Special Issue Information

Dear Colleagues,

Recent advances in sources and detectors in the TERA-MIR field: THz (0.3 THz to 10 THz) and Mid Infrared (10 THz to 100 THz) have shown that there are a large number of applications in physics, electrical engineering and technology, applied chemistry, materials sciences, and medicine/biology that would benefit from spectroscopy and imaging with frequencies in both ranges. Even more recently, novel devices in the GIGA range from 0.1 THz to slightly below 0.3 THz, notably in medical diagnostics based on sensitive gas detection and imaging, make a review on materials, sources, and detectors for the GIGA-TERA-MIR range timely to help identify common aspects within a synergetic approach. The main emphasis of this Special Issue will be on new fundamental material properties, concepts and device designs that are likely to open the way for new products or the exploitation of new technologies in the fields of sensing, healthcare, biology, and industrial applications. The topics covered in this Special Issue will be of interest to research centers, academic institutions, and well-established and start-up companies and hospitals.

The onset of scaling in oil pipelines can halt or drastically reduce oil production, causing huge financial losses and delays. Current methods used to monitor scaling can take weeks, while the scaling process only takes few hours. The proposed sensor is designed for online monitoring of strontium ions concentration in seawater as an early scaling indicator. The sensor operates in the GHz range by probing the shift in the resonance frequency due to changes in the ionic concentrations of the medium. The results show selective sensitivity to changes in the strontium ions concentration even in the presence of many other ions found in seawater. The measured sensitivity is found to be stable and linear with a detection level of better than 0.08% (0.042 mol/L) of strontium ions in seawater. This work demonstrates a robust GHz sensor for strontium sulfate scale monitoring and early detection, which could be used in the oil industry to prevent huge production losses. These results could also be extended further to target the monitoring of other ions in different industrial sectors. Full article
