Electrically tunable terahertz resonance in antiferromagnetic NiO/Pt heterostructures
Published 2023“…A redshift of over 100 GHz in the NiO spin resonance frequency of around 1 THz is observed by applying charge currents along the adjacent Pt layer. A control experiment with NiO/Cu and temperature-dependent measurement confirm that the dominant tuning mechanism is Joule heating. …”

Highly anisotropic titanates from electrospun TiO2–SiO2 composite nanofibers and rice grain-shaped nanostructures
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
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. …”

Redundant Symmetry Influences Perceptual Grouping (as Measured by Rotational Linkage)
Published 2017-05-01“…Using the rotational linkage measure, we compared grouping for horizontally symmetric simple oblique lines and for lines composed of multiple conjoined orientations and found greater grouping for the more complex symmetric lines. A control experiment ruled out possible confounding factors and also showed a grouping effect of vertically aligned endpoints. …”

Research on the Control Performance of Depth-Fixed Motion of Underwater Vehicle Based on Fuzzy-PID
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.…”
