Existence of solutions to three-point boundary-value problems at resonance

open access: yesElectronic Journal of Differential Equations, 2016
Using Mawhin's continuation theorem, we prove the existence of solutions for a class of nonlinear second-order differential equations in $\mathbb{R}^n$ associated with a three-point boundary conditions at resonance.

Control of Polarization and Polar Helicity in BiFeO3 by Epitaxial Strain and Interfacial Chemistry

open access: yesAdvanced Functional Materials, EarlyView.
In BiFeO3 thin films, the interplay of interfacial chemistry, electrostatics, and epitaxial strain is engineered to stabilize homohelicity in polarization textures at the domain scale. The synergistic use of a Bi2O2‐terminated Aurivillius buffer layer and a highly anisotropic compressive epitaxial strain offers new routes to control the polar‐texture ...

Periodic solutions for a kind of rayleigh equation with two deviating arguments

open access: yesElectronic Journal of Differential Equations, 2006
In this paper, we use the coincidence degree theory to establish new results on the existence of $T$-periodic solutions for the Rayleigh equation with two deviating arguments of the form $$ x''+f(x(t), x'(t))+g_{1}(t,x(t-au_{1}(t)))

Intrabandgap States Engineering in Functionalized Nanodiamond to Generate Solvated Electrons for Photocatalysis Under Solar Illumination

open access: yesAdvanced Functional Materials, EarlyView.
The negative electron affinity of diamond allows to emit highly reductive electrons. By introducing intra‐bandgap states and an optimized electron transfer mechanism by surface functionalization with Ru(bpy)3, the formation of solvated electrons is achieved upon solar irradiation.

Chiral SURMOFs for Vibrational Circular Dichroism: Multiscale Modeling and Experimental Insights

open access: yesAdvanced Functional Materials, EarlyView.
The use of solid‐state vibrational circular dichroism (VCD) for MOFs is still somewhat unexplored, and in this work, it is shown that chiral surface‐anchored MOFs (SURMOFs) grown on CaF2 provide an excellent platform for VCD. Experimental results are validated through multiscale modeling, showing strong agreement across multiple spectroscopic ...

Antiperiodic solutions for nth-order functional differential equations with infinite delay

open access: yesElectronic Journal of Differential Equations, 2016
In this work, we establish the existence and uniqueness of antiperiodic solution for a class of nth-order functional differential equations with infinite delay. The main tool in our study is the coincidence degree theory.
