    Abstract : Today, the demand for speed in drug discovery is constantly increasing, particularly in the iterative processes of hit validation and expansion and lead optimization. Irradiation with microwaves (MWs) has been applied in the area of organic synthesis to accelerate chemical reactions and to facilitate the generation of new chemical entities since 1986. READ MORE

  2. 2. Asymmetric catalysis ligand design and microwave acceleration

    University dissertation from Stockholm : Kemi

    Author : Ulf Bremberg; KTH.; [2000]
    Keywords : ;

    Abstract : This thesis deals partly with the design and synthesis ofligands for use in asymmetric catalysis, and partly with theapplication of microwave heating on metal-based asymmetriccatalytic reactions.Enantiomerically pure pyridyl alcohols and bipyridylalcohols were synthesized from the chiral pool for future usein asymmetric catalysis.

  3. 3. Carbohydrate-Functionalized Nanomaterials Synthesis, Characterization and Biorecognition Studies

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Na Kong; KTH.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbohydrate; glyconanomaterials; perfluorophenyl azide PFPA ; CuAAC; AAAC; coupling chemistry; 19 F q NMR; lectin; carbon nanomaterials; microwave irradiation; Kemi; Chemistry; Biotechnology; Bioteknologi;

    Abstract : This thesis focuses on the development of carbohydrate coupling chemistry on nanomaterials and their biological activity studies. It is divided into two parts:In part one, two carbohydrate immobilization approaches, based on perfluorophenyl azide (PFPA)-functionalized silica nanoparticles (SNPs), are presented, where the binding affinity of the glyconanoparticles was evaluated through carbohydrate-lectin interaction.

  4. 4. Isolation, characterization and enzymatic hydrolysis of water-soluble wood polysaccharides

    University dissertation from Henrik Stålbrand, dep. Biochemistry Lund University

    Author : Jon Lundqvist; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; size exclusion chromatography; beta-mannosidase; beta-mannanase; endoglucanase; ethyl hydoxyethyl cellulose; metabolism; Biokemi; Biochemistry; Metabolism; microwave irradiation; O-acetyl-galactoglucomannan; isolation;

    Abstract : The need for new renewable products has enhanced the interest in cellulose and hemicellulose as raw material. The wood plant cell wall is a complex mixture of cellulose, hemicellulose, lignin and minor amounts of pectin, proteins and extractives. Several interactions between the compounds make them difficult to separate without modification. READ MORE

  5. 5. Green Chemical Synthesis of II-VI Semiconductor Quantum Dots

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Robina Shahid; KTH.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Semiconductor; Quantum Dots; Microwave; Ionic Liquids; Green Chemical Syntheis; Quantum Confinement; Optical Properties;

    Abstract : Nanotechnology is the science and technology of manipulating materials at atomic and molecular scale with properties different from bulk. Semiconductor QDs are important class of nanomaterials with unique physical and chemical properties owing to the quantum confinement effect. READ MORE
