Here we present a new approach to diffraction imaging of amyloid fibrils, combining a freestanding graphene support and single nanofocused X-ray pulses of femtosecond duration from an X-ray free-electron laser. Due to the very low background scattering fro ...

The integration of customer behavioral models in optimization provides a better understanding of the preferences of clients (the demand) to policy makers while planning for their systems (the supply). On the one hand, these preferences are formalized with ...

'Seeing' Atoms: The Crystallographic Revolution

Dieter Schwarzenbach

Laue's experiment in 1912 of the diffraction of X-rays by crystals led to one of the most influential discoveries in the history of science: the first determinations of crystal structures, NaCl and diamond in particular, by W. L. Bragg in 1913. For the fir ...

Closed-form expressions for modeling diffraction at printed dipole-based FSS

Juan Ramon Mosig, Maria Garcia Vigueras

This paper presents analytical expressions to model the diffraction of plane-waves at planar 2-D distributions of printed dipoles. In contrast to other available analytical or quasi-analytical models, this approach rigorously captures the main underlying p ...

Influence of reflecting walls on edge diffraction simulation in geometrical acoustics

Dirk Schröder

Edge diffraction can be introduced into Geometrical Acoustics mainly by three models: detour-based, energetic and wave-based diffraction models. In the past, we thoroughly compared Maekawa's detour law, the uncertainty relation based diffraction method and ...

The success story of crystallography

Dieter Schwarzenbach

Diffractionists usually place the birth of crystallography in 1912 with the first X-ray diffraction experiment of Friedrich, Knipping and Laue. This discovery propelled the mathematical branch of mineralogy to global importance and enabled crystal structur ...

Compatible Component Selection Under Uncertainty Via Extended Constraint Satisfaction Approach

Paul Xirouchakis, Duck Young Kim

This paper deals with compatible component selection problems, where the goal is to find combinations of components satisfying design constraints given a product structure, component alternatives available in design catalogue for each subsystem of the prod ...

High-resolution hard-x-ray microscopy using second-order zone-plate diffraction

Giorgio Margaritondo

Odd-order diffraction of zone plates (ZPs) is already used for x-ray microscopy but the potential offered by even-order diffraction must still be fully exploited. Width differences between lines and interline spaces transfer intensity from odd-order to eve ...
