DYNAMIC COMPOSITES. "Butterfly wings, like exoskeletons of most insects, represent a form of biological composite made of chitin fibers in a protein matrix. Similar to many other polysaccharide-based biopolymers, chitin is reported to be piezoelectric." http://digitalcommons.unl.edu/cgi/viewcontent.cgi?article=1041&context=physicsgruverman View in LinkedIn

ELECTROMECHANICAL BONE. "The biological significance of piezoelectricity in bone is that it suggests correlation between bone properties and its functionality. Subsequently, the electromechanical behavior of bone attracted significant attention due to possible clinical application of electrical stimulation to bone growth and repair." https://lnkd.in/ejQXn-P View in LinkedIn

CHIRAL ASYMMETRIES. "In recent years, even piezoelectric, pyroelectric, and ferroelectric effects in biological materials are the subject of investigations. Pasteur was probably the first to suggest over 100 years ago that biological systems have chiralic dissymmetric properties and that these properties are important for the functioning of biological systems." https://lnkd.in/dHfzDYk View in LinkedIn

"STRUCTURAL COLOR in flowers, such as the iridescence exhibited by hibiscus trionum and tulipa kauffmanniana petals is determined by surface diffraction gratings that consist of ordered striations or ridges...cellulosic CLCs (cellulose chiral liquid crystals) are responsible for plant surface nanostructures and iridescent colors." http://www.sciencedirect.com/science/article/pii/S2215038214000077 View in LinkedIn

CELLULOSE CHIRAL LIQUID CRYSTALS (CLC). "Biological materials, such as DNA in human cells, cellulose in plant cell walls, chitin in arthropod' cuticles and collagen in human compact bones, exhibit Bouligand's twisted plywood architecture, which is that of cholesteric liquid crystal." https://lnkd.in/dyyFFsB View in LinkedIn

“CHIRALITY IN NATURE is ubiquitous in exquisite examples wherever you look, be it at the molecular, cellular, or organismic level. However, in a biomimetic quest for new materials with new properties, a stumbling block is often the introduction of chirality into a synthetic system, to try to mimick the 60 biomineral materials made by millions of species in nature.” https://lnkd.in/dCa_nDw View in LinkedIn

THz TUNING. "Split ring resonators show a capability for tuning across the terahertz regime. Furthermore, the repeating structure made up the constituent materials follows the same strategy of averaging the electromagnetic field as it manipulates and transmits the terahertz radiation." https://en.m.wikipedia.org/wiki/Terahertz_metamaterials View in LinkedIn

CASIMIR EFFECT. “A vacuum in space is full of electromagnetic energy, and is affected by the material around it, especially at small volumes. This is a source of an enormous amount of energy that could possibly be harnessed.” http://www.scientificamerican.com/article/what-is-the-casimir-effec/ View in LinkedIn
