Advanced Functional Materials, EarlyView.A dye‐based photoinitiator acting as a structure‐directing element, guides the formation of a cholesteric polymer network that behaves as a chirped photonic structure with dissipative chiral coupling. Photopolymerization freezes a depth‐dependent helical pitch, broadening the Bragg resonance spectrum.

Jet noise source distribution for coplanar nozzles: experiments and predictions [PDF]
In this paper we study the mechanism of jet noise production in coaxial flows. We shall present various experimental results for isothermal and heated coplanar jet flows of four area ratios (0.81, 2, 3, and 4), operating at different velocity ratios ...

Submicron Metasurface Reconfigured Multiband Smart Windows
Advanced Functional Materials, EarlyView.This work presents a submicron metasurface reconfigured multiband thermochromic smart window. By integrating subwavelength nanostructures into a Fabry−Perot resonator configuration, it mitigates conventional trade‐offs to simultaneously deliver high luminous transmittance and robust solar heating and radiative cooling modulation capabilities ...

Volcanic jets to commercial jets: synopsis and diagnosis
Bulletin of VolcanologyAbstractAircraft encounters with volcanic ash have caused significant damage over the past 40 years, resulting in particular attention being given to the issue. We analyzed the volcanic ash-aircraft encounter database published by the USGS. We added new volcanic eruptions and parameters such as eruption types, and dry–wet. Then, we applied standard and
