IRIDESCENT PEACOCK FEATHERS. "Peacock feather is one of the most well-known examples for the structural color ... melanin granules form the submicron periodic structure with the periodicity comparable with the wavelength of visible light and are thought to be the origin of optical interference." https://lnkd.in/dyZyb_e View in LinkedIn

e-CIGARETTES. "Although some are associated with significant health harms, including increased risks of nasal, oral or gastrointestinal cancer, none causes lung cancer or COPD and all are substantially less hazardous than smoked tobacco." https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/311887/Ecigarettes_report.pdf View in LinkedIn

"COLORATION STRATEGIES in peacock feathers are very ingenious and simple: controlling the lattice constant and the number of periods in the photonic-crystal structure. Varying the lattice constant produces diversified colors. The reduction of the number of periods brings additional colors, causing mixed coloration." https://lnkd.in/d6zYcj2 View in LinkedIn

PUBLIC HEALTH POLICY DROVE CHANGES. Transnational tobacco companies' "adoption and subsequent use of the term harm reduction occurred in direct response to the public health agenda ... The ‘Clearing the Smoke’ study by IOM appears to have been pivotal in shaping the tobacco industry discourse on harm reduction." https://lnkd.in/dvWpVz3 View in LinkedIn

PEACOCK FEATHER COLOR LATTICE. "The cortex in differently colored barbules, which contains a 2D photonic-crystal structure, is responsible for coloration." https://lnkd.in/d6zYcj2 View in LinkedIn

EVOLUTION made peacock feathers' molecular structures similar to those used by the semiconductor revolution, that have transformed modern life. Peacock feathers gate light (photons), while doped semiconductors gate electrons. " "In: Nano-society: Pushing the Boundaries of Technology, (Section 4.5), By Michael Berger View in LinkedIn

POWERFUL GATES. Photonic crystals "makes it possible to control light with amazing facility and produce effects that are impossible with conventional optics." " "In: Nano-society: Pushing the Boundaries of Technology, (Section 4.5), By Michael Berger View in LinkedIn

PEACOCK PHOTONIC CRYSTALS. "By creating periodic structures out of materials that differ in their dielectric constants, it becomes possible to guide the flow of light through photonic crystals ... Similar to how electrons are directed through doped regions of semiconductors." https://lnkd.in/dhTvJv8 View in LinkedIn

PHOTONIC CRYSTALS ACT LIKE SEMICONDUCTORS. "Photonic crystals ... are similar to semiconductors, except that the electrons are replaced by photons (i.e., light)." https://lnkd.in/dhTvJv8 View in LinkedIn

PEACOCK FEATHER LIGHT GATES, "By varying the lattice constant and the number of periods in the photonic crystal structure, peacock feathers provide several 2D photonic crystal structures with different colors. The ordered melanin arrays within peacock feathers are ... natural photonic crystals that have the ability of controlling visible light." https://lnkd.in/dhTvJv8 View in LinkedIn
