Elliptic stochastic partial differential equations with two reflecting walls [PDF]
arXiv, 2014 In this article, we study elliptic stochastic partial differential equations with two reflect- ing walls h1 and h2, driven by multiplicative noise. The existence and uniqueness of the solutions are established.

Advanced Materials, EarlyView.The rise of lead halide perovskite semiconductors has enabled high‐performance LEDs with internal quantum efficiencies approaching 100%. In order to further enhance the external quantum efficiencies limited by light outcoupling effects, in this account, the strategies for reducing energy dissipation through the substrate, waveguide, and evanescent ...

Advanced Materials, EarlyView.This article investigates the micromechanics of bamboo epidermis, focusing on how anisotropic silica particle distributions enhance toughness. By integrating experimental imaging, 3D printing, and generative AI, the study develops bio‐inspired particle‐reinforced composites with mechanical properties akin to bamboo.

Chiroferromagnetic Quantum Dots for Chiroptical Synapse (ChiropS)
Advanced Materials, EarlyView.Chiroptical activity is enhanced by up to 0.003 in the g‐factor through the induction of ferromagnetism in quantum dots. A chiroptical neuromorphic synapse, composed of chiroferromagnetic quantum dots, generates different synaptic weights from multiple wavelengths and circularly polarized light.

Moisture‐Dependent Vibrational Dynamics and Phonon Transport in Nanocellulose Materials
Advanced Materials, EarlyView.Uptake of water in cellulose play an important role in modulating the structure and phonon transport. This study reports how moisture‐dependent structural modification relates to the vibrational dynamics and phonon transport and scattering of nanocellulose using inelastic neutron scattering and wide angle X‐ray scattering.

The Neumann Boundary Problem for Elliptic Partial Differential Equations with Nonlinear Divergence Terms [PDF]
arXiv, 2018 We prove the existence and uniqueness of weak solution of a Neumann boundary problem for an elliptic partial differential equation (PDE for short) with a singular divergence term which can only be understood in a weak sense. A probabilistic approach is applied by studying the backward stochastic differential equation (BSDE for short) corresponding to ...

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 ...

Broadband Chiroptics with Twist‐stacked Hyperbolic Conducting Polymer Thin Films
Advanced Materials, EarlyView.Anisotropic conducting polymer films can exhibit optical hyperbolic properties which here are found connected to large birefringence and linear dichroism. Off‐axis twist‐stacking of only two such subwavelength films can therefore enable large and broadband circular dichroism (CD), with CD bandwidth closely related to the hyperbolic bandwidth. The study

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.
