  2. 6. Nanoplasmonic Spectroscopy of Single Nanoparticles Tracking Size and Shape Effects in Pd Hydride Formation

    Author : Svetlana Syrenova; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hole-mask colloidal lithography; enthalpy of formation; palladium nanoparticles and nanocrystals; metal-hydrogen interactions; shrinking-hole colloidal lithography; localized surface plasmon resonance; dark field scattering spectroscopy; single particle spectroscopy; nanoscale effects; plasmonic sensors;

    Abstract : Localized surface plasmon resonance (LSPR) is a phenomenon of collective oscillation of conduction electrons in metal nanoparticles smaller than the wavelength of light that is used for its excitation. Plasmonic metal nanoparticles are able to confine light to extremely small volumes around them, i.e. below the diffraction limit. READ MORE

  4. 7. Computational Studies and Design of Biomolecular Diels-Alder Catalysis

    Author : Mats Linder; Tore Brinck; Kendall N. Houk; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computational chemistry; density functional theory; enzyme design; molecular modeling; organocatalysis; stepwise Diels-Alder; oxyanion hole;

    Abstract : The Diels-Alder reaction is one of the most powerful synthetic tools in organic chemistry, and asymmetric Diels-Alder catalysis allows for rapid construction of chiral carbon scaffolds. For this reason, considerable effort has been invested in developing efficient and stereoselective organo- and biocatalysts. READ MORE

  5. 8. Applications of Si1-xGex alloys for Ge devices and monolithic 3D integration

    Author : Konstantinos Garidis; Per-Erik Hellström; Mikael Östling; Sten Vollebregt; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon; germanium; epitaxy; selective; pn junction; germanium on insulator; GOI; Ge PFET; bonding; monolithic; sequential; three dimensional; 3D; low temperature; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : As the semiconductor industry moves beyond the 10 nm node, power consumption constraints and reduction of the negative impact of parasitic elements become important. Silicon germanium (Si1−xGex) alloys have been used to amplify the performance of Si based devices and integrated circuits (ICs) for decades. READ MORE

  6. 9. Experimental Aerothermal Study on Internal Jet Engine Structures

    Author : Isak Jonsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intermediate Compressor Duct; Aerothermal; multi-hole probe; Turbine Rear Structure; transition; experimental; IR-thermography;

    Abstract : For commercial aviation, one potential gain in efficiency can be found in the jet engine auxiliary modules, such as internal jet engine components. These components have historically largely been overlooked, prioritising units such as turbines or compressors. READ MORE
