Responsive Polyelectrolyte Brushes in Applications: Functions, Stimuli, and Design Considerations

Advanced Materials, EarlyView.
With advances in the synthesis of polyelectrolyte brushes, these coatings of surface‐grafted chains find uses in an increasing number of applications. This review summarizes three core aspects of these brushes: how they introduce functionality to surfaces; how external stimuli influence their properties; and what practical considerations should be ...

Applications of fractal analysis to physiology [PDF]

Journal of Applied Physiology, 1991
This review describes approaches to the analysis of fractal properties of physiological observations. Fractals are useful to describe the natural irregularity of physiological systems because their irregularity is not truly random and can be demonstrated to have spatial or temporal correlation.

Fractal Analysis and Time Series Application in ZY-4 SEM Micro Fractographies Evaluation

Fractal and Fractional, 2022
SEM microfractographies of Zircaloy-4 are studied by fractal analysis and the time-series method. We first develop a computer application that associates the fractal dimension and lacunarity to each SEM micrograph picture, and produce a nonlinear ...

Real‐Time Probing of Morphological Evolution and Recrystallization During Solvent Annealing in Blade‐Coated All‐Polymer Organic Solar Cells Using In Situ X‐Ray Scattering

Advanced Science, EarlyView.
In situ grazing‐incidence X‐ray scattering and in situ UV–vis spectroscopy are being used for the first time to reveal the morphological evolution of all‐polymer solar cell (APSCs) blends during solvent vapor annealing (SVA). SVA strongly influences the recrystallization and reordering behavior of APSCs blends, successfully establishing the ...

Microstructural Origin of Nonmonotonic Piezoresistivity in Polymer Nanocomposites

Advanced Science, EarlyView.
When polymer nanocomposites are subjected to tensile loading, the electrical resistance‐strain relationship may be nonmonotonic, hampering the use of these materials in real‐world applications. This challenge is addressed through the collaborative use of physical experimentation and computer simulations, establishing the inter‐nanotube junction ...
