Abstract Boundary Delay Systems and Application to Network Flow

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 1, Page 119-129, 15 January 2026.
ABSTRACT This paper investigates the well‐posedness and positivity of solutions to a class of delayed transport equations on a network. The material flow is delayed at the vertices and along the edges. The problem is reformulated as an abstract boundary delay equation, and well‐posedness is proved by using the Staffans–Weiss theory.

Highly Efficient Simultaneous Photocatalytic Reduction of CO2 and O2 from Air Using Conjugated Microporous Polymers with Ionic Imidazolium Sites

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 1, January 2026.
In this work, we reported the rational design of two ionic conjugated microporous polymers for efficient simultaneous photocatalytic reduction of CO2 and O2 from air under mild conditions. Efficient photocatalytic reduction of CO2 is crucial to decrease the atmospheric concentration of CO2.

A Force‐Based Beam‐Column Element With Selective Gradient‐Inelasticity for Softening Materials in 3‐Dimensional Nonlinear Analysis

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 1, Page 26-45, January 2026.
ABSTRACT Fiber‐based beam‐column elements featuring an effective material constitutive law with softening can capture the degrading response of structural members under extreme loading. However, these elements exhibit strain localization and mesh divergence, which impedes their accuracy.
