Influence of Heat Treatment Temperature on Crevice and Pitting Corrosion of UNS S32205 Duplex Stainless Steel

steel research international, EarlyView.
Heat treatments that alter the proportions of austenite and ferrite phases or induce the precipitation of phases such as sigma in duplex stainless steel UNS S32205 make it more susceptible to pitting and crevice corrosion. However, the effects of these treatments are not always evident when analyzed using the cyclic polarization technique.

In Situ Investigation of Microstructure Evolution and Stress Generation During Low‐Pressure Carburizing and Quenching by Means of Synchrotron X‐Ray Diffraction

steel research international, EarlyView.
This study uses in situ synchrotron X‐ray diffraction at the German Electron Synchrotron to analyze low‐pressure carburizing (LPC) in steels. The findings reveal surface carbon saturation and carbide formation kinetics, and phase‐specific stress development during quenching. The results show carbide kinetics depend on steel grade and size, while stress

Microstructure Evolution in Directionally Solidified Fe–C–Mn–(Si) Peritectic Steels

steel research international, EarlyView.
This study investigates how growth velocity and silicon additions affect dendritic morphology, primary arm spacing, and mushy‐zone evolution in directionally solidified quaternary peritectic steels. Silicon substantially broadens the freezing range and lengthens the mushy zone, increasing susceptibility to interdendritic cracking.

Recent advances of non‐invasive sensors for smart wearable respiratory monitoring

VIEW, EarlyView.
Respiration contains rich physiological and pathological information, making it one of the most fundamental and continuous vital signs. Respiration monitoring is a non‐invasive and simple, but incredibly powerful, tool for assessing health, managing disease, and tracking fitness.

Fluorinated CuO/ZnO/MgO Catalyst Systems for the Direct CO2 Hydrogenation to DME

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Direct CO2 conversion to dimethyl ether (DME) is a promising CO2 valorization route requiring a bifunctional catalyst for CO2 hydrogenation and MeOH dehydration. The established CuO/ZnO/ZrO2 (CZZ) system shows good activity but high material costs. Hence, a novel fluorinated CuO/ZnO/MgO (CZMg‐F) system was tested in the direct DME synthesis, offering a
