Assessment of fit accuracy and retentive strength of additively manufactured zirconia crowns luted to Ti‐base abutments with different resin cements: An in vitro study

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study investigated the influence of cement gap size on the marginal and internal fit, and cement gap size and type on retention of additively manufactured zirconia (AM‐Z) crowns on titanium bases (Ti‐base). Materials and Methods A total of 135 zirconia crowns were designed with three different cement gap sizes: 20 µm, 30 µm, and ...

Restoring soil and tree nutrition through non‐industrial wood ash additions to sugarbushes

Restoration Ecology, EarlyView.
Nutrient losses from forest soils caused by decades of acid deposition have affected tree growth and depleted soils of essential nutrients in eastern North America. Non‐industrial wood ash (NIWA) is rich in macronutrients and may be a potential remediation strategy to restore lost nutrients as a forest soil amendment.

Injectable and In Situ Hydration‐Reinforced Hybrid Bone Cements for Accelerated Bone Regeneration

Advanced Science, Volume 13, Issue 7, 3 February 2026.
To enable minimally invasive bone defect repair, an injectable and hydration‐reinforced bone cement (L‐PEGS/CPC) is designed through biomimetic reconstruction. The hydrophilic L‐PEGS organic phase provides abundant nucleation sites, synergizing with its porous architecture to accelerate CPC hydration, thereby endowing the composite with exceptional ...

Soil Organic Matter Stabilization by Polyvalent Cations in a Buried Alkaline Soil

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 2, February 2026.
Abstract Buried paleosols can store large quantities of organic carbon (C), much of which persists for millennia due to isolation from surface processes that promote decomposition. Subsoil organic matter (SOM) persistence is often enhanced by mineral associations and ionic conditions—particularly high clay content and polyvalent cations—that limit ...

From farm to field: testing different biocrust cultivation approaches and application techniques in the Sonoran Desert

Restoration Ecology, Volume 34, Issue 2, February 2026.
Abstract Drylands are among the most degraded ecosystems globally and are difficult to restore due to limited water availability. Biocrusts are a key component of maintaining soil stability and function in these systems. Since biocrust salvage opportunities are limited, cultivating salvaged biocrusts is a promising method.

Bioactive glass-ceramic scaffolds from novel 'inorganic gel casting' and sinter-crystallization [PDF]

, 2017
Highly porous wollastonite-diopside glass-ceramics have been successfully obtained by a new gel-casting technique. The gelation of an aqueous slurry of glass powders was not achieved according to the polymerization of an organic monomer, but as the ...
