What can spectroscopic techniques, such as portable X-ray fluorescence spectrometry (PXRF), reveal about the sarsen megaliths of Stonehenge and where they originated? David Nash, a professor of physical geography at the University of Brighton in Brighton, United Kingdom, is exploring this question. We recently spoke with Professor Nash about his team’s discovery and what it means for the future of archaeology.

Salvatore La Cavera III and his colleagues in the Faculty of Engineering at the University of Nottingham, in Nottingham, United Kingdom have developed a novel measurement system consisting of two ultrafast lasers that excite and detect high-frequency ultrasound from a nano-transducer fabricated onto the tip of a single-mode optical fiber.

Computerized system validation (CSV) has an uninspiring reputation for
being a slow, no-value-added activity that only wastes time and delays the
implementation of new software. Is that an accurate portrayal? And is it a
An increasing number of antibiotic residue problems in food have emerged
around the world. We examine how SERS is used to identify antibiotic residues in chicken, focusing on doxycycline hydrochloride and tylosin.
This year’s molecular spectroscopy award recipient is Bhavya Sharma, who is demonstrating research leadership focused on neurochemical detection using SERS and SORS Raman spectroscopy.
Here, we finish a discussion of the spectrum of polyethylene (PE) and explore
how different PE syntheses produce materials with different physical and
To better understand Raman spectral profiles, we briefly examine spectral line shapes, while discussing spectral shape, bandwidth, and broadening as percentage of Gaussian and Lorentzian components.
Uwe Karst of the University of Münster in Germany explains the use of laser ablation–inductively coupled plasma–mass spectrometry (LA-ICP-MS) imaging to provide spatially resolved quantification of trace elements in biological samples.

Seaweed has become a popular ingredient in Western diets. Concerns for heavy metals and inorganic arsenic have been raised as potential risks to consumers. Methods for analysis are described, including microwave digestion, HPLC,
and ICP-MS for quantitation and speciation.
The determination of metals in hygienic face masks is important for global heath
at this time. Following the guidelines of ISO 18562-4, an ICP-OES method is described including sample preparation, analysis, and validation of the methodology.
