  2. 16. Utilizing lignocellulose-based building blocks to develop recyclable polyesters

    Author : Nitin Valsange; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biobased; Polyester; Recycling;

    Abstract : With the growing global population and the demand for new applications, the production of fossil-based plastics is continuously increasing. This has led to serious environmental concerns about the depletion of fossil resources, land and marine pollution, and generation of greenhouse gas emissions. READ MORE

  4. 17. Influence of Electron Charge States in Nanoelectronic Building Blocks

    Author : Johan Piscator; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; silicon nanowire; conductance method; MOS; Schottky barrier lowering; CV; silicon on insulator SOI ; high-k; interface states; Schottky contacts; TSC.;

    Abstract : The continued efforts to improve performance and decrease size of semiconductor logic devices are facing serious challenges. In order to further develop one of the most important nanoelectronic building blocks, the metal-oxide-semiconductor field-effect-transistor (MOSFET), several major problems have to be solved.

  5. 18. Building Blocks for Low-Voltage Analog-to-Digital Interfaces

    Author : Prakash Harikumar; Jacob Wikner; Mikael Gustavsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In today’s system-on-chip (SoC) implementations, power consumption is a key performance specification. The proliferation of mobile communication devices and distributed wireless sensor networks has necessitated the development of power-efficient analog, radio-frequency (RF), and digital integrated circuits.

  6. 19. C1 Building Blocks: New Approaches for Thiomethylations and Esterification

    Author : Marcus Söderström; Luke R. Odell; Anders Karlén; Vittorio Pace; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Borontrifluoride; Dimethylsulfide; Thiomethylation; Methylthioethers; Dithioacetalation; Methyl-Dithioacetals; Friedel-Crafts; Diarylmethanes; Defluorination; Methyl-Dithioesters; Thioamides; Diazomethane; Esterification; Medicinal Chemistry; Läkemedelskemi; Medicinal Chemistry; Läkemedelskemi;

    Abstract : The thioether motif is found in numerous pharmaceuticals. The simplest form of this motif, the methyl-thioether is similarly found in many biologically active compounds and has exhibited many advantageous properties. The installation of the thiomethyl moiety can be troublesome due to the toxicity and malodor of small sulfur reagents. READ MORE

  7. 20. Towards Runtime-Assisted Cache Management for Task-Parallel Programs

    Author : Madhavan Manivannan; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; task parallelism; cache hierarchy; runtime system; dead blocks; multi-core architecture; sharing patterns;

    Abstract : Architects have adopted the shared memory model that implicitly manages cache coherence and cache capacity in hardware, mainly to aid programmability of multi-core architectures. The hardware mechanisms are however prone to inefficiencies because they are not tailored to the behavior of individual parallel applications. READ MORE
