A Novel Machine Learning-Based Short-Circuit Current Prediction Method for Active Distribution Networks

open access: yesEnergies, 2019
The traditional mechanism models used in short-circuit current calculations have shortcomings in terms of accuracy and speed for distribution systems with inverter-interfaced distributed generators (IIDGs).

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Effects of Transformers' Short-circuit Voltages and Short-circuit Powers of the Grid Equivalent on Short-circuit Current.

open access: yes, 2017
In power systems, the most dangerous condition in the electromagnetic transients is the short circuit. When short circuit occurs, circuit impedance falls, the current increases and the voltage drops. These changes cause dangerous consequences to the grid.

Research on transient of current transformers at short circuit. [PDF]

open access: yes, 2015
Current transformers errors highly increase at transient beginning, when faults occur. In order to ensure a proper relay protection performance, current transformer have to operate at right accuracy.

The effects of amiloride and age on oxygen consumption coupled to electrogenic sodium transport in the human sigmoid colon

open access: yesThe Saudi Journal of Gastroenterology, 2015
Background/Aim: Aerobic metabolism is necessary for ion transport in many transporting epithelia, including the human colonic epithelium. We assessed the effects of the epithelial sodium channel blocker, amiloride, on oxygen consumption and short-circuit

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

open access: yesAdvanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

open access: yesAdvanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...
