The upgrade of the Advanced Photon Source (APS) was recently completed reducing the natural emittance of the APS storage ring from 3000 to 42 pm. This reduction greatly increases the coherent x-ray fraction at high energies providing unique opportunities for interrogating materials at nanometer length-scales with lens-less imaging techniques or exploring the dynamics of systems...
SPring-8 was inaugurated in 1997 as a large-scale 3rd generation synchrotron radiation (SR) facility, and has served a wide range of academic and industrial users for decades. However, the demand for advanced X-ray analysis has grown significantly, far exceeding the capabilities of the current facility. Furthermore, aging and loss of competitivity have become serious concerns. To achieve both...
When discussing synchrotron phase-contrast imaging, the typical sample size is on the millimetre scale, and in a few cases, centimetres. Since 2000, the ESRF has made significant efforts to continuously increase the maximum size of samples that can be imaged.
In late 2018, the ESRF shut down to install the first high-energy fourth-generation storage ring: the Extremely Brilliant Source (EBS)....
Lithium-ion batteries (LIBs) are at the forefront of energy storage innovation, playing a crucial role in electrification and climate change mitigation. The electrochemical performance of LIBs is governed by the intricate movement of lithium ions across multiple length scales—from atomic-scale lattice structures to microscale porous electrodes and full-cell architectures. Each electrode...
The new APS-U beamline S-25 is set to revolutionize advanced spectroscopies by utilizing the APS upgrade, which provides brighter beams with reduced divergence. This enhancement will significantly improve X-ray collection capabilities through our 100mm and 300mm KB mirror systems, facilitating advanced spectroscopy and imaging. In addition to conducting X-ray absorption measurements on dilute...
PROTEOLYSIS1 (PRT1), an N-recognin of Arabidopsis thaliana, has a specificity for recognizing the N-terminal aromatic hydrophobic residue (Tyr/Phe/Trp) of its substrates, subsequently degrading them through ubiquitylation. Here, I represent the complex structures of the ZZ domain of A. thaliana PRT1 (PRT1ZZ) with bulky hydrophobic N-degron peptides. Unlike other ZZ domains, the binding site of...
Serial macromolecular crystallography (SMX) has become a powerful method for resolving
the structures of biological macromolecules at room temperature (RT). Although microfocus
beamlines at third-generation synchrotrons are instrumental, their data acquisition is typically
limited to the millisecond scale due to constraints in photon flux and detector speed. The
newly developed ID29...
The emergence of ambient pressure XPS (AP-XPS) clearly put a new road map on the world of surface science. The combination of differential pumps and electrostatic lens system enables the operation of XPS measurements possible under elevated pressure condition, even at the pressure of 1 Bar and beyond. Since its first demonstration at ALS in 2001, the community of AP-XPS rapidly grew and all...
The Coherent Application Beamline P10 at PETRA III is dedicated for coherent X-ray scattering and imaging experiments. P10 with two experimental hutches offers various experimental setups specialized for X-ray photon correlation spectroscopy (XPCS), Bragg CDI and holo-tomography (HT). The new Coherent Application Beamline (CAB) is planned for future 4th generation synchrotron radiation source...
The emergence of enhanced transverse coherence in X-rays has significantly expanded their applicability to structural investigations beyond well-ordered systems. When coherent X-rays scatter from disordered or random specimens, they produce characteristic speckle patterns in the diffraction images. These speckles encode rich information about structural disorder and fluctuations. By utilizing...
