Thermally Activated Swelling and Wetting Transition of Frozen Polymer Brushes:a New Concept for Surface Functionalization

Advanced Materials, EarlyView.
A novel approach is introduced that leverages polymer phase transitions to modulate brush behavior. The oleophilic bottle brush system exhibits two distinct melting transitions—bulk and surface—enabling a two‐stage swelling and wetting transition.

Chaos in dynamical systems by the Poincaré-Melnikov-Arnold method [PDF]

, 1984
Methods proving the existence of chaos in the sense of Poincaré-Birkhoff-Smale horseshoes are presented. We shall concentrate on explicitly verifiable results that apply to specific examples such as the ordinary differential equations for a forced ...

Precision Synthesis of a Single Chain Polymorph of a 2D Solid within Single‐Walled Carbon Nanotubes

Advanced Materials, EarlyView.
The precise synthesis of 1D materials has enabled the discovery of physical properties only accessible in length scales close to the atomic scale. Herein, it is demonstrated that encapsulation within single‐walled carbon nanotubes with matching diameters leads to a stoichiometric quasi‐1D van der Waals polymorph of a 2D pnictogen chalcogenide, Sb2Te3 ...

Numerical computation of transonic flow governed by the full-potential equation [PDF]

Numerical solution techniques for solving transonic flow fields governed by the full potential equation are discussed. In a general sense relaxation schemes suitable for the numerical solution of elliptic partial differential equations are presented and ...

Eigenfunction expansions for a fundamental solution of Laplace's equation on $\R^3$ in parabolic and elliptic cylinder coordinates

, 2012
A fundamental solution of Laplace's equation in three dimensions is expanded in harmonic functions that are separated in parabolic or elliptic cylinder coordinates. There are two expansions in each case which reduce to expansions of the Bessel functions $

Proposing Altermagnetic‐Ferroelectric Type‐III Multiferroics with Robust Magnetoelectric Coupling

Advanced Materials, EarlyView.
Multiferroics are highly sought after for advanced technological applications. Here, a novel class of type‐III multiferroics is proposed, where ferroelectricity and altermagnetism are inherently interlocked by crystal symmetry, setting them apart from conventional multiferroics. The ferroelectric switching is shown to fully invert the spin polarization

Quasiconformal solutions to elliptic partial differential equations

Annales Fennici Mathematici, 2023
In this paper, we assume that \(G\) and \(\Omega\) are two Jordan domains in \(\mathbb{R}^n\) with \(\mathcal{C}^2\) boundaries, where \(n\ge 2\), and prove that every quasiconformal mapping \(f\in\mathcal{W}^{2,1+\epsilon}_{\mathrm{loc}}\) of \(G\) onto \(\Omega\), satisfying the elliptic partial differential inequality \(|L_ A[f]|\lesssim (\|Df\|^2 ...

Tailoring Robust Quantum Anomalous Hall Effect via Entropy‐Engineering

Advanced Materials, EarlyView.
Bandstructure renormalization, without (w/o) spin‐orbit interaction (SOI) (left) and with SOI (right), in the low‐energy Dirac bands of zero‐entropy (purple) and entropic (green) VCl3 monolayer (ML) with long‐range ordering (LRO). Abstract The development of quantum materials and the tailoring of their functional properties is of fundamental interest ...

Approximation of linear functionals using an hp-adaptive discontinuous Galerkin finite element method [PDF]

, 2004
We consider the problem of computing a linear functional of the solution of an elliptic partial differential equation to within a given tolerance. We drive an a posteriori error bound for the linear functional and use this as the basis of an hp-adaptive ...
