Increasing the Reuse Potential of High‐Strength Steels by Extending the Fatigue Life through Surface Treatments

open access: yessteel research international, EarlyView.
Surface reconditioning through mechanical and electrochemical polishing is shown to extend the fatigue life of predamaged 42CrMo4 steel by over 12 times. By removing ≈100 μm of surface material, surface‐driven fatigue damage is mitigated. This study introduces a reuse potential metric to evaluate fatigue recovery and support sustainable steel reuse.

Fluid Field and Temperature Field Analysis of High Speed Magnetic Field Modulated Gears

open access: yesJixie chuandong, 2023
When a high speed magnetic field modulated gear is working, eddy current loss and wind friction loss will occur in permanent magnet and magnet block. In order to study the flow field and temperature field in small gaps of high speed magnetic gears, a ...

Mobile electromagnetic levitator for time‐resolved in situ X‐ray diffraction studies of high‐temperature phase transformations

open access: yesJournal of Synchrotron Radiation, EarlyView.
A mobile electromagnetic levitator combined with time‐resolved synchrotron X‐ray diffraction enables in situ studies of high‐temperature phase transformations without container‐induced contamination and reveals the first direct observation of metastable phase formation in undercooled Fe–Co alloys.In situ observations of high‐temperature transformations,

Comparison of a Miniaturized Implantable Two‐Stage Rotodynamic Blood Pump to Equivalent Single‐Stage Concepts

open access: yesArtificial Organs, EarlyView.
This study aims to evaluate the potential of a multistage pump design to enhance hemocompatibility in left ventricular assist devices. We found that the two‐stage concept offers favorable hemolysis measures compared to single‐stage designs, as the reduction in peak shear stresses outweighs the disadvantage associated with prolonged residence time ...

Non‐Rigid 3D Shape Correspondences: From Foundations to Open Challenges and Opportunities

open access: yesComputer Graphics Forum, EarlyView.
Abstract Estimating correspondences between deformed shape instances is a long‐standing problem in computer graphics; numerous applications, from texture transfer to statistical modelling, rely on recovering an accurate correspondence map. Many methods have thus been proposed to tackle this challenging problem from varying perspectives, depending on ...

Points vs. passes: A comparison between electric fishing techniques for sampling fish populations in upland headwater streams

open access: yesJournal of Fish Biology, EarlyView.
Abstract Point‐abundance sampling by electric fishing (PASE) was compared with single‐pass (DF1) and triple‐pass depletion sampling (DF3) electric fishing on the same reaches of four headwater streams sampled over multiple years in the Ribble catchment, UK. Juvenile salmonids, mostly brown trout Salmo trutta with some Atlantic salmon S.
