Summary: The sulfur vacancy defects in two-dimensional transition metal dichalcogenides have been shown to influence the dispersibility, aggregation, free radical generation, and dissolution of 2H phase molybdenum disulfide in aqueous solution. Protein corona formation with higher thiol group affinity was observed when S-vacant 2H-MoS2 interacted with proteins related to antioxidation, photosynthetic electron transport, and cytoskeleton structure of microalgae. These interactions resulted in aggravated algal growth inhibition, oxidative damage, and reduction in photosynthetic efficiency induced by 2H-MoS2. Our findings emphasize the importance of rational design for TMD application.

Summary: In this study, MoO3:MoS2 hybrid thin layers were synthesized through partial oxidation of MoS2 under darkness conditions. Liquid-phase exfoliation was used to achieve uniform MoS2 nanoflakes and high reproducibility of results. XPS analyses confirmed the presence of MoO3, MoS2, and MoOxSy in the hybrid layer, while optical absorbance showed redshifted absorption peaks and new peaks in the near-infrared region.

Summary: Decorating noble metal nanoparticles on 2D semiconductor material MoS2 can enhance selectivity for chemical sensor arrays. We successfully decorated noble metal nanoparticles on MoS2 flakes without reducing agents. The selectivity of MoS2 flakes changed significantly after surface decoration, allowing clear distinction between ammonia, hydrogen, and ethanol gases. The role of noble metal decoration in selectivity change was investigated using density functional theory calculations, which revealed that the sensitivity to hydrogen correlated with binding energy, while the sensitivity to ammonia was related to deactivation of binding sites at the MoS2 edge due to metal nanoparticle decoration. This study provides fundamental understanding for designing efficient sensor arrays based on 2D materials.

Summary: In this study, the magnetic properties of triangular silicene, silicon carbide, Si2BN, and their heterostructures were investigated through first principles calculations. It was found that hydrogenation of surface Si atoms significantly enhances the net spin of silicene, while attaching iron oxide transforms silicene into a paramagnetic material. Additionally, stacking and twisting in heterostructures play a role in controlling magnetic and electronic properties, making these flakes promising candidates for semiconductor spintronics.

Summary: Nowadays, there is a growing adoption of In Vitro Fertilization (IVF) techniques. A promising strategy is the use of non-physiological materials and naturally derived compounds for advanced sperm preparation methods. The study showed that MoS2/Catechin nanoflakes and catechin (CT) did not have any negative effects on sperm capacitation, while adding a specific concentration of CT increased the fertilizing ability of sperm in an IVF assay. These findings suggest that catechins and new materials obtained using natural or bio compounds could enhance current sperm capacitation strategies.

Summary: Imogolite nanotubes, known for their narrow diameter distribution and high curvature, have potential for advanced material fabrication. Current research focuses on surface functionalization and Si substitution on Ge, neglecting the doping of Al sublattice. Quantum-chemical calculations show the possibility of doping trivalent cations into the Al sublattice of imogolite, which may lead to the synthesis of chemically modified imogolite.

Summary: Two new high-pressure modifications of sodium yttrium germanate NaYGeO4 have been studied, with reversible pressure-induced phase transitions from olivine-type NaYGeO4 to new phases observed. A high-pressure polymorph of NaYGeO4 with NaNdSiO4 crystal structure was formed at 800 degrees C starting from 6 GPa, and another new high-pressure modification of NaYGeO4 with NaSmSiO4 crystal structure was found in small amount. In addition, a yet undescribed polymorph of Y2Ge2O7 with pyrochlore-type structure was isolated at 8 GPa and 800 degrees C.

Summary: This study investigates the evolution of mechanical properties of synthetic phyllosilicate nanoscrolls after a series of heat treatments. It is found that the Young's modulus and the contribution of shear deformation to the mechanical behavior of the nanoscrolls can be controlled through heat treatment. This is due to the heat-induced formation of covalent bonds between adjacent layers, complicating the shear deformation.

Summary: Pb1+хS thin films with a thickness of 190-360 nm were synthesized on glass substrates using different thioamides as sulfur precursors. The films exhibited polycrystalline structure and n-type conductivity. The sulfur origin was found to affect the crystalline structure, morphology, and formation mechanism of the Pb1+хS films. The excess of lead was correlated with the optical band gap, where a greater excess led to a wider band gap. Fractal analysis suggested a cluster-by-cluster association model for the film growth.
