Cerium oxide nanoparticles have revolutionized the biomedical field and is still in very fast pace of development. Hence, this work elaborates the physicochemical properties, biosynthesis, and biomedical applications of cerium oxide nanoparticles.

This study reports plant mediated-copper oxide nanoparticles synthesis from Annona squamosa and their real-life application in agricultural domain for label-free detection of H2O2 and its antibacterial efficiency for combating rice crop pathogen.

Development of aluminum nitride (AlN)-single walled carbon nanotube (SWCNT) ceramic-matrix composite containing 1-6 vol% SWCNT by hot pressing has been reported in this article. The composites containing 6 vol% SWCNT are dense (~99% relative density) and show high dc electrical conductivity (200 Sm À1 ) and thermal conductivity (62 Wm À1 K À1 ) at room temperature. SWCNTs contain mostly metallic variety tubes obtained by controlled processing of the pristine tubes before incorporation into the ceramic matrix. Raman spectroscopy and field emission scanning electron microscopy (FESEM) of the fracture surface of the samples show the excellent survivability of the SWCNTs even after high-temperature hot pressing. The results indicate the possibility of preparation of AlN nanocomposite for use in plasma devices and electromagnetic shielding.
