1. 6. Studies towards ß-turn mimetics, synthesis of kedarosamine from threonine, and synthesis of glycopeptides from mucins and gp120

   Författare :Tatjana Vuljanic; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tn antigen; glycopeptides; glycosylation; diastereselective reduction; kedarosamine; kedarcidin chromophore; amino acids; peptide T; ß-turn mimetic; Organisk kemi; gp120; Organic chemistry;

   Sammanfattning : The secondary structure of proteins is crucial for proper function of the protein in biological systems. Peptide T, an octapeptide from the envelope glycoprotein gp120 of the HIV virus, has previously been shown to be responsible for binding to the CD4 receptor on T helper/inducer lymphocytes. LÄS MER

4. 8. Structure-Property Relationships in Chromophore-Organogel Assemblies: Consequences for Triplet-Triplet Annihilation and Singlet Fission

   Författare :Deise Fernanda Barbosa de Mattos; Chalmers tekniska högskola; []

   Sammanfattning : Better utilization of the solar spectrum by absorbing photons that are currently wasted by solar cells, due to the bandgap mismatch with the semiconductor, will help to improve the device efficiency. Two low energy photons can be upconverted to one high energy photon through triplet-triplet annihilation (TTA-UC); one high energy photon can be down converted to form two charge carriers through singlet fission (SF).
