ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.We use AI‐enhanced intensity modulation two‐photon excited fluorescence microscopy (ml‐IM2PM) to investigate defect properties and charge carrier recombination in MAPbBr3 films. Mapping exciton generation rate, trap concentration, and trap energy barriers and correlating spatially resolved charge carrier recombination pathways, we identify the ...

Flight measured and calculated exhaust jet conditions for an F100 engine in an F-15 airplane [PDF]
The exhaust jet conditions, in terms of temperature and Mach number, were determined for a nozzle-aft end acoustic study flown on an F-15 aircraft. Jet properties for the F100 EMD engines were calculated using the engine manufacturer's specification deck.

International Journal for Numerical Methods in Fluids, EarlyView.Compared to experimental data of thermophysical properties of NFs, semi‐empirical models cannot estimate FOM correctly. For all working fluids, applying a converging channel instead of the canonical case was inefficient. Diverging channel was always favored compared to the canonical case. For less effective NFs, both lowering the reference velocity and

Morphology and Mach Number Dependence of Subsonic Bondi–Hoyle Accretion
The Astrophysical JournalWe carry out three-dimensional computations of the accretion rate onto an object (of size R _sink and mass m ) as it moves through a uniform medium at a subsonic speed v _∞ . The object is treated as a fully absorbing boundary (e.g., a black hole).
