Fast Simulation of Wide‐Angle Coherent Diffractive Imaging

open access: yesLaser &Photonics Reviews, EarlyView.
The propagation multi‐slice Fourier transform method is introduced as an accurate and efficient approach for describing light scattering for arbitrarily shaped objects. Its exceptional suitability for simulating coherent diffractive imaging of nanoparticles in the XUV and soft X‐ray range is demonstrated.

Development of Fibrillar Morphology in a Polypropylene Under Time‐Dependent Shear Flow

open access: yesMacromolecular Materials and Engineering, EarlyView.
The effects of isothermal, non‐constant flow on morphology development in iPP are studied. Two tests, applying the same total work but with different time evolution of the shear rate, are considered. The pattern of shear flow, not just the intensity, influences morphology.

Existence Analysis of a Three‐Species Memristor Drift‐Diffusion System Coupled to Electric Networks

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT The existence of global weak solutions to a partial‐differential‐algebraic system is proved. The system consists of the drift‐diffusion equations for the electron, hole, and oxide vacancy densities in a memristor device, the Poisson equation for the electric potential, and the differential‐algebraic equations for an electric network.
