Abstruct-When a generator of a heavily loaded electric power system reaches a reactive power limit, the system can become immediately unstable and a dynamic voltage collapse leading to blackout may follow. We study the statics and dynamics of this mechanism for voltage collapse by example and by the generic theory of saddle node and transcritical bifurcations. Load power margin calculations can...

This article describes the underpinning research, development, construction, and testing of a 4-MW multithree phase generator designed for hybrid-electric aircraft propulsion system demonstrator. The aim work is to demonstrate gravimetric power densities around 20 kW/kg, as required multi-MW systems. key design choices, development procedures, tradeoffs, together with experimental this electric...

Moist-Electric Energy Generation In article number 2300398, Lin Li and co-workers report a high-performance, stretchable, flexible moist-electric generator via molecular engineering of hydrogels. The integration generators with wearable electronics makes it possible to continuously harvest the moisture energy contained in human breath for generating electricity. This work broadens application s...

Electrochemotherapy is an effective local treatment of solid tumours which combines delivery of chemotherapeutic drug and electric pulses. Electric pulses increase permeability of plasma membrane transiently and reversibly, leading to increased transport of the drug into the cell. As all clonogenic cells in the tumour need to be eradicated for effective treatment, all cells have to be permeabil...
