Differential coupling contributes to synchronization via a capacitor connection between chaotic circuits Regular Papers

Yu-meng XU, Zhao YAO, Aatef HOBINY, Jun MA

Frontiers of Information Technology & Electronic Engineering 2019, Volume 20, Issue 4,   Pages 571-583 doi: 10.1631/FITEE.1800499

Abstract: Then symmetric coupling and cross coupling are activated to detect synchronization stability, separatelyIt is found that resistor-based voltage coupling via a single variable can stabilize the synchronizationIt is also confirmed that the realization of synchronization is dependent on the selection of a couplingThe approach and stability of complete synchronization depend on symmetric coupling, which is activatedCross coupling between different variables just triggers phase synchronization.

Ying XIE, Zhao YAO, Jun MA

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 9,   Pages 1407-1420 doi: 10.1631/FITEE.2100563

Abstract: for neurons, and the realization of synchronization is helpful in maintaining energy balance betweenwith a constant step within a certain period until it reaches energy balance or complete synchronizationWhen two neurons become non-identical, phase synchronization can be controlled during the activationidentical neurons, the second criterion for taming synaptic intensity is effective for reaching complete synchronizationThis indicates that a synapse connection may prefer to enhance its coupling intensity exponentially.

Enhancing the aromatic selectivity of cyclohexane aromatization by CO2 coupling

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 11,   Pages 1801-1808 doi: 10.1007/s11705-023-2325-9

Abstract: Improving the aromatic selectivity in the alkane aromatization process is of great importance for its practical utilization but challenge to make because the high H/C ratio of alkanes would lead to a serious hydrogen transfer process and a large amount of light alkanes. Herein, CO2 is introduced into the cyclohexane conversion process on the HZSM-5 zeolite, which can improve the aromatic selectivity. By optimizing the reaction conditions, an improved aromatic (benzene, toluene, xylene, and C9+) selectivity of 48.2% can be obtained at the conditions of 2.7 MPa (CO2), 450 °C, and 1.7 h−1, which is better than that without CO2 (aromatic selectivity = 43.2%). In situ transmission Fourier transform infrared spectroscopy spectra illustrate that many oxygenated chemical intermediates (e.g., carboxylic acid, anhydride, unsaturated aldehydes/ketones or ketene) would be formed during the cyclohexane conversion process in the presence of CO2. 13C isotope labeling experimental results demonstrate that CO2 can enter into the aromatics through the formation of oxygenated chemical intermediates and thereby improve the aromatic selectivity. This study may open a green, economic, and promising way to improve the aromatic selectivity for alkane aromatization process.
