Summary: In this study, a method for retrieving the size and composition of noble metal Ag-Au alloy nanoparticles simultaneously is introduced. The method utilizes an analytical ultracentrifuge equipped with a multiwavelength extinction detector to measure the optical and sedimentation properties of the particles. The presented approach provides a simple and fast way to determine noble metal alloy nanoparticle size and composition distributions, contributing to improved synthesis and scale-up of particulate systems.

Summary: Ptychography is a high-resolution diffraction imaging technique that is sensitive to experimental variations. High-speed data acquisition with short exposure can minimize the impact of experimental variations, and continuous multi-pass scan via high-speed ptychography can achieve high-resolution imaging. This low-dose scan strategy is important for radiation-sensitive sample studies and time-resolved imaging.

Summary: This study presents a theoretical exploration of surface step characterization using reflected incoherent-light differential interference microscopy, with consideration of the optical diffraction effect. By integrating localization analysis, a quantitative differential interference optical system is developed, which demonstrates high axial resolution in measuring surface height variation. The experiment successfully characterizes nanometer-size steps with subnanometer accuracy, indicating the potential of optical differential interference microscopy for real-time surface structure characterization in micro/nano-electromechanical systems.

Summary: Microlens arrays based on selective wetting offer a new approach for compact and miniaturized imaging and display with ultra-high resolution. However, current selective wetting lenses are limited by the lack of precise pattern for highly controllable wettability contrast, which hinders the practical high-performance microlens arrays.

Summary: The study developed an image super-resolution method for hard X-rays and successfully applied it to experimental coherent Bragg diffraction data. By analyzing individual photon locations in nearly-dark instances, fine fringe details of high-energy X-ray Bragg coherent diffraction patterns were resolved to a high upsampling factor. The method provides significant improvement in super-resolution and offers a metric for estimating the limit of reliable upsampling under specific experimental conditions.

Summary: we report a novel inelastic scanning confocal light detection and ranging (LiDAR) system for remote underwater volumetric imaging of fluorescent objects. The system combines a continuous wave excitation beam with a pinhole in a conjugated detection plane to reject out-of-focus scattering and accomplish near-diffraction limited probe volumes. By combining bi-directional scanning with remote focusing, three-dimensional data can be acquired. The system has been demonstrated to enable selective volumetric imaging of obstructed layers and in vivo autofluorescence imaging of aquatic fauna.

Summary: Chromatin is a densely packed DNA-protein complex in the cell nucleus, with nanoscale chromatin compaction playing critical roles in cell nuclear processes. Using DYNAMICS imaging allows for mapping chromatin organization in live cell nuclei, detecting and quantifying chromatin compaction level at nanoscale, and effectively observing chromatin condensation and decondensation processes. This label-free imaging technique offers the opportunity to investigate chromatin conformational dynamics and their significance in gene activities.
