We demonstrated that magnetic properties of porous iron oxide nanorods obtained by hydrogenation of hematite nanorods at several annealing temperature (523, 573, 623, and 673 K). The iron oxide and reduced iron oxide layer in iron oxide nanocomposite

We prepared Cr microspheres by using the spark erosion method. The Cr microspheres were treated under high oxygen pressures up to 40 MPa, and chromium oxide shells were induced. It is found that Cr 2 O 3 is more stable under 40 MPa of oxygen at both
