Summary: This study explores the CO2 adsorption behaviors of Mo2C MXene for the first time. The sample prepared with LiF + HCl etching exhibits the highest capacity and stronger interaction with CO2. Despite having a lower specific surface area compared to other MXenes, Mo2C MXene shows better CO2 capture performance due to physical absorption formed by capillary condensation in mixed pores and slitlike pores. Additionally, the CO2 adsorption on the surface of Mo2C MXene with functional groups (O or F) shows a chemisorption feature.

Summary: 2H-MoS2 is a promising semiconductor with earth-abundant nature, low toxicity, and low cost. Although it has demonstrated good catalytic activity in various energy-related processes, its application in catalysis for C-C bond forming reactions in organic synthesis remains largely unexplored. The challenges arise from the difficulty of using bulk 2H-MoS2 due to its low surface area, which requires high catalytic loadings for acceptable yields and makes the optimization process expensive and tedious. In this study, we developed a 2H-MoS2-mediated synthesis of valuable bis(indolyl)methane derivatives and optimized the reaction conditions using the Design of Experiments method.

Summary: Two-dimensional heterostructures have attracted widespread attention due to their potential applications in optoelectronic devices and novel physical effects beyond conventional bulk electronics. However, the optical properties of 2D lateral heterojunctions have not been fully characterized due to limitations in spatial resolution, requiring nano-optical techniques. In this study, we used subdiffraction limited tip-enhanced photoluminescence (TEPL) spectroscopy with sub-nanometer tip-sample distance control to investigate lateral monolayer WS2-MoS2 heterostructures. We observed significant photoluminescence enhancement by placing a plasmonic Au-coated tip at the resonantly excited heterojunction.

Summary: In this study, a synergetic effect of atomic-interface engineering was utilized to enhance the reversible capacity of sodium-ion batteries. The 2H-MoS2 layers were assembled on single atomically dispersed Fe-N-C anode material via Fe-S bonds, which enhanced the adsorption of Na+. During the sodiation/desodiation process, a phase transfer from 2H to 1T/2H MoS2 occurred, accompanied by ferromagnetic spin-polarization of SA Fe-N-C, leading to improved Na+ storage kinetics.

Summary: The study found that C/Mullite composites annealed in an inert atmosphere exhibited better thermal stability compared to those annealed under a vacuum, with carbothermal reduction being the main factor for failure. The activation temperature of carbothermal reduction in the inert atmosphere was approximately 100 degrees C higher than in the vacuum, leading to irreversible degradation of mechanical properties once activated and destruction of the microstructure.

Summary: Two-dimensional MoSe2 nanosheets were found to have higher activity than MoS2 nanosheets as catalysts for nitroarene reduction in water treatment. Density functional theory (DFT) calculations revealed the reduction pathway on 2D MoSe2 and explained the selectivity displayed by the catalyst. The MoSe2 nanosheets were further coated with colloidal stabilizers and immobilized on polymer foam for practical application, showing no significant loss of activity after multiple catalytic cycles.

Summary: The differences between carbothermal reduction and graphenothermal reduction of metal oxide and graphite or graphene systems have not been thoroughly investigated. In this study, the relationship between crystalline growth and chemical reduction during the heat-treatment of reduced graphene oxide (RGO) and NiO nanoparticles was investigated. The heat-treated RGO/NiO mixtures showed complex interactions, where below a critical NiO concentration, the crystalline growth of RGO and NiO took precedence, and above this threshold, drastic Ni formation occurred by the chemical reduction of NiO. This study highlights the concentration-dependent competitive relationship between chemical reduction and crystalline growth, and emphasizes the need for further investigation into the shape/contact-dependent chemical reactivity between RGO and NiO, as well as the thermodynamic size-dependent driving force for crystalline growth of individual RGO and NiO crystals.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.

Summary: This study focuses on the corrosion characteristics of AA 7075 and AA 7075 based hybrid composite fabricated using stir casting and hot rolling techniques. The results show that the hybrid composite produced by hot cross rolling exhibits better corrosion resistance compared to the base metal. The addition of a small amount of graphite improves the bonding between the matrix and reinforcements, and the hot cross rolling enhances this bonding, leading to the formation of a strong passivation oxide layer and increased charge transfer resistance, thereby improving corrosion resistance.
