Summary: Molecular switching has become a key functionality in addressable materials and surfaces. However, the wide variation in interfaces studied, from single-molecule devices to two-dimensional self-assembled monolayers and thin films, poses challenges in their use and characterization. The low number density of molecules on modified interfaces and the complexity of characterizing molecular function further complicate the analysis. This review discusses the techniques and approaches used for characterizing molecular switches applied to interfaces and emphasizes the importance of understanding the limitations and quirks of specific techniques through the use of model compounds.

Summary: Emergent behavior at oxide interfaces has driven research in complex oxide films for the past 20 years. Advances in synthesis and X-ray photoelectron spectroscopy (XPS) studies have enabled the growth of interfaces with unique properties not found in bulk materials. The in situ integration of synthesis and spectroscopy has improved the growth process and accelerated scientific discovery, with techniques including determination of interfacial intermixing, valence band alignment, and interfacial charge transfer.

Summary: This paper presents a method to port Boolean set operations between 2D shapes to surfaces of any genus with any number of open boundaries. By combining shapes into sets of freely intersecting loops and computing arrangements directly on the surface, it supports operations more general than standard Booleans and resolves inconsistencies in arrangements. Through discretizing input shapes and independently resolving arrangements within each triangle of the mesh, it reconstructs boundaries and interiors of cells in vector format output.

Summary: This study investigates the difference in dielectric constant and viscosity of water at the interface of hydrophilic surfaces compared to their bulk values, and suggests that the deviation is not caused by the electric field and ion concentration. The anomalous behavior of aqueous interfacial layers is primarily attributed to the intrinsic ordering and orientation of the interfacial water layer.

Summary: Above-band-gap optical excitation generates terahertz pulses via electron-hole pairs, with heavily doped silicon emitting weaker THz radiation compared to lightly doped samples. In heavily doped p-type silicon, a polarity reversal of the THz electric field is observed, indicating an opposition between doping related and carrier induced surface electric fields. This polarity reversal is caused by competition between diffusion and drift current.

Summary: Phase sensitive and heterodyne-detected sum-frequency generation spectroscopy provides the ability to separate the nonlinear susceptibility into real and imaginary components. It also offers information about the absolute orientation of molecules at interfaces and produces a linear absorptive spectrum that can be easily decomposed into different spectral components. However, maintaining both phase accuracy and phase stability is still a challenge. In this study, a new experimental design incorporating a wedge pair is introduced to accurately control the timing between the local oscillator and the sample signal, resulting in high phase accuracy and long-term stability in a compact and flexible configuration.

Summary: Interfaces between minerals and water are crucial in various geochemical and industrial processes, with MgO serving as a valuable model system due to its simple cubic structure. Vibrational sum frequency generation (vSFG) spectroscopy and water contact angle (WCA) measurements on MgO single crystal surfaces reveal detailed molecular interactions between water molecules and hydroxylated MgO surfaces. Despite their hydrophilicity, MgO surfaces exhibit unique non-H-bonded OH stretching vibrations and interactions with water that are not fully captured by traditional WCA measurements.

Summary: This paper discusses the influence of increasing concentration of carbon black (CB) on the physical and mechanical properties of SBR/BR rubber blends. The partitioning of CB towards the BR phase is quantitatively determined and confirmed using dynamic mechanical analysis (DMA) and solid-state nuclear magnetic resonance spectroscopy (SS-NMR spectroscopy). The results show that increasing CB concentration increases its partitioning towards the BR phase, affecting the properties and dispersion characteristics of the material.

Summary: In this research, the hybrid reinforcements of silica with either graphite or graphene oxide in natural rubber were studied. The addition of GO/SiO2 with a 3:1 ratio showed a synergistic reinforcement effect, significantly improving both strength and modulus while maintaining decent strain at break levels. The experimental data correlated well with the Guth Gold model, suggesting that filler/matrix interactions primarily govern the mechanical properties. The calometric response of the nanocomposites at the glass transition was analyzed, and the 3:1 GO/SiO2 composition showed the highest glass transition temperature and the most efficient filler intercalation.
