    Insights Into the Role of CircRNAs: Biogenesis, Characterization, Functional, and Clinical Impact in Human Malignancies by Nisar, Sabah

    Published 2021
    “…Compared to the linear RNA, circRNAs are produced differentially by backsplicing exons or lariat introns from a pre-messenger RNA (mRNA) forming a covalently closed loop structure missing 3′ poly-(A) tail or 5′ cap, rendering them immune to exonuclease-mediated degradation. …”

    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. …”

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

    Published 2017
    “…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. …”
