  1. 1. Microfabrication of Optical Components in Synthetic Diamond Infrared Optics for Applications  in Astronomy and Spectroscopy

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ernesto Vargas Catalan; Uppsala universitet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diamond; microfabrication; microoptics; astronomy; IR-spectroscopy; corongraph; waveguide;

    Abstract : Infrared optics is a broad general term, relevant to a range of fields. The manufactured diamond optical components utilized within this thesis were applied to both astronomy, in which direct imaging of star system using large ground-based telescopes and diamond coronagraphs was performed, and in absorption spectroscopy probing solvents and proteins using a tuneable quantum cascade laser and diamond waveguides.

  5. 5. Microscale Tools for Sample Preparation, Separation and Detection of Neuropeptides

    University dissertation from Uppsala : Kemiska institutionen

    Author : Andreas Dahlin; Uppsala universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Neuropeptides; Microchip; Enhanced microdialysis; Poly dimethylsiloxane PDMS ; Electrospray ionization ESI ; Multidimensional separation; Electrochemical manipulation; Mass spectrometry MS ; Capillary electrophoresis CE ; Microdevice; Microfabrication; Micro total analysis system μ-TAS ; Analytisk kemi; NATURAL SCIENCES Chemistry Analytical chemistry; NATURVETENSKAP Kemi Analytisk kemi;

    Abstract : The analysis of low abundant biological molecules is often challenging due to their chemical properties, low concentration and limited sample volumes. Neuropeptides are one group of molecules that fits these criteria. Neuropeptides also play an important role in biological functions, which makes them extra interesting to analyze. READ MORE
