2. 1. Generation of the Bound Entangled Smolin State and Entanglement Witnesses for Low-Dimensional Unitary Invariant States

   University essay from Uppsala universitet/Teoretisk fysik

   Author : Emil Nordling; [2010]
   Keywords : quantum mechanics; quantum information science; entanglement; photonics; Smolin state; unitary invariant states;

   Abstract : Quantum entanglement is employed as a resource throughout quantum information science. However, before entanglement can be put to intelligent use, the issues of its production and detection must be considered. This thesis proposes four schemes for producing the bound entangled Smolin state. READ MORE

4. 2. Does arbuscular mycorrhiza symbiosis increase the capacity or the efficiency of the photosynthetic apparatus in the model legume Medicago truncatula?

   University essay from Linköpings universitet/Linköpings universitet/Linköpings universitetMolekylär genetik

   Author : Ateeq ur Rehman; [2010]
   Keywords : Medicago truncatula; Arbuscular mycorrhiza symbiosis; Photosynthesis; Chlorophyll fluorescence; Oxygen evolution; Lhcb1 and Lhcb2 proteins content; phosphor uptake; Reproductive fitness;

   Abstract : The Arbuscular mycorrhiza (AM) is an endosymbiont of higher plant roots. Most land plants and cultivated crops are concerned to AM symbiosis. This endosymbiosis is based on the mutual exchange of nutrients between plant and fungus. Therefore, AM symbiosis leads to an increased demand for photosynthetic products. READ MORE

6. 4. Synthesis and characterisation of ZnO nanoparticles.An experimental investigation of some of their size dependent quantum effects

   University essay from Uppsala universitet/Institutionen för materialkemi

   Author : T. Jesper Jacobsson; [2010]
   Keywords : ZnO; nanoparticles; quantum dots; Sol-gel; Time resolved UV-Vis spectroscopy; fluorescence; Raman; Phonon spectrum; Synthesis; XRD;

   Abstract : ZnO nanoparticles in the size range 2.5–7 nm have been synthesised by a wet chemical method where ZnO particles were grown in basic zinc acetate solution. The optical band gap increases when the size of the particles decreases. READ MORE

7. 5. Surface Modification of CdSe(ZnS) quantum dots for biomedical applications

   University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

   Author : Ann Winzell; [2010]
   Keywords : Quantum dots; surface modification; XPS;

   Abstract : Quantum dots are inorganic nanocrystals of semiconductor metals that have unique light emitting properties. Due to their tunable and narrow emission profile, broad absorption spectra, resistance to photobleaching and high level of brightness they have emerged as inorganic fluorophores and numerous applicabilities for in vitro, in situ as well as in vivo studies are present.
