Summary: Metal oxide-based thin-film sensors have been widely studied and commercialized for gas sensing applications, but they suffer from poor sensing response and high-temperature operation. In this study, a MoS2 decorated alpha-Fe2O3 thin-film-based gas sensor was demonstrated, which showed improved response and high sensitivity and selectivity towards NO2 gas.

Summary: This study presents a novel approach for the chemical decoration of chemically exfoliated MoS2 nanosheets with beta-hydroxyl organic pendant arms using the thiol-epoxide click reaction. The functional hybrids generated exhibit dangling organic groups directly proportional to the epoxide electrophilic character, allowing for additional functionalization steps. This method has been successfully applied for the first time on both phases (1T and 2H) of the model chalcogenide, providing functional samples suitable for further post-derivatization.

Summary: 2D materials can be functionalised with ionisable functional groups to form 2D electrolytes. In this study, heterostructures were formed by self-assembly of functionalised graphene oxide (GO) with cationic groups and molybdenum disulfide (MoS2) with anionic groups. The application of sonication allowed the continuous assembly of the 2D materials into heterostructured nanofibers, which resemble naturally occurring polyelectrolytes. This method offers a facile approach for the continuous processing of low-cost heterostructured nanofibers with potential applications in various fields.

Summary: A method to induce tensile and compressive strain into two-dimensional transition metal dichalcogenide (TMDC) MoS2 via deposition of stressed thin films is demonstrated, allowing for direct engineering of strain magnitude on a flake-to-flake level. Optically transparent stressors are chosen to probe MoS2 strain through Raman spectroscopy, showing layer-by-layer strain transfer. By using thin films with higher stress, strain can be engineered to be even higher, with negligible defects induced into MoS2 when thermal evaporation is used.

Summary: Chemical sensors based on solution-processed 2D nanomaterials are highly sensitive, capable of detecting NO2 gas at concentrations as low as 1 ppb, while bypassing traditional interflake interactions in favor of selectively extracting intraflake doping effects. This approach allows for an all solution-processed, flexible 2D sensor to be fabricated with similar sensitivity limits, and a thermal annealing strategy can further improve sensitivity by 2x at 200 degrees C.

Summary: The Mo cluster-MoS2 composite was synthesized through a one-step sulfurization process using H2/H2S gas flow. The decomposed Mo-6 cluster iodides acted as a template and precursor, forming complex Mo cluster compounds and eventually producing MoS2. After sulfurization, the response of the composite to NH3 gas increased three times while showing conversion from p-type to n-type semiconductor, enhancing its potential for device applications.

Summary: A novel 2D/0D MoS2/ZnS based gas sensor was designed for high-performance detection of NO2 gas at room temperature, showing enhanced response performance, complete recoverability, ultra-low detection limit, high selectivity, and outstanding stability. The improved gas sensing performance is attributed to the unique structure and synergistic effects between MoS2 nanosheets and ZnS nanoparticles in terms of geometry, charge transfer, equivalent resistance, and chemistry. This work offers a promising approach for the fabrication of high-performance gas sensing materials for environmental monitoring at room temperature.

The hybrid aerogels exhibited excellent microwave absorbing performance, with high absorption capacity and broad effective absorption bandwidth. The improved microwave attenuation is attributed to proper component, multiple heterogenous interface, and hierarchical porous structures.

Summary: In this research, ultrathin films of spin-crossover materials were grown on 2D materials, and the properties and spin transition of these hybrid structures were studied. When using 2H MoS2 as the substrate, the spin transition in films thinner than 8 nm was hindered by Fe3+; while using 1T MoS2, the spin transition was preserved in films as thin as 4 nm.

Summary: This study systematically investigates the dispersibility of MoS2, WS2 and MoSe2 in aqueous medium using cationic and anionic dispersants, providing insights on the influence of metal type, chalcogen type, surfactant charge, and concentration on exfoliation and stabilization. The methodology yields well-exfoliated nanosheets with controlled lateral dimension and thickness. Different profiles of dispersibility curves are proposed based on the type and concentration of ionic surfactants.

Summary: 2D boron nitride (BN) and molybdenum disulfide (MoS2) materials have novel chemical, electronic, and optical properties, but recent research has shown potential hazards of MoS2 under certain biological conditions. MoS2 induces dose-dependent cytotoxicity in Kupffer cells (KCs), while the BN derivatives are non-toxic. The toxicity of MoS2 is attributed to nanosheet dissolution and the release of hexavalent Mo, leading to mitochondrial reactive oxygen species generation and apoptosis in KCs. Further, the phagocytosis of MoS2 aggregates triggers a separate response pathway involving lysosomal damage, NLRP3 inflammasome activation, and cytokine production.
