Europium‐ and dysprosium‐modified strontium aluminate: A luminescent marker system for enhanced gunshot residue detection

open access: yesJournal of Forensic Sciences, EarlyView.
Abstract Forensic ballistics is essential in analyzing evidence from firearm use in criminal investigations, with gunshot residue (GSR) detection providing key information about the firearm and shooting conditions. Traditional methods like spectroscopy and scanning electron microscopy (SEM) have limitations in sensitivity, cost, and accessibility ...

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

open access: yesJournal 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.

Droughts and human impact in the ancient Uaymil region of the Maya lowlands inferred from a 2800‐year sedimentary archive at Lake Kaná, Mexico

open access: yesBoreas, EarlyView.
The relationship between the climate and societal transformation in Maya lowlands has long been debated, particularly the role of drought in shaping the civilization trajectory during the Classic Period. A high‐resolution, multi‐proxy, geochemical record from Lake Kaná, located in the underexplored Uaymil region of the Yucatán Peninsula in Mexico ...

Development of a Nano‐Hybrid Composite Using Bovine Hydroxyapatite and Montmorillonite for Endodontic Applications—An In Vitro Study

open access: yesInternational Endodontic Journal, EarlyView.
ABSTRACT Aim Hydraulic calcium silicate cements are widely employed in endodontics due to their excellent biocompatibility, bioactivity, sealing ability, and remineralisation potential. However, currently used products such as mineral trioxide aggregate (MTA) exhibit several limitations, including discolouration, cost, and poor handling properties ...
