Comparison of surface treatment protocols for a 3D‐printable resin for definitive crowns: Effects on surface roughness and bonding performance

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose This study aimed to compare the effects of surface treatment protocols on the surface roughness and shear bond strength (SBS) of a three‐dimensional (3D)‐printable resin for definitive crowns. Materials and Methods A 3D‐printable resin for definitive crowns (Saremco Print Crowntec) was used to produce 168 specimens (10 × 10 × 2 mm3 ...

Chromic Oxide as an Indicator of Total Fecal Output in White-tailed Deer

open access: yes, 1977
Two captive rumen-fistulated white-tailed deer (Odocoileus virginianus) were used to evaluate chromic oxide as an external indicator of total fecal output.

Au(I) Complex With an Abnormal Carbene Ligand Shows Anti‐Kasha Dual Photoluminescence Emission

open access: yesAngewandte Chemie, Volume 138, Issue 38, 14 September 2026.
Incorporation of an abnormal N‐heterocyclic carbene into a heteroleptic linear Au(I) complex induces anti‐Kasha dual emission responsive to biologically relevant phenyl sulfate. ABSTRACT We report the first photoactive linear Au(I) complex with an abnormal N‐heterocyclic carbene (aNHC) ligand, Au(aIm)(Cz).

Revisiting olivine‐phyric shergottites: Pyroxene crystallization pressure and the role of undercooling

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Shergottites are the most abundant meteorites from Mars and a major source of information on magma reservoirs, transport, and eruption, particularly in the late Hesperian northern hemisphere. Conflicting interpretations have arisen on the crystallization conditions of pyroxene in olivine‐phyric shergottites.

Rhizosphere Engineering by Root Exudates: High‐Yielding Alfalfa Recruits Functional PGPR to Sustain Soil Nutrient Availability Under Long‐Term Cultivation

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Soil nutrient transformation capacity is a critical determinant of sustainable productivity in perennial cropping systems; however, the extent to which high‐yielding crops actively regulate rhizosphere microbial assembly to maintain nutrient availability remains poorly understood.

Understanding exosomes in regenerative dentistry

open access: yesPeriodontology 2000, EarlyView.
Abstract Background Regenerative dentistry is shifting from cell‐based strategies to cell‐free biologics capable of orchestrating intricate tissue repair. Exosomes, nanosized extracellular vesicles carrying bioactive molecular payloads, have emerged as central modulators of intercellular communication.

A note on the use of chromic oxide incorporated in a feed to estimate faecal output in ruminants

open access: yes, 1967
Chromic oxide (Cr2O3) has been used for some time as an inert marker to estimate the faecal output of livestock. Although several methods of administration have been reported (Grassland Research Institute, 1961) the more widely used form would appear to ...
