"STRUCTURAL COLORS are mainly based on several elementary optical processes including thin-layer interference, diffraction grating, light scattering, photonic crystals ... However, in nature, these processes are somehow mixed together to produce complex optical phenomena." These are responsible for peacock feather colors. http://iopscience.iop.org/0034-4885/71/7/076401 View in LinkedIn

NEWTON'S 1704 "TREATISE ON OPTICS". "Sir Isaac Newton, the 17th- and 18th-century British mathematician and physicist, was among the first to suggest that tiny, layered structures were responsible for producing color in peacock feathers, and other iridescent insects and birds." http://news.nationalgeographic.com/news/2003/10/1016_031017_peacockcolors.html View in LinkedIn

SEMICONDUCTOR REVOLUTION. "Semiconductors have had a monumental impact on our society. You find semiconductors at the heart of microprocessor chips as well as transistors. Anything that's computerized or uses radio waves depends on semiconductors." http://electronics.howstuffworks.com/diode.htm View in LinkedIn

FRAGMENT IN NATURE: a pause in the current tobacco theme to examine briefly something beautiful and interesting from nature. In this case it is peacock feathers and the phenomenon of structural color. Very coincidentally, these phenomena anticipate the design of semiconductors, which changed our modern world.

IRIDESCENT COLOR. "Both the submicron regular structure of melanin granules and macroscopic shape/ configuration of barbules contribute to the essential part of the iridescent color in peacock feathers." https://lnkd.in/dyZyb_e View in LinkedIn

SMOKELESS TOBACCO (ST): "There was sufficient evidence that ST use is carcinogenic to humans, with sufficient evidence that "ST causes cancers of the oral cavity and pancreas ... ST use is not associated with statistically significant elevated RRs for heart attack ... ST product use is associated with a slight increase in the risk of stroke mortality." http://www.harmreductionjournal.com/content/8/1/19 View in LinkedIn

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
