A Multi‐Analytical Approach for the Compositional Characterization and Chronological Discrimination of Benin (Nigeria) Metal Sculptures

open access: yesArchaeometry, EarlyView.
ABSTRACT This study presents a multi‐analytical archaeometric approach for the compositional characterization and chronological discrimination of Benin metal sculptures in relation to the 1897 Punitive Expedition. The methodology integrates elemental composition (XRF and ICP), stable lead isotope ratios (MC‐ICP‐MS) for alloy system characterization ...

Dentifrices for preventing erosive tooth wear: An in vitro comparative study

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract Erosive tooth wear is a progressive condition that compromises enamel structure and requires preventive strategies. This in vitro study aimed to compare the protective effects of fluoride‐based dentifrices containing various bioactive agents on sound enamel subjected to simulated erosive–abrasive challenges.

Computational Investigation on the Combined Effect of Applied Strain and Pore Configuration on Strain Concentrators in Additively Manufactured Metals

open access: yesFatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Metal additive manufacturing (AM) provides a pathway for creating highly optimized components that would be difficult to produce using traditional manufacturing methods. However, regardless of printing parameters or postprocessing, porosity remains a prevalent challenge in AM components because strain concentrates in the vicinity of the pore ...

Investigation of Creep Properties of Ti‐43Al‐5V‐4Nb Alloy Considering Oxidation Effects Using Miniature Specimens

open access: yesFatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT In the present study, creep tests of a TiAl alloy were conducted using miniature specimens (d = 2 mm) under various conditions to investigate their creep properties at 760°C. The test results indicate that creep rupture time obtained using miniature specimens at identical applied stress levels increase with the order of test condition Ar gas ...

Influence of Finish Line and CAM Unit on the Marginal Adaptation and Margin Trueness of Lithium Disilicate Glass‐Ceramic and Composite Resin Onlay Restorations

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the marginal adaptation and margin trueness of lithium disilicate glass‐ceramic (LDS) and glass‐filler reinforced composite resin (CR) onlays fabricated using three different finish lines and two chairside CAM units (4‐ and 5‐axis). Methods LDS (e.max CAD) and CR (Tetric CAD) onlays were fabricated on butt joint, chamfer,
