Perspective: OLED Displays Singing with the Blues
Advanced Materials, EarlyView.While blue pixels consume approximately 50% of the energy of OLED display front planes, in the 25 years since their invention, 100% internal efficiency triplet‐controlled phosphorescent OLEDs have not met the stability standards necessary for their adoption.

Advanced Materials, EarlyView.We show a giant, bias‐field free, deterministic, spin‐orbit‐torque switching of perpendicular hard magnets with HC over 1.3 T. By combining the three‐fold 3m symmetry from topological insulator surface states with the rectangular mm2 symmetry from the 2 x 1 intercalation in Cr3Te4, the interface symmetry is significantly reduced into a unidirectional m

Strong-viscosity Solutions: Semilinear Parabolic PDEs and Path-dependent PDEs
, 2019 The aim of the present work is the introduction of a viscosity type solution, called strong-viscosity solution to distinguish it from the classical one, with the following peculiarities: it is a purely analytic object; it can be easily adapted to more ...

Toward a Consensus Characterization Protocol for Organic Thermoelectrics
Advanced Materials, EarlyView.We advocate a common consensus on accurate and standardized reporting of performance metrics in the field of organic thermoelectrics. We summarize prevalent issues in the literature and propose a pre‐submission checklist to support the publication of reproducible results.

Degenerate singular parabolic problems with natural growth [PDF]
Opuscula MathematicaIn this paper, we study the existence and regularity results for nonlinear singular parabolic problems with a natural growth gradient term \[\begin{cases}\frac{\partial u}{\partial t}-\operatorname{div}((a(x,t)+u^{q})|\nabla u|^{p-2}\nabla u)+d(x,t)\frac{

Advanced Materials, EarlyView.By introducing FeCoNi medium‐entropy alloy, the bismuth sulfide (Bi2S3) material achieves a record‐high ZT of 1.1 at 773 K, owing to the solid‐states replacement reaction and the volatilization of low melting‐point metal. This strategy is also applicable to other sulfur‐based thermoelectric materials.

Cauchy problem for some fractional nonlinear ultra-parabolic equations
Electronic Journal of Differential Equations, 2016 Blowing-up solutions to nonlocal nonlinear ultra-parabolic equations is presented. The obtained results will contribute in the development of ultra-parabolic equations and enrich the existing non-extensive literature on fractional nonlinear ultra ...

Fast wavelet based algorithms for linear evolution equations [PDF]
A class was devised of fast wavelet based algorithms for linear evolution equations whose coefficients are time independent. The method draws on the work of Beylkin, Coifman, and Rokhlin which they applied to general Calderon-Zygmund type integral ...
