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

open access: yesChemistry – 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 ...

A New Spin on Photocatalysis: Vortex Fluidic‐Driven Photooxidations Enabled by Solution‐Processable Microporous Polymers

open access: yesChemistry – A European Journal, EarlyView.
Newly developed polymers with intrinsic microporosity (PIMs) were combined with benzo[c][1,2,5]thiadiazole (BTZ) to be used as visible light photocatalytic coatings on the Vortex Fluidic Device (VFD). The VFD's rapid rotation and continuous flow capabilities enhanced singlet oxygen and superoxide radical reactions, achieving a dramatic eightfold ...

Investigating the Electrochemical Double Layer with Quantum‐Chemical Simulations and Implicit Solvation Models

open access: yesChemistry – A European Journal, EarlyView.
ESM‐RISM is applied to model electrochemical interfaces and benchmarked against Poisson–Boltzmann and molecular dynamics results. Density profiles, differential capacitance, and adsorption energetics at the gold–electrolyte interface are analyzed, highlighting the capabilities of this implicit electrolyte framework.

Spectral properties of non-local uniformly-elliptic operators [PDF]

open access: yes, 2006
In this paper we consider the spectral properties of a class of non-local uniformly elliptic operators, which arise from the study of non-local uniformly elliptic partial differential equations. Such equations arise naturally in the study of a variety of

Vibrational Circular Dichroism Spectra of 2,5‐Diaminoterephtalate Macrocycles Reveal Distant Vibrational Exciton Coupling

open access: yesChemistry – A European Journal, EarlyView.
The energy level diagrams for the ν(C═O) and the δ(N─H) vibrations, resulting of combining in‐phase and out‐of‐phase modes on the basis of their local symmetries, was built by applying the exciton coupling theory to a new class of chiral macrocycles, based on the 2,5‐diaminoterephthalate scaffold.

Lie symmetry analysis, exact solutions and conservation laws for the time fractional modified Zakharov–Kuznetsov equation

open access: yesNonlinear Analysis, 2017
In this work, Lie symmetry analysis (LSA) for the time fractional modified Zakharov–Kuznetsov (mZK) equation with Riemann–Liouville (RL) derivative is analyzed.

Nitrogen‐Site Isomerism Unlocks Exciton Dissociation in Vinylene‐Linked COF‐Based Photocatalysts

open access: yesEcoEnergy, EarlyView.
Two regioisomeric vinylene‐linked covalent organic frameworks (COFs) constructed from diazine units with different nitrogen positions are developed for photocatalytic hydrogen evolution reaction (HER). Although structurally similar, the isomeric COFs exhibit distinct electron distribution and charge‐separation behaviors, leading to a more than twofold ...

Families of Rational and Semirational Solutions of the Partial Reverse Space-Time Nonlocal Mel′nikov Equation

open access: yesComplexity, 2020
Exact periodic and localized solutions of a nonlocal Mel′nikov equation are derived by the Hirota bilinear method. Many conventional nonlocal operators involve integration over a spatial or temporal domain.
