The detection and measurement of trace gas concentrations is crucial for the understanding and monitoring of chemical and physical processes for a wide variety of applications, such as environmental monitoring, industrial process control, combustion processes, medicine, detection of toxic and flammable gases, as well as explosives. Laser-based spectroscopic techniques for trace gas detection are capable of high sensitivity and selectivity. These features are required in atmospheric science for the monitoring of different trace gas species including greenhouse gases and ozone, and in breath diagnostics to detect nitric oxide, ethane, ammonia and numerous other biomarkers. For the in-situ and real time measurements, the high sensitivity and selectivity must be combined with compactness and robustness of the sensors. In this landscape, photoacoustic and photothermal spectroscopy based on quartz tuning forks (QTF) have been proving through the last 15 years all the advantages of avoiding the use of optical detectors by employing acoustic resonators, which are immune to environmental noise and wavelength insensitive.
The present Special Issue was conceived with the aim of collecting and connecting all the provided contributions, works and analysis that are currently pushing quartz-enhanced photacoustic and phototermal spectroscopy to the state of art. The topics of focus will embrace the new generation of custom resonators, novel experimental approaches, smart solutions to real-world challenges, as well as theoretically-oriented issues, such as simulation of QTF vibrational dynamics, analysis of broadband absorbers, the effects of gas matrix changes, and gas relaxation dynamics.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2300 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
