SCANNING ELECTRON MICROSCOPY (SEM) OF THE MAMMALIAN URINARY TRACT [PDF]

Pediatric Research, 1974
SEM permits characterization of the topography and individual cell surface of the urinary tract at the ultrastructural level. We have examined the entire urinary tract of the normal monkey, and the fusion of podocyte terminal processes in aminonucleoside-nephrotic rats using SEM. The podocyte has a central perikaryal region that branches into radiating

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
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 ...
