Adsorption Mechanisms and AI‐Driven Discovery of Biomass‐Based CO2 Sorbents

open access: yesSmall, EarlyView.
This review analyzes recent advances in biomass‐derived activated carbons for CO2 capture. It highlights the influence of precursors, activation methods, and surface modifications on adsorption performance. The integration of AI‐driven approaches for material optimization is discussed.

Frequency‐Multiplexed Parallel Differentiation in Subwavelength Planar Metastructure

open access: yesSmall Structures, EarlyView.
A metastructure processing unit performs frequency‐multiplexed parallel differentiation within a planar subwavelength structure. By optimizing the design of pixel metamaterial, the device enables real‐time edge detection on multiple input signals, demonstrating high computational density and compactness for integrated electromagnetic signal processing.

Rate‐type and integral‐type sectional analysis for time‐dependent response with the fib Model Code 2020

open access: yesStructural Concrete, EarlyView.
Abstract This study examines the time‐dependent behavior of reinforced and prestressed concrete structures using integral‐ and rate‐type formulations, applying the concrete creep and steel relaxation models from the fib Model Code 2020. The stress–strain law for aging concrete is expressed by a second‐order differential equation, but a single rate‐type
