Nonlocal Integro-Differential Equations of the Second Order with Degeneration [PDF]

Mathematics, 2020
We study the solvability for boundary value problems to some nonlocal second-order integro–differential equations that degenerate by a selected variable. The possibility of degeneration in the equations under consideration means that the statements of the corresponding boundary value problems have to change depending on the nature of the degeneration ...

Directional Light Scattering In Mie‐Resonant Si Particles With Ultra‐Thin Au Shells

Advanced Optical Materials, EarlyView.
Si@Au core‐shell particles have been produced to study their ability to directionally scatter light. We found that the heavily reported particulate shells do not overlap the electric and magnetic dipoles well, where continuous shells have better overlap. Experimental analyses, including nanomaterial characterization, EELS and single‐particle dark‐field

Experimental Test of the Three‐Setting Clauser–Horne–Shimony–Holt Inequality with Nonmaximally Orbital Angular Momentum Entangled States

Advanced Photonics Research, EarlyView.
Herein, the maximum violation of the three‐setting Clauser–Horne–Shimony–Holt (CHSH) inequality using nonmaximally entangled photons with orbital angular momentum is demonstrated. By mapping the optimization problem to maximizing a triangle's perimeter inscribed in an ellipse, the experiment validates the geometric approach and highlights the ...

On the Second Order of Accuracy Stable Implicit Difference Scheme for Elliptic-Parabolic Equations

Abstract and Applied Analysis, 2012
We are interested in studying a second order of accuracy implicit difference scheme for the solution of the elliptic-parabolic equation with the nonlocal boundary condition. Well-posedness of this difference scheme is established.

Optimizing Graphene Oxide Interlayer Spacing for Zeolitic Imidazolate Framework‐8 Growth Toward Enhanced Shale Oil Separation

Advanced Science, EarlyView.
Quaternary ammonium salts are used to control the spacing between GO layers, enabling in situ growth of ZIF‐8. The resulting ZIF‐8‐GO membrane exhibits nearly complete rejection of n‐docosane in n‐hexane, solvent permeance of 16.4 ± 0.8 L m−2 h−1 bar−1, and enriches alkanes and aromatics with a molecular weight cut‐off of 310 g mol−1 in shale oil ...
