Positive solutions for nonlinear fractional differential equation with nonlocal boundary conditions

open access: yes, 2018
In this paper, we study the boundary value problem of a class of fractional differential equations involving the Riemann-Liouville fractional derivative with nonlocal integral boundary conditions. To establish the existence results for the given problems,

Computational Modeling of Reticular Materials: The Past, the Present, and the Future

open access: yesAdvanced Materials, EarlyView.
Reticular materials are advanced materials with applications in emerging technologies. A thorough understanding of material properties at operating conditions is critical to accelerate the deployment at an industrial scale. Herein, the status of computational modeling of reticular materials is reviewed, supplemented with topical examples highlighting ...

Hilfer–Hadamard Fractional Boundary Value Problems with Nonlocal Mixed Boundary Conditions

open access: yesFractal and Fractional, 2021
This paper is concerned with the existence and uniqueness of solutions for a Hilfer–Hadamard fractional differential equation, supplemented with mixed nonlocal (multi-point, fractional integral multi-order and fractional derivative multi-order) boundary ...

Solvability of the -Laplacian with nonlocal boundary conditions

open access: yesApplied Mathematics and Computation, 2009
Rather mild sufficient conditions are provided for the existence of positive solutions of a boundary value problem of the form[@F(x^'(t))]^'+c(t)(Fx)(t)=0,[email protected]?(0,1),x(0)-L"0(x)=x(1)-L"1(x)=0,which unify several cases discussed in the literature. In order to formulate these conditions one needs to know only properties of the homeomorphism @

A nonlinear second order problem witha nonlocal boundary condition [PDF]

open access: yesAbstract and Applied Analysis, 2006
We study a nonlinear problem of pendulum‐type for a p‐Laplacian with nonlinear periodic‐type boundary conditions. Using an extension of Mawhin′s continuation theorem for nonlinear operators, we prove the existence of a solution under a Landesman‐Lazer type condition.

Scaling Up Purcell‐Enhanced Self‐Assembled Nanoplasmonic Perovskite Scintillators into the Bulk Regime

open access: yesAdvanced Materials, EarlyView.
This study presents a scalable approach to enhancing bulk scintillators using nanoplasmonics. By integrating 100‐nm silver nanoparticles with perovskite scintillator nanocrystals in a polymer matrix, significant improvements in light yield and decay rates via the Purcell effect are achieved.
