  2. 16. Electrocatalysts for sustainable hydrogen energy : disordered and heterogeneous nanomaterials

    Author : Joakim Ekspong; Thomas Wågberg; Ludvig Edman; Tomas Edvinsson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Water splitting; Electrochemistry; Nanomaterials; Density functional theory; Hydrogen evolution; MoS2; Fuel cell; nanomaterials; nanomaterial; fysik; Physics; Physical Chemistry; fysikalisk kemi;

    Abstract : With the current global greenhouse gas emissions, our remaining carbon budget is depleted in only 7 years. After that, several biophysical systems are predicted to collapse such as the arctic ice, coral reefs and the permafrost, leading to potentially irreversible consequences. READ MORE

  4. 17. Software Concerns for Execution on Heterogeneous Platforms

    Author : Hugo Sica de Andrade; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Software Architecture; Heterogeneous Platforms; Software Deployment; Interprocess Communication;

    Abstract : Context: Heterogeneous computing, i.e., computing performed on different types of execution units, such as CPUs, GPUs, FPGAs, has shown to be a feasible path towards higher performance and less energy consumption. Heterogeneous platforms are specialized on specific types of computation, e. READ MORE

  5. 18. Metal-Organic Frameworks (MOFs) for Heterogeneous Catalysis : Synthesis and Characterization

    Author : Mikaela Gustafsson; Xiaodong Zou; Pascal Van Der Voort; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metal-organic frameworks; zeolitic imidazolate frameworks; functionalized linkers; structural transformation; heterogeneous catalysis; Structural Chemistry; strukturkemi;

    Abstract : Metal-organic frameworks (MOFs) are crystalline hybrid materials with interesting chemical and physical properties. This thesis is focused on the synthesis and characterization of different MOFs and their use in heterogeneous catalysis. READ MORE

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microelectromechanical systems; MEMS; silicon; wafer-level; integration; heterogeneous integration; transfer integration; packaging; assembly; wafer bonding; adhesive bonding; eutectic bonding; release etching; electrochemical etching; microvalves; microactuator; Shape Memory Alloy; SMA; NITINOL; TiNi; NiTi; cold-state reset; bias spring; stress layers; crossbar switch; routing; switch; switch array; electrostatic actuator; S-shaped actuator; zipper actuator; addressing; transfer stamping; blue tape; Computer engineering; Datorteknik;

    Abstract : This thesis presents methods for the wafer-level integration of shape memory alloy (SMA) and electrostatic actuators to functionalize MEMS devices. The integration methods are based on heterogeneous integration, which is the integration of different materials and technologies. READ MORE

  7. 20. Efficient Execution Paradigms for Parallel Heterogeneous Architectures

    Author : Konstantinos Koukos; Stefanos Kaxiras; Margaret Martonosi; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Decoupled Execution; Performance; Energy; DVFS; Compiler Optimizations; Heterogeneous Coherence; Computer Science; Datavetenskap;

    Abstract : This thesis proposes novel, efficient execution-paradigms for parallel heterogeneous architectures. The end of Dennard scaling is threatening the effectiveness of DVFS in future nodes; therefore, new execution paradigms are required to exploit the non-linear relationship between performance and energy efficiency of memory-bound application-regions.
