A real‐time correction method for sample drift in STXM based on Fourier transform image registration

Journal of Synchrotron Radiation, EarlyView.
This study proposes an online drift‐correction method for scanning transmission X‐ray microscopy that integrates Fourier‐transform image registration with laser‐interferometer feedback, suppressing sample drift in a 100‐image stack scan from over 1 mm to below 120 nm and thereby eliminating redundant scan area while markedly enhancing experimental ...

Monolithic integration of SiC diode detectors into scanning X‐ray microscopy optical elements for in situ beam diagnostics

Journal of Synchrotron Radiation, EarlyView.
Silicon carbide detectors are monolithically integrated into order‐sorting apertures and center stops for in situ soft X‐ray beam diagnostics in STXM. Functionalized components enable simultaneous monitoring of incident beam intensity and the transverse position at sample‐relevant locations without degrading optical performance.Reliable monitoring of ...

Quantification of 10B and 11B in Biological Samples in Translational Science and Clinical Applications for Boron Neutron Capture Therapy (BNCT)

Medicinal Research Reviews, Volume 46, Issue 5, Page 1362-1389, September 2026.
ABSTRACT Boron neutron capture therapy (BNCT) is a targeted radiotherapy that exploits the selective accumulation of the 10B isotope within tumors, followed by irradiation with low‐energy neutrons to induce high linear energy transfer particles with short path lengths, resulting in localized tumor cell destruction while sparing surrounding healthy ...

STXM observation and quantitative study of magnetic vortex structure

Acta Physica Sinica, 2015
Magnetic recording has now played an important role in the development of non-volatile information storage technologies, so it becomes essential to quantitatively understand the magnetization distribution in magnetic microstructures. In ferromagnetic disks, squares and triangles with submicron sizes, it is energetically favorable for the magnetization ...

Magnetic studies of magnetotactic bacteria by soft x-ray STXM and ptychography [PDF]

AIP Conference Proceedings, 2016
Magnetotactic bacteria (MTB) biomineralize chains of nanoscale magnetite single crystals which align the cell with the earth’s magnetic field and assist the cell to migrate to, and maintain its position at, the oxic-anoxic transition zone, their preferred habitat.

Passivierung von Defektzuständen in organischen n‐Typ‐Ladungstransferkomplexen durch molekularen Sauerstoff

Angewandte Chemie, Volume 138, Issue 33, 10 August 2026.
O2 verbessert den Ladungstransfer in organischen n‐Typ‐Donor‐Akzeptor‐Ladungstransferkomplexen (CTCs) durch physisorptive Passivierung von Ladungsträgerfallen. Durch die Unterdrückung der Rekombination und die Förderung langlebiger delokalisierter Ladungsträger verbessert O2 den Elektronentransport und die Leitfähigkeit ohne Dotierung.

Morphology and mixing of black carbon particles collected in central California during the CARES field study [PDF]

Atmospheric Chemistry and Physics, 2016
Aerosol absorption is strongly dependent on the internal heterogeneity (mixing state) and morphology of individual particles containing black carbon (BC) and other non-absorbing species.

Molecular Dioxygen‐Mediated Passivation of Electron Traps in n‐Type Organic Charge‐Transfer Complexes

Angewandte Chemie International Edition, Volume 65, Issue 33, 10 August 2026.
O2 enhances charge‐transfer in n‐type organic donor–acceptor charge‐transfer complexes (CTCs) via physisorption‐mediated trap passivation. By suppressing recombination and promoting long‐lived delocalized charge carriers, O2 improves electron transport and conductivity without doping.

Bias‐Engineered Synthetic Antiferromagnets Hosting Sub‐20 nm Zero‐Field Skyrmions at Room Temperature

Advanced Science, Volume 13, Issue 46, 17 August 2026.
A fully compensated synthetic antiferromagnet (SAF) multilayer exhibits a uniform state at zero field, without skyrmions. We use a SAF bias system to provide RKKY‐mediated exchange bias to the SAF multilayer, promoting zero‐field skyrmion stabilization and polarity control.

Oxygenated organic functional groups and their sources in single and submicron organic particles in MILAGRO 2006 campaign [PDF]

Atmospheric Chemistry and Physics, 2009
Fourier Transform Infrared (FTIR) and X-ray Fluorescence (XRF) were used to measure organic functional groups and elements of submicron particles collected during MILAGRO in March 2006 on three platforms: the Mexico City urban area (SIMAT), the high ...
