NUMERICAL INVESTIGATION OF DIFFERENT INJECTION PATTERNS IN ROTATING DETONATION ENGINES

, 2015
Previous numerical simulations of the hydrogen-air rotating detonation engine have been carried out using a simple fuel-injection pattern. This pattern assumes that the fresh gas mixture is injected through every point of the head-wall.

Determining the Relationship Between Composition, Structure, and Device Properties of GexSe1‐x‐Based Selector‐Only Memory

Advanced Electronic Materials, EarlyView.
Composition‐dependent structural evolution in GeXSe1‐X selector‐only memory (SOM) is correlated with device switching behavior. Increasing Ge strengthens network rigidity, suppresses atomic motion, and stabilizes threshold switching, while narrowing the memory window. The revealed structure–property relationship provides a guideline for compositionally
