Buoy‐Based Detection of Low‐Energy Cosmic‐Ray Neutrons to Monitor the Influence of Atmospheric, Geomagnetic, and Heliospheric Effects

Earth and Space Science
Cosmic radiation on Earth responds to heliospheric, geomagnetic, atmospheric, and lithospheric changes. In order to use its signal for soil hydrological monitoring, the signal of thermal and epithermal neutron detectors needs to be corrected for external

Investigation of Serrated Flow in Intercritically Annealed Medium Manganese Steel by In Situ Synchrotron X‐Ray Diffraction

steel research international, EarlyView.
Serrations and stepwise austenite phase transformation were observed in cold‐rolled and annealed medium manganese steels. By in situ XRD experiments, these two phenomena were studied simultaneously. The results show that DSA leads to the creation of PLC bands and load drops in the specimen.

Crystal Structures and Magnetic Properties of Coordination Polymer Complexes of Metal Ions With Kojic Acid Ligands

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
One‐dimensional coordination polymers of Cu(II) and Co(II) with kojic acid show distinct chain connectivities revealed by X ray crystallography and exhibit extremely weak magnetic interactions, as supported by magnetic measurements and molecular orbital calculations. The crystal structures and magnetic properties of coordination complexes [Cu(C6H5O4)2]

Shannon sampling based approach for the structural solution of nano‐objects by laboratory and synchrotron SAXS data

Journal of Applied Crystallography, EarlyView.
We present a model‐independent approach based on the Shannon sampling theorem to retrieve key structural parameters of proteins and core–shell micelles directly from small‐angle X‐ray scattering (SAXS) profiles. By bypassing the pair distribution function, the method overcomes q‐truncation artifacts and provides reliable mass, size and aggregation ...

Mobile electromagnetic levitator for time‐resolved in situ X‐ray diffraction studies of high‐temperature phase transformations

Journal of Synchrotron Radiation, EarlyView.
A mobile electromagnetic levitator combined with time‐resolved synchrotron X‐ray diffraction enables in situ studies of high‐temperature phase transformations without container‐induced contamination and reveals the first direct observation of metastable phase formation in undercooled Fe–Co alloys.In situ observations of high‐temperature transformations,

A Systematic NLTE Study of Very Metal-poor Stars with Metallicity down to −4.3 dex. VI. Light Neutron-capture Elements and the Sr–Na Correlation as a Signature of Spinstar Nucleosynthesis in the Early Galaxy

The Astrophysical Journal
We present a non–local thermodynamic equilibrium (NLTE) abundance analysis of the light neutron-capture elements Sr, Y, and Zr in a sample of 103 very metal-poor stars spanning −4.3 ≲ [Fe/H] ≲ −1.7, based on high-resolution Subaru/HDS spectra and ...

Transporter‐Associated Therapeutic Efficacy of an SMVT‐Targeted Boron Carrier in Boron Neutron Capture Therapy

Cancer Science, EarlyView.
The transporter‐associated BNCT strategy using BBCIP with or without BPA according to tumor transporter characteristics. BPA showed greater efficacy in LAT1‐dominant F98 glioma, whereas BBCIP was more effective in SMVT‐high CRL1666 tumors, suggesting the potential utility of transporter‐based boron carrier selection in BNCT.
