Summary: A bis-stabilized interface strategy was developed to prepare high-performance low-dielectric benzocyclobutene (BCB)-based nanocomposites using a rational-designed and facile synthesized difunctional silane modifier. Hollow silica nanoparticles (HSNs) were efficiently surface-modified with the difunctional silane and chemically cross-linked with the BCB resin matrix, resulting in HSNs-doped organic-inorganic nanocomposites. The dielectric properties of the nanocomposites were adjusted by changing the doping ratios and cavity diameters of HSNs. The resultant 0.25 wt % HSNs-doped nanocomposites with a cavity diameter of 180 nm exhibited a significantly reduced dielectric constant of 2.12 by 20% compared to commercial BCB resin, while maintaining low dielectric loss, excellent thermal stability, and hydrophobicity. This study provides a simple and universal strategy for fabricating low-dielectric BCB nanocomposites for future high-density advanced packaging applications.

Summary: A polarization-independent, all-optically modulated multiband metamaterial coherent perfect absorber (CPA) is proposed, which can be controlled by changing the phase difference of two incident light beams. The absorber can be modulated at telecommunication wavelengths, allowing for simultaneous modulation at 1310 nm and 1550 nm. Switchable logical gate states can also be achieved. The absorber utilizes bound states in the continuum (BIC) mode to realize another absorption band, expanding its application range and flexibility. The results suggest promising applications in optical switches, smart multi-band absorbers, and telecom devices.

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.

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.
