  1. 1. Mesoporous Building Blocks : Synthesis and Characterization of Mesoporous Silica Particles and Films

    Author : Emma M. Björk; Magnus Odén; Fredik Söderlind; José Córdoba; Mika Lindén; Linköpings universitet; []
    Keywords : ;

    Abstract : Catalyst supports, drug delivery systems, hosts for nanoparticles, and solar cells are just some examples of the wide range of exciting applications for mesoporous silica. In order to optimize the performance of a specific application, controlling the material’s morphology and pore size is crucial. READ MORE

  2. 2. CMOS Transceiver Front-Ends in Mobile Communication Handsets : Architectures and Building Blocks

    Author : Ellie Cijvat; Henrik Sjöland; Pietro Andreani; Pieternella Cijvat; Lund University; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; RF CMOS; Wireless Communication; Receiver; Transmitter; Power Amplifier; Harmonic Distortion; Electrical engineering; Elektroteknik; Telecommunication engineering; Telekommunikationsteknik; Electrotechnology; Elektroteknik alt Electrical engineering; RF CMOS;

    Abstract : For mobile communication systems in the low-GHz range, CMOS has increasingly become the technology of choice, and the level of integration in mobile handsets has risen. The use of off-chip components, which increases the handset assembly time and costs, is preferably avoided. READ MORE

  4. 4. Natural products from nonracemie building blocks : synthesis of pine sawfly pheromones

    Author : Michael Larsson; Torbjörn Norin; Gunnar Westman; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Total synthesis; diastereoselective addition; dimethylzinc; Lewis acid; alkyllithium; Organisk kemi; Organic chemistry; Organisk kemi;

    Abstract : This thesis describes a number of synthetic approaches for obtaining chiral, enantiomerically pure natural products, in particular some semiochemicals. This has been accomplished by using various strategies; by starting from compounds from the chiral pool, by using chiral auxiliaries, via enzymatic resolutions or by chemical asymmetric synthesis.

  5. 5. The building blocks of sound symbolism

    Author : Niklas Erben Johansson; Allmän språkvetenskap; []
    Keywords : HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; sound symbolism; Iconicity; typology; language evolution; lexicon;

    Abstract : Languages contain thousands of words each and are made up by a seemingly endless collection of sound combinations. Yet a subsection of these show clear signs of corresponding word shapes for the same meanings which is generally known as vocal iconicity and sound symbolism. READ MORE
