Tailoring Microstructure and Hardness in Maraging 300 Steel via 2.4 wt.% Niobium Addition and Controlled Aging Treatments

open access: yessteel 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 ...

Hypercortisolism: Causes, Consequences and Clinical Significance – A Review of Pathophysiology

open access: yesDiabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Hypercortisolism or Cushing syndrome is a heterogeneous clinical spectrum caused by chronic glucocorticoid excess, ranging from exogenous Cushing syndrome to rare endogenous aetiologies and the increasingly recognised entity of mild autonomous cortisol secretion (MACS). Physiological cortisol production is tightly regulated by the hypothalamic–

Effectiveness of self‐etching ceramic primer on the bond strength of dental glass ceramics: A systematic review and meta‐analysis of in vitro studies on feldspathic and leucite‐reinforced ceramics

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose This systematic review and meta‐analysis evaluated the bond strength effectiveness of a self‐etching ceramic primer, specifically Monobond Etch & Prime (MEP), compared to hydrofluoric acid with silane (HF+S) in feldspathic and leucite‐reinforced dental glass‐ceramics (DGCs). Materials and Methods This study followed PRISMA‐p guidelines
