz Crystal Microbalance
Analytical Chemistry, 2008When an object approaches a vibrating quartz crystal microbalance (QCM) the resonant frequency changes. This "proximity effect" was seen at the distance of 10 mm in air and became more pronounced as the distance decreased. This effect depends on the quality factor (Q-factor) value of a QCM, conductivity of the object, and electrical connection of the ...

The Quartz Crystal Microbalance as a Nanotribology Technique
2007The quartz crystal microbalance (QCM) technique is a powerful probe of interfacial phenomena that has been successfully employed to investigate the sliding friction of objects of nanoscopic size subject to lateral speeds as large as a few m/s. After a description of the quartz acoustics, the chapter presents the more common circuits used to drive the ...

Development of a magnetic quartz crystal microbalance
Review of Scientific Instruments, 2007A new technique for measurement of magnetic properties of materials is demonstrated. It can be used for the measurement of thin magnetic films during their chemical modification. The resonance frequency of a quartz crystal microbalance (QCM) with conducting polymer (polyaniline) suspension in poly(ethylene glycol) was observed to increase with ...

A Survey of the 2010 Quartz Crystal Microbalance Literature
Journal of Molecular Recognition, 2012In 2010 there has again been an increase in the number of papers published involving piezoelectric acoustic sensors, or quartz crystal microbalances (QCM), when compared to the last period reviewed 2006‐2009. The average number of QCM publications per annum was 124 in the period 2001‐2005, 223 in the period 2006‐9, and 273 in 2010.

Multimode Quartz Crystal Microbalance
Japanese Journal of Applied Physics, 2000In this paper, a quartz crystal microbalance (QCM) gas sensor using multiple resonant modes is studied. In this QCM gas sensor, the absorbent is not fully deposited onto the plate surface as in the case of conventional QCM gas sensors.

The Quartz Crystal Microbalance (QCM) as an lmmunosensor
2003This chapter demonstrates a preliminary experimental approach to detect antiviral antibodies by means of a quartz crystal immunosensor. As an example of the large numbers of immunoassays currently applied in the clinical laboratory, the screening for human immunodeficiency virus (HIV) specific antibodies was presented as a model application. The quartz
