    Numerical investigation of steady air injection flow to control rotating stall in centrifugal compressors by Halawa, Taher

    Published 2014
    “…Numerical model was built to simulate high speed transonic centrifugal compressor working at an operating point close to surge. Air was injected at 12 locations at the vaneless region between the impeller and the diffuser at shroud surface with 5 different injection angles and 3 different injection mass flow rates. …”

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

    Published 2023
    “…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. …”
