Experimental and numerical investigation on the flexural response of GFRP‐reinforced SFRC beams

Structural Concrete, EarlyView.
Abstract In order to address the challenges related to the deformability and ductility of concrete beams reinforced with fiber reinforced polymer (FRP) bars, an alternative solution involving steel fiber reinforced concrete (SFRC) has been proposed. In the present study, a total of seven beams—including one steel‐reinforced reference beam and six glass

Geopolymers as a Sustainable Chemical Platform: From Building Materials to Advanced Functional Applications

The Chemical Record, EarlyView.
Geopolymers are presented as a chemically programmable platform whose properties emerge from activation chemistry, nanoscale disorder, and interfacial design. The review highlights sustainability challenges, the shift toward nanoengineered and hybrid systems, and the rise of halloysite‐based architectures enabling tunable structures across scales for ...

Time‐resolved synchrotron X‐ray total scattering of alkali‐activated materials with high and low calcium contents

Journal of Synchrotron Radiation, EarlyView.
Synchrotron in situ high‐energy X‐ray total scattering/pair distribution function (PDF) analysis quantifies the time‐resolved structural evolution of high and low calcium alkali‐activated binders, with PDF peak evolution tracking reaction progress and correlating with calorimetry (R2 > 0.97).

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.

Mortars From Punic and Hellenistic–Roman Solunto: Materials, Formulations, and Technology

Archaeometry, EarlyView.
ABSTRACT This study presents an archaeometric investigation of 18 hydraulic rendering and bedding mortars from Punic and Hellenistic–Roman Solunto (NW Sicily). The research aimed to characterize raw materials, reconstruct manufacturing sequences, and evaluate technological proficiency through mineralogical and petrochemical analyses.

Antifouling capacity of substrate materials and their effects on settlement and post‐settlement survival of Acropora palmata and Orbicella faveolata

Restoration Ecology, EarlyView.
Abstract Introduction In coral reef restoration, sexual reproduction is a key methodology to enhance coral population recovery. However, post‐settlement survival remains a major bottleneck, as spat are particularly vulnerable to competition with fouling organisms.
