New Zeolitic Imidazolate Framework‐Derived N‐Doped Carbon LiCl Composites for Sorption Thermal Batteries Utilizing Solar Energy

Carbon Energy, EarlyView.
New hierarchical ZIF‐derived nitrogen‐doped carbons (ZDCs) impregnated with LiCl are promising materials for sorption thermal batteries utilizing solar energy. This study examines the structural properties of ZDCs, the effect of LiCl loading, the enhancement of hydrothermal stability by nanoporous carbon, and the water adsorption properties of a series

Geometry‐Based Neural‐Network Prediction of Electron Localization Function Topology in Dense Hydrogen

Chemistry – A European Journal, EarlyView.
We present a machine‐learning framework that predicts the electron localization function (ELF) of dense hydrogen directly from atomic geometry, bypassing explicit electronic‐structure calculations. Trained on ab initio data for fluid hydrogen across multiple pressures, the model achieves high accuracy and reveals pressure‐dependent nonlocal ...

Numerical Solutions Of The Nonlocal Problems For The Diffusion Partial Differential Equations

Ibn Al-Haitham Journal for Pure and Applied Sciences, 2017
    In this work, we use the explicit and the implicit finite-difference methods to solve the nonlocal problem that consists of the diffusion equations together with nonlocal conditions.

Minimum and comparison principles for semilinear nonlocal reaction–diffusion equations

Boundary Value Problems
We consider second-order linear parabolic partial differential inequalities that include nonlocal zeroth-order quantities. For these, we establish minimum principles that highlight the interplay between the regularity of their coefficients, the growth ...

A uniqueness result for an inverse problem in a space-time fractional diffusion equation

Electronic Journal of Differential Equations, 2013
Fractional (nonlocal) diffusion equations replace the integer-order derivatives in space and time by fractional-order derivatives. This article considers a nonlocal inverse problem and shows that the exponents of the fractional time and space ...

Boundary fluxes for nonlocal diffusion

Journal of Differential Equations, 2007
Nous étudions un opérateur de diffusion non local dans un domaine lisse borné prescrivant le flux à travers la frontière. Ce problème peut être considéré comme une généralisation du problème habituel de Neumann pour l'équation de la chaleur. Tout d'abord, nous prouvons l'existence, l'unicité et un principe de comparaison.

Imidazolium Modified UiO‐67 Metal‐Organic Frameworks for CO2 Adsorption

European Journal of Inorganic Chemistry, EarlyView.
CO2 sorption in UiO‐67 and its imidazolium‐functionalized derivatives is examined with emphasis on the role of different counterions. Structural characterization and spectroscopic studies provide insight into how functionalization affects pore environments and CO2 interactions.

Assessing and Explaining Human–Nature Coordination at the County Scale in China: Combining an Interpretable Spatiotemporal Graph Neural Network and Difference‐In‐Differences

Land Degradation &Development, EarlyView.
ABSTRACT Coordinating high‐intensity human activities with fragile ecosystems remains a major challenge for global sustainability. Accurate assessment of human–nature coordination (HNC) is critical, yet county‐level variations, underlying drivers, and responses to ecological zoning have seldom been examined simultaneously within a unified framework. We
