1. 16. Platinum-free Electrocatalysts : Design, Synthesis, and Energy Applications

   Författare :Yi Yang; Inna Soroka; Carina Lagergren; Serhiy Cherevko; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pt-free electrocatalysts; γ-radiation induced synthesis; size; morphology; structure; and composition of nanocatalysts; ORR; catalytic activity and durability; formation mechanism of catalyst materials in aqueous solutions.; Kemi; Chemistry;

   Sammanfattning : Pt is one of the most commonly used catalysts for green energy applications, such as fuel cells, electrolyzers, and dye-sensitized solar cells. Although enormous effort has been put into improving the catalytic activity and minimizing the usage of Pt in the catalysts, the low abundance and high price of Pt still limit the large-scale commercialization of green energy devices and facilities.

3. 17. Molecular basis for galectin-ligand interactions : Design, synthesis and analysis of ligands

   Författare :Kristoffer Peterson; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Galectin; Structure-based design; Thiodigalactoside; Huisgen 1; 3-dipolar cycloaddition; Protein-ligand binding interactions;

   Sammanfattning : Galectins are a class of β-galactoside-binding proteins that bind glycoconjugates and have been implicated in cancer, regulation of immunity and inflammation. Design and synthesis have achieved highly potent and selective galectin ligands that can inhibit interactions with glycoproteins and have consequent cellular effects. LÄS MER

   Sammanfattning : The area of catalysis has had an immeasurable impact on modern society. This has been acknowledged through several Nobel prizes during the 20th century ranging from Haber (1918) for the synthesis of ammonia to Richard F. Heck, Ei-ichi Negishi, and Akira Suzuki (2010) for palladium-catalyzed cross-coupling reactions. LÄS MER

7. 20. Studies of second coordination sphere effects and metal variations on [FeFe]-hydrogenase mimics

   Författare :Holly J. Redman; Gustav Berggren; Pickett Chris; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hydrogenases; synthesis; inorganic chemistry; molecular biomimetics; spectroscopy; FTIR; cyclic voltammetry; catalysis; Chemistry with specialization in Molecular Biomimetics; Kemi med inriktning mot molekylär biomimetik;

   Sammanfattning : Mitigation of climate change motivates researchers to explore hydrogen as a potential energy carrier. Unfortunately, widespread use of hydrogen as an energy carrier is limited by numerous challenges in its production, including high energy consumption; high economic cost; current reliance on rare metals such as platinum.
