Summary: In this study, a single-crystalline framework material (Ln-MOF) is reported, which exhibits compass-like magnetic alignment under low magnetic fields. This magnetic alignment is attributed to the strong macroscopic anisotropy of Ln-MOF, where the highly-ordered structure allows the sum of molecular anisotropy of Ln-ions according to crystal symmetry. In tetragonal Ln-MOFs, the alignment can be either parallel or perpendicular to the field, depending on the easiest axis of molecular anisotropy. Reversible switching between the two alignments is realized by removing and re-adsorbing solvent molecules in the framework. When the crystal symmetry is lowered in monoclinic Ln-MOFs, the alignments become even inclined (47°-66°) to the field. These fascinating properties of Ln-MOFs would encourage further explorations of framework materials containing paramagnetic centers.

Summary: Ru-PEI-L-lys was immobilized on ZIF-8 to form Ru-PEI-L-lys-ZIF-8, which was then mixed with PtNPs to enhance the ECL response. The combination of selective aptamer and RecJf exonuclease in the system resulted in a highly sensitive ECL biosensor for thrombin detection, with a linear response range from 1 fM to 10 pM and a detection limit of 0.02 aM. This work presents a new strategy for designing stable ECL indicators and developing sensitive ECL sensors for biological analysis.

Summary: This study reports two types of stilbene-based metal-organic framework (MOF) films for photopatterning. The 2D Zn-2(sdc)(2) MOF film shows excellent photosensitive properties with a short photoconversion time, while the 3D MOF Zn4O(sdc)(6) film does not have this property. Furthermore, the Zn-2(sdc)(2) film exhibits reversible fluorescent photoswitch behavior and can achieve high-efficiency, erasable photopatterning with various sizes. This research not only develops a new type of photosensitive crystalline network film, but also provides solutions for erasable photopatterning in optical applications from macroscopic to microscopic scales.

Summary: In this study, we investigated the charge carrier dynamics in a graphitic carbon nitride/tungsten telluride van der Waals heterostructure using time domain density functional theory and nonadiabatic molecular dynamics simulation. The results revealed ultrafast electron and hole-transfer dynamics in the heterostructure, as well as a delayed electron-hole recombination process. Factors such as electron-phonon coupling, band gap, nonadiabatic coupling, and decoherence time were found to affect the charge carrier dynamics.

Summary: This study investigates the potential of Ti2CO2-WX2 (X = S, Se, Te) vdW heterostructures as Z-scheme photocatalysts. The Ti2CO-WSe2 heterostructure emerges as the most promising material, with longer electron and hole transfer timescales for efficient photocatalytic pathway. The study also reveals that the HER and OER processes occur spontaneously on the surface of the heterostructure without any co-catalyst, establishing it as a potential mediator-free direct Z-scheme photocatalyst for overall water splitting.

Summary: Using density functional theory and the Boltzmann transport equation, the electronic structure and thermoelectric behavior of two bulk bialkali antimonides, RbK2Sb and RbNa2Sb, were studied. The calculations showed that both antimonides have ultralow lattice thermal conductivities due to intrinsic phonon scattering. The thermodynamically, mechanically, dynamically, and thermally stable p-type RbK2Sb exhibited high values of Seebeck coefficient, while p-type RbNa2Sb exhibited a moderate Seebeck coefficient and optimum electrical conductivity. The estimated maximum values of figure of merit at 700K (300K) were 4.40 (1.91) and 5.84 (2.76) for p-type RbK2Sb and RbNa2Sb, respectively.

Summary: In recent years, there has been a focus on using metal-organic frameworks (MOFs) to activate C-H bonds of light alkanes. The energy-demanding steps in the catalytic pathway are the formation of metaloxo species and the subsequent cleavage of C-H bonds. By employing density functional theory, we have found that heavier congeners in a specific group of MOF-525(M) have higher exothermic oxo-formation enthalpies ΔHO and lower N2O activation barriers. It has been concluded that MOF-525(Ru) and MOF-525(Ir) can be effective catalysts for methane hydroxylation based on independent analyses of activation barriers and structure-activity relationship. ΔHO can serve as a guide in selecting the optimum catalyst for methane hydroxylation from a large set of available systems.

Summary: In this study, the charge carrier dynamics in van der Waals heterostructures made of 2D SnX2-supported ZrS(2), ZrSe2, and ZrSSe monolayers are investigated using time domain density functional and non-adiabatic molecular dynamics simulation. The results show that switching from AB to AA stacking extends the carrier lifespan significantly due to weak electron-phonon coupling, lower non-adiabatic coupling, and fast decoherence time. This study reveals that stacking pattern variation is an effective tool for developing efficient photovoltaic devices based on 2D van der Waals heterostructures.

Summary: It has been predicted that unsupported and oxygen deficient TiO2 surface supported Ru-x/Rh-x nanoclusters can efficiently and selectively convert CO2 into formic acid (FA). The catalyst performance is enhanced by decreasing the size of the metal cluster on the oxide support. Under ambient conditions, a dual atom Rh-2 site catalyst is found to be a better CO2 hydrogenation catalyst. The production rate of FA becomes faster over a supported Ru-4 catalyst at temperatures above 500 K.

Summary: Hollow MoS2 cubes and spheres were successfully synthesized using a one-step hydrothermal method with the hard template method. The hollow MoS2 cubes exhibited higher specific capacitance and energy density compared to the hollow MoS2 spheres. The symmetrical supercapacitors assembled with these hollow structures showed good performance and high capacity retention after multiple cycles. These findings suggest that controlling the pore structure and surface characteristics of MoS2 is crucial for enhancing its electrochemical properties.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Summary: The stability of La1/3Sr2/3Fe1-xMnxO3-delta, a perovskite-type oxide, under reducing conditions is dependent on the manganese content. Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions. Additionally, the change in the La/Sr ratio affects the concentration of iron and manganese ions.
