Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Fault Ride Through approach for Grid-Connected Photovoltaic System

e-Prime: Advances in Electrical Engineering, Electronics and Energy, 2023
This paper presents a fault ride-through approach for grid-connected photovoltaic (PV) systems, aimed at improving the system's response during voltage sags and limiting the maximum inverter current during symmetrical faults.

Fault Ride-Through Study of Wind Turbines

Journal of Power and Energy Engineering, 2013
The installation of wind energy has increased rapidly around the world. The grid codes about the wind energy require wind turbine (WT) has the ability of fault (or low voltage) ride-through (FRT). To study the FRT operation of the wind farms, three methods were discussed.

Tailored Diketopyrrolopyrrole Derivatives for Efficient Deep‐Red Organic Lasers

Advanced Functional Materials, EarlyView.
Tailored diketopyrrolopyrrole derivatives exhibit high stable amplified spontaneous emission with single or dual bands. Incorporated into distributed‐feedback lasers based on one‐ and two‐dimensional dichromated‐gelatin diffractive gratings, these materials provide a robust, flexible platform for integrated organic deep‐red light sources. ABSTRACT Deep‐

Mitochondria and Neuromast Tagging With Fluorescent Gallium‐Triapine Analogues: In Cellulo MP FLIM and Zebrafish Live Imaging

Advanced Science, EarlyView.
Fluorescent BODIPY‐conjugated thiosemicarbazone ligands and their Ga(III), In(III), and Fe(III) complexes, inspired by Triapine, are developed as theranostic agents. Multiphoton FLIM and confocal microscopy in cancer cells and zebrafish reveal real‐time uptake, mitochondrial localisation, and whilst spectroscopic assays indicated preserved complex ...

Voluntary Collective Action to Address Growing Agricultural Challenges in Two Countries: Experimental Insights and Commonalities

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT We conducted two framed field economic experiments with citrus farmers in Florida, United States and soybean farmers in Argentina to investigate their willingness to coordinate pest and weed management efforts. Despite the contrast between these two agricultural contexts, we find striking behavioral commonalities.

A grid side fault ride-through control for renewable energy connected MMC-HVDC

电力工程技术
Renewable energy connected modular multilevel converter high-voltage direct-current (MMC-HVDC) system should have the capability of fault ride-through when the AC grid fails. However, it is difficult to quickly and reliably achieve fault ride-through via

Hierarchical control-based fault ride-through of VSC-HVDC considering impacts of renewable energy

International Journal of Electrical Power & Energy Systems
When a short-circuit fault occurs at the receiving-end grid, the unbalanced power in voltage source converter based high voltage direct current (VSC-HVDC) should be consumed to prevent excessive DC voltage rise, thereby enabling fault ride-through ...

Direct vs. Indirect Control Schemes for Grid-Forming Inverters–Unveiling a Performance Comparison in a Microgrid

IEEE Access, 2023
This article provides insights into the dynamic performance of indirect and direct control strategies for grid-forming (GFM) inverters. The indirect method for grid-forming inverters utilizes three cascaded stages to produce the reference signal sent to ...

Decentralised control and fault ride‐through of a multi‐microgrid system [PDF]

IET Smart Grid, 2019
A multi‐microgrid (MMG) system comprises of a cluster of microgrids interconnected for reliable and efficient operation in grid connected as well as islanded modes. In this study, the fault‐ride‐through capability of an MMG system is addressed. A solution to under‐voltage and over‐current scenarios arising due to severe short‐circuit faults in inverter‐
