“…In modern society, gas sensing is a crucial procedure in a variety of tasks, from contamination prevention to toxic molecule detection; all require the aid of gas sensors. − Various sensing materials, metal oxides, conducting polymers, and ceramics, for instance, − have been subjected to meticulous scrutiny. Additionally, sensing targets, such as humidity and toxic chemicals, have been extensively researched. − In particular, research toward high response and selectivity has gained huge interest; a sensitivity as low as 10 ppm has been observed, and a selecting response up to 4000 times its signal has been reported in previous literature. , While sensibility and distinguishability are critical areas of study, this work concentrates on the fundamental issue of the sensing mechanism and the inevitable matter of signal recovery.…”

Gas sensing research based on transition metal dichalcogenides (TMDs) suffers from irrecoverable responses. Prior attempts to improve the recoverability, such as applying heat to the material or using heterostructure designs, pose risks of damaging the surface or increasing sensor size. The ability to achieve repeatability is of the utmost importance in gas sensing research. In this study, we propose a novel approach that leverages the surface molecule trapping characteristic of TMDs to investigate gas adsorption on the material surface, which enables the repeatability of gas sensors. Our method involves regulating the gas sensing material surface by applying high concentrations of the target adsorbent to fill inactive sites on the material surface. To validate the effectiveness of our method, we introduced a two-trap model that combines physical and chemical adsorption. We applied various concentrations of the target adsorbent in different sequences, resulting in a highly linear relationship and repeatable outcomes. Our results demonstrate that there is a consistent relationship between the response and the target adsorbent, providing evidence that our method is capable of achieving repeatability for gas sensors. Therefore, our proposed method offers a promising solution to the challenge of irrecoverable responses and emphasizes the crucial importance of repeatability in the development of gas sensing technologies.

“…Accordingly, it has been possible to classify the quality of this important raw material with a good approximation [2][3]. Other studies have focused on classification processes to determine if the food is contaminated or fresh, such as chicken or fish [4][5][6][7]. Classification of some liquids, such as beer, alcohol and sesame oil, has been undertaken in other studies with good results [8][9][10].…”

Food companies worldwide must constantly engage in product development to stay competitive, cover existing markets, explore new markets, and meet key consumer requirements. This ongoing development places high demands on achieving quality at all levels, particularly in terms of food safety, integrity, quality, nutrition, and other health effects. Food product research is required to convert the initial product idea into a formulation for upscaling production with ensured significant results. Sensory evaluation is an effective component of the whole process. It is especially important in the last step in the development of new products to ensure product acceptance. In that stage, measurements of product aroma play an important role in ensuring that consumer expectations are satisfied. To this end, the electronic noses (enose) can be useful tools to achieve this purpose. The e-nose is a combination of various sensors used to detect gases by generating signals for an analysis system. Our research group has investigated the scent factor in some foodstuff and attempted to develop e-noses based on low-cost technology and compact size. In this paper, we present a summary of our research to date on applications of e-noses in the food industry.
