Temperature Tunability of Dielectric/ Liquid Crystal / Dielectric Photonic Crystal Structures

Recently, photonic crystals doped with liquid crystal (LC) material havegained much research interest. In this article new ternary one-dimensional photoniccrystal introduced and studied. The liquid crystal layer of 5CB and 5PCH is sandwichedby two dielectric layers. For the first time, we use four structures SiO2/UCF35/CaF2,SiO2/5CB/CaF2, NFK51/UCF35/NPSK53 and NFK51/5CB/NPSK53. The effect ofte...

Temperature-responsive protein pores.

We describe temperature-responsive protein pores containing single elastin-like polypeptide (ELP) loops. The ELP loops were placed within the cavity of the lumen of the alpha-hemolysin (alphaHL) pore, a heptamer of known crystal structure. The cavity is roughly spherical with a molecular surface volume of about 39,500 A3. In an applied potential, the wild-type alphaHL pore remained open for lon...

Force Spectroscopy of Stimulus-Responsive Polymers

Interactions on the level of single macromolecules become exceedingly important as we strive to understand and harness the properties of nanoscale systems. Specifically, we are interested in the nanomechanical behavior of stimulus-responsive polymers that display a strong volume transition which can be exploited for force generation. For example, the genetically encodable synthesis of stimulus ...

Ferroelastic domain wall orientations in the ( NH 4 ) 3 H ( SeO 4 ) 2 crystal

Experimental and theoretical studies of the ferroelastic domain structure of the (NH 4) 3 H(SeO 4) 2 crystal in phases III and IV are performed. Using the refined structural data the orientations of Wand W 0-type domain walls, as well as the temperature evolution of the domain structure are investigated. It is shown that in spite of the fact that the room temperature phase III has a triclinic s...
