Upcycling Water Pollutants Into Long‐Chain Polymers via Synergistic Interfacial Dechlorination and Organic Radical Stabilization

open access: yesAngewandte Chemie, EarlyView.
HEO‐regulated electronic structure drives nonradical PI activation, promoting ETP‐mediated polymerization of 4CP into high‐molecular‐weight products with enhanced surface enrichment. Concurrent dechlorination occurs via radical coupling and •OHads attack, enabling efficient carbon retention and selective product evolution at the liquid–solid interface.

Ultra‐Thin and Highly Insulating Aromatic Monolayers by N‐Heterocyclic Carbenes

open access: yesAngewandte Chemie, EarlyView.
By using N‐heterocyclic carbenes extremally insulating and at the same time as thin as 0.3 nm molecular films are formed. The charge transport calculations indicate absence of destructive quantum interference effect which was so far the only way to suppress conductivity in aromatic molecules.

Matching the Coupling of Valence Electrons in the Oxide Interface to Perturb the Magnetic Order Enhancing Oxygen Reduction in Zinc–Air Batteries

open access: yesAngewandte Chemie, EarlyView.
Sub‐5 nm Fe2O3/Sm2O3 heterojunction nanoparticles are anchored on nitrogen‐doped carbon nanofibers, featuring coupled Fe(3d)‐O(2p)‐Sm(4f) orbitals at the interface. The resulting super‐exchange induces antiparallel magnetic ordering at heterointerfaces, suppressing spin‐dependent interaction between surface OH* species and Fe sites to facilitate OH ...

Defect‐Guided Assembly of Aperiodic and Flexible Metal–Organic Frameworks From Pre‐Formed Cages

open access: yesAngewandte Chemie, EarlyView.
A cage‐directed strategy is used to program topologically correlated defects and induce aperiodicity in HKUST‐1‐type MOFs. A missing carboxylate group in the linker drives the formation of Cu‐vacancy domains, while Rh(II) cages spatially confine these defects.

Flexible AC Transmission System Controllers: An Evaluation

open access: yesMaterials Science Forum, 2010
Electricity market activities and a growing demand for electricity have led to heavily stressed power systems. This requires operation of the networks closer to their stability limits. Cost effective solutions are preferred over network extensions. The flexible alternating current transmission system (FACTS), a new technology based on power electronics,

Flexible AC Transmission Systems (FACTS) and Resilient AC Distribution Systems (RACDS) in Smart Grid

Proceedings of the IEEE, 2017
Transmission and distribution (T&D) networks are a critical part of the power grid. As moving towards a smart-grid, it is essential to modernize the T&D networks and make it “Smart-grid ready”. The concept of flexible ac transmission systems (FACTS) has been well-known for three decades.

Evolutionary fuzzy control of flexible AC transmission system

open access: yesIEE Proceedings - Generation, Transmission and Distribution, 2005
A fuzzy-controller design by the hybrid of genetic algorithm and particle-swarm optimisation (F-HGAPSO) is employed for a thyristor-controlled series capacitor (TCSC) to improve the transient stability of flexible AC transmission systems (FACTS). According to the variation of rotation speed, a fuzzy controller decides an approximate series capacitance ...
