AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
The present invention relates to an interferometer for x-rays, in particular hard x-rays, for obtaining quantitative x-ray images from an object, comprising: a) an x-ray source, preferably a standard polychromatic x-ray source, b) a diffractive beam splitt ...
New charged cyclometalated iridium(III) complexes Ir(ppy)2(L) [ppy = 2-phenylpyridine; L = bis(pyrazol-1-yl)methane (for 1); L = bis(3,5-dimethylpyrazol-1-yl)methane (for 2)] were synthesized and their electrochemical and photophysical properties st ...
We present simulations of the 21-cm signal during the epoch of reionization. We focus on properly modeling the absorption regime in the presence of inhomogeneous Wouthuysen-Field effect and X-ray heating. We ran radiative transfer simulations for three ban ...
A review. The state of the art in the detn. of structures with ultrafast electrons and x-rays is highlighted. Perspectives and reflections on the principles, techniques, and methods are provided, and on applications from different disciplines, with some fo ...
X-rays, the key ingredient of radiology, are still primarily produced with the mechanism discovered by Rontgen over one century ago. A different approach, however, is becoming increasingly important: the use of synchrotron sources based on fast-moving elec ...
Dynamic energy due to ultimate limit state relevant traffic scenarios may completely be dissipated by plastic deformations without failure of the bridge element. If the structure shows significant strain hardening behaviour, the maximum static effect is al ...
The formation of colloidal unmodified (naked) gold nanoparticles is investigated by irradiation of a precursor solution with X-rays from a synchrotron source. An interesting morphological evolution as a function of exposure time, from cross-linked network- ...
A bundled electron beam (BEB) (14) is controlled regarding its excursion in its direction by two pairs of plate electrodes (17.1,17.2;18.1,18.2) that operate vertically to each other. The BEB can use appropriate control of these plate electrodes to scan an ...
We demonstrate with practical tests that a photoelectron emission microscope (PEEM) can be advantageously used as a high-lateral-resolution detector of X-rays. The advantages of this approach are discussed, in particular for coherence-based techniques. (C) ...
One century after their discovery and first application to radiology, X-rays are finally achieving coherence. The potential impact on radiological imaging is extremely important, with significant social repercussions. These exciting developments are the fi ...
