The effect of iron catalyzed graphitization on the textural properties of carbonized cellulose: Magnetically separable graphitic carbon bodies for catalysis and remediation [PDF]
, 2016 Whereas pyrolysis of pristine microcrystalline cellulose spheres yields nonporous amorphous carbon bodies, pyrolysis of microcrystalline cellulose spheres loaded with iron salts leads to the formation of magnetically separable mesoporous graphitic carbon

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.Abstract Novel compositionally complex borides, (Hf,Zr,Nb,Ti)B2 and (Hf,Zr,Nb,Ti)B2‒LaB6, were fabricated using spark plasma sintering process. (Hf,Zr,Nb,Ti)B2‒LaB6 exhibits a dual‐phase microstructure, in which (Hf,Zr,Nb,Ti)B2 is a primary phase with the hexagonal structure and LaB6 is a secondary phase with a cubic structure.

THE CARBOTHERMIC REDUCTION OF URANIUM OXIDE
, 1957 Uranium oxide has been reduced by carbon under vacuum at 225O deg C, to yield a product consisting of dendritic uranium carbide in a matrix of uranium. Uranium sponge is obtained from this cermet by hydrolyzr-ng the interconnected UC. This is followed by pickling in dilute nitric acid to remove the residual hydrolysis product UO/sub 2/ x H/sub 2/O from
