"SYMMETRY is a crucial ingredient in the self-assembly of nanostructures with novel optical, electronic, magnetic, or thermal functionality...many new physical properties that are desirable to access depend on breaking this symmetry to introduce higher-order complexity, which has proved difficult. On the other hand, in naturally occurring photonic crystals, such anisotropic structures are widely prevalent." http://www.np.phy.cam.ac.uk/uploads/2010/prl10-stretchtune-opalopt.pdf View in LinkedIn

ASYMMETRIC UNIVERSE. "Particle physics is left-handed in its own way. The electrons emitted during certain radioactive decays all spin in a left-handed fashion. The force that controls these decays, the so-called weak force, is thought to have an influence on the formation of biomolecules." http://www.astrobio.net/news-exclusive/how-life-shatters-chemistrys-mirror/ View in LinkedIn

Polarized light is changed from uniform and symmetric to asymmetric light that can be used to generate information, or a signal, and do work. Liquid crystals (LCDs) are photoswitchable chiral switches composed of two physical phases. This is extreme Biomimicry. https://lnkd.in/eEcTq6T View in LinkedIn

RULE BREAKING. "Stretching ordered polymer opals in different directions transforms the fcc photonic crystal into correspondingly distorted monoclinic lattices. This breaks the conventional selection rules for scattering from the crystal planes, yielding extra multiply scattered colors when the phase-breaking stretch is in specific directions." http://www.np.phy.cam.ac.uk/uploads/2010/prl10-stretchtune-opalopt.pdf View in LinkedIn

PIZOELECTRIC TRANSDUCERS. "The piezoelectric effect in polymers is usually explained in terms of the uniaxial orientation of the polymer crystallites and the classical piezoelectric property of these crystallites. Polarization caused by stress gradient seems to be necessary to the understanding of the geometrical relationship between stress and polarization." http://www.sciencedirect.com/science/article/pii/0041624X68901327 View in LinkedIn
