Domain Nucleation and Growth in an Epitaxially Grown Wurtzite Ferroelectric

Advanced Functional Materials, EarlyView.
Ferroelectric domain nucleation and growth in epitaxial wurtzite (Al, B, Sc)N films are visualized through in situ transmission electron microscopy. Domains initiate near the bottom electrode and propagate laterally with zigzag walls, while unswitched regions remain near the electrode interfaces.

Fractal analysis of the flour [PDF]

Journal on Processing and Energy in Agriculture, 2020
The aim of the paper was the evaluation of the microscopic, powder samples of flour by utilizing the fractal analysis. The powder particles were compared and submitted to fractal analysis. Three types of flour were studied, smooth flour, semi-flour and thick flour. The five samples of each sort of flour were tested by fractal analysis. The samples were

Designing Physical Unclonable Functions From Optically Active Materials

Advanced Materials, EarlyView.
Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.
