Summary: Environmental transmission electron microscopy is used to study the growth of Au nanoparticle seeded GaSb nanowires in situ. It is found that the precursor V/III ratio affects the morphology, composition, and diameter of the nanowires. The observed trends can be reproduced in a conventional exsitu system, highlighting the transferability and importance of the results obtained in situ.

Summary: Photomagnetic-chiral anisotropy (PM-ChAC-E) and surface-enhanced Raman scattering chiral anisotropy (SERS-ChAC-E) are novel enantiomeric discrimination techniques based on the chiroptical response between chiral nanostructured metal films (C) and enantiomers (E). The discrimination mechanism of chiral nanostructured Au films (CNAFs) is explained through the spin polarization coupling (SPC) between the enantiomers and CNAFs. The findings provide a possible mechanism based on spin selectivity in chiral structures and offer a universal theory for enantiomeric discrimination.

Summary: In this study, we investigated the detection of cytochrome c (cyt c) adsorbed on lipid films or covalently bonded to 11-mercapto-1-undecanoic acid (MUA) on a gold layer using quartz crystal microbalance with dissipation monitoring (QCM-D). We found that a stable cyt c layer can be formed on a negatively charged lipid film, but addition of DNA aptamers specific to cyt c led to its removal from the surface. Cyt c covalently bound to MUA also provided a stable protein layer, and the addition of DNA aptamers modified with gold nanowires resulted in changes in resonant frequency.

Summary: This study introduces a novel fabrication concept based on shadow walls, enabling in situ, selective, and consecutive depositions of superconductors and normal metals to form defect-free semiconducting-superconducting interfaces. The method allows for the realization of devices in a single shot, eliminating fabrication steps after the synthesis of the fragile semiconductor/superconductor interface. The cleanliness of the technique enables systematic studies of topological superconductivity in nanowires and the synthesis of advanced nano-devices based on a wide range of material combinations and geometries while maintaining high interface quality.

Summary: Lattice distortions and defects have a significant impact on the electronic structure and chemical adsorption of noble metal surfaces. Introducing defects is an effective strategy for enhancing the activity of noble metal catalysts. In this study, a fusion approach is developed to fine-tune defects and lattice strain in Au-Pd nanowires. The intermediate Au-Pd NW60 nanowire exhibits excellent catalytic activity and stability in the oxygen reduction reaction, surpassing commercial Pt/C in terms of half-wave potential and specific activity.

Summary: This study successfully fabricated a lightweight composite phase change material (PCM) without liquid phase leakage, addressing the requirements for high enthalpy and solar-thermal energy conversion and storage. By utilizing a combination of melamine foam (MF), graphene nanoplatelets (GNP), and carbon nanotubes (CNT) as the supporting framework, along with octadecane as the core PCM, the composite PCMs with an 85.8% loading amount exhibited comparable phase transition enthalpy to that of pure octadecane. Furthermore, the composites showed minimal alterations in thermal performance after 350 simulated hot and cold cycles, and exhibited exceptional abilities in solar-thermal conversion and electrothermal conversion, with a photothermal conversion efficiency exceeding 95%. Consequently, the developed composite PCMs demonstrate significant potential for applications in thermal energy storage and conversion.
