The nuclear resonant scattering based on the Mössbauer effect in iron has proven to be an important spectroscopic method to address the most advanced scientific issues of physics and chemistry, as well as of material sciences, and is indispensable in Earth and planetary sciences. Synchrotron Mössbauer Source (SMS) spectroscopy1 is the ultimate method to characterize the electronic...
The advent of the first X-ray free-electron lasers (XFELs), FLASH in 2004 and LCLS in 2009, may prove to be the most profound development since the invention of the laser and, equally, the synchrotron. Sharp improvements in a number of laser parameters, most notably intensity and pulse duration, support this expectation. This brings scientific dreams within reach. Indeed, the unprecedented...
Here we present the new experimental stations devoted to the studies of matter under extreme conditions at the X-ray diffraction beamline ID15b and the X-ray absorption beamlines BM23 and ID24-DCM that were recently refurbished within the ESRF – Extremely Brilliant Source (EBS) upgrade program. In comparison with the stations before the EBS upgrade, they exhibit outstanding performances in...
The Aster-15 LVP can routinely generate high pressure (ca. 35 GPa) and temperature (ca. 3000 K) environments on samples for investigations using energy-dispersive X-ray diffraction (ED-XRD) and radiography in the high-energy range 30 – 160 KeV at the Wiggler beamline station P61B. Specialised assemblies may generate even higher pressures. The station provides two highly positional Ge-detectors...
Two end-stations based on large volume presses (LVP) have been built at SSRF, equipped with 200-ton and 2000-ton large volume presses respectively. These stations officially open to users in January 2024. The 2000-ton press adopts a dual-module design, supporting both Kawai and DDIA modules, and has achieved a pressure of 40GPa. The 200-ton press uses DDIA module. Both experimental stations...
The microstructure of nanoparticles, which is closely related to their size-tailored mechanical properties, has driven intensive investigations in the past decades [1-5]. It is recognized that the mechanical properties of nanoparticles may differ significantly from those of their bulk counterparts [2,3]. However, despite extensive studies, the origin of different mechanical behaviours as a...
The research exploring the limits of thermodynamical parameters, such as pressure, temperature, and magnetic field, is a fast-growing and fascinating discipline of science and technology that unravel many truths and facts of nature, which are not possible in ambient conditions. However, improving the quality of the experimental data obtained at extreme thermodynamical remains challenging. To...
