2. 11. Carbohydrate-Based Inhibitors of Pathogen Adhesion to Cell Surface Glycoconjugates

   Author : Henrik C Hansen; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Galabiose analogs; Globotriose analogs; Escherichia coli; verotoxin; PapG adhesion; Streptococcus suis; Dendrimers; Multivalency; Amino-deoxy analogs; Organic chemistry; Inhibitor; Ceramide analogs; Glycoconjugates; Organisk kemi;

   Abstract : The fact that a growing number of pathogens develop resistance against traditional treatment is a growing medical problem. Infections, which until now have been harmless, might turn into life threatening diseases. These problems have led to an intensified search for alternative treatments. Analogs of cell surface glycoconjugates are an alternative. READ MORE

4. 12. Environmental Assessment of Alternative Durable Water Repellent Chemicals. First steps towards a holistic assessment

   Author : Hanna Holmquist; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LCA; diffuse emissions; wax; silicones; risk assessment; DWR; PFAS; CAA; dendrimers;

   Abstract : Durable water repellent (DWR) finishes are applied to textiles to impart water and in some cases oil repellency. Water (and oil) repellency can be an important contribution to a textile’s performance, for comfort or for the protection of human lives under extreme conditions. READ MORE

6. 14. Tuning Properties of Surfaces and Nanoscopic Objects using Dendronization and Controlled Polymerizations

   Author : Emma Östmark; Eva Malmström; Heikki Tenhu; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dendrimers; dendronized polymers; cellulose; Atom Transfer Radical Polymerization; Ring-Opening Polymerization; surface modification; grafting; superhydrophobic; amphiphilic polymer; block copolymer; Atomic Force Microscopy; Polymer chemistry; Polymerkemi;

   Abstract : In this study, dendronization and grafting via controlled polymerization techniques, atom transfer radical polymerization (ATRP) and ring-opening polymerization (ROP), have been explored. Modification of surfaces and cellulose using these techniques, which enable grafting of well-defined polymer architectures, has been investigated. READ MORE

7. 15. Synthesis of aromatic bis- and tris(amino acids) and chiral dendrimers

   Author : Andreas Ritzén; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Organic chemistry; HWE reaction; asymmetric hydrogenation; Heck reaction; Amino acids; chiral dendrimers;

   Abstract : A number of protected aromatic bis- and tris(amino acids) have been synthesised by catalytic asymmetric hydrogenation of the corresponding didehydroamino acid derivatives. The didehydroamino acid derivatives were prepared either by a Heck coupling of a 2-amidoacrylate with an aryl dihalide, or by Horner-Wadsworth-Emmons olefination of aromatic aldehydes with phosphonylglycine reagents.
