Abstract:

The development of metrological and analytical methods for the detection and quantification of nanomaterials (NMs) has been identified as one of the most urgent and important research priorities to advance nanotechnology. Several nanometrics such as mass, number and surface area are currently under scrutiny by nanotechnologists in order to identify the most appropriate metrics to express the hazard of NMs and therefore to perform risk assessments. Currently, NM mass concentration is almost universally used as a metric because of challenges with analytical measurements, while the mass concentra

Abstract:

One of the promising methods to extend the liquid crystal (LC) functionality is introduction of the nanoparticles. Thus, nanoparticles of superionic conductors with argyrodyte structure, in particular Cu6PS5I, can help to extend functional properties of LC. They are characterized by high electrical conductivity as well as ferroelastic and nonlinear optical properties. Therefore, the aim of this work was to study the influence of Cu6PS5I nanoparticles on the electrical conductivity of 6СВ and 6СНВТ liquid crystals.

The emergence of nanotechnology has increased the concern of exposure to nanoparticles through inhalation. Studies have examined the performance of filtering facepiece respirators against engineered nanoparticles.

Abstract:

In the last years, the progressive miniaturization of magnetic storage devices has imposed the necessity to understand how the physical properties are modi- ed with respect to the bulk when the dimensions are reduced at the nanometric scale. For this reason an accurate method of preparation and characterization of nanostructures is extremely important. This work focuses on the magnetic and transport properties of cluster-assembled nanostructures, namely cobalt nanoparticles embedded in copper matrices.

Abstract:

The rise of antimicrobial resistance demands the development of more rapid screening methods for the detection of antimicrobial resistance in clinical samples to both give the patient the proper treatment and expedite the treatment of patients. Cerium oxide nanoparticles may serve a useful role in diagnostics due to their ability to exist in a mixed valence state and act as either oxidizing agents or reducing agents. Considering that cerium oxide nanoparticles have been shown to shift in absorbance upon oxidation, a useful method of antimicrobial resistance detection could be based on the oxid

Without fully understanding phase, formation, and other important competing effects of the synthesis parameters on the final structure, the maximum potential of these nanostructures cannot be obtained.

Abstract:

The objective of this study was to determine how Al2O3 nanoparticle concentration affected the specific heat, heat of fusion, melting point, thermal diffusivity and thermal conductivity of Alumina-Nitrate nanofluids. Al2O3 nanoparticles were dispersed in a eutectic of sodium nitrate and potassium nitrate (60:40 for mole fraction) to create nanofluids using a hot plate evaporation method and an air dryer method. The nominal Al2O3 (alumina) mass fraction was between 0 and 2%, and was determined as the ratio of the mass of Al2O3 nanoparticles to the total mass of the nanofluid. After the prepara

Commonly used methods for measurement of cGMP are the competitive enzyme immunoassay (EIA) and radioimmunoassay. However, the protocol for EIA is tedious and the radioimmunoassay is unsafe for personnel. To overcome the above disadvantages, we developed an optical fiber modified with a self-assembled monolayer of nano-gold particles conjugated with anti-cGMP ant

When two metal nanoparticles get very close, they will couple each other. There will be an electric field enhancement between two particles, called a hot spot. In this experiment, the silver nanoparticle solution were prepared by chemical reduction method. After that, the silver nanoparticles were surface-modified with 8-mercapto-octanoic acid (MOA) molecules. Finally, the modified silver nanoparticles were arran

碩士<br>國立交通大學<br>應用化學系所<br>92<br>Gold nanoparticles are used widely in various fields because of their extremely small size, high specific surface areas, and ease of chemical modification. Gold nanoparticles prepared from the reduction of tetrachloroaurate by using trisodium citrate as the reducing agent have negatively charged surfaces because of the attachments of anions such as citrate ions onto their AuI shell surfaces. Based on this characteristic, this thesis demonstrates that gold nanoparticle-based probes are capable of trapping net positively charged analytes from sample solutions. In
