Dispersive X‐ray absorption spectroscopy using independent grazing‐incidence focusing and convexly bent Bragg‐crystal dispersing optics

open access: yesJournal of Synchrotron Radiation, Volume 32, Issue 4, Page 1068-1084, July 2025.
A dispersive X‐ray absorption spectroscopy instrument has been developed and implemented at the Advanced Photon Source's Advanced Spectroscopy Beamline. The instrument uses a convexly bent Bragg‐crystal analyzer to disperse a polychromatic X‐ray beam and independent Kirkpatrick–Baez mirrors for focusing, thereby providing a simple and flexible method ...

Multimodal Purcell enhancement and optical coherence of Eu3+ ions in a single nanoparticle coupled to a microcavity

open access: yesNanophotonics, Volume 14, Issue 11, Page 1817-1826, June 2025.
Abstract Europium‐doped nanocrystals constitute a promising material for a scalable future quantum computing platform. Long‐lived nuclear spin states could serve as qubits addressed via coherent optical transitions. In order to realize an efficient spin‐photon interface, we couple the emission from a single nanoparticle to a fiber‐based microcavity ...

Smart Polymeric 3D Microscaffolds Hosting Spheroids for Neuronal Research via Quantum Metrology

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
Development of a platform consisting of 3D microscaffolds supporting 3D embryoid bodies for neuronal research. The polymeric scaffolds enable directed growth of neurites. This study shows nanodiamond‐based quantum sensors graft onto the polymer material, enabling quantum metrology experiments within the 3D neuronal model and thereby providing a ...

Creation and investigation of nanopositioning systems

open access: yesMechanics, 2008
In the article the mathematical model of the developed nanoscanner is presented. The research results of static and dynamic precision integrating the experimental stand into LFM system are presented, too. Nanoscanner dynamics is expressed mathematically applying the Finite elements method.
