Ignition characteristics of nitromethane-doped ethanol in a heated shock tube
Ignition delay times of nitromethane-doped ethanol dual fuels are measured under the micro-combustion engine conditions (8 × 105 Pa and 904–1477 K). The promotion effect of nitromethane on ethanol ignition is more pronounced at a fuel-lean condition;

Nitride MXenes remain constrained by a persistent gap between computational prediction and experimental realization. This Review identifies the thermodynamic, kinetic, and chemical barriers limiting their synthesis, critically evaluates emerging fabrication routes, and proposes a multidimensional computational‐experimental framework to accelerate the ...

A post‐growth method is demonstrated to realize energy‐tunable quantum emitters in GaAs/GaAsN/GaAs core–multishell nanowires on a Si substrate. By combining the N‐induced bandgap reduction with H‐ion irradiation, the GaAsN potential landscape is engineered, enabling isolated, narrow emission lines that function as single‐photon sources with g(2)(0) ∼ 0.

A Bayesian approach to the determination of ignition delay [PDF]
A novel in-cylinder pressure method for determining ignition delay has been proposed and demonstrated. This method proposes a new Bayesian statistical model to resolve the start of combustion, defined as being the point at which the band-pass in-cylinder
