High‐Rate and Selective Conversion of Low‐Concentration Carbon Dioxide to Carbon Monoxide Using a Carbon Nanotube‐Supported Molecular Electrocatalyst

Small, EarlyView.
With significantly enhanced accessibility, optimized CO2 affinity, and CO2 adsorption capacity of CoPc active sites, the molecularly dispersed MWCNT|CuPc‐CoPc electrodes realize efficient single‐pass conversion of CO2 to CO, yielding a high CO yield of 65.7 ± 2.3% and an energy efficiency of 54.8 ± 1.9% using 20% CO2 at an ampere‐level current (0.625 A)

Investigation of the impact of grain boundary hydrogen concentration on hydrogen embrittlement sensitivity of polycrystalline Fe: Molecular dynamics insights

Smart Molecules, EarlyView.
Molecular dynamics simulations were utilized to explore the influence of grain boundary hydrogen concentration on the hydrogen embrittlement sensitivity of polycrystalline iron. This graphical abstract visualizes the corresponding microstructural evolutions, with results demonstrating that elevated hydrogen concentration reduces the yield and ultimate ...

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

steel research international, EarlyView.
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, EarlyView.
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, EarlyView.
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 ...
