Summary: Polymer self-lubricating composite coatings are widely used to extend the life of machinery by controlling friction and wear. This study fabricated an epoxy nanocomposite coating with the addition of hexagonal boron nitride nanosheets (BNNSs)/CeO2 nanohybrid for enhanced anti-friction and wear resistance. The tribological behaviors of the coatings were investigated using a ball-on-disc friction tester, and the best friction and wear reduction properties were achieved with the content of BNNSs/CeO2 at 0.5 wt%. The enhancing mechanisms of BNNSs/CeO2 were discussed as well.

Summary: In this study, experimental evidence is presented to show that the monolayer h-BN insertion only partially blocks the interlayer carrier transfer, weakening the interlayer coupling effect. This explains the fascinating optoelectronic responses of graphene/h-BN/MoS2 devices. Additionally, the excitonic binding energies of graphene/h-BN/MoS2 are redshifted compared to graphene/MoS2, indicating the modulation effects of the h-BN barrier layer.

Summary: Obtaining highly stable 1T-MoS2 is crucial for studying the hydrogen evolution reaction (HER). However, it is currently challenging to prepare pure and stable 1T-MoS2. In this study, highly stable MoS2 with different 1T content was synthesized using a magneto-hydrothermal method. Pure 1T-MoS2 showed the best HER performance, and further modification with Ru nanoparticles improved the electrocatalytic HER activity. Theoretical analysis based on density functional theory confirmed the efficiency of 1T-MoS2 as an HER catalyst.

Summary: This study fabricates polyetherimide (PEI) matrix composite films with field-dependent nonlinear conductive behavior using MoS2 as filler. The MoS2 filled PEI composite film exhibits a nonlinear coefficient of 6.92 at a filler content of 15 phr, which is the percolation threshold. The nonlinear conductive behavior of the MoS2/PEI composites is driven by tunneling effect. The inclusion of MoS2 fillers enhances the dielectric constant of PEI.

Summary: In this study, vanadium carbide (V(2C)Tx) MXene was successfully synthesized and treated with an ammonia solution under different pressures using a hydrothermal process. The results show that the morphology of V(2)CTx MXene changed from uneven multilayered micrometre-size sheets to uniform few-layered nanometer-size sheets as the pressure increased. The optical and electronic properties were influenced by nitrogen-related defects, quantum confinement, and induced lattice strain due to the post-ammonia treatment.

Summary: Two Schiff base complexes, [CuL2] (Cu-Sal) and [CoL3] (Co-Sal), were synthesized and characterized. Crystal structure analysis showed a square planar geometry around Cu(ii) and various intermolecular non-covalent interactions in Cu-Sal. Both complexes were used as sensitizers in TiO2 based dye sensitized solar cells (DSSCs), and Co-Sal exhibited better photovoltaic performance than Cu-Sal due to improved light absorption and dye loading.
