Dynamics of valence-shell electrons and nuclei probed by strong-field holography and rescattering

Nature Communications, 2017
Capturing ultrafast molecular dynamics is difficult as the process involves coupled and very fast motions of electrons and nuclei. Here the authors study non-adiabatic dynamics in the NO molecule using strong-field photoelectron holography to shed light ...

Wavefront Modulation and Beam Shaping into Arbitrary Three-Dimensional Intensity Distributions

Photonics, 2021
In this study the methods of three-dimensional (3D) wavefront intensity modulation by employing contrast-inverted holography, previously introduced as Gabor inverted holography, are further investigated.

Hybrid Electron Holography [PDF]

Microscopy and Microanalysis, 2015
When a plane wave, whether a photon, electron or neutron, passes through a transparent object, the exit wave provides information about the object’s internal structure, refractive index, electric and magnetic fields within and near the specimen plus many other signals, depending on the type of radiation. The ability to detect the full exit wavefunction

Carbonated Fluorapatite‐Gelatin‐Composites: Morphogenesis and Structure of Kniep's Dumbbells

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Inspired by the pioneering work of Prof. Rüdiger Kniep on fluorapatite‐gelatin nanocomposites also known as “Kniep's Dumbbells,” this study investigates carbonated fluorapatite‐gelatin aggregates synthesized by the double diffusion technique within a gelatin gel.

Full‐field X‐ray fluorescence imaging using a Fresnel zone plate as a coded aperture: optimized reconstruction algorithm and first trial of hyperspectral XANES mapping

Journal of Synchrotron Radiation, EarlyView.
The full‐field X‐ray fluorescence imaging method, where a Fresnel zone plate is employed as a coded aperture, was tested for the first time at a beamline, and its corresponding reconstruction code was optimized. It was also employed to perform, also for the first time using full‐field and fluorescence modes, hyperspectral XANES mapping.This study ...

Tailoring electron vortex beams with customizable intensity patterns by electron diffraction holography

Opto-Electronic Advances
An electron vortex beam (EVB) carrying orbital angular momentum (OAM) plays a key role in a series of fundamental scientific researches, such as chiral energy-loss spectroscopy and magnetic dichroism spectroscopy.

Evidence of a local BCC‐type coordination of cobalt in FCC taenite of iron meteorites

Meteoritics &Planetary Science, EarlyView.
Abstract Ni, Co, and Fe K‐edge X‐ray absorption fine structure (XAFS) measurements were performed, revealing an unexpected local structure around Co in well‐known iron and stony‐iron meteorites. Cobalt is enriched in kamacite but remains in taenite at concentrations of at least 0.3 atom%.

Dynamic Holographic Display With Multiplexed Dielectric Metasurfaces

Nanophotonics, Volume 15, Issue 12, 25 June 2026.
Based on multiplexed metasurfaces, we show hybrid multiplexing of polarization, wavelength, and orbital angular momentum can be applied for dynamic tuning. Our strategy presents a highly compact and efficient solution for high‐capacity, multi‐dimensional holography, with promising applications in advanced displays, data storage, optical encryption, and
