Spherical Spiky Zno/Au Nanostructures For Efficient Photoelectrochemical Watersplitting, Kouroush Sali̇mi̇
Turkish Journal of Chemistry
Spiky zinc oxide (ZnO)/Au nanostructures with spherical shape-defined morphologies were synthesized using polydopamine as a starting template for photoelectrochemical H2 production under visible light-emitting diode (LED) illumination. This low-temperature processing technique not only facilitated the fabrication of ideal plasmon-sensitive heterostructures, but also enhanced the electron mobility of the photoanodes, reaching 5.7 mA/cm² [at 1.0 V vs. the reversible hydrogen electrode (RHE)] under visible LED illumination (30 mW/cm2). This notable value was 28 times greater than that observed under dark conditions, primarily attributed to the close Schottky contact between the Au and ZnO spikes.

Fuzzy-Virtual Inertia Control To Improve The Frequency Response Of Multi-Area Power Systems, Nourelhouda Djaraf, Yacine Daili, Abderrahim Zemmit, Abdelghani Harrag
Turkish Journal of Electrical Engineering and Computer Sciences
Virtual inertia control (VIC) is essential for power systems dominated by electronic devices to compensate for the lack of inertia and ensure frequency regulation. However, most existing VICs often focus solely on optimizing the virtual inertia parameter to adapt to the high penetration of renewable energy sources (RESs) without considering the damping factor. This oversight can lead to significant fluctuations and power mismatches, especially in interconnected systems where the coordination between MGs is sensitive and essential, and there is a risk of propagation of deviations between MGs, which makes the control more complex. To address these issues, this paper presents …
