Moiré‐Induced Symmetry Breaking of Charge Order in van der Waals Heterostructures

open access: yesAdvanced Materials, EarlyView.
A uniaxial moiré potential in misfit (MS)1+δTaS2 heterostructures selectively reshape charge order: the embedded 1H‐TaS2 layer hosts an incommensurate charge‐density wave, fragmented into nanometer domains and stripped of threefold symmetry. Superconductivity, however, remains uniform and fully gapped, revealing heterosymmetry stacking as a selective ...

Moiré Phase Mapping in Twisted Bilayer Liquid Crystals with Reconfigurable Light Polarization States

open access: yesAdvanced Materials, EarlyView.
Twisted bilayer liquid crystals are developed by vertical stacking assembly of two liquid crystals having designer domains and optical properties. These moiré‐symmetry, twisted liquid crystals demonstrate reconfigurable polarization states, moiré patterns and phases controlled by twist angles, providing a route to design active optical devices for ...

Large solutions of elliptic systems of second order and applications to thebiharmonic equation

open access: yesDiscrete and Continuous Dynamical Systems, 2012
In this work we study the nonnegative solutions of the elliptic system Δu=|x|^{a}v^δ, Δv=|x|^{b}u^μ in the superlinear case μδ>1, which blow up near the boundary of a domain of R^{N}, or at one isolated point. In the radial case we give the precise behavior of the large solutions near the boundary in any dimension N.

Sustainable Plant‐Based Water Repellent Coatings Using Hydrophobic Pine and Palm Pollen

open access: yesAdvanced Materials Interfaces, EarlyView.
A novel formulation strategy for creating superhydrophobic coatings using plant‐derived waxes and chemically treated pine and palm pollen. By employing acid modification, the hydrophobicity of the pollen surface is enhanced, resulting in water contact angles exceeding 150°.

In Situ Two‐Dimensional Residual Stress Characterization of Thin Films

open access: yesAdvanced Materials Technologies, EarlyView.
An integrated in situ curvature metrology platform combining speckle‐based curvature optical metrology (SCOM) with multi‐beam optical sensors (MOS) enables spatially resolved two‐dimensional curvature mapping of thick sputtered coatings. The SCOM technique provides excellent agreement with MOS while providing an extended measurable curvature range ...

Viscosity Solutions of Nonlinear Systems of Degenerated Elliptic Equations of Second Order

open access: yesZeitschrift für Analysis und ihre Anwendungen, 2000
In this paper, we discuss the viscosity solutions of Dirichiet problem for weakly coupled systems of fully nonlinear second order degenerated elliptic equations. We prove the existence, uniqueness and continuity of solutions by Perron’s method combined with the technique of coupled solutions.

Upscaling Pulsed Laser Fragmentation in Liquids by Advanced Free‐Flow Setups

open access: yesAdvanced Materials Technologies, EarlyView.
Advanced flow setups providing thin colloid films are introduced to upscale pulsed laser fragmentation in liquids for sustainable nanoparticle synthesis. Their potential is demonstrated by yielding remarkably small ZnO nanoparticles of <7 nm. Numerical simulations complement the study, revealing that the superior performance can be attributed to ...

Constructive Sobolev gradient preconditioning for semilinear elliptic systems

open access: yesElectronic Journal of Differential Equations, 2004
We present a Sobolev gradient type preconditioning for iterative methods used in solving second order semilinear elliptic systems; the n-tuple of independent Laplacians acts as a preconditioning operator in Sobolev spaces.
