Advanced Optical Materials, EarlyView.Blue organic light‐emitting diodes (OLEDs) comprising triplet‐harvesting emitters require the use of high‐triplet‐energy hosts and blocking layers to confine the triplet excitons to the emitter. Here, we present efficient single‐layer blue hyperfluorescent OLEDs comprising solely of a matrix‐free emissive layer between two charge‐injecting electrodes ...

Advanced Optical Materials, EarlyView.Optical and plasmonic properties of TiN and Ti(O)N thin films were tuned at the synthesis stage by modulating the oxygen pressure during room‐temperature pulsed laser deposition. Ti(O)N thin films exhibiting a highly metallic and peculiar double‐epsilon‐near‐zero (DENZ) behavior were produced.

Web-Stiffened Sandwich Structures
Journal of Applied Mechanics, 1971A model representation of a web-cored sandwich structure, which is based upon the energy principles of continuum theory while retaining the discrete nature of the webs, is studied. The determination of a second-order shear modulus, which measures local bending effects, accounts for the transverse shear deformation of the core.

Deformation of Sandwich Structure
The Journal of the Royal Aeronautical Society, 1965The purpose of this note is to present formulae, derived by stationary energy considerations, for the deflection of an arbitrary length of sandwich structure subjected to the three-point bend test, for comparison with experimental results.

Homogenization of sandwich structures
International Journal for Numerical Methods in Engineering, 2004AbstractA homogenization method is proposed for sandwich structures consisting of two plates interlaced with beams and shells in a periodic, lattice structure. The proposed method is a quasi‐continuum approach where the constitutive response is obtained from the generalized forces of the interlacing elements.

Caractérisation des structures sandwich
Étude et propriétés des métaux, 2012Les structures sandwich, de par leur capacite a allier rigidite en flexion et legerete, sont de plus en plus utilisees. Afin de choisir la structure optimale, il est essentiel de comprendre l'influence des differents parametres (materiaux et dimensions) sur les proprietes de service mais aussi sur les mecanismes d'endommagements.

Integrally Woven Sandwich-Structures
1989New technical opportunities with regard to manufacturing and mechanical properties are opened up by the development of new integrally woven sandwich structures. In these fibre constructions, two fabric layers are separated by a woven-in system of z-directional fibres. After impregnation with a resin, the double-wall fabrics form the sandwich structure.

Stability Analysis of Multilayer Sandwich Structures
AIAA Journal, 1973The finite element method is applied to the stability analysis of multilayer sandwich structures with n stiff layers and n-1 weak cores, in which each layer or core can assume different material properties, so that the concept of common shear angle is no longer applicable. A beam element, a rectangular plate element and a triangular element are used in
