    Författare :Maria Lundin; Eva Blomberg; Thomas Arnebrant; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Layer-by-layer; multilayer; adsorption; biopolymers; Chitosan; Heparin; Mucin; Albumin; Lysozyme; β-casein; SDS; QCM-D; Ellipsometri; DPI; TIRF; FRET; SFA; layer structure; solvent content; vertical diffusion; exponential growth; solid-liquid interface; deposition conditions; Surface and colloid chemistry; Yt- och kolloidkemi;

    Sammanfattning : It is widely known that surfaces play an important role in numerous biological processes and technological applications. Thus, being able to modify surface properties provides an opportunity to control many phenomena occurring at interfaces. LÄS MER

  3. 2. LiFeSO4F as a Cathode Material for Lithium-Ion Batteries : Synthesis, Structure, and Function

    Författare :Adam Sobkowiak; Fredrik Björefors; Kristina Edström; Anna Andersson; M. Rosa Palacin; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Li-ion battery; cathode; LiFeSO4F; tavorite; triplite; synthesis; performance; structure; coating; PEDOT; XRD; Mössbauer spectrocopy; SEM; TEM; electrochemistry; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : In this thesis, two recently discovered polymorphs of LiFeSO4F, adopting a tavorite- and triplite-type structure, were investigated as potential candidates for use as cathode materials in Li-ion batteries. The studies aimed at enriching the fundamental understanding of the synthetic preparations, structural properties, and electrochemical functionality of these materials. LÄS MER

  4. 3. Layered Design: Concepts, Case Studies and Processes - Theories and Implementations

    Författare :Linn Gustafsson Christiernin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Structure; and Process; Adaptability; Layer; Complex Interfaces; Experience; Sequence; Divided functions; Design;

    Sammanfattning : Many modern applications are focused on providing as many functions as possible and attract as many users groups as possible. The interfaces become very advanced but also quite complex. In many cases the design is perceived rather difficult by the end users. LÄS MER

  7. 5. Formation stability and electronic structure of surfaces and interfaces from first principles

    Författare :Jochen Rohrer; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; band structure; van der Waals interaction; electronic structure; graphane; graphene; atomic structure; growth; thin film; interface; density functional theory; CVD; Alumina; nucleation;

    Sammanfattning : This thesis deals with two closely interwoven aspects of first-principle(density functional theory) materials modeling:(1)~prediction of atomic structure & chemical composition,and (2)~prediction of electronic properties.In the first part, we focus on atomic structure (AS) and chemical composition (CC) of surface and interface systems.
