Tuning intermolecular attraction to create polar order and one-dimensional nanostructures on surfaces.

Molecular interactions in one-dimensional organic nanostructures.

Intermolecular interactions involving pi-pi interaction and hydrogen bonding are used to create one-dimensional molecular nanostructures of hexasubstituted aromatics. Site-selective steady state fluorescence, time-resolved fluorescence, scanning electron microscopy, and atomic force microscopy measurements detail the intermolecular interactions that drive the aromatic molecules to self-assemble...

Modeling of the intermolecular Force-Induced Adhesion in Freestanding Nanostructures Made of Nano-beams

Among the intermolecular interactions, the Casimir and van der Waals forces are the most important forces that highly affect the behavior of nanostructures. This paper studies the effect of such forces on the adhesion of cantilever freestanding nanostructures. The nanostructures are made of a freestanding nano-beam which is suspended between two upper and lower conductive surfaces. The linear s...

Computational study of three dimensional potential energy surfaces in intermolecular hydrogen bonding of cis-urocanic acid

Protecting Surfaces Using One-Dimensional Nanostructures

Ultraviolet waves, because of their short wavelength, have a high energy and considerable damaging effects on surfaces. Protection against ultraviolet radiations is one of the finishing treatments done on surfaces exposed to sunlight. The importance of this issue in relation to human health, due to complications such as skin burns and cancer, is doubled. Up t...

Surface Polarity and Shape-Controlled Synthesis of ZnO Nanostructures on GaN Thin Films Based on Catalyst-Free Metalorganic Vapor Phase Epitaxy

With the rapid developments in nanotechnology, there has been tremendous interest in ZnO-related nanomaterials because ZnO is a wide band-gap semiconductor and a piezoelectric oxide. As a result, it is useful for optoelectronics, transparent electronics, sensors, and transducers. ZnO crystals have a noncentral symmetric wurtzite structure and are composed of close packed O and Zn2þ layers piled...
