Summary: Direct laser writing (DLW) is used to selectively create nitridized and carbonized features on a single mesoporous porous silicon (PS) film. Nitridized or carbonized features are formed in an ambient of nitrogen and propane gas, respectively, using a 405 nm laser. The range of laser fluence required to create different feature sizes without damaging the PS film is identified. This work demonstrates the potential applications of engineered PS films, such as selectively engineering thermal conductivity and electrical resistivity using carbonized PS, and micromachining and selective modification of refractive index using nitridized PS.

Summary: This work presents investigations into porous silicon thermo-resistive type thermal sensors and their advantages in speed-sensitivity trade-off compared to other similar thermal materials. Porous silicon films were suspended above a silicon substrate and their thermal properties were analyzed using the 3w method. The measurements showed isotropic thermal conductivity and thermal diffusivity for different porosity levels of the films. Finite element modeling using these thermal properties suggested that a thermal time constant of 5 ms could be achieved with significant improvement in overall speed-sensitivity trade-off.

Summary: Semiconductor nanocrystals known as quantum dots (QDs) have potential applications in biomedicine, but their potential hazardous effects need to be systematically analyzed for safe use. This study analyzed water-soluble core/shell QDs and found that the smallest QDs had the highest cytotoxicity. The surface charge of the QDs also affected cytotoxicity, with negatively charged QDs being more toxic and positively charged QDs being less toxic. The chemical composition of the QD core, however, did not noticeably affect cytotoxicity. This study provides important insights for understanding and improving the design of QDs.

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.
