Tropical Morpho butterfl ies are known for their iridescence. [ 1 ] Extensive research has been dedicated to analyzing the nanoscale architecture of Morpho butterfl y wings to understand their brilliant blue or white–purple iridescence The wing scales of Morpho butterfl ies contain 3D nanostructures that produce blue iridescent colors. Incident light is diffracted from multilayered nanostructur...

A novel type of 1D nanostructure with characteristics between those of a solid nanowire and a hollow nanotube, i.e. a peashell-like nanostructure comprising a 1D wire with periodically embedded hollow nanobubbles, is presented for the first time; as an example, MgO peashell-like nanostructures exhibit extraordinary dielectric and magnetization properties.

A simple procedure for introducing functional exogenous membrane-bound proteins to viable cells encapsulated within a lipid templated silica nanostructure is described. In one method, bacteriorhodopsin (bR) was added directly to a Saccharomyces cerevisiae solution along with short zwitterionic diacylphosphatidylcholines (diC(6) PC) and mixed with equal volumes of a sol precursor solution. Alter...

Title of Document: FAILURE MECHANICS OF FUNCTIONAL NANOSTRUCTURES IN ADVANCED TECHNOLOGIES Zheng Jia, Doctor of Philosophy, 2014 Directed By: Associate Professor Teng Li, Department of Mechanical Engineering The past decade has seen a surge of interest in developing novel functional nanostructures to enable advanced technologies, such as flexible electronics and high performance lithium-ion bat...

A novel amperometric glucose biosensor was fabricated by layer-by-layer self-assembly of gold nanorods (AuNRs) and glucose oxidase (GOD) onto single-walled carbon nanotubes (SWCNTs)-functionalized three-dimensional sol-gel matrix. A thiolated aqueous silica sol containing SWCNTs was first assembled on the surface of a cleaned Au electrode, and then the alternate self-assembly of AuNRs and GOD w...

Structures of the mesophases of five members of the 4-n-alkyl-4'-cyanobiphenyl homologous series (4-n-butyl-4'-cyanobiphenyl to 4-n-octyl-4'-cyanobiphenyl) doped with milled BaTiO_{3} nanoparticles were investigated by x-ray scattering. Clear solutions of each of the 4-n-alkyl-4'-cyanobiphenyls were first prepared in n-heptane and then doped with an n-heptane/nanoparticle dispersion, which led ...

In this work, we applied advanced Synchrotron Radiation (SR) induced techniques to the study of the chemisorption of the Self Assembling Peptide EAbuK16, i.e., H-Abu-Glu-Abu-Glu-Abu-Lys-Abu-Lys-Abu-Glu-Abu-Glu-Abu-Lys-Abu-Lys-NH₂ that is able to spontaneously aggregate in anti-parallel β-sheet conformation, onto annealed Ti25Nb10Zr alloy surfaces. This synthetic amphiphilic oligopeptide is a go...

Introduction Nanomaterials can be broadly defined as the use materials whose components exhibit significantly changed properties when control is gained at the atomic, molecular, and supramolecular levels [1]. Although various definitions are attached to the word “nanomaterial” by different experts, the commonly accepted concept refers nanomaterials as that material with the basic structural uni...
