Special Issue Information

Dear Colleagues,

The world is evolving rapidly. Changes are disruptive and sometimes utterly devastating. Technologies are evolving quickly, as well as data processing systems. The number of measured data is always greater, but in almost all cases, they are related to a single, specific action that does not characterize the entire system. To monitor and control changes, alterations, and effects, the research challenge is to systematize, synthesize, and index complex ecosystems with innovative tools. The definition and introduction of a footprint, as an analytical indicator, is in this sense a challenge of modern science. A footprint which, determined through the use of instrumental sensors, is called a fingerprint. A fingerprint which, determined with intelligent systems and continuously and dynamically updated, can act as a proactive tool to avoid various impacts and, through the adoption of IoT actions, to control industrial processes and/or sources. This Special Issue focuses on the study and development of these innovative systems which, through the measurement of multiple gaseous compounds, allow for the monitoring of complex systems, managing to characterize and define a fingerprint for control purposes. This Special Issue aims to collect original research and review articles on recent advances, technologies, solutions, applications, and new challenges in the field of advanced and smart instrumental systems for the monitoring and active control of GHG, VOCs, and environmental odours.

Chemical sensors, relying on changes in the electrical conductance of a gas-sensitive material due to the surrounding gas, typically react with multiple target gases and the resulting response is not specific for a certain analyte species. The purpose of this study was the development of a multi-sensor platform for systematic screening of gas-sensitive nanomaterials. We have developed a specific Si-based platform chip, which integrates a total of 16 sensor structures. Along with a newly developed measurement setup, this multi-sensor platform enables simultaneous performance characterization of up to 16 different sensor materials in parallel in an automated gas measurement setup. In this study, we chose the well-established ultrathin SnO2 films as base material. In order to screen the sensor performance towards type and areal density of nanoparticles on the SnO2 films, the films are functionalized by ESJET printing Au-, NiPt-, and Pd-nanoparticle solutions with five different concentrations. The functionalized sensors have been tested toward the target gases: carbon monoxide and a specific hydrogen carbon gas mixture of acetylene, ethane, ethne, and propene. The measurements have been performed in three different humidity conditions (25%, 50% and 75% r.h.). We have found that all investigated types of NPs (except Pd) increase the responses of the sensors towards CO and HCmix and reach a maximum for an NP type specific concentration. Full article
