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

Journal 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 sintering cycle on the strength and translucency of multilayered zirconia

Journal of Prosthodontics, EarlyView.
Abstract Purpose A newly introduced sintering protocol promises to offer higher translucency while not significantly compromising the flexural strength of the material. However, the effect of the novel sintering protocol has not been thoroughly validated.

Pressed lithium disilicate glass ceramics: Microstructural characterization, in vitro and in silico nonlinear dynamic analysis for biaxial flexural strength

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the mechanical properties of lithium disilicates, and to assess the predictive capability of in silico models for biaxial flexural strength (BFS). Materials and Methods Specimens of four heat‐pressed lithium disilicates (IPS e.max Press, Rosetta SP, LiSi Press, Vintage Prime Press) were obtained.

Deformation of δ‐AlOOH and Its Solid Solution With Phase H as a Potential Source of Intra‐Slab Seismic Anisotropy in the Mid‐Mantle

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Seismic anisotropy is widely observed near subduction zones in the mantle transition zone and uppermost lower mantle, particularly along the western Pacific rim and tracks slabs geometries, implying an additional slab‐related source. Hydrous phases such as δ‐AlOOH and phase H (MgSiO4H2), which form a solid solution (δ‐H) and are stable in cool,

Siderite Concretions in Svalbard Lake Sediments Capture 7,000 Years of Extreme Arctic Cold Season Climate Change

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract The Arctic warms faster than anywhere else on Earth, and paleoclimate data are key to placing this amplified response in a long‐term context. But most past temperature proxies record growing season conditions, when their biological signal carriers are produced.
