Decay of Europium-154

Physical Review, 1957
The gamma rays and electrons of fission-product europium (${\mathrm{Eu}}^{153}$, ${\mathrm{Eu}}^{154}$, and ${\mathrm{Eu}}^{155}$) have been studied, and the results obtained for ${\mathrm{Eu}}^{154}$ are presented. Gamma rays belonging to this isotope have been identified at 0.1229 Mev (35%), 0.2480 Mev, ${0.593}_{3}$ Mev (4%), ${0.694}_{1}$ Mev ...

On europium digallides

Zeitschrift für anorganische und allgemeine Chemie, 2023
AbstractThe europium gallide Eu1‐xGa2+3x (x is between 0.06 and 0.07) has been synthesized and its crystal structure has been refined from single crystal X‐ray diffraction data. Eu1‐xGa2+3x crystallizes with hexagonal structure related to the AlB2‐type (space group P6/mmm, a=4.354 Å, c=4.485 Å).

Sequential Regulation of Neurovascular Bone Regeneration in Large Bone Defects Using Black Phosphorus‐Europium Nanosheet Integrated TPMS Biomimetic Scaffold with Photo‐Controlled Ion Release

Advanced Science, EarlyView.
TPBE scaffolds, in conjunction with mild photothermal effects, effectively activate the PI3K/Akt signaling cascade, thereby promoting early neuronal differentiation and neurite growth. Short‐term (12 W) in vivo implantation studies revealed no significant pathological damage to major organs, providing preliminary evidence of the material's excellent ...

Transport–Reaction–Signal Coupling in Lateral Flow Assays for Next‐Generation Point‐of‐Care Diagnostics

Advanced Science, EarlyView.
Lateral flow assays are evolving into interdisciplinary, system‐level sensing platforms. Recent innovations are deconstructed through coupled phases of mass transfer, reaction, and signal transduction, revealing interdependence across porous materials, interfacial chemistry, nanolabels, readout devices, and data‐enabled analysis.

Europium Nitride from Sponge Europium and Ammonia.

NIPPON KAGAKU KAISHI, 1993
In order to obtain pure EuN powder, sponge Eu was prepared by evacuation of NH3 under 10-s Torr from an Eu solution of liquid NH3 a part of impurities in which was removed by dissolution of Eu. The resulting sponge Eu contained 2-3% of Eu(NH2)2 and a small amount of Eu(OH)3.

Superconductivity with Europium [PDF]

Physics Letters A, 1979
Abstract EuIr 2 becomes superconducting at 0.2 K. Arc melting this compound raises T c to 2.6 K, in an apparently different and unidentified structure. These are the first superconductors containing Eu.
