  2. 11. Protocols with Heterogeneous Real-Time Services for High-Performance Embedded Networks

    Author : Carl Bergenhem; Högskolan i Halmstad; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Optical; Ring; Pipeline; Distributed; Parallel-Processing; Real-time; SAN; System Area Network; Heterogeneous; Service;

    Abstract : Network protocols for applications that demand high performance and heterogeneous real-time services are presented. These protocols control the medium access to the network and offer additional features to the user, both different user services for traffic and services for parallel and distributed real-time processing.

  4. 12. Development and Applications of Surface-Confined Transition Metal Complexes : Heterogeneous Catalysis and Anisotropic Particle Surfaces

    Author : Kristofer Eriksson; Jan-Erling Bäckvall; Graham Hutchings; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; heterogeneous catalysis; anisotropic particles; protein gradients; nanoparticles; organisk kemi; Organic Chemistry;

    Abstract : The main focus of this thesis has been directed towards developing novel surface-confined transition metal complexes for applications in heterogeneous catalysis and for the preparation of anisotropic particle surfaces. The first part describes the heterogenization of a homogeneous transition metal-based catalyst tetraphenyl cobalt porphyrin (CoTPP) on silicon wafers and on silica particles. READ MORE

    Abstract : Catalytic systems are one of the most effective technologies of modern chemical processes. The system uses a molecule called ‘catalyst’ that is capable of catalyzing a reaction without being produced or consumed during the process. READ MORE

  6. 14. Multiscale interfacial engineering of heterogeneous electrocatalysts : From structural design to mechanistic study

    Author : Shiqi Zhou; Jiayin Yuan; Martin Oschatz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; heterogeneous electrocatalysis; electronic structure; coordination environment; single-atom catalysts; strain effect; hydrogen evolution reaction kinetics; charge transfer; electrochemical CO^2 reduction; local enrichment; materialkemi; Materials Chemistry;

    Abstract : In a typical heterogeneous electrocatalytic reaction, for the given active sites, the electronic structure plays a determining role in electron transfer between the active sites and reactant molecules, which impacts the reaction efficiency. Besides the electronic properties of the electrocatalysts, the reaction interface at which the charge transfer occurs plays an important role in the reaction kinetics. READ MORE
