Thermal and mechanical properties of Mg–Al–Si–O–N glasses with up to 6.2 at.% nitrogen
Abstract This study investigates the structural, thermal, and mechanical properties of Mg–Al–Si–O–N glasses. Six compositions with increasing nitrogen content from 1.7 to 6.2 at.% were synthesized by melting mixtures of high‐purity oxide and nitride precursors, followed by quenching and annealing.

Pressure‐induced quenchable superhard tetrahedral amorphous phase of BC4N
• A quenchable tetrahedral amorphous phase with a high fraction of sp3 bonding is observed. • The tetrahedral phase exhibits ultra‐high incompressibility and a high Vickers hardness, classifying it as a superhard material. • The material demonstrates semiconducting behavior with a narrow bandgap.

ABSTRACT Objectives This study aimed to quantify polymerization shrinkage, microhardness, and depth of cure of different types of bulk‐fill composites. Methods Six bulk‐fill composites were tested: SonicFill 2 (SCF), VisCalor (VVC), Admira Fusion x‐tra (AFX), Filtek Bulk Fill (FBF), Fill‐Up! (FUP) and GrandioSO Heavy Flow (GHF).
