1. 16. Preparation, characterization and testing of model catalysts for CO oxidation and CO2 hydrogenation

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

   Author : Stefano Albertin; [2017]
   Keywords : Surface science; Rhodium; Nanoparticles; Catalysis; CO2; Physics and Astronomy;

   Abstract : A joint research between Lund University and Chalmers Competence Centre for Catalysis have shown promising results for a Rh-based catalyst for CO2 hydrogenation catalytic applications. The original catalyst consisted of a dispersion of nanoparticles onto a porous 3D oxide network. READ MORE

3. 17. Electric Field Domains in Quantum Cascade Lasers

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

   Author : Tim Almqvist; [2017]
   Keywords : quantum cascade laser; QCL; electric field domain; EFD; NDR; negative differential resistivity; simulations; Tim; Almqvist; kvantkaskadlaser; Physics and Astronomy;

   Abstract : Quantum cascade lasers (QCLs) are periodic semiconductor heterostructures, capable of producing laser gain. They have become an important source of coherent radiation in the mid infrared, and THz frequency regions. QCLs are non-linear electric devices, and often have bias regions of negative differential resistivity (NDR). READ MORE

4. 18. Titanium vacancy diffusion in TiN via non-equilibrium ab initio molecular dynamics

   University essay from Linköpings universitet/Teoretisk Fysik

   Author : Davide Gambino; [2016]
   Keywords : Titanium nitride; Ti monovacancy migration; Non-equilibrium ab initio molecular dynamics; Color diffusion algorithm; Statistics for stochastic events;

   Abstract : Transition metal nitrides (TMNs) refractory ceramic materials are  widely employed as wear-resistant protective coatings in industrial machining as well as diffusion barriers inhibiting migration of metal impurities from the interconnects to the semiconducting region of electronic devices. TiN is the prototype of this class of materials and the most studied among TMNs. READ MORE

5. 19. Optical Tweezers and Maxwell's Demon

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

   Author : Markus Aspegren; [2016]
   Keywords : Physics and Astronomy;

   Abstract : Future nanoscale applications of Brownian motors will benefit from further development of stochastic thermodynamics, bridging the the properties of systems in non-equilibrium with those in equilibrium. This thesis presents the first step towards a device mimicking Maxwell's demon, which will be used for a study of systems out of equilibrium. READ MORE

6. 20. Multi-energy well kinetic modeling of novel PAH formation pathways in flames

   University essay from KTH/Kraft- och värmeteknologi

   Author : Nicola Giramondi; [2016]
   Keywords : Polycyclic Aromatic Hydrocarbons; soot; laminar flame; flame calculation; quantum chemical calculation; non-equilibrium kinetic modeling.;

   Abstract : Polycyclic Aromatic Hydrocarbons (PAHs) are harmful by-products formed during combustion of hydrocarbons under locally fuel-rich conditions followed by incomplete combustion. PAHs act as precursors during the formation of soot. PAHs and soot are harmful for human health and legislation limits the emission of unburned hydrocarbons and soot. READ MORE
