Hierarchically structured bioinspired nanocomposites

Nature Materials, 2022
Next-generation structural materials are expected to be lightweight, high-strength and tough composites with embedded functionalities to sense, adapt, self-repair, morph and restore. This Review highlights recent developments and concepts in bioinspired nanocomposites, emphasizing tailoring of the architecture, interphases and confinement to achieve ...

Strategies for Improving the Stability of Tin‐Based Perovskite (ASnX3) Solar Cells

Advanced Science, 2020
Although lead‐based perovskite solar cells (PSCs) are highly efficient, the toxicity of lead (Pb) limits its large‐scale commercialization. As such, there is an urgent need to find alternatives. Many studies have examined tin‐based PSCs.

Hierarchical Segmentation of Complex Structures [PDF]

2010 20th International Conference on Pattern Recognition, 2010
We present an unsupervised hierarchical segmentation algorithm for detection of complex heterogeneous image structures that are comprised of simpler homogeneous primitive objects. An initial segmentation step produces regions corresponding to primitive objects with uniform spectral content.

HIERARCHICAL STRUCTURE OF THE UNIVERSE

Odessa Astronomical Publications, 2018
The modern understanding of the structure of the Universe is discussed. The Solar System is viewed as an ordinary planetary system. The neighbourhood of the Sun is specified starting with the nearest stars and nearby clusters and working outward through ...

Hierarchical structure in the trace formula*

Journal of Physics A: Mathematical and Theoretical, 2022
Abstract Guztwiller’s trace formula is central to the semiclassical theory of quantum energy levels and spectral statistics in classically chaotic systems. Motivated by recent developments in random matrix theory and number theory, we elucidate a hierarchical structure in the way periodic orbits contribute to the trace formula that has ...

How can we derive hydration water dynamics with incoherent neutron scattering and molecular dynamics simulation?

Biophysics and Physicobiology, 2019
Incoherent neutron scattering (INS) is one of the useful experimental methods for studying protein dynamics at the pico-nanosecond timescale. At this timescale, protein dynamics is highly coupled with hydration, which is observed as protein dynamical ...
