“…Transition metal dichalcogenides (TMDCs) are currently causing a stir in the gas field due to their outstanding semiconductor performance, abundant porosity, and layered structure. − Among these materials, WS 2 stands out with its small band gap of 2.231 eV and high room-temperature carrier mobility (monolayer >20 cm –1 V –1 s –1 ), making it superior to other TMDCs. , Recent experimental investigations have unveiled the promise of employing intrinsic WS 2 for detecting SF 6 decomposition gases, highlighting its inherent capabilities in this realm. Chen et al found that the pom-pom WS 2 showed high linearity ( R 2 > 0.99) for four decomposed gases, namely H 2 S, SO 2 , SOF 2 , and SO 2 F 2 , at a low concentration (50 ppm).…”

At high temperatures, the rapid and effective detection of SF 6 decomposition gas is a major challenge. Therefore, online detection of SF 6 decomposition gas at high temperatures for Gas Insulated Switchgear fault diagnosis is necessary. In this work, first-principles calculations are used to examine the adsorption and sensing properties of pristine WS 2 and transition metal Co, Rh, and Ir-modified WS 2 toward H 2 S, SO 2 , SOF 2 , and SO 2 F 2 . Our study delved into the adsorption energy and mechanisms of each system, exploring various aspects including adsorption energy, band gap, electron density, frontier orbital theory, conductivity, and recovery time. The findings indicate that the transition metal Co, Rh, and Irmodified WS 2 surface exhibits excellent adsorption capabilities for the decomposed gases. Co-WS 2 has good sensing performance for H 2 S, SO 2 , and SOF 2 and can achieve faster desorption for these three decomposed gases at high temperatures (598 K). SO 2 F 2 can be desorbed rapidly (0.65 s) from the surface of Rh-WS 2 at room temperature, and Rh-WS 2 has good selectivity for SO 2 F 2 . Interestingly, Ir-WS 2 remains difficult to desorb even at high temperatures for H 2 S (−2.642 eV), SO 2 (−2.260 eV), SOF 2 (−1.945 eV), and SO 2 F 2 (−2.841 eV) and can be used as a scavenger for these four gases. Therefore, the simulation experiments in this study aim to investigate the advantages of transition metal Co, Rh, and Ir-modified WS 2 for detecting SF 6 decomposition gases.

“…Given that physiological bone repair involves piezoelectric and flexoelectric voltage changes within the bone extracellular matrix, TMDs hold potential for bone regeneration applications. Additionally, the single- to few-layered TMDs exhibit optical bandgaps that facilitate their application in photothermal therapy, which, when combined with multimodal imaging techniques, makes them efficient treatment modalities for targeting tumors. − Transition metal oxides (TMOs) like MnO 2 and TiO 2 serve as targeted drug delivery vehicles and components of nanocomposite hydrogels designed to mimic the extracellular matrix (ECM) of articular cartilage. Their high specific surface area and modulus values enable controlled release of adsorbed drugs. − …”

The development of advanced technologies for the fabrication of functional nanomaterials, nanostructures, and devices has facilitated the development of biosensors for analyses. Two-dimensional (2D) nanomaterials, with unique hierarchical structures, a high surface area, and the ability to be functionalized for target detection at the surface, exhibit high potential for biosensing applications. The electronic properties, mechanical flexibility, and optical, electrochemical, and physical properties of 2D nanomaterials can be easily modulated, enabling the construction of biosensing platforms for the detection of various analytes with targeted recognition, sensitivity, and selectivity. This review provides an overview of the recent advances in 2D nanomaterials and nanostructures used for biosensor and wearable-sensor development for healthcare and healthmonitoring applications. Finally, the advantages of 2D-nanomaterial-based devices and several challenges in their optimal operation have been discussed to facilitate the development of smart highperformance biosensors in the future.
