  1. 6. Development of an Upconverting Nanoparticles Quantum Yield Measurement System

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Meng Li; [2016]
    Keywords : UCNPs; upconverting nanoparticles; QY; quantum yield; fluorescence; luminescence; Physics and Astronomy;

    Abstract : Fluorescence imaging is a growing biomedical technique; it can be used to localize the luminescent biomarkers inside the tissue. Lanthanide-doped upconverting nanoparticles (UCNPs) are promising luminescent probes for multiple applications in biophotonics. They allow acquiring autofluorescence-free recordings with high spatial resolution. READ MORE

  3. 7. Modeling the Effects of Strain in Multiferroic Manganese Perovskites

    University essay from KTH/Materialfysik, MF

    Author : Markus Silberstein Hont; [2015]
    Keywords : Condensed matter physics; multiferroics; magnetism; spin modeling; computational physics; Kondenserade materiens fysik; multiferroiska material; magnetism; spinnmodellering; beräkningsfysik;

    Abstract : The effects of strain on the magnetic phases in perovskites are of interest in the highly active research field of multiferroics. A Monte Carlo program is written to investigate the influence of strain on the low– temperature magnetic phase diagram of the manganese perovskites, RMnO3, where R is a cation in the lanthanide series.

  4. 8. Analytical model of mass transfer through supported liquid membranes

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Jonas Lantto; [2015]
    Keywords : supported liquid membranes; lanthanide extraction; analytical solution; boundary layer resistance; coupled counter-transport; Immobiliserade vätskemembran; lantanidextraktion; analytisk lösning; gränsskiktsmotstånd; kopplad mot-transport;

    Abstract : This report details the development and validation of a model for the simulation of supported liquid membrane processes, as applied to the extraction of lanthanides. Supported liquid membranes are systems where two phases, usually aqueous, are separated by a third phase, typically organic, which acts as a membrane, in order to separate solutes from one phase to the other.

  5. 9. Experimental Studies of Synthesis and Adsorption on two Lanthanide Based MOFs

    University essay from Stockholms universitet/Avdelningen för fysikalisk kemi

    Author : Alfredo Metere; [2009]
    Keywords : Lanthanide; MOF; Adsorption;

    Abstract : Metal-organic frameworks are porous materials resulting from the coordination of a metal ion (the Lewis acid) and organic polydentated ligands. In the case of the MOFs, the SBU (Secondary Building Unit) is defined by taking the active groups of the ligands involved in coordination and the metal ion as a block. READ MORE
