   Abstract : Flash X-ray Imaging (FXI) at X-ray Free Electron Lasers (XFELs) is a promising technique that permits the investigation of the 3D structure of molecules without the need for crystallization, by diffracting on single individual sample particles.In the past few years, some success has been achieved by using FXI on quite large biological complexes (40 nm-1 μm in diameter size).

   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; coherent diffractive X-ray imaging; lensless imaging; coherent X-ray diffractive imaging; flash diffractive imaging; single particle imaging; aerosol injection; electrospray injection; substrate-free sample delivery; carboxysome; phase retrieval; X-ray diffraction software; X-ray free-electron laser; XFEL; FEL; CXI; CDI; CXDI; FXI;

   Abstract : The newly emerging technology of X-ray free-electron lasers (XFELs) has the potential to revolutionise molecular imaging. XFELs generate very intense X-ray pulses and predictions suggest that they may be used for structure determination to atomic resolution even for single molecules. READ MORE

5. 3. Synchrotron-based characterization of mechanobiological effects on the nanoscale in musculoskeletal tissues

   Author : Isabella Silva Barreto; Avdelningen för Biomedicinsk teknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanoscale; microscale; mechanical properties; synchrotron; x-ray imaging; collagen; hydroxyapatite; biomechanics; experimental mechanics; x-ray tomography; small-angle x-ray scattering SAXS ; wide-angle x-ray scattering WAXS ; x-ray fluorescence XRF ; small-angle x-ray scattering tensor tomography SASTT ; Fourier-transform infrared spectroscopy FTIR ; polarized light microscopy PLM ; bone development; Achilles tendon; tendon healing;

   Abstract : Collagen is the main organic building block of musculoskeletal tissues. Despite collagen being their smallest load bearing unit, these tissues differ significantly in mechanical function and properties. A major factor behind these differences is their hierarchical organization, from the collagen molecule up to the organ scale. READ MORE

6. 4. Small-Animal Imaging with Liquid-Metal-Jet X-Ray Sources

   Author : Daniel Larsson; Hans Hertz; Anna Burvall; David Paterson; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; X-ray; x-ray imaging; small animal; phase contrast; tomography; Fysik; Physics;

   Abstract : Small-animal x-ray imaging is an important tool for medical research. The penetration power of x-rays makes it possible to investigate the 3D structure of small animals and other thick biological samples by computed tomography (CT). READ MORE

7. 5. An X-ray LogScanner : a tool for control of the sawmill process

   Author : Stig Grundberg; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

   Abstract : Wood is a biological material with great variability. Every piece of wood is a unique individual. The great challenge in the wood products manufacturing process has always been to select pieces of wood with properties that fulfil the product requirements. READ MORE
