“Catalysis” is a field of science that relates to the increase of the rate of a chemicalreaction through the involvement of an additional substance, known as “catalyst”,which acts without being consumed. Among all known types, heterogeneous catalysis, where the catalyst is in different phase than the reactants, plays a pivotal role in the sustainable development of the modern society with its domiSupported gold nanoparticles are emerging as an important class of catalysts for various organic transformations due to their tunable properties. This thesis embraces the fundamental studies of supported gold nanoparticles for different organic reactions from the viewpoint of understanding the role of synthesis methods, nature of carriers, and addition of second metal on the properties and functio

Accurate diagnosis, characterization, and quantification of myocardial infarction (MI) is essential to assess the impact of therapy and to aid in predicting prognosis of patients with ischemic heart disease. Delayed contrast-enhanced magnetic resonance (DE-MR) imaging has the potential of being the gold standard for quantification of MI. It has also been useful in correlating electrocardiography a

In the western world, approximately 50% of all cancer patients receive radiotherapy alone or in combination with surgery or chemotherapy. Image-guided radiotherapy (IGRT) has in recent years been introduced to enhance precision of the delivery of radiation dose to tumor tissue. Fiducial markers are often inserted inside the tumor to improve IGRT precision and to enable monitoring of the tumor posi

The high surface-to-volume ratio of nanoparticles (NPs) makes them an interesting source for scientific research. How interfacial energies interplay between such a small structure and a solid bulk surface, are important because of the versatile applications NPs regard. In this thesis, a convenient and reliable method for interfacial energy determination was investigated. The interfacial energies

Streptococcus bovis/Streptococcus equinus complex (SBSEC) is a common cause of infective endocarditis (IE). For IE-pathogens, the capacity to activate and aggregate platelets is believed to be an important virulence mechanism. While the interactions between bacteria and platelets have been described in detail for many Gram-positive pathogens, little research has been carried out with SBSEC in this

Manipulating the light polarization properties of gold nanoparticle aggregates can facilitate their applications in sensing and imaging. However, control of the intrinsic light polarization on demand at the nanoscale is hindered by the lack of a fundamental understanding of the structure-dependent plasmon coupling in the aggregates. Here, the polarization properties of intrinsic photoluminescence

This project is a collaboration between Lund University Historical Museum, Lund University Library and various departments of the university. The team members represent the fields of history, archaeology, Latin language studies, anthropology, museology, geology, botany and zoology. This combined expertise is necessary to tackle the diverse material and questions posed in the project. Per Karsten,

The authors present in this paper how the extended Mie theory can be used to translate not only end-point data but also temporal variations of extinction peak-position changes, peak(t), into absolute mass uptake, (t), upon biomacromolecule binding to localized surface plasmon resonance (SPR) active nanoparticles (NPs). The theoretical analysis is applied on a novel sensor template composed of a th

We present a method to produce small pitch gratings for X-ray interferometric imaging applications, allowing the phase sensitivity to be increased and/or the length of the laboratory setup to be minimized. The method is based on fabrication of high aspect ratio silicon microstructures using deep reactive ion etching (Bosch technique) of dense grating arrays and followed by conformal electroplating

This paper presents a study of the physical limitations for radio frequency absorption in gold nanoparticle (GNP) suspensions. A spherical geometry is considered consisting of a spherical suspension of colloidal GNPs characterized as an arbitrary passive dielectric material which is immersed in an arbitrary lossy medium. A relative heating coefficient and a corresponding optimal near field excitat

We demonstrate how water-soluble gold nanoparticles prepared by the citrate reduction method can be functionalized with 11-azidoundecane-1-thiol in a single-step procedure, which combines phase transfer and ligand exchange. The advantages of our method include high reproducibility, low cost of gold nanoparticle production, and rapid and clean ligand exchange, with minimal intermediate steps and no

Mörk materia har funnits sedan tidernas begynnelse, från den Stora Smällen. Under Universums första hundratals miljoner år var tyngdkraften från den mörka materian så kraftfull att den drog till sig den vanliga materian, som muskler till revben, och formade gigantiska strukturer. De första galaxerna växte där dessa strängar möttes.Galaxer kolliderade med andra galaxer, och slogs samman för att
