How Amino Acids Intercalate in CaFe Layered Double Hydroxides: A Combined RIXS and NEXAFS Study

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Intercalation of amino acids in layered double hydroxides offers a road to functional (bio)catalysts. With resonant soft x‐ray spectroscopy we probe the electronic structure of these systems and observe activation and passivation of electronic states as well as bond formation between the amino acid and the LDH upon intercalation.

Understanding the active site structures and achieving catalytic activity tuning of atomically dispersed FeN4 sites for oxygen reduction reaction

open access: yesChemPhysChem, Accepted Article.
Atomically dispersed Fe‐N‐C catalysts with high oxygen reduction reaction (ORR) activity have attracted great attention since the last decade. Due to its comparable ORR activity and low material cost, it is a promising platinum‐group metal (PGM) free catalyst that can replace the commercialized Pt/C materials; furthermore, it can facilitate the ...

Mechanical property variation mechanisms of granite subjected to real‐time high temperatures and subsequent cooling treatment

open access: yesDeep Underground Science and Engineering, EarlyView.
This study investigates the coupled thermo‐mechanical behavior of granite during heating and cooling through a combination of laboratory tests and finite element analysis. The thermal conductivity, mineral composition, mass loss rate, micro‐crack observation, and thermal fracture characteristics of granite under various temperature conditions are ...

Investigation on the Calibration of Numerical Models for Cast Steel Replaceable Modular Yielding Links in Steel Eccentrically Braced Frames

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT A new generation of yielding links, referred to as cast steel replaceable modular yielding links (CMLs), was recently validated through extensive large‐scale testing, to enhance the seismic performance of steel eccentrically braced frames (EBFs). The effective use of CMLs relies on accurately evaluating the seismic response of the EBF systems,

Modeling Nonlinear Cyclic Load–Deformation Response of Corrosion‐Damaged Reinforced Concrete Columns

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This study presents a lumped plasticity modeling method for simulating the nonlinear load–deformation response of corroded reinforced concrete (RC) columns with rectangular and circular cross‐sections. The proposed modeling method utilizes an extended column database to enhance the robustness of the database and considers cyclic degradation ...

A Critical Overview of Common Foodborne Toxicants and Methods for Their Reliable Detection

open access: yesFood Frontiers, EarlyView.
ABSTRACT Food is an essential commodity for human health. However, toxicants such as mycotoxins, heavy metals, acrylamide, and pesticides can be present in food either naturally or through processing, packaging, or some anthropogenic activities. A thorough review of carefully selected studies revealed that climate change and pandemics have led to an ...
