Abstract:
In the present research the commercial cotton textile was modified by the sol-gel method to evaluate sol-gel technology suitability for cotton textile modification. The nanosol was deposited on the cotton textile by dipping process. The evaluation of the dipping process for thin zinc oxide coating deposition was made. The sol-gel method for nanosol preparation used in this research to implement zinc oxide coating on the fabric surface is a simple process that can be easily transferred to the textile industry, nanosol can be also applied by conventional coatings techniques used in the text

The number of engineered nanomaterials (ENMs) being exploited commercially is growing rapidly, due to the novel properties of ENMs. Clearly, it is important to understand and ameliorate any risks to health or the environment posed by the presence of ENMs. However, there still exists a critical gap in the literature on the (eco)toxicological properties of ENMs and the particular characteristics that influence their toxic effects. Given their increasing industrial and technological use, it is important to assess their potential health and environmental impacts in a time and cost effective manner

With the rapid down-sizing of electronic and photonic device dimensions, understanding of the carrier transportation in nanoscale materials becomes crucial. In this thesis, we report the ultrafast carrier dynamics of vertically aligned InN nanorod arrays grown by molecular-beam epitaxy on

Differing proton concentrations is believed to cause structural changes in the lipopeptide surfactin used to stabilize the gold nanoparticles in aqueous solution, the effects of which on the morpHology of the nanoparticles were investigated. Synthesis of gold nanoparticles by borohydrate reduction was performed at three pH levels (pH 5, 7 and 9) and two different temperatures, and the nanoparticles were characterized by UV–visible spectro

GNPs became a part of the polymer main chain, and hence can be dispersed uniformly in the nanocomposites. Because the previous literatures which used blend method to prepare the polymer-nanogold composites were the low content of GNPs, in this study the chemical bonding between the polymers and GNPs were formed to prepare the composites of high content of GNPs.

Abstract:
A spectrally integrated response method is proposed for analyzing transmission data from nanohole array sensors. This method increases the sensitivity by reducing noise and taking more information from the spectrum for bulk and surface sensing. Results from both real experiments and idealized simulations are presented. Comparison with two other methods- peak transmission wavelength shift and a normalized difference integrated response method are shown. This method shows improved sensing performance which can be exploited in future. Further improvement in sensing using nanohole arrays is ex

Firstly, directly grown laterlly ZnO nanorods on the Au electrode. Secondly, Using the different annealing time for Au electrode, the effect of pre-annealing process on suppressing vertical ZnO nanorods is systematically investigated by atomic force microscopy and scanning electron microscopy.

First, MUD coated-GNPs was synthesized by the chemical reduced method. The shell of the prepared GNPs contains -OH group that can react with the -NCO group of diisocyanate, and hence GNPs can disperse uniformly in the nanocomposites. Polyurethane-nanogold nanocomposites are prepared by linear and nonlinear polyol, respectively.

Since one-dimensional nano-material has unique nano structure, they are very good in sensor, field-emitter and photoelectric component applications.

Au nanorods are synthesized by electrochemical methods with an aid of co-surfactants. An thiolated silica shell layer is coated on each Au nanorod and it serves as a substrate for immobilizing foreign 0D nanoparticles.
