    Highly anisotropic titanates from electrospun TiO2–SiO2 composite nanofibers and rice grain-shaped nanostructures by Sreekumaran Nair, A., Zhu, Peining, Jagadeesh Babu, Veluru., Yang, Shengyuan, Peng, Shengjie, Ramakrishna, Seeram

    Published 2013
    “…The titanates were thoroughly characterized by spectroscopy and microscopy. Control experiments with the respective TiO2 analogues revealed that the unique open and highly porous morphologies were the result of structural rearrangement of TiO2 coupled with the in situ leaching of SiO2 from the composites by the alkali. …”

    Chemo- and regioselective synthesis of acyl-cyclohexenes by a tandem acceptorless dehydrogenation-[1,5]-hydride shift cascade by Smith, L, Armstrong, R, Matheau-Raven, D, Donohoe, T

    Published 2020
    “…The reaction produces water and hydrogen gas as the sole byproducts and a wide range of functionalized acyl-cyclohexene products can be synthesized using this method in very high yields. A series of control experiments were carried out, which revealed that the process is initiated by acceptorless dehydrogenation of the diol followed by a redox-neutral cascade process, which is independent of the iridium catalyst. …”

    Research on the Control Performance of Depth-Fixed Motion of Underwater Vehicle Based on Fuzzy-PID by Ya Xie, Afei Zhu, Zhonghua Huang

    Published 2023-01-01
    “…The results show that the fuzzy-PID controller can realize the control of the underwater vehicle’s depth-setting motion, and the control effect was independent of the initial PID parameters, thus avoiding the dependence of the formulation of PID parameters on manual control experience. When the mass and hydrodynamic coefficient of the underwater vehicle change, the fuzzy-PID controller can still maintain good control performance and has strong adaptive ability.…”
