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 ...

A note on nonlinear elliptic systems involving measures
Electronic Journal of Differential Equations, 2000 We study the existence and regularity of solutions to nonlinear elliptic systems whose right-hand side is a measure-valued function. Using a sign condition instead of structure conditions, we obtain the same as those presented by Dolzmann, Hungerbuhler ...

Advanced Materials, EarlyView.The intensive lath‐shaped Ag2Te Widmannstätten nanoprecipitates are in situ generated in SnTe via AgPbSbTe3 alloying, and align with the formation of the parallel type and twin type interfaces. These Widmannstätten nanoprecipitates effectively scatter phonons to reduce the lattice thermal conductivity, resulting in a significantly enhanced average ZT ...

Optimal boundary control for a time dependent thermistor problem
Electronic Journal of Differential Equations, 2009 An optimal control of a two dimensional time dependent thermistor problem is considered. The problem consists of two nonlinear partial differential equations coupled with appropriate boundary conditions which model the coupling of the thermistor to ...

Direct Laser Writing of Polymer Nanocomposites for Tunable Structural Color
Advanced Materials, EarlyView.Herein, direct laser writing is used to polymerize self‐assembled nanocomposite materials. Using fabrication parameters, the interparticle spacing is finely tuned beyond the thermodynamically stable state. This is exploited to generate wide gamut structural color in water.

Solutions to elliptic systems of Hamiltonian type in R^N
Electronic Journal of Differential Equations, 1999 The paper proves existence of a solution for elliptic systems of Hamiltonian type on ${mathbb R}^N$ by a variational method. We use the Benci-Rabinowitz technique, which cannot be applied here directly for lack of compactness.

On a class of semilinear elliptic systems
Journal of Mathematical Analysis and Applications, 2003 AbstractThis paper deals with the existence of positive solutions to a Dirichlet problem for the superlinear elliptic system Δu=−λf(v),Δv=−λg(u) on a ball, where λ is a positive parameter and f(0),g(0) may be negative.

Stiffening Liquid Crystal Elastomers with Liquid Crystal Inclusions
Advanced Materials, EarlyView.Incorporation of low molecular weight liquid crystals (LC) into liquid crystal elastomers (LCE) leads to a significant increase in their stiffness and output work density. Such remarkable stiffening is attributed to nanoscale phase‐separation and the formation of induced‐smectic domains in polydomain and monodomain LC‐LCEs, respectively.
