Journal of Applied Toxicology, EarlyView.ABSTRACT Toxicological assessment is essential in NP approval for health and medical applications. Although 2D cell culture has been widely used, 3D models, especially spheroids, provide better predictive value for toxicological risk assessments since they replicate complex cellular interactions more accurately.

Exploring Suicide Prevention Gatekeeper Interventions for Schools: A Scoping Review
Psychology in the Schools, EarlyView.ABSTRACT Background Among teenagers and young adults, suicide represents a significant public health challenge. Schools are critical for suicide prevention due to the significant time adolescents spend there. Gatekeeper training (GKT) has shown promise in increasing awareness and knowledge, but its implementation‑relevant characteristics and contextual

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 ...
