Features of liquid fuel burning in a narrow channel
Journal of Physics: Conference Series, 2017 The paper deals with experimental investigations of the surface perturbation effects on the flame propagation velocity along the surface of the liquid. It is revealed that at low velocities the effect is quite significant. Under certain conditions the flame even stabilizes for some time.

Advanced Functional Materials, EarlyView.Metasurfaces and other structured photonic environments can dramatically modify the absorption and/or light emission of semiconductors. However, the consequences of these changes on the temperature of the system are not well understood. The authors address this problem for colloidal nanocrystals and leverage their findings to convert light into ...
