2. 1. The Electrochemistry of LiNi0.5-xMn1.5+xO4-δ in Li-ion Batteries : Structure, Side-reactions and Cross-talk

   Author : Burak Aktekin; Kristina Edström; Daniel Brandell; Wolfgang Zipprich; Fernanda Lodi Marzano; Christian Masquelier; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; LNMO; High-voltage spinel; FEC; Cross-talk; Cation ordering; Oxygen deficiency; Anionic redox; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

   Abstract : The use of Li-ion batteries in portable electronic products is today widespread and on-going research is extensively dedicated to improve their performance and energy density for use in electric vehicles. The largest contribution to the overall cell weight comes from the positive electrode material, and improvements regarding this component thereby render a high potential for the development of these types of batteries.

4. 2. Palladium(0)-Catalysed Carbonylative Multicomponent Reactions : Synthesis of Heterocycles and the Application of Quinolinyl Pyrimidines as Enzyme Inhibitors

   Author : Linda Åkerbladh; Mats Larhed; Luke Odell; Anders Karlén; Lise-Lotte Gundersen; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Palladium catalysis; Carbonylation; Multicomponent reactions; Domino reactions; Heterocycles; 4-Quinolones; 2-Aminoquinazolinones; Benzoxazinones; N-Acylguanidines; Type II NADH dehydrogenase; NDH-2;

   Abstract : Palladium-catalysed carbonylative multicomponent reactions have proven useful for the synthesis of structurally diverse compounds. Carbon monoxide serves as an atom-efficient, one-carbon building block, which allows for further structural elaboration of the carbonyl compound. READ MORE

5. 3. Theoretical studies of chemical dynamics on excited states, driven by non-adiabatic effects : Charge recombination reactions

   Author : Sifiso Musa Nkambule; Åsa Larson; Adam Kirrander; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mutual neutralization; Dissociative recombination; electronic structure; non-adiabatic; teoretisk fysik; Theoretical Physics;

   Abstract : This thesis is based on theoretical studies of molecular collisions occurring at relatively low to intermediate collision energies. The collisions are called dissociative recombination (DR) and mutual neutralization (MN). READ MORE

6. 4. Photocontact Allergy to Ketoprofen and Simultaneous Contact Allergies

   Author : Victoria Marmgren; Yrkes- och miljödermatologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ketoprofen; photoallergic contact dermatitis; cross-reactions; photoallergic; photopatch testing; Fragrance; patch testing; simultaneous reactions; occlusion;

   Abstract : Ketoprofen is a non-steroidal anti-inflammatory drug with analgesic, antipyretic, and anti-inflammatory properties. It is available in both oral and topical formulations. Photocontact allergy to topically applied ketoprofen has been the most frequent side effect of the formulation, and is fairly well studied. READ MORE

7. 5. New Methods for the Synthesis of Vicinal Stereocenters : Palladium-Catalyzed Domino Reactions and Asymmetric Transfer Hydrogenation

   Author : Brinton Seashore-Ludlow; Somfai Peter; Kevin Booker-Milburn; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; asymmetric synthesis; domino reactions; palladium-catalyzed reactions; oxindoles; amino alcohols;

   Abstract : In this thesis the synthesis of vicinal stereocenters is investigated in two distinct contexts, namely the construction of 3,3-disubstituted oxindoles and the synthesis of b-hydroxy-a-amino acids. Both scaffolds are prevalent in a range of natural products and biologically relevant compounds and, therefore, methods for their synthesis are of great import. READ MORE
