Small, EarlyView.Thermo‐responsive granular hydrogels (TRGHs), composed of microparticles and an interstitial matrix, exhibit thermo‐responsive mechanical properties and allow cell infiltration. This system effectively addresses the conventional compromise between mechanical strength and porosity observed in granular hydrogels.

steel research international, EarlyView.High Nb (2.4 wt.%) addition to Maraging 300 steel drives lattice distortion and nanoscale Nb–Mo‐rich precipitation, confirmed by energy‐dispersive X‐ray spectroscopy mapping (Mo ~5.4 wt.%, Nb ~2.5 wt.%). Nanoindentation reveals strong matrix hardening (H >4.8 GPa) at 480°C aging, while 560°C induces ~1.92 vol.% reverted austenite, enabling tunable ...

Damage Investigation of the Preform Operations for the Production of Rings for Ring Rolling
steel research international, EarlyView.Void evolution during the preforming operations of two industrial ring rolling process routes is investigated by combining metallographic characterization with a two‐scale finite element simulation approach. The results reveal that, despite differing initial void conditions, the preforming operations can be designed to effectively influence void ...

Mineworkers' Perspectives on Whole‐Body Vibration Exposures in the Ghanaian Mining Industry
Safety Science and Technology, EarlyView.ABSTRACT Across most industries, there appears to be greater commitment to occupational safety than to occupational health, largely because safety effects are readily observable, whereas health effects are hard to notice, as they take prolonged exposure to become apparent.
