Generation of human antibodies targeting human platelet antigen (HPA)-1a.

Background: Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is a condition during pregnancy, which can lead to thrombocytopenia and a bleeding tendency with intracranial hemorrhage (ICH) being the most concerning complication in the fetus or neonate. An incompatibility between human platelet antigen (HPA)-1a accounts for the majority of FNAIT cases. Binding of HPA-1a-specific alloantibodies to their target on fetal platelets and endothelial cells can induce apoptosis of megakaryocytes, disrupt platelet function, and impair angiogenesis.

Crystal Structure and Ferromagnetism of the CeFeSi Intermetallic Compound.

We have determined the crystal structure and the magnetic state of the CeFeSi intermetallic compound. Our revised structural model (fully ordered tetragonal unit cell, 4/) agrees with the previous literature report, except for some minor quantitative differences. Magnetically, the CeFeSi undergoes a ferromagnetic transition at the temperature ≈ 94 K.

Revealing the Epitaxial Interface between AlFe and AlFe Enabling Atomic Al Interdiffusion.

Steel is the most commonly manufactured material in the world. Its performances can be improved by hot-dip coating with the low weight aluminum metal. The structure of the Al∥Fe interface, which is known to contain a buffer layer made of complex intermetallic compounds such as AlFe and AlFe, is crucial for the properties.

X-ray photoelectron diffraction study of the approximant AlCo(001) quasicrystal.

The intermetallic AlCo is defined as a structurally complex material and is considered a low-order quasicrystalline approximant. A single crystal of AlCo(001) was obtained by the Czochralski method. The sample was characterized by X-ray photoelectron spectroscopy (XPS), low-energy electron diffraction (LEED), and X-ray photoelectron diffraction (PED).

Probing spin fluctuations of the quantum phase transition in CeAl by muon spin rotation.

We report on the dynamics of a magnetic-field-driven antiferromagnetic-to-paramagnetic quantum phase transition in monocrystalline CeAl via transverse-field muon spin rotation (TF-µSR) experiments down to low temperature of [Formula: see text] 80 mK. The quantum phase transition is of a spin-flip type and takes place on the Ce-Al magnetic chains as a result of competition between the indirect exchange and the Zeeman interaction of the Ce moments with the external field, applied along the chain direction (also the direction of the antiferromagnetic axis). The Ce moments are not static at [Formula: see text] 0, but fluctuate in their direction due to the Heisenberg uncertainty principle.
