Time-resolved X-ray phase-contrast tomography
(2018-06-27)X-ray tomography allows to obtain the three-dimensional (3d) structure of weakly interacting objects, such as tissue samples in biomedical imaging or nanoscale structures in materials science, with high spatial resolution. ... -
Ein Verfahren zur Herstellung zweidimensionaler Röntgenwellenleiter
(2013-07-15)As X-ray beams only weakly interact with matter, conventional refracting optics are not suitable for the use in this energy range. Instead, different approaches replace conventional optics in the X-ray regime, one of them ... -
Vesicle Adhesion, Fusion, and Neurotransmitter Uptake Studied by Small-Angle X-ray Scattering
(2022-02-15)Synaptic neurotransmission is a highly complex and crucial process in the communication between neuronal cells, and is thus directly related to the complex functions of the neural system, including information processing ... -
