TL;DR: In this article, the authors summarize the recent progress on QCM gas sensors and QCM humidity sensors based on graphene materials and graphene composites, and the challenges for future works related to the development of QCM sensors coated by graphene materials or graphene composite materials.

TL;DR: This study shows that solvent vapor treatment offers a simple and inexpensive method that provides excellent results and is a promising alternative treatment for use in increasing the mechanical properties of electrospun nanofibers.

TL;DR: In this article, a PAN/PEI nanofiber-functionalized quartz crystal microbalance (QCM) sensors were developed for humidity sensing, which exhibited a sensitivity of up to 164 Hz/%rH with the response and recovery times of 13 and 7 s, respectively, during humidity exposure assessments performed at room temperature of 30 ± 1) °C.

TL;DR: In this paper, a quartz crystal microbalance (QCM)-based sensor was used for the analysis of short-chain VOCs. But the QCM sensing chip was exposed to humidity because water vapor significantly interferes with QCM gas sensing.

TL;DR: In this paper, highly sensitive and selective ammonia gas sensors based on quartz crystal microbalance (QCM) platforms were functionalized with electrospun polyvinyl acetate (PVAc) nanofibers.
