Corrosion in Modular Revision Hip Stem Tapers – A Retrieval Analysis

Journal of Orthopaedic Research, Volume 44, Issue 2, February 2026.
ABSTRACT In revision hip arthroplasty, modular stems enable intraoperative adjustment of the biomechanics of the hip to ensure a stable joint function even in complex anatomical cases. Modular stem junctions, however, carry the risk of junction degradation due to corrosive processes or even junction breakage.

Enhancing Efficiency in Double‐Pipe Heat Exchangers: A Detailed Review of NanoFluids and Their Impact on Thermal Performance

Heat Transfer, Volume 55, Issue 1, Page 212-240, January 2026.
ABSTRACT This study reviews recent advances in using nanofluids to enhance double‐pipe heat exchanger (DPHE) efficiency. The review examines several types of nanofluids, that is, water‐based graphene oxide and CuO–water nanofluids, assessing their effectiveness under different operating conditions, including inlet temperature and nanoparticle volume ...

Evolution of a laser shock peened residual stress field locally with foreign object damage and subsequent fatigue crack growth [PDF]

, 2015
Foreign object damage (FOD) can seriously shorten the fatigue lives of components. On the other hand, laser shock peening improves fatigue life by introducing deep compressive residual stress into components.

Fatigue Limit Doubling in High‐Strength Martensitic Steel through Crack Embryo Engineering–Cyclic‐Training‐Driven Self‐Optimization

Advanced Science, Volume 12, Issue 33, September 4, 2025.
This study demonstrates a breakthrough in overcoming the conventional fatigue limit ceiling in high‐strength as‐quenched martensitic steel; maximum stress corresponding to the fatigue limit significantly increased from 675 to 1300 MPa with minimal sacrifice in tensile strength (1.5–1.6 GPa).

Microscale Metal Additive Manufacturing by Solid‐State Impact Bonding of Shaped Thin Films

Small, Volume 21, Issue 36, September 11, 2025.
The deposition of device‐grade metals is one key challenge toward additive micromanufacturing. The impact‐induced solid‐state bonding of metal thin films for the additive assembly of high‐purity, high‐density metals with micrometer‐scale precision, is introduced.
