Fracture load and three‐dimensional internal void analysis of direct composites used to restore worn molars

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract This study evaluated (1) the load‐bearing capacity of molars restored with direct occlusal veneers fabricated either from short‐fiber‐reinforced composite (SFRC) or particulate‐filled composite (PFC) and the presence of internal voids within the materials, and (2) effect of water storage on the fracture load and correlation between internal ...

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 ...

Nanoscale space weathering features in mature lunar soil revealed by TEM and APT

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Space weathering significantly alters the optical, chemical, and structural properties of lunar regolith at micro‐ and nanoscales; yet detailed nanoscale variability within individual soils remains underexplored. Here we apply transmission electron microscopy (TEM) and atom probe tomography to four mineral grains (olivine, ilmenite, and two ...

The Impact of Digital Technologies on Skills‐to‐Job Mismatches

open access: yesNew Technology, Work and Employment, EarlyView.
ABSTRACT A pervasive discourse calls for worker upskilling amid ongoing digital transformation. This study introduces a skills‐to‐job mismatch perspective into research on the digital transformation of work by conceptualising technological adoption as a process that reshapes the relationship between workers’ skill endowments and evolving job ...

Black mangrove growth and root architecture in recycled glass sand: testing a new substrate for coastal restoration

open access: yesRestoration Ecology, EarlyView.
As coastal regions experience accelerating land loss, artificial substrates may be useful in restoration efforts to replenish sediment and facilitate plant colonization. Recycled glass sand is a potential artificial substrate for marsh building due to its sustainability, availability, and similarity to natural substrates.

Advances in Floating Solar Desalination Systems

open access: yesWater and Environment Journal, EarlyView.
This review critically classifies floating solar desalination systems into five main categories and compares their thermal performance, productivity and technological limitations. Membrane‐based and multieffect systems showed the highest efficiencies, while traditional designs remain limited by heat losses and scaling.
