Excitation signatures of isochorically heated electrons in solids at finite wave number explored from first principles [PDF]

Physical Review Research
Ultrafast heating of solids with modern x-ray free electron lasers (XFELs) leads to a unique set of conditions characterized by the simultaneous presence of heated electrons in a cold ionic lattice.

Ultracompact 3D microfluidics for time-resolved structural biology

Nature Communications, 2020
To advance microfluidic integration, we present the use of two-photon additive manufacturing to fold 2D channel layouts into compact free-form 3D fluidic circuits with nanometer precision.

Dispersion‐compensated Rowland spectrometer: implications for uranium VB‐RIXS

Journal of Synchrotron Radiation, Volume 33, Issue 1, Page 218-226, January 2026.
A valence‐band resonant inelastic X‐ray scattering instrument, operating in the tender X‐ray range, uses an incoming beam with a linear energy dispersion to reach the intrinsic resolution of the Rowland spectrometer. Such a scheme is insensitive to the incident bandwidth and therefore preserves count‐rates despite the higher resolution.The total energy

Femtosecond X-ray cross-correlation analysis of disordered crystals forming in a supercooled atomic liquid

IUCrJ
We demonstrate an advanced scattering method for accessing the 3D reciprocal space of crystalline structures forming in a rapidly supercooled noble-gas liquid using a combination of femtosecond X-ray diffraction and X-ray cross-correlation analysis.

Roadmap of ultrafast x-ray atomic and molecular physics

, 2018
X-ray free-electron lasers (XFELs) and table-top sources of x-rays based upon high harmonic generation (HHG) have revolutionized the field of ultrafast x-ray atomic and molecular physics, largely due to an explosive growth in capabilities in the past ...

Strategies for mitigating radiation damage and improving data completeness in 3D electron diffraction of protein crystals

Acta Crystallographica Section D, Volume 82, Issue 1, Page 11-22, January 2026.
This work demonstrates that multi‐position data acquisition mitigates radiation damage in electron diffraction of three‐dimensional protein crystals and that merging data from selected crystals in distinct orientations enhances completeness. Application of the two approaches enables high‐quality structural models to be obtained from limited or ...
