Protection Coordination in Networks with Renewable Energy Sources

open access: yes, 2014
The increased distributed generators (DGs) in distribution networks are causing protection coordination problems. Due to the many generation sources supplying the distribution network, the conventional protective devices have become insufficient to ensure the proper protection coordination in case of a fault.This dissertation illustrates the summary of

Artificial Amorphous Interface Matters for Boosting High‐Voltage Stable LiCoO2 Cathode

open access: yesAdvanced Functional Materials, EarlyView.
The amorphization of phosphate‐based surface layer with favorable Li‐ion conducting kinetics is realized by precisely tailored atomic‐level fabrication. This amorphous coating enables the lithium cobalt oxide (LCO) cathode superior high‐voltage rate capability and cycling performance, owing to the fast interfacial ionic transport and maintained ...

Atomic‐Scale Light Coupling Control in Ultrathin Photonic Membranes

open access: yesAdvanced Functional Materials, EarlyView.
Ultrathin photonic nanomembranes provide atomic‐scale control over the coupling between incident light and high‐Q photonic modes, enabling angstrom‐level resonance tuning and strong field confinement. When integrated with TMD monolayers, they further yield enhanced light–matter interactions, offering a versatile platform for advancing quantum photonics,

Structural Porosity and Low Mineral Density in Enamel Rods Drive Molar Incisor Hypomineralisation

open access: yesAdvanced Functional Materials, EarlyView.
This study uses advanced imaging modalities on multiple length scales to show that molar‐incisor hypomineralization does not present as a locally homogeneous pathology. Instead, microstructural defects, characterized through non‐mineralized, protein‐rich sheaths and an altered mineral structure in between prism rods, resulting in local differences in ...
