Emerging nuclear methods for historical painting authentication: AMS-14C dating, MeV-SIMS and O-PTIR imaging, global IBA, differential-PIXE and full-field PIXE mapping

There is a considerable interest in developing new analytical tools to fight the illicit trafficking of heritage goods and particularly of easel paintings, whose high market values attract an ever-increasing volume of criminal activities. The …

The Potentialities of Accelerator-Based Techniques as an analytical Tool for Forensics: the case of Coffee

In this work we discuss how different accelerator-based techniques can be employed synergistically in order to provide a powerful analytical tool for forensic studies of foodstuff. To that end, a Brazilian coffee was chosen as a showcase due to its …

Broad Range FTIR Spectroscopy and Multivariate Statistics for High Energetic Materials Discrimination

The objective of this work was to measure infrared spectra of high explosive materials (HE) in wide spectral range in order to acquire information for their complete characterization and find out the regions that are the most discriminatory for each …

Development of continuous CNT fibre-reinforced PMMA filaments for additive manufacturing: A case study by AFM-IR nanoscale imaging

High performance carbon nanotube fibres and yarns with similar strength to Kevlar could now offer significant structural reinforcement and multifunctionality to 3D printed parts. However, recently printed parts which were reinforced with …

Fano resonance in asymmetric plasmonic nanostructure: Separation of Sub-10 nm Enantiomers

Separating enantiomers is vital in chemical syntheses, life sciences, and physics. However, the usual chemical processes are inefficient. Recently, plasmonic nanostructures have drawn considerable attention for manipulating nanoparticles; however, …

Tunable Mid‐Infrared Phase‐Change Metasurface

The intense light–matter interaction of plasmonic metasurfaces provides an appealing platform for optical sensing. To date, most metasurface sensors are not spectrally tuned. Moreover, they operate in a total reflection mode, which complicates the …

Revealing Chemical Heterogeneity of CNT Fiber Nanocomposites via Nanoscale Chemical Imaging

Lightweight nanocomposites reinforced with carbon nanotube (CNT) assemblies raise the prospects for a range of high-tech engineering applications. However, a correlation between their heterogeneous chemical structure and spatial organization of …
