  2. 1. Mass Spectrometry with Electrospray Ionization from an Adjustable Gap

    Author : Patrik Ek; Åsa Emmer; Johan Roeraade; Per M. Claesson; Ulrika Nilsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electrospray ionization; mass spectrometry; nanoelectrospray; ESI; MS; chip; emitter; gap; liquid bridge; nozzle; peptides; Analytical chemistry; Analytisk kemi;

    Abstract : In this thesis the fabrication and analytical evaluation of two new electrospray emitters utilized for mass spectrometry analysis is presented. The emitters are based on a new concept, where the spray orifice can be varied in size. The thesis is based on two papers. All present-day nanoelectrospray emitters have fixed dimensions. READ MORE

  4. 2. Advancing portable, aqueous drug delivery to the human lung

    Author : Torben Last; Göran Stemme; Niclas Roxhed; Claus-Michael Lehr; KTH; []

    Abstract : Lung disease profoundly impacts human health: many lung diseases are currently without cure and require continued treatment. Due to their ease of use and integration into the daily routine, portable inhalers are the preferred treatment option for patients. READ MORE

  5. 3. Engineering Ceramics for Tribological Systems. Manufacture, Properties and Testing

    Author : Lars Kahlman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal wear; ceramic composite; face seal; engineering ceramic; erosion; hybrid bearing; thermal spalling; lubrication; tribology; abrasive waterjet; abrasive wear;

    Abstract : A broad range of commercial and experimental grades of ceramics and ceramic composites was tested in various model tests and simplified component tests. The tests were done to establish important microstructural features, friction and wear mechanisms. READ MORE

  6. 4. Additive Manufacturing and Integration of 3D MEMS using Ultrafast Lasers and Magnetic Assembly

    Author : Simone Pagliano; Frank Niklaus; Göran Stemme; Gijs Krijnen; KTH; []
