The two-dimensional Kolmogorov-Smirnov test [PDF]

open access: yes, 2007
Goodness-of-fit statistics measure the compatibility of random samples against some theoretical probability distribution function. The classical one-dimensional Kolmogorov-Smirnov test is a non-parametric statistic for comparing two empirical ...

Kinematics of interacting solitons in two-dimensional space [PDF]

open access: yes, 2020
A simple kinematic approach to the description of the interaction between solitons is developed. It is applicable to both integrable and non-integrable two-dimensional models, including those commonly used for studying the surface and internal oceanic ...

An analytical, phenomenological and numerical study of geophysical and magnetohydrodynamic turbulence in two dimensions [PDF]

open access: yes, 2013
In this thesis I study a variety of two-dimensional turbulent systems using a mixed analytical, phenomenological and numerical approach. The systems under consideration are governed by the two-dimensional Navier-Stokes (2DNS), surface quasigeostrophic

The electrical, thermal, and thermoelectric properties of black phosphorus

open access: yesAPL Materials, 2020
Black phosphorus (BP) as a two-dimensional semiconductor has attracted tremendous interest in physics, chemistry, biology, and engineering fields. BP has a thickness-dependent bandgap and high carrier mobility, and its puckered honeycomb layer structure ...

Phase‐Changing Microcapsules Incorporated with Black Phosphorus for Efficient Solar Energy Storage

open access: yesAdvanced Science, 2020
A new solar energy storage system is designed and synthesized based on phase‐changing microcapsules incorporated with black phosphorus sheets (BPs). BPs are 2D materials with broad light absorption and high photothermal performance, which are synthesized

Covalent Selenium Embedded in Hierarchical Carbon Nanofibers for Ultra-High Areal Capacity Li-Se Batteries

open access: yesiScience, 2020
Summary: Lithium selenium (Li-Se) batteries have attracted increasing interest for its high theoretical volumetric capacities up to 3,253 Ah L−1. However, current studies are largely limited to electrodes with rather low mass loading and low areal ...

Holographic Convergent Electron Beam Diffraction (CBED) Imaging of Two-dimensional Crystals

open access: yes, 2021
Convergent beam electron diffraction (CBED) performed on two-dimensional (2D) materials recently emerged as a powerful tool to study structural and stacking defects, adsorbates, atomic 3D displacements in the layers, and the interlayer distances.

Vortical control of forced two-dimensional turbulence [PDF]

open access: yes, 2013
A new numerical technique for the simulation of forced two-dimensional turbulence (Dritschel and Fontane, 2010) is used to examine the validity of Kraichnan-Batchelor scaling laws at higher Reynolds number than previously accessible with classical pseudo-
