ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Local boron doping quantification in homoepitaxial diamond structures [PDF]
The capability of transmission electronmicroscopy (TEM) using the high angle annular dark fieldmode (HAADF,also labelled Z-contrast) to quantify boron concentration, in the high doping range between 1019cm−3 and 1021cm−3, is demonstrated.

Advancements in the investigation of radioactive microspheres for brachytherapy
In clinical practice, the management of most non-surgically resectable solid tumors necessitates a multidisciplinary treatment approach. Optimal solutions involve the integration of local and systemic treatments, such as targeted immunotherapy and ...
