Summary: Studying chemical reactions in a natural environment-like setting provides important insights into dynamic oxidation processes. The use of Transmission Electron Microscopes (TEMs) and X-ray Nanoprobes allows for nanoscale chemical and structural information through imaging and spectroscopy. However, the design and implementation of in situ sample environments face challenges due to controlled operating conditions and constraints. This article outlines the setup of an in situ liquid sample environment for the Hard X-ray Nanoprobe beamline (I14) at Diamond Light Source, with the capability of imaging and spectroscopic analysis of samples exposed to liquid flow and heating up to 80 degrees Celsius. The design of the sample cell offers the potential of combining X-ray and electron microscopy for in situ multi-length scale imaging and spectroscopy of samples in liquid.

Summary: Doping metal ions into halide perovskite materials is a promising approach to enhance film stability and improve solar cell performance. Investigation into the incorporation of catalytically active transition metals Pt and Pd shows that doping can suppress phase segregation in the perovskite layer. This suggests the potential to obtain catalytically active halide perovskite films where the perovskite serves as a host matrix.

Summary: Understanding the local changes in optoelectronic properties in lead halide perovskites under light and electric field-induced effects is crucial for establishing a detailed structure-function relationship. In this study, we used single-molecule absorption scanning tunneling microscopy (SMA-STM) to investigate the nanoscale surface inhomogeneity of a mixed A-site cation/mixed halide perovskite under pulsed 532 nm photoexcitation, which provided insights into the variation of grain-to-grain absorption behavior and reduction in electronic bandgap under illumination. By combining synchrotron X-ray STM (SX-STM) and pump-probe time-resolved wide-angle X-ray scattering, we further correlated the observed changes in absorption signals with structural changes and demonstrated the presence of nonthermal lattice deformations upon photoexcitation.

Summary: In this study, the role of polarization on the surface structure and chemistry of a model ferroelectric BaTiO3 thin film was investigated using synchrotron X-ray scanning tunneling microscopy (SX-STM) and computational absorption spectroscopy. The results showed that polarization switching increased the X-ray absorption intensity and modulated the surface structures. Theoretical calculations supported these findings and provided evidence for the effect of polarization switching on the binding strength with molecular O2. This study advances the understanding of the surface chemistry and electronic structure of ferroelectrics, which can inform the design of interfaces with tailored properties.

Summary: Since the discovery of X-rays in 1895, their use has been widespread in various fields. In this study, X-rays were used to characterize the elemental and chemical state of a single atom. By using a specialized tip as a detector, the X-ray-excited currents from iron and terbium atoms coordinated to organic ligands were detected. This work connects synchrotron X-rays with a quantum tunnelling process, enabling future X-ray experiments for simultaneous characterizations of elemental and chemical properties of materials at the single-atom level.

Summary: Noninvasive X-ray imaging of nanoscale objects, such as integrated circuits, requires scanning methods like ptychography and tomography. In this study, Attentional Ptycho-Tomography (APT) is proposed as a machine learning-based approach to reduce scanning time and provide accurate reconstructions. Experimental results demonstrate that APT can significantly reduce data acquisition and computation time from 67.96 hours to 38 minutes while maintaining quality. This physics-assisted and attention-utilizing machine learning framework is expected to find applications in other branches of nanoscale imaging, including materials science and biological imaging.
