Transforming solid-state precipitates via excess vacancies [PDF]
Nature Communications, 2020 AbstractMany phase transformations associated with solid-state precipitation look structurally simple, yet, inexplicably, take place with great difficulty. A classic case of difficult phase transformations is the nucleation of strengthening precipitates in high-strength lightweight aluminium alloys.

Finding transition states for crystalline solid–solid phase transformations [PDF]
Proceedings of the National Academy of Sciences, 2005 We present a method to identify transition states and minimum energy paths for martensitic solid–solid phase transformations, thereby allowing quantification of the activation energies of such transformations. Our approach is a generalization of a previous method for identifying transition states for chemical reactions, namely the climbing image-nudged

Stability Assessment of Voltage Control Strategies for Smart Transformer-Fed Distribution Grid
IEEE Access, 2020 The smart transformer (ST), a solid-state-based transformer with control and communication functionalities, determines the voltage of the low voltage (LV) network. Due to the similar control purpose, the classic multiple feedback loop (multiloop) voltage

Overloading Scenario in Solid State Transformer [PDF]
2020 11th International Renewable Energy Congress (IREC), 2020 Nowadays, solid state transformer (SST) is been considered as an alternative option in smart grid where additional ancillary services that cannot be provided by conventional line frequency transformer (LFT) are required. However, the power transmission capability of SST is limited to that of its semiconductor switches which are power electronics ...
