Structural influence of chromium substituted magnetite ferrofluids on the optical and antibacterial characteristics حسب Babukutty, B.

"…As the composition of Cr increases from x = 0.2 to x = 0.8, the crystalline size decreases reaching a minimum value of 9 nm. At the same time, the magnetic moment also becomes 1.3 +- 0.08 at a saturation point of 33 +- 0.13 emu/g at the highest Cr composition. …"

Effect of reinforcement concentration on the properties of hot extruded Al-Al2O3 composites synthesized through microwave sintering process حسب Reddya, M. Penchal

"…Results showed that, as the content of hard ceramic particles increases, it improves overall mechanical properties including microhardness, 0.2% yield strength, ultimate compression/tensile strength, and Young's modulus while the ductility and co-efficient of thermal expansion decreases. XRD patterns and SEM/EDS mapping images show a uniform distribution of Al2O3 particles in the Al matrix. …"
