Posidonia oceanica Leaves as a Natural Filler for Poly(Butylene Succinate‐Co‐Adipate) Composites: Characterization and Biodegradation Assessment in Seawater

Journal of Vinyl and Additive Technology, EarlyView.
This study shows that incorporating 5–10 wt.% Posidonia oceanica, with or without micro‐talc, in PBSA preserves thermal stability, modifying crystallization behavior, and maintains good filler dispersion and interfacial adhesion. Mechanical properties are moderately stiffened.

Automated particle analysis of D.B. Cooper's tie

Journal of Forensic Sciences, EarlyView.
Abstract Automated particle analysis (APA) using scanning electron microscopy (SEM) and energy‐dispersive x‐ray spectrometry (EDS) is a well‐known method in forensics, especially as it is applied to gunshot residue analysis. Here we describe the analysis of particles lifted from D.B. Cooper's tie, which was left on the hijacked plane in 1971.

Effect of Endodontic Sealers on the Bond Strength of Glass Fibre Posts: A Systematic Review

Australian Endodontic Journal, EarlyView.
ABSTRACT This systematic review evaluated the influence of resin‐based, eugenol‐based and bioceramic endodontic sealers on the bond strength of glass fibre posts cemented with resin cements. Searches were conducted in PubMed, Scopus, Web of Science, Cochrane Library, Google Scholar and Embase, including in vitro studies using human or bovine teeth ...

Enterococcus faecalis and Endodontic Treatment Failure: A Qualitative Systematic Review of Its Role and Elimination Strategies

Australian Endodontic Journal, EarlyView.
ABSTRACT The aim of this study was to synthesize evidence on the influence of Enterococcus faecalis on endodontic treatment failure and strategies for its elimination. This study followed the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines and was registered in PROSPERO (CRD420251022741).

Knowledge and Perceptions of Preformed Metal Crowns and Pulpotomies in Primary Molars Amongst Dental Students in Amsterdam, the Netherlands—A Questionnaire‐Based Cross‐Sectional Study

European Journal of Dental Education, EarlyView.
ABSTRACT Introduction Preformed metal crowns (PMCs) and pulpotomies are established treatments for carious lesions in primary molars. Despite their effectiveness, variability in knowledge and clinical experience amongst dental students has been reported. This study aimed to evaluate the knowledge and perceptions of Dutch dental students at the Academic

Development of CCMb: A Low‐Mg Calcite Reference Material for In Situ Measurement of δ18O, δ13C and Selected Trace Elements

Geostandards and Geoanalytical Research, EarlyView.
Key Points Low‐Mg calcite RM developed for in situ microanalysis applications in palaeoclimatology (δ18O, δ13C; Mg, Sr m/m). New data for calcite CRM IAEA‐603 (δ18O, δ13C by SIMS and GS‐IRMS; Mg m/m). No detectable IMF effect of Mg on SIMS δ18O determinations for mass fractions < 3650 μg g‐1.
