  1. 1. Carbon-based magnetic nanomaterials

    University dissertation from Umeå University

    Author : Valeria Zagaynova; Umeå universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbon nanotube; fullerene; single molecular magnet; Mn12; graphite fluoride; nanoporous carbon; molecular magnetism; magnetic properties; SQUID magnetometry; x-ray diffraction; Raman spectroscopy; Materials Science; materialvetenskap;

    Abstract : Magnetism of carbon-based materials is a challenging area for both fundamental research and possible applications. We present studies of low-dimensional carbon-based magnetic systems (fullerene-diluted molecular magnets, carbon nanotubes, graphite fluoride, and nanoporous carbon) by means of SQUID magnetometer, X-ray diffraction and vibrational spectroscopy, the latter techniques used as complementary instruments to find a correlation between the magnetic behaviour and the structure of the samples.

  2. 2. 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.

  3. 3. Functionalization and Characteization of Carbon-based Nanomaterials

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Nan Wang; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon nanomaterials; graphene; hybrid nanowires; flexible electronics; functionalization;

    Abstract : Surface functionalization of nanomaterials opens up unlimited possibilities to combine the distinct properties of inorganic, organic, or even bioactive components in a single material and bring novel functionalities in a wide range of applications ranging from electronics to catalysts and medicine carriers. So far, a variety of organic and inorganic nanomaterials have been explored to construct different functionalized nanomaterials. READ MORE

  4. 4. Synthesis and Characterization of Carbon Based One-Dimensional Structures Tuning Physical and Chemical Properties

    University dissertation from Umeå : Umeå University

    Author : HamidReza Barzegar; Umeå universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbon Nanotube; single-walled carbon nanotube; nitrogen doped; chemical vapor deposition; fullerene; hybrid structures; nanomaterials; nanomaterial;

    Abstract : Carbon nanostructures have been extensively used in different applications; ranging from electronic and optoelectronic devices to energy conversion. The interest stems from the fact that covalently bonded carbon atoms can form a wide variety of structures with zero-, one- and two-dimensional configuration with different physical properties.

  5. 5. Studies of carbon nanomaterials based on fullerenes and carbon nanotubes

    University dissertation from Umeå : Fysik

    Author : Agnieszka Iwasiewicz-Wabnig; Umeå universitet.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fullerenes; carbon nanotubes; fullerene polymers; intercalation compounds; high pressure; Raman spectroscopy; X-ray diffraction; atomic force microscopy; phase transitions; TECHNOLOGY Engineering physics Material physics with surface physics; TEKNIKVETENSKAP Teknisk fysik Materialfysik med ytfysik;

    Abstract : Materials based on fullerenes and carbon nanotubes are very much different from most “traditional” materials, primarily because they are built from nanosized molecules with highly symmetry-dependent properties. Being the subject of a very active research field over the last twenty years, carbon nanostructures proved to be indeed extraordinary. READ MORE
