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.

Oscillation criteria for second-order nonlinear perturbed differential equations
Electronic Journal of Differential Equations, 2014 In this article, we study the oscillation of solutions to the nonlinear second-order differential equation $$ \Big(r(t)\psi(x(t))|x'(t)|^{\alpha-1}x'(t)\Big)' +P(t,x'(t))\psi(x(t))+Q(t,x(t))=0. $$ We obtain sufficient conditions for the oscillation

Oscillation Criteria for Second-Order Nonlinear Dynamic Equations on Time Scales
Abstract and Applied Analysis, 2012 This paper is concerned with oscillation of second-order nonlinear dynamic equations of the form on time scales. By using a generalized Riccati technique and integral averaging techniques, we establish new oscillation criteria which handle some cases ...

Nonclassicality and the concept of local constraints on the photon number distribution
, 1997 We exploit results from the classical Stieltjes moment problem to bring out the totality of all the information regarding phase insensitive nonclassicality of a state as captured by the photon number distribution p_n.

Advanced Materials, EarlyView.This study utilizes the van der Waals stacking of ferroelectric α$\alpha$‐In2Se3 to fabricate in‐plane artificial charged domain walls. These charged domain walls are electrically accessible, gate‐tunable, and show 2–9 orders of magnitude higher conductance than charged domain walls from thin film ferroelectrics, allowing their integration in field ...

Advanced Materials Interfaces, EarlyView.The Cu(II)[12‐MCCu(II)N(Shi)‐4] metallacrown complex (CuCu4) is studied to examine how geometric transformations affect magnetic coupling between copper spins by using ultraviolet photoemission spectroscopy and DFT calculations for the bulk phase and CuCu4 adsorbed on Au(111). While adsorption minimally affects tDOS, exchange coupling constants between

Kamenev-type oscillation criteria for second-order quasilinear differential equations
Electronic Journal of Differential Equations, 2005 We obtain Kamenev-type oscillation criteria for the second-order quasilinear differential equation $$ (r(t)|y'(t)|^{alpha-1}y'(t))'+ p(t)|y(t)|^{eta-1}y(t)=0 ,.
