Quantitative micro‐XRF combined with X‐ray imaging reveals correlations between Zn concentration and dentin tubule porosity across entire teeth

VIEW, EarlyView.
The combination of calibrated micro‐CT and quantitative micro‐XRF measurement facilitates the correlation of density and composition in the 3D macro‐structure of teeth. Zn concentration in dentin increases by a factor of 10 toward the pulp. Incidentally, the overall density decreases, showing an association between Zn and the dentin tissue porosity ...

Surface Micro‐Discharge Plasma for Multiple Teeth Bleaching: Efficacy, Mechanism and Safety

High Voltage, EarlyView.
ABSTRACT Hydrogen peroxide (H2O2) is the commonly‐used bleaching chemical in clinical practice, but its excessive concentrations can cause tooth damage. Atmospheric pressure cold plasma is considered a promising new technique for tooth bleaching. Surface micro‐discharge (SMD) devices can generate large‐scale plasma, which holds potential for treating ...

A reappraisal of the Middle to Later Stone Age prehistory of Morocco Réévaluer la préhistoire du Maroc, du Middle Stone Age au Later Stone Age

Journal of the Royal Anthropological Institute, EarlyView.
Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.

Exploring marking methods for the predatory hoverfly Sphaerophoria rueppellii (Diptera: Syrphidae)

Insect Science, EarlyView.
As important pollinators and predators of aphids, hoverflies play an important role in ecosystems. This study focuses on identifying the best marking technique for the model species Sphaerophoria rueppellii that can be used to track hoverfly feeding and oviposition sites, evaluating three methods: rubidium (RbCl), fluorescein, and fluorescent dusts ...
