  2. 6. The chemical nature of CO2 adsorption in zeolite A

    Author : Przemyslaw Rzepka; Niklas Hedin; Webley Paul; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CO2 adsorption; flue gas CO2 capture; biogas upgrading; zeolite |NaK|-A; physisorption; chemisorption; kinetic separation; in situ diffraction; synchrotron XRD; NPD; NMR; IR; Materials Chemistry; materialkemi;

    Abstract : The climate changes are accelerated by increasing levels of carbon dioxide in the atmosphere connected to the fossil-fuel-based energy system. Substantial reforms of the system are needed immediately and could include the implementation of carbon capture and storage (CCS) technologies. READ MORE

  4. 7. Molecular Alligator Clips: A Study of Metal-Molecule Contacts for Molecular Electronics

    Author : Anton Grigoriev; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nonequilibrium Green s functions; single crystal surfaces; nanostructures; chemisorption; selenium; low index single crystal surface; density functional calculations; organic molecules; sulphur; nonequilibrium electron transport; gold;

    Abstract : In this thesis we present a computational study of the elementary building blocks for molecular electronics, interconnected electronic devices with critical dimensions below 5 nm. Building electronic circuits on that scale requires stable connection between the various parts of the device and to the macroscopic metal electrodes, needed for power supply, support and integration with conventional electronics.

  5. 8. Carbohydrate-specific, boronate-containing copolymers: from sugar-sensing to cell adhesion

    Author : Marina Kuzimenkova; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface grafting; chemisorption; boronic acid; carbohydrates; affinity; chromatography; smart polymers; biomimetics; hydrogels; molecular recognition; diffusion; sugar-sensing; cell adhesion;

    Abstract : Carbohydrates play a major role in many cell recognition events and metabolic pathways of living organisms. Synthetic carbohydrate receptors are of great interest for the chemical design of sugar sensors, materials for cell separation, cell immobilization, drug delivery and other biomedical/biotechnological applications.
