MOF‐Derived Porous Iron Oxide With Optimized Photothermal and Interfacial Properties for High‐Fidelity LDI‐MS Metabolomics and Digital Traceability of Tobacco Leaves

SmartMat, Volume 7, Issue 4, August 2026.
A porous iron oxide nanomaterial is developed as a high‐performance matrixes for laser desorption/ionization mass spectrometry, enabling rapid acquisition of high‐quality metabolic fingerprints from tobacco leaves. Integrated with Random Forest, it accurately discriminated leaves by stalk positions and geographical origins, and further identified an ...

Direct Observation of Interfacial Charge Transfer in Water Reduction at a Cu2O Photocathode by In Situ Near‐Field Heterodyne Transient Grating Spectroscopy

Small Science, Volume 6, Issue 8, August 2026.
Near‐field heterodyne transient grating spectroscopy directly resolves reduction‐related electron dynamics at a Cu2O photocathode under water‐reduction conditions. A 1.33 μs interfacial electron‐transfer process is identified and validated by isotope‐effect measurements and complementary analyses, while temperature‐dependent measurements reveal a ...

Recycling‐Induced Copper Contamination of a 42CrMo4 Quench and Tempering Steel—Scaling and Susceptibility to Hot Shortness

steel research international, Volume 97, Issue 8, Page 4261-4269, August 2026.
In this study, the susceptibility to copper‐induced hot shortness of the alloy 42CrMo4 is investigated by different hot tensile tests, as well as by a detailed analysis of the formed oxidation products. While an enrichment of metallic copper and a penetration of the grain boundaries are observed, no critical reduction of the tensile test properties can

Influence of Hydrogen Fuel Mixtures on the Oxide Scale Formation of Low‐Carbon Steels in Reheating Furnace Conditions

steel research international, Volume 97, Issue 8, Page 4193-4206, August 2026.
This work illustrates how substituting natural gas with hydrogen as fuel in the reheating furnace will influence the oxide scale formation on the steel surface. Thermogravimetric analysis and characterization techniques are used to investigate oxidation behavior and the formation of oxide phases.

Using Thermodynamics and Microstructure to Mitigate Overfitting in Pellet Reduction Models

steel research international, Volume 97, Issue 8, Page 4097-4107, August 2026.
A in time and space discretized, thermodynamically sound model for direct reduction of iron oxide pellets is described. The number of fitting parameters is drastically reduced compared to existing models. Nevertheless, fitting kinetic parameters based on conversion degree data alone leads to overfitting, which can be mitigated by correlating the ...
