Summary: MXenes are an interesting family of 2D materials with potential applications. Xray photoelectron spectroscopy (XPS) is a useful tool for understanding their nature. However, inconsistent curve fitting approaches and assumptions in previous studies have led to contrasting conclusions. This study presents realistic curve fittings using a first principles thinking strategy, providing a model for future XPS analysis of MXenes.

Summary: In this study, we explore the sensitivity of several core-level spectroscopic methods to the atomistic structure using water molecule as a test system. We define a metric to measure the magnitude of spectral change as a function of structure, which enables us to identify structural regions with high spectral sensitivity. By employing machine-learning emulator-based decomposition of structural parameter space, we are able to recover more spectral variance and identify spectroscopically dominant degrees of freedom.

Summary: Through simulation and experimental verification of XPS and Raman spectra of zigzag NBs, armchair NBs, and NHs, it was found that they have significant differences in spectral characteristics, so NBs and NHs can be distinguished using XPS and Raman spectroscopy.

Summary: Transition-edge sensors (TESs) are capable of highly accurate single particle energy measurement and have potential applications in photon detection fields such as astronomy. Compared to existing electron spectrometers, TESs do not require energy filtering, which can improve measurement rate significantly. Through simulations, it is found that TESs have comparable or better resolution in high count rate applications.

Summary: This paper explores the satellites of the Ti 1s and 2p core level spectra of SrTiO3 and TiO2 using hard x-ray PES. The theoretical analysis emphasizes the importance of higher-order Ti-O charge-transfer processes and provides a robust prescription for using the computationally cheap cluster model in fitting analyses of core level spectra.

Summary: This present work focuses on using two-dimensional correlation spectroscopy (2D-COS) to analyze X-ray photoelectron spectroscopic (XPS) data, and to obtain qualitative information about the underlying physics and chemistry of the studied process. The effects of the probing incident X-ray beam on the measured samples are also explored.

Summary: XPS analysis of layered clay systems with intercalated inorganic and organic compounds reveals valuable insights into the structure, coordination, and oxidative transformations of these compounds. By studying the shifts in binding energies and multiplet splitting, XPS can track changes in oxidation states and coordination environments within the materials.

Summary: Polyethylene terephthalate (PET) is a widely used thermoplastic polyester in industry. Surface modification is required for printing and coating processes, and plasma treatment is commonly used to increase the hydrophilicity of PET films. This study used X-ray ptychography and scanning electron microscopy to investigate the effects of plasma treatment on the surface morphology of PET films. The results showed increased roughness and changes in morphology, as well as an increase in oxygen content and polarity without significant damage to the polymer.

Summary: In this study, we utilized the K-shell core-electron excitation/ionization process to investigate the electronic structure of the CA*M adduct and compared it with the extended structures of CA and M. The complementary information on the heteromolecular CA*M system was obtained through N 1s X-Ray Photoelectron spectroscopy (XPS) and N K-shell Near Edge X-Ray Absorption Fine-Structure (NEXAFS) spectroscopy.

Summary: This study investigates the effects of mechanical polishing, vibratory polishing, and high-temperature annealing on the surface finish and corrosion resistance of 316L stainless steel. Vibratory finishing enhances the resistance to corrosion-induced passivity breakdown, while high-temperature annealing enables the exposure of the bulk microstructure. The results provide insight into surface enrichment engineering for enhancing the passivity of stainless steel.

Summary: In this study, a Bayesian analysis was conducted on the maximum mass of neutron stars with a quark core, revealing the most probable values of the hybrid star maximum mass to be around 2.36 solar masses. The results are robust with respect to uncertainties in the hadronic EOS and have implications for astrophysical phenomena such as post-merger products of neutron star mergers and short gamma-ray bursts.

Summary: This study presents a novel method for the one-step synthesis of ultra-bright CNOs using fish scale waste through microwave pyrolysis in seconds. The obtained CNOs have a highly crystallized multiple-shelled core-state and well-functionalized surface, exhibiting visible photoluminescence, superior quantum yield, and excellent dispersibility.

Summary: A comprehensive spectroscopic study was conducted on MOCVD-grown AlN thin films on sapphire and 6H-SiC substrates. The results showed better crystalline quality for AlN films on 6H-SiC compared to those on Al2O3. The study also revealed significant influence of the substrate on surface roughness and crystal quality of the films.
