1. 6. Synthesis and characterization of novel thiophene based tetramers for potential detection of protein aggregates

   Master-uppsats, Linköpings universitet/Kemi

   Författare :Maria Alfredsson; [2019]
   Nyckelord :Organic chemistry; synthesis; oligothiophenes; Alzheimer’s Disease; Suzuki cross coupling; bromination;

   Sammanfattning : Alzheimer’s disease is a big problem in the elderly population. An important tool in gaining insight in this disease are staining studies using different probes. Conjugated oligothiophenes have shown promising properties as probes and in this thesis new potential probes have been made. LÄS MER

3. 7. 2-Hydroxypyridine-Ligated Pd-complexes as pre-catalysts in Hydrogen Borrowing Chemistry α -Alkylation of Ketones Using Alcohols

   Master-uppsats, Lunds universitet/Kemiska institutionen

   Författare :Ayesha Kanwal; [2017]
   Nyckelord :Hydrogen Borrowing in activation of alcohols; Palladium in Catalysis; hydrogenation and dehydrogenation reactions; hydrogen borrowing concept for hydrogenation and dehydrogenation reactions; 2-hydroxyquinoline Ligand; 2-hydroxy pyridine ligands; inorganic chemistry; oorganisk kemi; Chemistry;

   Sammanfattning : An efficient method for selective alpha-alkylation of ketones with alcohols was developed using 2-hydroxypyridine-based ligands coordinated by palladium as pre-catalysts. The reactions were performed without additional additives under mild reaction conditions. The method is environmentally friendly to build C-C bond as water is the only byproduct. LÄS MER

4. 8. Towards Nickel Boride Catalyzed C-C Coupling Reactions

   Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

   Författare :Ágnes Lakó; [2017]
   Nyckelord :heterogeneous catalysis; nickel catalysis; coupling reactions; cross-coupling; homocoupling;

   Sammanfattning : This thesis focuses on the study of nickel boride as a catalyst in various coupling reactions. The nickel boride catalyst was investigated in three different coupling reactions, the experiments aimed at understanding the activity and catalytic properties of nickel boride. LÄS MER

5. 9. X-Ray Photoelectron Spectroscopy of Metal & Metal-based Clusters: Au, Ag & Sn Cases.

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

   Författare :Charles Wright; [2016]
   Nyckelord :Physics; Photoelectron; Spectroscopy; Cluster; Clusters; Gold; Silver; Tin; Synchrotron; X-Ray; Physics and Astronomy;

   Sammanfattning : Clusters are particles which consist of a finite number (2 − 10 ^6−7 ) of atoms/molecules. For the work presented in this thesis free clusters have been produced in order to study their properties, free of interfering substrates, using photoelectron spectroscopy at the MAX-lab synchrotron facility in Lund, Sweden.

7. 10. Design & Size Reduction analysis of Microstrip Hairpin Bandpass Filters

   Master-uppsats, Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

   Författare :HAMID ALI HASSAN; [2015]
   Nyckelord :Microstrip Hairpin Bandpass Filters;

   Sammanfattning : This thesis presents Design, Measurement and analysis for size reduction of the Coupled line micro strip Hairpin band pass filters (MHBPF’s). Hairpin filters are an interesting topic for microwave designers. These planar circuits are widely used in wireless transceivers and other microwave projects due to an easy design process. LÄS MER
