Summary: MXenes, a newly discovered class of two-dimensional materials, show promising potential for biomedical and electronic applications. First-principles calculations on the titanium carbide MXene surface reveal physisorption as the dominant mechanism for nucleobases, with molecules sitting parallel to the surface at a distance of about 2.5A. The moderate adsorption energies and van der Waals interactions suggest the Ti2CO2 MXene's suitability as a nucleobase sensor.

Summary: In this study, hierarchical 2D-Bi2MoO6@2D-MXene nanohybrid was successfully fabricated by growing Bi2MoO6 nanosheets on the surface of MXene nanosheets, which suppressed the agglomeration of Bi2MoO6 and maximized the exposed activity sites. The Schottky heterojunction derived from MXene not only promoted photoinduced electron transport but also limited photoexcited electron-hole recombination, leading to enhanced visible-light photocatalytic water oxidation activity.

Summary: In this study, the structural and electronic properties of polar GaN/MoSSe heterostructures were investigated using first-principles calculations. It was found that a self-doped p-n junction can be achieved by modifying the band alignment, leading to high carrier concentrations. This behavior can be attributed to charge redistribution and the intrinsic electric field induced by polarization, causing shifts in the band edge positions and the induction of the quantum Stark effect.

Summary: Based on first-principles density functional theory, this study investigated the structural and electronic properties, as well as the hydrogen evolution reaction (HER) activity, of heterostructures composed of different MXene and N-doped graphene (NDG). The results showed significant electron transfer at the interfaces of the heterostructure, and the addition of MXene modified the electronic structure of the NDG surface. Furthermore, the heterostructure enhanced the adsorption of H on the NDG surface and improved HER activity. The effects of heterostructure types and H coverage rate on HER activity were also investigated. This study suggests that appropriately designed MXene/NDG heterostructures have the potential to be HER catalysts.

Summary: This paper presents a theoretical study on the thermoelectric properties of X3N2O2 (X = Hf, Zr) MXene monolayers, considering electron-phonon coupling. The X3N2O2 MXene monolayers exhibit homogeneous electron and phonon transport properties. The Hf3N2O2 monolayer shows better n-type electron transport properties and higher power factor compared to the Zr3N2O2 monolayer. The lattice thermal conductivity is higher in the Zr3N2O2 monolayer due to larger phonon group velocity. The Hf3N2O2 monolayer is found to be more suitable for thermoelectric materials with higher thermoelectric figure of merit (ZT) values.

Summary: The effects of strain on the adsorption of CO, O2, SO2, and H2O molecules on Ni-SG were investigated using first principles calculations. It was found that compressive strain increases the adsorption energies of all molecules, while tensile strain preferentially adsorbs CO and O2 molecules. Furthermore, tensile strain facilitates the LH mechanism and hinders the ER mechanism on Ni-SG. Overall, tensile strain enhances the sulfur and water resistance of Ni-SG and promotes CO oxidation reactions.

Summary: In this study, the nitrogen reduction activity of transition metal decorated bismuthene TM@Bis was fully investigated using density functional theory calculations. It was found that W@Bis exhibited the highest efficiency, with the potential-determining step located at the last protonation step of *NH2 + H++ e- -> *NH3 via the distal mechanism, with a limiting potential (UL) of 0.26 V. Additionally, the dopants Re and Os showed promise as experimental synthesis candidates despite slightly higher UL values of 0.55 V for NRR. The candidates Ti, V, Nb, and Mo had relatively lower UL values of 0.35, 0.37, 0.41, and 0.43 V but may be affected by the side hydrogen evolution reaction. Interestingly, a volcano curve was established between UL and valence electrons of metal elements, with W located at the summit due to the underlying acceptance-back donation mechanism. Therefore, this work provides a fundamental understanding for the design of materials for nitrogen reduction electrocatalysis.

Summary: In this study, we conducted a detailed investigation of the band structure, optical absorption spectrum, carrier mobility, and exciton binding energy of 2D all-inorganic double perovskite Cs3AgBiBr7. The results showed that Cs3AgBiBr7 has an indirect band gap, low carrier mobility, high exciton binding energy, and significant light absorption in the UV region. We also found that Cs3AgBiBr7 may be a potential exciton insulation candidate and more suitable for luminescence than photovoltaic devices. We hope our theoretical results will inspire and promote the experimental exploration of 2D all-inorganic double perovskite materials for photoelectric applications.

Summary: In this study, a novel LED-activated periodate advanced oxidation process (UVA-LED/PI AOP) was developed and investigated for the degradation of naproxen (NPX) and other micropollutants. The UVA-LED/PI AOP showed a broad-spectrum degradation ability, with hydroxyl radical and ozone being the dominant species responsible for NPX degradation. The pH and irradiation wavelength had a negative effect on NPX degradation, explained by the decreased quantum yield of PI. The UVA-LED/PI AOP could be a promising technology for micropollutant treatment in aqueous solutions.

Summary: In this paper, a Metal-Dielectric-Metal (MDM) type nanocavity structure is proposed, which utilizes silver nanorings as the top layer, UCNPs as the dielectric layer, and silver mirrors as the bottom layer. Efficient absorption peaks are generated at wavelengths of 808 nm, 980 nm, and 1530 nm, producing strong local fields for excitation light. Numerical simulations yield fluorescence enhancement factors of approximately 7.03 x 105, 3.02 x 105, and 6.18 x 104 at wavelengths of 808 nm, 980 nm, and 1530 nm, respectively. This design offers a new way to enhance the efficiency of up-conversion luminescence and improves the performance of applications such as biosensors and filters.

Summary: Nanoscale fluorescence thermometry based on upconversion nanoparticles (UCNPs) with active shell shows high sensitivity in water. The fluorescence intensity ratio of Tm3+ at 475 nm (1G4 -> 3H6) and 450 nm (1D2 -> 3F4) is used to determine the temperature. The active core/active shell nanoparticles exhibit a thermometry sensitivity of 0.048/K in aqueous environment, which is 400% higher than that in the environment without water molecules. This enhanced sensitivity is attributed to selective quenching of the 450 nm emission band by water and the separated quenching and emission processes in the active core/active shell structure.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
