“…Furthermore, the RLs demonstrated a low loss, which was attributed to the weak absorption of the skeleton. Recently, Chen et al reported random lasing from the photonic crystal of butterfly wings [16] and parrot feathers [17] embedded with pyrromethene (PM597) dye. It was also shown that the quasi-periodic arrangement of textures on the butterfly wings and parrot feathers could effectively scatter light for random emission.…”

In this study, we demonstrate a simple approach to fabricate a high-performance random laser from the natural inverse photonic glass structure of Artemia eggshells. Herein, the three-dimensional structures of Artemia eggshells provide an ideal scattering medium with a significantly high-reflectance stopband which facilitates resonance feedback for random lasing action. By doping organic dye molecules into the Artemia eggshells, random lasers are realized by optical pumping with a threshold of 79 μJ/mm2, and a quality (Q) factor of 2328. In comparison with other works on random lasers from natural photonic crystals such as butterfly wings, our random lasers demonstrate a significantly lower lasing threshold and a comparable Q factor. Our results indicate that the natural inverse photonic glass structure is not only served as an effective scattering medium for random lasing but also paves a novel approach in designing and fabricating bio-controlled photonic devices.

“…This can be useful in a variety of applications, such as noise reduction in buildings, acoustic isolation in machinery, or soundproofing in vehicles. This effect is similar to the photonic bandgap in optics, 13,40 which refers to a range of frequencies in which electromagnetic waves are strongly absorbed or reflected by a material or structure. We can find that except for a single bandgap of the primitive-based lattice, other TPMS-based structures show multiple acoustic bandgaps in the sub-2000 Hz frequency range.…”

Poly(methyl methacrylate)-based triply periodic minimal surfaces (TPMS) structures promise great potential in phononic applications, but the complicated TPMS structure induces a design challenge for controlling their properties. Numerical acoustic simulations of seven major PMMA-based TPMS lattice structures are presented for low-frequency sound attenuation applications while varying their relative density. Except for the local resonances in primitive and Neovius-based lattice structures, the acoustic properties of other TPMS structures show a common Bragg bandgap with a central frequency of around 435 Hz and a bandwidth of around 286 Hz, which results from multiple scattering of periodic unit cells. In contrast, the acoustic bandgaps of primitive and Neovius-based lattices have much smaller and larger complete bandgaps, respectively, which are mainly attributed to the local resonances in their geometric cavities with different sizes. Thus, by taking the mechanism of generated bandgaps in the TPMS-based lattice structures into consideration, we can design suitable bandgaps for acoustic applications in the specific frequency range.

“…4, the barbules of the green feathers were dark grey and, most likely, the melanin stored in the barbules absorbed the laser radiation causing thermal damage and discoloration. Note that red and yellow feathers also contain some melanin granules but these are embedded deeply within the barbules [51] (when viewed with the microscope, the barbules of red and yellow feathers were red and yellow respectively, not grey). The green colour of feathers is the result of the presence of biopigments, but also structural effects.…”

A dual-wavelength Q-switched Nd:YAG laser emitting at 1064 nm and 532 nm and an Er:YAG laser were tested on a range of feathers containing melanin, carotenoids and psittacofulvins. Dyed, white and iridescent feathers, as well as down feathers, were also included in the study. First, the damage threshold fluence was determined for each type of feather and then, as appropriate, laser tests were conducted on feathers artificially soiled with dust or carbon black. The Nd:YAG laser was unsuccessful at cleaning feathers soiled with carbon black. Better outcomes were obtained on feathers soiled with dust: the Nd:YAG laser was effective at both wavelengths at removing dust from white feathers, dyed feathers and yellow feathers containing psittacofulvins. Feathers containing melanin, as their main colourant, were found to have a much lower damage threshold fluence than other feathers. Also, laser radiation at 532 nm at high fluences can cause discolouration on pink feathers containing carotenoids. Finally, it was not possible to remove dust from down feathers without causing thermal damage. This investigation showed that laser cleaning using a Q-switched Nd:YAG laser can remove dust from certain types of feathers. However, further research is needed to assess any potential chemical or long-term effects of laser cleaning on feathers. Finally, the Er:YAG laser was found to be unsuitable for laser cleaning resulting in thermal damage to all feathers at low fluences.
