  5. 3. Ultrasonic testing of components produced with additive manufacturing : Towards improved detection and classification of defects

    Author : Mikael Sahl; Håkan Wirdelius; Erik Lindgren; Oskar Tofeldt; Madis Ratassepp; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Non-Destructive Testing NDT ; Super alloys; Microstructure; Ultrasonic Testing UT ; Productivity Enhancement; Production Technology; Produktionsteknik;

    Abstract : The focus in this work is on the use of ultrasonic testing as a method for inspecting components manufactured through additive manufacturing (AM) processes. The research is rooted in the need for effective non-destructive testingtechniques that can adapt to the unique challenges posed by AM-produced materials, including complex defect geometries and surface conditions.

  6. 4. Synthesis of Small Molecules Targeting ADP-Ribosyltransferases and Total Synthesis of Resveratrol Based Natural Products

    Author : Anders Lindgren; Mikael Elofsson; Nicholas Westwood; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organic synthesis; quinazolinone; ARTD; PARP; total synthesis; polyphenols; bensofuranes; organisk kemi; Organic Chemistry;

    Abstract : Diphtheria Toxin-like ADP-RibosyltransferasesThe Human ADP-ribosyl transferases (ARTDs) are a group of poorly studied enzymes which are believed to be involved in e.g. DNA repair, protein degradation, transcription regulation and cell death. Medicinal chemistry programmes aimed at developing selective inhibitors of these ARTDs were initiated. READ MORE

  7. 5. Nematic Liquid Crystal Spatial Light Modulators for Laser Beam Steering

    Author : Emil Hällstig; Mikael Lindgren; Lars Sjöqvist; William Crossland; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; spatial light modulator; liquid crystal; beam steering; tracking; phase modulation; fringing field; director distribution; finite-difference time-domain; polarization; temporal properties; Fysik; Physics; Fysik;

    Abstract : Laser beam control is important in many applications. Phase modulating spatial light modulators (SLMs) can be used to electronically alter the phase distribution of an optical wave-front and thus change the direction and shape of a laser beam. READ MORE
