Electric Field Enhancements and Hot Spots in Amorphous Carbon Materials

open access: yesSmall Structures, Volume 7, Issue 3, March 2026.
We unveil how atomistic morphology governs the optical response of amorphous carbon (a‐C) by combining large‐scale DynReaxMas models with the frequency‐dependent fluctuating charge method (ω$\omega$FQ). This multiscale approach reveals distinct structural “hot spots” and clarifies the structure–property relationships underlying the emergent plasmonic ...

Effects of Pyrolysis Control Parameters on the Structural Properties of Biomass‐Derived Activated Carbon Materials and Their Energy Applications

open access: yesThe Chemical Record, Volume 26, Issue 3, March 2026.
Tubular pyrolysis synthesis is a widespread method to produce activated carbons (ACs). This review focuses on the different controlling parameters of the tubular pyrolysis synthesis method and their influence on the performance of synthesized ACs, thereby considering both experimental aspects and the use of plant‐based biomasses (PBBs) as feedstock ...

An Alternative Way to Parameterizing the Nonlocal Scale Sensible Heat Flux Using the Flux Imbalance and K‐Theory Approach

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract Accurately representing the surface sensible heat flux (SHF) in Earth System Models (ESMs) is of paramount importance and challenge. This study introduces an alternative surface‐layer SHF correction scheme by modeling nonlocal scale SHF through flux imbalance (FI) prediction models while employing the conventional gradient diffusion approach ...

Signal‐to‐noise and spatial resolution in in‐line imaging. 3. Optimization using a simple model

open access: yesJournal of Synchrotron Radiation, Volume 33, Issue 2, Page 395-408, March 2026.
Geometrical magnification and X‐ray energy are optimized with respect to spatial resolution, contrast, noise, radiation dose and other image quality characteristics. The optimization is performed using a simple theoretical model of a homogeneous edge feature embedded in a bulk uniform sample, and the resulting generic analytical expressions for image ...

Disentangling the Components Shaping Aquatic Richness Over Spatial Scales in Extreme Climatic Events

open access: yesFreshwater Biology, Volume 71, Issue 3, March 2026.
ABSTRACT Species richness in a region can be partitioned into three components: (1) spatial aggregation of individuals, (2) variation in total individual density and (3) species abundance distribution (SAD). However, it remains unclear how the influence of these components on richness changes under extreme climatic events.

A Cascaded Lattice Boltzmann Model for Porous and Multi‐Layer Shallow Water Flows

open access: yesJournal of Flood Risk Management, Volume 19, Issue 1, March 2026.
ABSTRACT The work proposes the development of a Lattice Boltzmann (LB) Cascaded collision operator (CO) model with two unexplored main purposes: reproducing the dynamics of multilayer shallow water flows and modeling urban floods with a porosity approach.
