  2. 1. Aspects on wettability and surface composition of modified wood

    Author : Lars-Elof Bryne; Ove Söderström; Charles R. Frihart; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wettability; contact angle; work of adhesion; Lewis acid-base; modified wood; Building engineering; Byggnadsteknik;

    Abstract : Wood is often combined with other materials such as thermoplastics, adhesives and coatings. In general, combinations of wood and polymers especially in outdoor exposure have poor long-term durability. READ MORE

  4. 2. Surface characterization of 2D transition metal carbides (MXenes)

    Author : Ingemar Persson; Per Persson; Justinas Palisaitis; Johanna Rosén; Vanya Darakchieva; Vincent Mauchamp; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Research on two-dimensional (2D) materials is a rapidly growing field owing to the wide range of new interesting properties found in 2D structures that are vastly different from their three-dimensional (3D) analogues. In addition, 2D materials embodies a significant surface area that facilitates a high degree of surface reactions per unit volume or mass, that is imperative in many applications such as catalysis, energy storage, energy conversion, filtration, and single molecule sensing.

  5. 3. Norovirus, causative agent of winter vomiting disease, exploits several histo-blood group glycans for adhesion

    Author : Gustaf E Rydell; Göteborgs universitet; []
    Keywords : norovirus; glycobiology; virus-like particle; FUT2; ABO H histo-blood group antigen; sialyl Lewis x; neoglycoprotein; glycosphingolipid; QCM-D; supported lipid bilayer;

    Abstract : Norovirus is recognized as the major cause of outbreaks of gastroenteritis world-wide, yet no vaccines or drugs are available for prevention or treatment of the virus infection. Challenge studies and binding studies using virus-like particles (VLPs) have suggested susceptibility to norovirus infection to be associated with secretor status. READ MORE

  6. 4. Lewis acid promoted endocyclic cleavage of glycosides and related acetals

    Author : Roger Olsson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; halichomycin; allylation; carbene; hydrogen bond; organozinc; organotitanium; furanosides; organoaluminium; pyranosides; glycosides; stereoselective; endocyclic cleavage; nucleophilic ring opening; ab initio; Organic chemistry; Organisk kemi;

    Abstract : This thesis is a summary of five papers concerning endocyclic cleavage of glycosides and related acetals. Simple lactol ethers undergo endocyclic cleavage to give acyclic chain extended products on treatment with organoaluminium and organotitanium reagents. READ MORE

  7. 5. Bispyridylamides as ligands in asymmetric catalysis

    Author : Oscar Belda de Lama; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; asymmetric catalysis; chiral ligand; pyridine; amide; allylic alkylation; enantioselective; cyanation; ring-opening; chiral Lewis acid;

    Abstract : This thesis deals with the preparation and use of chiralbispyridylamides as ligands in metal-catalyzed asymmetricreactions. The compounds were prepared by amide formation usingdifferent coupling reagents. READ MORE
