Experimental study of a transformer with superconducting elements for fault current limitation and energy redistribution

, 2005
Numerous proposed and developed superconducting fault current limiters and self-limiting transformers limit successfully fault currents but do not provide uninterrupted supplying of consumers. A design investigated in the work combines the functions of a

Gram‐Scale Production of Iron Oxide Rubik‐Cube Nanoparticles: New Tools for the Clinical Translation of Magnetic Hyperthermia and Magnetic Particle Imaging

Advanced Functional Materials, EarlyView.
This work reports the first gram‐scale solvothermal synthesis of ‘Rubik's cube’ nanoparticles—cubic, dendritic multicore structures with tuneable sizes and exceptional magnetic heating performance. Featuring iron oxide single‐domain character, with low coercivity fields, high magnetization, and strong MPI signals, they enable viscosity‐independent ...

Stoma‐Shell Nanoarchitecture for Enhanced Plasma Confinement Catalysis in Synthesis of Ethanol from CO2

Advanced Functional Materials, EarlyView.
High‐energy electron impact in plasma catalysis often causes excessive dissociation of active intermediates, limiting C2+ product selectivity. To address this challenge, a bio‐inspired stoma‐shell nanoarchitecture is designed to decouple electron impact from catalytic reaction zones.

Dual‐Interface‐Dominant Cathode Architectures Enabling Fast Sulfur Redox and Stable Interfaces in All‐Solid‐State Li‐S Batteries

Advanced Functional Materials, EarlyView.
An optimized carbon host nanostructure enables a dual‐interface‐dominant architecture in sulfur cathodes of solid‐state Li‐S batteries by selectively forming sulfur|carbon and sulfur|solid electrolyte interfaces. This tailored interfacial configuration accelerates sulfur redox kinetics by establishing enriched Li+/e– transport networks, while ...

Dual‐Ligand Metal‐Organic Frameworks via In Situ Amidoxime Engineering for Selective Ion Separation

Advanced Functional Materials, EarlyView.
Inspired by microbial ion‐trapping mechanisms, a mild and universal strategy is developed to construct highly porous amidoxime‐functionalized MOFs. DFT calculations and molecular force measurements reveal that the dual‐ligand amidoxime configuration significantly strengthens Ga(III) affinity.
