Summary: This Letter presents the fabrication of large-scale few-layered MoS2 on sapphire using physical vapor deposition, and investigates its nonlinear saturable absorption properties. The as-grown MoS2 membrane exhibits high modulation depth and saturable intensity, making it a suitable saturable absorber for passive Q-switching in laser applications. This work demonstrates the potential of two-dimensional MoS2 for mid-infrared photonic devices.

Summary: In this study, layered MoS2 was produced using a hydrothermal method and characterized in detail. The experimental results showed that MoS2 exhibited excellent catalytic activity in bromophenol blue degradation. The preparation method of MoS2 improved light harvesting, prevented fast charge recombination, and created suitable electron transfer sites for photocatalytic reactions.

Summary: This work focuses on synthesizing hybrid nanocomposite electrode materials for supercapacitor applications. The performance of different hybrid electrode materials, such as MoS2/CNTs, TiO2/CNTs, and MoS2/TiO2/CNTs, was enhanced by incorporating carbon nanotubes (CNTs) into MoS2 and TiO2. The synthesized MoS2/TiO2/CNTs exhibited superior electrochemical performance compared to other hybrid electrode materials, with a higher specific capacitance and lower overall impedance. It also displayed good cycling stability and high energy and power densities.

Summary: The efficiency of Fe3O4-MoS2 nanosheets synthesized through hydrothermal process and its fabrication with chitosan (Fe3O4-MoS2@CS) in removing Cr(VI) and ciprofloxacin (CIP) from simulated wastewater was evaluated. The nanohybrid materials were characterized and their selectivity for different metal ions was studied. Fe3O4-MoS2@CS showed high selectivity for Cr(VI) and enhanced removal efficiency for CIP. The adsorption process was influenced by pH and followed the Langmuir isotherm model.

Summary: Chemically exfoliated MoS2 nanosheets have been widely used in biomedical and environmental fields, but may induce toxicity, especially affecting DNA directly, which sets it apart from other two-dimensional nanomaterials. The study found that the ability of ce-MoS2 to induce DNA cleavage is related to pH value and light irradiation conditions, providing new insights into its potential risks and toxicity in aquatic environments.

Summary: By conducting nose-only inhalation tests on mice, we found that the air concentration of molybdenum disulphide particles has no observed adverse effect on body weight gain and genotoxicity below 13mg/m³, while the effects on respiratory function suggest this level as the lowest observed adverse effect concentration.

Summary: The thickness and orientation of MoS2 components significantly affect the photocatalytic activity of MoS2-based heterostructures. A new facile two-step carbothermal-reduction-assisted CVD synthesis method was reported to produce MoS2 nanosheets on activated carbon granules, and the results showed that the thickness and orientation of MoS2 nanosheets play a crucial role in the photocatalytic activity.

Summary: This work presents a novel nickel@nitrogen-doped graphene@MoS2 (Ni@N-Gr/ MoS2) triad heterostructure for catalytic HER. The as-synthesized Ni@N-Gr/MoS2 assembly exhibits high intrinsic HER activity and stability, thanks to the incorporation of Ni@N-Gr in the basal plane of MoS2 and the improvement of conductivity by nitrogen-doped graphene.

Summary: High-performance photocatalysts are crucial for harvesting solar energy and producing pollution-free hydrogen and oxygen through water splitting. In this study, we designed 144 van der Waals (vdW) heterostructures by combining different two-dimensional (2D) group III-V MX (M = Ga, In and X = P, As) monolayers to identify efficient photoelectrochemical materials. Using first-principles calculations, we investigated the stabilities, electronic properties, and optical properties of these heterostructures. GaP/InP in a BB-II stacking configuration was selected as the most promising candidate, with a type-II band alignment and suitable gap value for the catalytic reaction under pH = 0. Additionally, the construction of vdW heterostructure improved light absorption. These findings provide insights into the properties of III-V heterostructures and can guide experimental synthesis for photocatalysis applications.

Summary: In this article, a novel LDH/MoS2 hybrid material was synthesized using a hydrothermal method. The LDH/MoS2 hybrid material significantly enhanced the fire safety of TPU composites by reducing the heat release rate, smoke release rate, and toxic gas emissions. The improved flame retardancy was attributed to the catalytic carbonization of LDH and the physical barrier effect of MoS2.

Summary: Transition metal dichalcogenides (TMDs) have emerged as promising materials for electrocatalysis, especially for the hydrogen evolution reaction (HER). In this study, the morphological and (electro)chemical changes of synthetic bulk crystals of MoS2, TiS2, and TiSe2 during HER were investigated. The results showed different degrees of corrosion in these materials, with TiSe2 > TiS2 > MoS2.
