Amine gases and formaldehyde (HCHO) have been used as typical indicators to monitor the quality of marine fish products. However, current detection methods are time-consuming and complicated to preprocess and have limitations such as high technicality requirements. Therefore, developing a sensor capable of simultaneously detecting multiple amine gases and HCHO with high performance in a simple way remains a significant challenge. In this paper, trimethylamine (TMA), dimethylamine (DMA), ammonia gas (NH 3 ), and HCHO were tested by a quartz crystal microbalance (QCM) gas sensor modified with a UiO-66/multiwalled carbon nanotube (MWCNT) nanocomposite. The sensor was operated at room temperature (25 °C) and fixed humidity (35% RH), and the results showed that the limits of detection of the QCM gas sensor for TMA, DMA, NH 3 , and HCHO were 0.32, 0.52, 1.02, and 2.4 μmoL L −1 , respectively. At the same time, our sensor could be reused more than ten times without degradation of sensor signals and showed high stability even after a long storage period of up to 2 months. The adsorption mechanism of the UiO-66/MWCNT nanocomposite-based QCM gas sensor toward the target gases was simulated. Ultimately, salmon meat was examined using the sensor that had been prepared, and the detection outcomes were contrasted with the findings from the Kjeldahl nitrogen determination. The results indicated that refrigerated salmon began emitting target gases on the second day and gradually increased thereafter. By the fifth day, the concentration of the target gases reached the point of complete spoilage. Our platform may be a promising platform for basic research and versatile practical applications in food quality assessments.

“…Due to the environmental problems related to the EC, this work pursues an alternative to detect and remove the drug o oxacin (OFL) in a simple, fast, and inexpensive way using of two adsorbents, zinc stannate (Zn 2 SnO 4 ) and reduced graphene oxide (rGO), because both the surfaces possess numerous applications in adsorptive process [18][19][20][21]. To better understand the stability and spontaneity of the adsorption process of OFL in both compounds (zinc stannate and reduced graphene oxide), theoretical calculations involving adsorption energy were performed [19,22,23].…”

Emerging Contaminants (ECs), such as pesticides, steroid hormones, antibiotics growth accelerators, and inhibitors of pathogenic microorganisms, among others, have become an increasingly severe and worrying problem to ecosystems and human health, including the contamination of water bodies. Therefore, it is imperative to seek ways to measure and evaluate the current conditions of various environmental matrices so that urgent strategies can be planned and designed to mitigate the spread of these contaminants. Ofloxacin, a widely prescribed antibiotic, is resistant to biological degradation and promotes bacteria resistance, being considered environmentally maleficent. In this sense, this work arises to theoretically study the adsorption of ofloxacin (OFL) on two surfaces (zinc stannate (Zn2SnO4) and reduced graphene oxide (rGO)), considering that OFL is classified as a toxic organic EC and, therefore, it is imperative to develop analytical methodologies for their removal. Furthermore, all theoretical calculations were carried out in the CASTEP software using Density Functional Theory (DFT) and the GGA functional, obtaining results for adsorption energy, band structure and Total Density of States (TDOS). The results showed that adsorption occurs more effectively with Zn2SnO4 (1 0 0), with an adsorption energy of -21.03 eV, compared to -1.90 eV in the rGO surface (1 0 0), and that the metallic character of this compound did not change after OFL adsorption. However, the OFL-Zn2SnO4 complex had more states to be occupied. Furthermore, it was observed that the OFL-rGO complex presented a greater semiconductor character.

Chemiresistive sensing lies in its ability to provide fast, accurate, and reliable detection of various gases in a cost‐effective and non‐invasive manner. In this context, graphene‐functionalized metal oxides play crucial role in hydrogen gas sensing. However, a cost‐effective, defect‐free, and large production schemes of graphene‐based sensors are required for industrial applications. This review focuses on graphene‐functionalized metal oxide nanostructures designed for gaseous molecules detection, mainly hydrogen gas sensing applications. For the convenience of the reader and to understand the role of graphene‐metal oxide hybrids (GMOH) in gas sensing activities, a brief overview of the properties and synthesis routes of graphene and GMOH have been reported in this paper. Metal oxides play an essential role in the GMOH construct for hydrogen gas sensing. Therefore, various metal oxides‐decorated GMOH constructs are detailed in this review as gas sensing platforms, particularly for hydrogen detection. Finally, specific directions for future research works and challenges ahead in designing highly selective and sensitive hydrogen gas sensors have been highlighted. As illustrated in this review, understanding of the metal oxides‐decorated GMOH constructs is expected to guide ones in developing emerging hybrid nanomaterials that are suitable for hydrogen gas sensing applications.
