Appraisal of Six Natural Mica Reference Materials for In Situ Rb‐Sr Geochronology

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points Evaluated six natural mica reference materials for in situ LA‐ICP‐MS/MS Rb‐Sr geochronology using geochemical, microstructural and isotopic characterisation. Identified robust primary reference materials: Mount Dromedary biotite (99.37 Ma) and Mica‐Fe biotite (307.75 Ma). La Posta biotite and Högsbo muscovite are suitable secondary reference

Clinical Performance of Bioglass‐Enriched Resin Modified Glass Ionomer in Sealing Moderate Carious Lesions: An 18‐Month Split‐Mouth Clinical Trial

open access: yesInternational Journal of Dental Hygiene, EarlyView.
ABSTRACT Dental materials with the potential for caries progression prevention have been an attractive alternative to minimally invasive treatments. Objectives This randomized controlled split‐mouth clinical trial aimed to assess, after 18 months, the retention, restoration quality, and caries progression or arrestment of active moderate carious ...

Cellular Dynamics and Dentine Bridge Formation Following Direct Pulp Capping With MTA and Biodentine in a Murine Model

open access: yesInternational Endodontic Journal, EarlyView.
ABSTRACT Aim Formation of a mineralized dentine bridge is the hallmark of successful direct pulp capping (DPC). Mineral trioxide aggregate (MTA) and Biodentine are widely used capping materials, but in vivo evidence comparing their regenerative potential remains inconclusive. This study used a controlled murine model to compare dentine bridge formation

Metamorphic or Igneous Zircon? Classification Through Rare Earth Elements, Machine Learning and Logistic Regression

open access: yesJournal of Metamorphic Geology, EarlyView.
ABSTRACT Zircon is a common, highly refractory accessory mineral found in sedimentary, igneous and metamorphic rocks that forms through various processes (e.g., magmatic, hydrothermal, metamorphic growth and recrystallization). Trace element compositions of detrital zircon have been widely applied to understanding tectonic processes and continental ...

When biology meets materials science – Interdisciplinary applications of electron microscopy

open access: yesJournal of Microscopy, EarlyView.
Abstract Research at the interface between biology and materials science creates challenges for electron microscopists. Everything from the sample preparation to the choice of imaging and analytical techniques and the interpretation of the resulting data refuses to sit comfortably within the domain of one discipline or the other.

The consequences of partial clonality on the spatiotemporal genetic structure of the red alga Chondria tumulosa (Ceramiales, Rhodophyta)

open access: yesJournal of Phycology, EarlyView.
Abstract The relative rates of sexual versus clonal reproduction partition genetic diversity, but the quantification of these rates remains limited in natural populations. This knowledge gap is particularly acute among tropical macroalgae. Chondria tumulosa is a red macroalga that has been documented at high abundance in the three northernmost atolls ...
