On implicit impulsive Langevin equation involving mixed order derivatives
Advances in Difference Equations, 2019 In this paper, we consider a nonlocal boundary value problem of nonlinear implicit impulsive Langevin equation involving mixed order derivatives. Sufficient conditions are constructed to discuss the qualitative properties like existence and Ulam’s ...

Advanced Functional Materials, EarlyView.Clusterization‐triggered emission is realized in dilute aqueous solution by introducing imine linkages into cellulose‐based luminophores. Imine functionalization creates O/N‐rich, hydrogen‐bonded clustered microenvironments that stabilize emissive states and restrict molecular motions. Luminescence is tunable by amine type and multiplicity.

Finite difference approximations for a class of non-local parabolic equations
International Journal of Mathematics and Mathematical Sciences, 1997 In this paper we study finite difference procedures for a class of parabolic equations with non-local boundary condition. The semi-implicit and fully implicit backward Euler schemes are studied.

Energetic Offset in Organic Solar Cells‐ Importance, Confusion and Outlook
Advanced Materials, EarlyView.Energetic offsets in organic solar cells (OSCs) remain a subject of debate due to measurement‐ and lab‐dependent discrepancies. This Perspective clarifies the physical origins of these variations and identifies temperature‐dependent electro‐optical methods as a reliable approach to obtain consistent offset values.

Solving a System of 2D Burger\'s Equations using Semi-Lagrangian Finite Difference Schemes
پژوهشهای ریاضی, 2020 Introduction Following and generalizing the excellent work of Wang et al. [26], we extract here some new schemes, based on the semi-Lagrangian discretization, the modified equation theory, and the local one-dimensional (LOD) scheme for ...
