From Damage to Functionality: Remanufacturing of Thrust Roller Bearings by Tailored Forming

Advanced Engineering Materials, Volume 27, Issue 16, August 2025.
Herein, the wear and fatigue behavior of repaired bearing raceways with a new powder alloy is investigated using a FE8 test‐rig and an oscillating tribometer. The tests are compared with industrial manufactured bearings to evaluate the repair quality. The repair can extend the service life of the repaired bearing to that of a new bearing and improves ...

Occupationally Relevant Zinc‐ and Copper‐Containing Metal Fumes Inhibit Human THP‐1 Macrophage TNF and IL‐6 Responses to Bacterial Stimuli

Global Challenges, Volume 9, Issue 5, May 2025.
Metal workers have an increased risk of severe pneumonia due to metal fume exposure. In this study, zinc oxide (ZnO) and copper oxide (CuO) particles are found to inhibit specific anti‐bacterial macrophage responses, which may substantially contribute to impaired lung immunity.

Comparative Fatigue Analysis of Structural Steels Considering Welding and Surface Effects

Strain, Volume 61, Issue 2, April 2025.
ABSTRACT There are limited data on the very high‐cycle fatigue for structural steel welds for over 10 million cycles. The purpose of this research is a fatigue performance comparison of the welds made of steels S355JR+AR and S275JR+AR. The goal of reaching the gigacycle fatigue domain is achieved using the ultrasonic fatigue testing at 20 kHz.

Instability Mechanism in Thermoelectric Mg2(Si,Sn) and the Role of Mg Diffusion at Room Temperature

Small Science, Volume 5, Issue 3, March 2025.
This work investigates a multistep material degradation mechanism driven by Mg diffusion within n‐type Mg2(Si,Sn) thermoelectrics while stored under ambient atmosphere at room temperature. It involves Mg bulk diffusion as a limiting process step for Mg migration toward the sample surface and subsequent reaction with moisture leading to a pronounced ...
