Summary: Synthesizing ultrathin polyamide nanofilms through glycerol-regulated interfacial polymerization (IP) at the hexane-water/glycerol interface enables large-scale synthesis, defect-free transfer, and seamless compositing. The nanofilms exhibit ultrafast and robust nanofiltration performance when integrated using a facile and universal transfer printing method. The resulting sub-5 nm polyamide composite membrane demonstrates extraordinary water permeance and salt rejection, making it highly promising for practical separation scenarios.

Summary: This study reports an observation of more than an order of magnitude increase in saturation magnetization in BiFeO3/Ag nanocomposites at room temperature compared to bare BiFeO3 nanoparticles. The specific self-assembly pattern of BiFeO3 and Ag nanoparticles, as well as the charge transfer between Ag and O, are found to be responsible for this significant rise in room-temperature magnetization. The findings have implications for various applications, including biomedical uses.

Summary: This study describes a geochemistry-inspired method for synthesizing sub-5 nm nanodiamonds with sub-nanometer size deviation. By subjecting uniform iron carbide nanoparticles embedded in iron oxide matrices to high-pressure-high-temperature treatment, tunable nanodiamonds with diameters down to 2.13 and 0.22 nm standard deviation can be obtained. A self-limiting, redox-driven, and diffusion-controlled solid-state reaction mechanism is proposed, supported by in situ X-ray diffraction, ex situ characterizations, and computational modeling. This provides a unique approach for precisely controlling nanostructured diamonds under extreme conditions and lays the foundation for their full potential in emerging technologies.

Summary: In this study, an ab initio quantum transport approach was used to simulate sub-5 nm gate-length double-gate monolayer selenene FETs. The research found that 3 nm gate-length p-type ML selenene FETs, when considering negative-capacitance technology and underlap, can meet the 2013 ITRS standards for high-performance applications. Therefore, selenene has the potential to scale Moore's law down to a gate length of 3 nm.

Summary: Nano-optomechanical systems with gigahertz acoustic vibration are essential for all-optical manipulation, quantum control, on-chip data processing, and optomechanical sensing. In this study, a high-quality 5 GHz optoacoustic vibration and ultrafast optomechanical all-optical manipulation were demonstrated in a sub-5 nm tip-supported nano-optomechanical metasurface (TSNOMS). The design of a semi-suspended metasurface enhances the optical energy input and reduces mechanical and thermal losses, resulting in improved conversion efficiency and oscillation quality.

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.
