Article Synopsis
- The study investigates how palladium-lead membrane alloys change when interacting with hydrogen, using advanced X-ray diffraction and microscopy techniques.
- The focus is on optimizing these filters for high-purity hydrogen separation, which is increasingly important for various industrial applications.
- Key findings include how lead concentration affects the structure and properties of the membranes, revealing significant insights into hydrogen's impact on metal systems.
In the stoichiometric iron-based superconductor EuRbFeAs, superconductivity coexists with a long-range magnetic ordering in Eu layers. Using high-resolution transmission electron microscopy (HRTEM), we observed an atomic structure of as-grown EuRbFeAs crystals. HRTEM shows that crystals have two-dimensional intrinsic nanoinclusions established to be the RbFeAs (122) phase with a volume fraction of ~5.

The artificial pinning centers have adopted columnar morphology with average diameter of about 8 nm (BaSnO-doped sample) and 6.5 nm (BaZrO-doped sample) and density of 500 μm for the both samples.
