Summary: Fluorescent probes are valuable tools for visualizing plasma membranes and their related physiological processes in a spatiotemporal manner. However, there is a lack of probes for long-term imaging of plant cell membranes. In this study, we designed an AIE-active probe with NIR emission that allows for four-dimensional spatiotemporal imaging of plant cell membranes. The probe showed excellent specificity and long imaging times, making it a valuable tool for monitoring dynamic processes of plasma membrane-related events.

Summary: Constructing charge transfer systems and altering the packing arrangement are effective methods for controlling the efficiency of nonlinear optical materials. This study investigates the impact of solvent and solid environments on the static first hyperpolarizabilities of TSCT and model compounds. Results show that the solvent effect increases the hyperpolarizabilities, and different packing modes and intermolecular interactions significantly influence the second-order NLO properties.

Summary: This study investigated copper nanostructuring through anodizing, resulting in the formation of nanowires composed of Cu2O, CuO, Cu(OH)2, and malachite Cu2CO3(OH)2 within a certain voltage range. The diameter of the nanowires depended on the applied voltage. Oscillations in current density at higher voltages indicated partial delamination of the oxidized layer with subsequent self-healing.

Summary: A series of coil-rod-coil molecules with a 9,10-distyrylanthracene (DSA) core were synthesized, containing flexible parts made of different polyethylene oxide chains. These molecules exhibited aggregation-induced luminescence and could form charge-transfer complexes with specific small molecules. Interestingly, the DSA structure could undergo photolysis under ultraviolet light, causing the disappearance of luminescence and making these molecules potential for photodegradable applications. Additionally, they could be utilized as organic dyes for information encryption and anti-counterfeiting purposes.

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.
