DNA extracted from boiled archival fish bones yields high‐quality whole‐genome sequencing data

open access: yesJournal of Fish Biology, EarlyView.
Abstract Archival samples provide a unique source of organismal DNA, offering the potential to extend the temporal scale of genetic studies by decades to centuries. Fish hard structures, such as otoliths and scales, serve as records for fish collected during fisheries monitoring across a large spatiotemporal scale.

Phase content of metal-matrix composites of the system Fe-W-C which are formed by plasma precipitation

open access: yesВестник Донского государственного технического университета, 2018
Melt crystallization peculiarities of the system have been investigated by means of X-Ray diffraction and microstructure analysis. It is shown that content changing of hexagonal tungsten carbide in the mixture essentially influences processes of phases ...

Bond strength and interfacial analysis of six CoCr alloys made by conventional casting and selective laser melting

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To investigate the effects of the elemental composition and the manufacturing process of cobalt chromium–molybdenum (CoCr–Mo), cobalt chromium–tungsten (CoCr–W), and CoCr–Mo‐W alloys on metal–ceramic bond strength. Materials and Methods Six CoCr‐based alloys were included in this study, a were classified into three different groups ...

Effect of adhesives and mechanical surface treatments on the hard relining of CAD‐CAM denture bases

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose The aim of this study was to evaluate the impact of mechanical roughening, adhesive applications, and aging on the bonding between CAD‐CAM denture base materials with distinct chemical contents and hard relining material. Materials and Methods A total of 300 denture base specimens were produced by additive, subtractive, and ...

A Dual Cell‐Line Molecular Platform to Assess Sub‐Threshold Biocompatibility: Application to Processed Orthodontic Clears Aligners

open access: yesOrthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objective Traditional biocompatibility assessments primarily address cytotoxicity and bulk material properties but often overlook molecular responses that occur below toxicity thresholds. Detecting these subtle effects is crucial for materials intended for prolonged contact with human tissues.

The oral microbiota and periodontal health in orthodontic patients

open access: yesPeriodontology 2000, EarlyView.
Abstract The oral microbiota develops within the first 2 years of childhood and becomes distinct from the parents by 4 years‐of‐age. The oral microbiota plays an important role in the overall health/symbiosis of the individual. Deviations from the state of symbiosis leads to dysbiosis and an increased risk of pathogenicity.

Progressively Fenitised Schist and Carbonatitic Clasts From a Metasomatic Aureole Beneath the Alkalic Dunedin Volcano, Otago, New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Clasts of albite‐porphyroblastic quartzofeldspathic schist, derived from the Otago Schist basement, occur within the Port Chalmers Breccia, a diatreme at the centre of the Dunedin stratovolcano, New Zealand. Schists have undergone varying degrees of replacement reactions (at temperatures of 300° to >500°C) producing hornfelses, with Ca‐ and K‐enriched ...

Accelerated Fatigue Testing of High‐Speed Steel

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 6, Page 2156-2166, June 2026.
ABSTRACT The staircase method is commonly employed in the characterization of metals to determine their fatigue limit. In this approach, the stress amplitude is systematically varied around the assumed fatigue limit in consecutive tests. However, its applicability for in‐process optimization in alloy design and development is limited by the large ...

Preparation and mechanical properties of refractory metal carbide reinforced tungsten‒rhenium alloys

open access: yesFenmo yejin jishu
Metal carbide doped tungsten‒rhenium alloys were prepared by the traditional pressureless sintering method. The effects of ZrC, TiC, and HfC metal carbides on the microstructures and mechanical properties of tungsten‒rhenium alloys were studied, and the ...
