  4. 2. Nanofabrication of Diffractive Soft X-ray Optics

    Author : Magnus Lindblom; Hans M. Hertz; Erik H. Anderson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanofabrication; Zone plate; x-ray; diffractive x-ray optics; x-ray microscopy; Optics; Optik; Physics; Fysik;

    Abstract : This thesis summarizes the present status of the nanofabrication of diffractive optics, i.e. zone plates, and test objects for soft x-ray microscopy at KTH. The emphasis is on new and improved fabrication processes for nickel and germanium zone plates. READ MORE

  5. 3. Functionalized Biomaterial Surfaces by Micro- and Nanofabrication

    Author : Sarunas Petronis; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanofabrication; surface characterization; surface topography; surface chemical composition; marine biofouling; force-sensing substrates; microfabrication; surface-enhanced Raman spectroscopy; cell-surface interaction; biointerfaces; biomaterials;

    Abstract : In the field of biomaterials, well-defined nano- and micropatterns or features at material surfaces can serve both as models for investigating material-biosystem interactions and as functional features for inducing, hindering or measuring specific bioreactions or biologic responses. Important bioreactions include protein adsorption and conformation, cell attachment and function, and adhesion and function of organized tissues or whole organisms. READ MORE

  6. 4. High-Aspect Ratio Nanofabrication for Hard X-Ray Zone Plates

    Author : Karolis Parfeniukas; Ulrich Vogt; Hans Hertz; Anne Sakdinawat; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nanofabrication; x-ray optics; zone plate; tungsten; silicon; reactive ion etching; metal-assisted chemical etching; Ronchi test; Fysik; Physics;

    Abstract : Hard x-ray nanoimaging enables structural investigations of new materials for many applications. For high-resolution experiments, zone plate x-ray optics are commonly chosen.Two methods of zone plate nanofabrication are presented in this thesis.Zone plates are circular diffraction gratings with radially decreasing grating period.

  7. 5. Nanofabrication of Zone Plates for Hard X-Ray Free-Electron Lasers

    Author : Fredrik Uhlén; Ulrich Vogt; Thomas Wilhein; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; X-ray optics; Zone plates; Nanofabrication; X-ray free-electron lasers; Fysik; Physics;

    Abstract : This Thesis describes the development of hard X-ray zone plates intended for focusing radiation at X-ray free-electron lasers (XFELs). XFELs provide unprecedented brightness and zone plates which are put in the intense X-ray beam are at risk of being damaged. READ MORE
