Colloidal Assembly of Plasmonic Superstructures: New Approaches for Sensing

Wang, Ruosong 16 May 2022 (has links)
Noble metal nanoparticles have attracted the attentions of many researchers because of unique plasmonic properties since their discovery and successful preparation. Nanocluster formed by the assembly of noble metal nanoparticles can exhibit plasmonic characteristics beyond those of individual nanoparticles, which can be tuned, to a large extent, by adjusting the size, shape, chemical composition, and arrangement of individual nanoparticles. Usually nanocluster with special ordered structures is called as superstructure, which can be designed for different purposes through various methods. Colloidal assembly as a cost-efficient approach can be widely used for fabrication of plasmonic superstructure in solution media. As an introduction of background, the developments of plasmonic nanoparticles and nanoclusters have been discussed in the aspects of their LSPR properties, surface modification for colloidal assembly, and sensing applications. Both colorimetry and SERS detection based on plasmonic assemblies have been presented as effective sensing methods, which are also the motivations for the main experiments in this thesis. As a proof-of-motivation, the different kinds of thiol-terminated PEG assisted hybrid gold nanoparticles have been applied for the protein colorimetric detections based on the specific interaction between heparin and proteins with different surface affinities. In addition, PEG-assisted core/satellite superstructures with various polymer thickness as SERS platform have been demonstrated for trace sensing of specific target molecules in solution. Especially, the method to differentiate between the radiative and non-radiative contributions of plasmonic superstructure has been proposed using diffuse reflectance spectroscopy, which provides a favorable selection and design of best candidates for specific application scenarios. Finally, the concept of NIR-II SERS using biological transparency window has been introduced including the fundamental requirements, which proposed a future experiment to fabricate suitable superstructures for potential biomedical applications with high penetration depth at low laser powers. Generally speaking, the central focus of this thesis is the effect of polymer modification on the structures and properties of plasmonic superstructure and its sensing application. The main research efforts are divided into three parts: (I) investigate the topological effect of polymer structure parameters on plasmonic properties for colorimetric analytics; (II) investigate the impact of interparticle spacing within the assemblies and polymer dimensions on the SERS activity; (III) investigate the plasmonic properties tailoring of superstructures as well as the contribution of scattering (radiative) and absorption (non-radiative), i.e. light-to-heat conversion, within the ensemble optical response.

Structure and morphology of ultrathin iron and iron oxide films on Ag(001)

Bruns, Daniel 21 November 2012 (has links)
This work investigates the initial growth of iron and iron oxides on Ag(001). Surface structure and morphology of both post deposition annealed Fe films (in UHV and O2 atmosphere) as well as reactive grown iron oxide films will be analyzed in detail by low energy electron diffraction (LEED) and scanning tunneling microscopy (STM). The stoichiometry at the surface of the iron oxide films will be determined by X-ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy (AES). The main focus of this work is to shed light on the question whether the growth of iron oxide films on Ag(001) is accompanied by the formation of strain reducing dislocation networks, or superstructures as found for other metal substrates in former studies. Here, we will distinguish between Fe films which were post deposition annealed in a thin O2 atmosphere and reactively grown iron oxide films.

Rekonstrukce železniční stanice Svitavy / Reconstruction of Railway Station Svitavy

Marek, Josef January 2022 (has links)
The goal of this thesis was to design the reconstruction of the railway station Svitavy. The line speed was rised from the current value to 160 km·h-1. New platforms were designed, therefore the railway substructure and the drainage were adjusted accordingly. Also, the effective length of the main tracks was extended to 740 m.
