Summary: This paper presents a colorimetric sensing system for rapid detection of gas-phase analytes from flowing micro-volume fluid samples. The sensor platform combines an analyte-responsive metal-insulator-metal (MIM) thin-film structure with a large area quartz micropillar array, allowing precise alignment and separation of optical and fluidic structures. The sensor's response time is reduced from minutes to seconds, making it suitable for portable/wearable devices. The platform shows potential for continuous, compact, and quantitative colorimetric analysis of volatile analytes in low-volume samples.

Summary: Using finite element calculations, this study investigates the near field properties of two types of commonly used metal nanostructures, namely the tip-substrate model and the nanoparticle-on-mirror configuration. The study systematically examines the spatial confinement, electric field enhancement, and fluorescence quantum efficiency of a model molecule in these structures. The results show that the tip-substrate model exhibits higher local electric field enhancement while the nanoparticle-on-mirror model provides more localized plasmon electric field. Both models significantly enhance non-radiative decay rates in the wavelength range of 500-1000 nm, with the tip-substrate model displaying better performance in radiative enhancements and emission quantum yield.

Summary: By studying the formation of multilayered self-scrolled yarns from twisted hyperelastic sheets, we found that these yarns can be reconfigured and redeployed through recursive folding and twist localization. We combined elasticity and origami to explain the observed ordered progression beyond traditional models and used Schlafli symbols to algorithmically generate the resulting structures. By introducing a geometric model, we explained the formation and structure of self-scrolled yarns. This study demonstrates that origami can help us understand the transformation of stretchable sheets into self-assembled architectures with a simple twist.

Summary: It has been demonstrated that the external quantum efficiency (EQE) of organic photovoltaic cells can be improved by photopolymerization between adjacent C-60 molecules in zinc phthalocyanine (ZnPc) and fullerene (C-60) bilayer films. The increase in the number of photogenerated intra- and inter-molecular excitons in photopolymerized C-60 film contributes towards enhancing the EQE in the 400-600 nm wavelength range.

Summary: The bandgap emission from GaN epilayer was enhanced by localized surface plasmon resonance (LSPR) in a quadrupole oscillation mode using Ag nanoparticles (NPs) fabricated on the GaN. The Ag NPs gradually changed shape over time and were eventually destroyed, leading to less effective results in previous studies. However, by using oxide thin films to protect the Ag NPs, enhanced photoluminescence of the GaN epilayer was obtained.

Summary: We demonstrate that the plasmonic properties of Au nanodisk structures can be enhanced by heat treatments, and the resonance wavelength can be tuned by temperature. With a Ni adhesion layer, the resonance peak increases and blue-shifts due to improved metal quality, while without the adhesion layer, the resonance wavelength can be tuned over a wider range by reducing the size of nanostructures through annealing. For Ag nanodisks with the adhesive layer, the plasmon resonance wavelength is blue-shifted due to size reduction through thermal annealing. Full-color tuning of plasmonic resonance is possible by controlling the diameter and height of Ag nanodisks under appropriate temperature conditions.

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.
