1. 1. Iron nutrition dynamics - Differences between calcicole and calcifuge plants

   Författare :Angelika Zohlen; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 10-phenanthroline; 1; chlorophyll; plaque; root; leaf; immobilization; plants; calcifuge; Iron; calcicole; Plant ecology; Växtekologi;

   Sammanfattning : One third of the earth´s soils is calcareous. Calcifuge plants are excluded from these soils, and one of the main causes is Fe deficiency, as Fe solubility in calcareous soil is very low. A lack of Fe lowers chlorophyll content, visible as yellowing of leaves, called chlorosis. LÄS MER

3. 2. Controlling function by structure-intermolecular interactions and crystal engineering with N-donor ligands

   Författare :Mohamed I D M Ghazzali; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; OPL; 10 phenanthroline]2 .; single crystal diffraction; intermolecular interactions; crystal engineering; Fe II coordination polymers; Schiff’s bases; porphyrins; intercalation; [ Ru tris-1;

   Sammanfattning : In the solid state regime, crystal engineering based on non-covalent synthesis requires an intuition about the intermolecular forces that can dictate the molecular architecture. Hydrogen bonds have become an instrumental tool in the self assembly and supramolecular chemistry. LÄS MER

4. 3. Combined experimental and theoretical studies of dithiocarbamate complexes of yttrium, lanthanum and bismuth

   Författare :Vasantha Gowda; John V. Hanna; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

   Sammanfattning : Metal-dithiocarbamate complexes find wide-ranging applications in nanomaterial and metalseparation science, and have potential use as chemotherapeutic, pesticides, and as additives tolubricants. A highly versatile dialkyldithiocarbamate (R2NCS2–) ligand can form stablecomplexes with all the transition elements and also the majority of main group, lanthanide andactinide elements. LÄS MER

5. 4. On Thallium (III) and binuclear platinum-thallium complexes with N-donor ligands in solution and in solid

   Författare :Guibin Ma; KTH; []
   Nyckelord :thallium; platinum; cyanide; n-donor ligand; metal-metal bond multinuclear NMR; raman spectroscopy;

   Sammanfattning : This thesis describes the synthesis, structure, equilibriaand other properties of novel thallium(III) monomeric andplatinum-bonded complexes with nitrogen donor ligandsethylenediamine, diethylenetriamine, triethylenetetramine,porphyrin, 2,2'-bipyridine and 1,10-phenanthroline in solutionand in solid.The existence of three complexes withthe general formula[Tl(en)n]3+(n = 1-3) and their overall stability constantshave been established in pyridine.

7. 5. Novel Metal-Mediated Organic Transformations : Focusing on Microwave Acceleration and the Oxidative Heck Reaction

   Författare :Per-Anders Enquist; Mats Larhed; Anders Hallberg; Troels Skrydstrup; Uppsala universitet; []
   Nyckelord :Organic chemistry; palladium II ; oxidative Heck reaction; high-throughput-chemistry; microwave acceleration; dicobalt octacarbonyl; in situ carbonylation; urea; diaryl ketones; ESI-MS; Organisk kemi;

   Sammanfattning : Transition metals have played an important role in synthetic organic chemistry for more than a century, and offer catalytic transformations that would have been impossible with classical chemistry. One of the most useful and versatile of the transition metals is palladium, which over the years has catalyzed many important carbon-carbon forming reactions. LÄS MER
