In this work we performed a comparative study regarding the performance characteristics of three photochemical treatments for Brilliant Blue degradation: photolysis (only UV radiation), irradiation in the presence of H2O2 (H2O2 /UV), photo-Fenton reaction (Fe2+/H2O2 /UV). The kinetic analysis revealed that BB degradation follows an apparent first order kinetics. The examination of the estimated rate constants and the degradation efficiencies revealed the superior performance of the photo-Fenton oxidation, which may be due an increased gain of reactive oxygen species species comparative to the UV or UV/H2O2 treatment.
Gold gyroid optical metamaterials are known to possess a reduced plasma frequency and linear dichroism imparted by their intricate subwavelength single gyroid morphology. The anisotropic optical properties are, however, only evident when a large individual gyroid domain is investigated. Multidomain gyroid metamaterials, fabricated using a polyisoprene-$b$-polystyrene-$b$-poly(ethylene oxide) triblock terpolymer and consisting of multiple small gyroid domains with random orientation and handedness, instead exhibit isotropic optical properties. Comparing three effective medium models, we here show that the specular reflectance spectra of such multidomain gyroid optical metamaterials can be accurately modeled over a broad range of incident angles by a Bruggeman effective medium consisting of a random wire array. This model accurately reproduces previously published results tracking the variation in normal incidence reflectance spectra of gold gyroid optical metamaterials as a function of host refractive index and volume fill fraction of gold. The effective permittivity derived from this theory confirms the change in sign of the real part of the permittivity in the visible spectral region (so, that gold gyroid metamaterials exhibit both dielectric and metallic behavior at optical wavelengths). That a Bruggeman effective medium can accurately model the experimental reflectance spectra implies that small multidomain gold gyroid optical metamaterials behave both qualitatively and quantitatively as an amorphous composite of gold and air (i.e., nanoporous gold) and that coherent electromagnetic contributions arising from the subwavelength gyroid symmetry are not dominant. ; This research was supported through the Swiss National Science Foundation through the National Center of Competence in Research Bio-Inspired Materials and grant numbers 200021_163220 (to U.S.) and PZ00P2_168223 (to B.D.W.), the Adolphe Merkle Foundation, the Engineering and Physical Sciences Research Council (EPSRC) through the Cambridge NanoDTC EP/G037221/1, EP/L027151/1, and EP/ G060649/1, and ERC LINASS 320503 and from the European Union's Horizon 2020 Research and Innovation Programme under the Marie Sklodowska-Curie grant agreement no. 706329 (to I.G.).
