Iridescence on Screen: Media Stereotype and Representation of LGBTQ+ in South Korean Television Dramas
This dissertation explores how Korean television dramas represent the LGBTQ+ community, including recent changes, prospects, and limitations. 25 television dramas with LGBTQ+ characters and narratives are selected to comprise the corpus, with Critical Discourse Analysis as the main Methodology. …

Micro- and nanoscale features of insect cuticle and their impacts on wetting, friction, and optical properties
… other organisms with diffraction-grating induced iridescence tend to inhabit similar moist microhabitats and share burrowing behaviors. It has been hypothesized that these gratings effect friction and allow beetles to more easily move through substrates and that iridescence is a byproduct of this …

Tailoring the angular and spectral reflectance characteristics of color-dynamic films by modifying their photonic texture and topcoat roughness
… space of different appearances, including strong iridescence, color constancy with collimated light sources at small angles of incidence, pure and muted colors, and specular and highly diffuse reflections.

Photonic Properties of Liquid Crystalline Hydroxypropyl Cellulose in the Solid-state
… obtained and instead of the typical metallic iridescence associated with HPC mesophases, these films appeared matte and angular independent. Secondly, a functionalised HPC polymer was exploited as an ink to achieve direct 3D printing of photonic structures, which colour could be tuned by …

Design and Optimization of Moldable Microstructures for Structural Color Generation
… are capable of producing simpler color and iridescence, without the manufacturing difficulties. These shapes are also capable of being embossed or molded into a single material, allowing for many mass production opportunities. To investigate the optical properties of these simple moldable …

Colloidal Self-Assembly: Particle Synthesis, Functionalisation and Applications
… photonic crystals which, rather than showing iridescence, displayed strong single colour reflectance along with high transmittance, with the reflection colour varying with interparticle distance. Jumping back to colloidal assembly via DNA, rod-sphere structures made from DNA-coated gold …

Polymer hydrogel nanoparticles and their networks
… nanoparticle networks that display a striking iridescence like precious opal but are soft and flexible like gelatin. This is in contrast to previous colored hydrogels, which were created either by adding dyes or fluorescent, or by organic solvent or by embedding a colloidal crystal array of …

Testing the Urban Dulling Hypothesis in an Iridescent Passerine Bird
… urban starlings to shape mate choice. Instead, iridescence in starlings may be a beneficial trait as this plumage type could be more resilient to the various overly abundant plumage degrading mechanisms common to cities. Future research studies should explore how exactly iridescent plumage …

Radiation in the genus Amazilia: A comparative approach to understanding the diversification of hummingbirds.
… upon the mating system, display type, plumage iridescence, and tail shape. Traditionally, sexual size dimorphism has been correlated with mating systems. However, lekking was not correlated with size or plumage dimorphic when phylogenetic history was considered. I interpret the observed …

Physical phenomena of thin surface layers
… energy source and an environmental signal. Blue iridescence occurs in a wide range of plant species, suggesting that it has some adaptive benefit. These are considered and discussed.

On the molecular pathways supporting the development of structurally coloured cuticle in Hibiscus trionum
… in an angle dependant manner (also known as iridescence). Further observations of the cuticle showed the presence of nano-scaled striations acting as a grating like surface responsible for the diffraction of light. Computational modelling, and existing knowledge in material physics, suggests …

Physically Realistic Rendering of Complex Materials Using Wave optics
… and in the steam coming from a cup of hot tea. Iridescence on the water surface is caused by droplets levitating above the surface, and interference between light scattered by drops and reflected by the water surface, known as Quetelet scattering, is essential to producing the color. We propose …

Structural colour from a helicoidal cellulose architecture in the secondary cell wall: Optical properties, cell wall composition, structure and morphology of components, and their assembly and interactions.
Structural colours are produced by constructive interference of light scattered from periodically arranged interfaces within nanostructured materials. A common strategy of plants to achieve structural coloration consists of assembling cellulose microfibrils into helicoidal structures. Examples of …
