Siden viser de projekter som blev valgt i foråret 2013. Der vil være et resumé for hvert projekt, som er skrevet i begyndelsen af projektet.
The focus of the project is design, development and optimization of thiol-ene waveguides used for detection of simple fluorescent proteins. The goal is to use a thin metal coating (gold to begin with) to produce a plasmon effect, which in turn can enhance intensity of the fluorescence and therefore the signal to noise ratio. To achieve the desired effect it is required to optimize many different parameters and factors. The factors could be: Annealing temperature, waveguide design, thiol-ene composition, fluoresence molecule, excitation wavelength, metal coating methods, the metal itself and the production method of the waveguides(milling, nickel form etc.).
Resume:There are three main problems when creating single photon sources in nano wires: The light needs propagate in the first guided mode, such that the light can be directed into a lens. Secondly, by symmetry, the light can either propagate forward or backward, which means that reflection is required to ensure that all of the light travels in the correct direction. Lastly, the type of tapering used in the nano wire influences be behaviour of the light at the end of the wire. In this project, we will take a theoretical approach to examine these problems.
The aim of the project is to measure fluxes of possible new X-ray sources (black holes and neutron stars) as well as to improve the measurement of positions of little-known sources. We will exploit real data from the international space observatory JEM-X, aboard the ESA satellite INTEGRAL. Sky images will be obtained and light curves and energy distribution of the X-ray emission will be produced from observations to study the time variations of the source X-ray emission and to further investigate the physical properties of the sources. Furthermore, we hope to discover new celestial X-ray sources and to study their observational properties.
