  1. 1. Process development for platform chemical production from agricultural and forestry residues

    Author : David Nickel; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; AGRICULTURAL SCIENCES; multi-scale variability analysis; logging residues; ethanol; lactic acid; preadaptation; pretreatment; lignocellulose; Biorefinery; platform chemicals; multi-feed SSCF; mixed feedstocks;

    Abstract : As part of a bio-based economy, biorefineries are envisaged to sustainably produce platform chemicals via biochemical conversion of agricultural and forestry residues. However, supply risks, the recalcitrance of lignocellulosic biomass, and inhibitor formation during pre­treatment impair the economic feasibility of such biorefineries. READ MORE

  2. 2. Generalised stacking fault energy and plastic deformation of austenitic stainless steels

    Author : David Molnar; Levente Vitos; Guocai Chai; Dávid Sándor Molnár; Högskolan Dalarna; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; stacking fault energy; stainless steel; plasticity; deformation; ab initio; Steel Forming and Surface Engineering; Stålformning och ytteknik; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : Austenitic stainless steels are primarily known for their exceptional corrosion resistance. They have the face centred cubic (FCC) structure which is stabilised by adding nickel to the Fe-Cr alloy. The Fe-Cr-Ni system can be further extended by adding other elements such as Mn, Mo, N, C, etc. in order to improve the properties. READ MORE

  3. 3. Stacking fault energy and deformation behaviour of austenitic stainless steels: a joint theoretical-experimental study

    Author : Dávid Sándor Molnár; Levente Vitos; Göran Engberg; Guocai Chai; David Molnar; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; austenitic stainless steel; deformation properties; stacking fault energy; electron backscatter diffraction; ab initio; Materials Science and Engineering; Teknisk materialvetenskap; Steel Forming and Surface Engineering; Stålformning och ytteknik;

    Abstract : Austenitiska rostfria stål är främst kända för sin exceptionella korrosionsbeständighet. De har en ytcentrerad kubisk (FCC) struktur som stabiliseras genom att nickel, mangan eller kväve tillsätts till Fe-Cr legeringen. Fe-Cr-Ni-systemet kan utökas ytterligare genom tillsats av andra element såsom Mo, Cu, Ti, C, etc. READ MORE

  4. 4. Electro-Acoustic and Electronic Applications Utilizing Thin Film Aluminium Nitride

    Author : David Michael Martin; J. Olsson; I. Katardjiev; S. Gevorgian; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AlN; FBAR; FPAR; CMP; SOI; Nickel Silicide; Wafer Bonding; Electronics; Elektronik; Elektronik; Electronics;

    Abstract : In recent years there has been a huge increase in the growth of communication systems such as mobile phones, wireless local area networks (WLAN), satellite navigation and various other forms of wireless data communication that have made analogue frequency control a key issue. The increase in frequency spectrum crowding and the increase of frequency into microwave region, along with the need for minimisation and capacity improvement, has shown the need for the development of high performance, miniature, on-chip filters operating in the low to medium GHz frequency range.
