Surfing through the coating system of historic bowed instruments: a spectroscopic perspective

Giacomo Fiocco, Claudia Invernizzi, Tommaso Rovetta, Michela Albano, Marco Malagodi, Patrizia Davit, Monica Gulmini

Cultural heritage is a growing application area for spectroscopy, and our second article describes how infrared and X-ray spectroscopy are being used to explore the coatings used by the old Cremonese makers that produced such outstanding sound.

FAIR enough?

Robert M. Hanson, Damien Jeannerat, Mark Archibald, Ian Bruno, Stuart Chalk, Antony N. Davies, Robert J. Lancashire, Jeffrey Lang, Henry S. Rzepa

The Tony Davies Column offers a challenge to us all with another contribution on FAIR data, which should be Findable, Available, Interoperable and Readable. It is clearly the way we should all be going, everybody from manufacturers and software developers, through researchers to publishers needs to work together.

Weights or measures for better calibration

Antony N. Davies, Henk-Jan van Manen

In quantitative analysis, is it better to weigh materials when making up standard solutions or to use volumetric techniques? Traditionally, the answer has been “volume”, however, things may not be as straightforward as they seem. Henk-Jan and colleagues have conducted a new experiment, using robots for both sample preparation and spectroscopic analysis which may provide a definitive answer. Unfortunately, the answer must wait for publication of their paper, but Tony and Henk-Jan’s history of this question makes interesting reading nevertheless.

Identification of dental materials in food

Johannes Hesper

FT-IR spectroscopy and ED-XRF are used to determine the origin of contaminants in food that may, or may not, have originated from dental materials.

COVID-19: Lock-down and up-skill

Antony N. Davies, Henk-Jan van Manen

With a significant proportion of our regular readership probably under home lock-down, we were wondering if we could help you at this difficult time by pointing out some useful online resources. So, when we finally come out of this pandemic, you could do so better skilled and more up-to-date than when we went in to it.

Planning for EuroAnalysis 2021

Antony N. Davies, Lutgarde Buydens

Tony and Lutgarde Buydens give us an update on the planning for the major EuroAnalysis 2021 conference, which is being held in Nijmegen, the Netherlands, at the end of August 2021. At this stage, they are keen to gather suggestions from readers on topics they would like to see covered. Groups are also invited to consider hosting their own event under the EuroAnalysis 2021 banner.

Near infrared spectroscopy unlocks the secrets of mammalian diving success

J. Chris McKnight

This article reports on work using NIR spectroscopy to investigate the physiology of seals during diving. As well as the versatility of NIR spectroscopy, the technical achievements involved in placing a spectrometer on a seal without harming it and recording data underwater are amazing.

Application of Theory of Sampling principles for real-time monitoring of pharmaceutical powder blends by near infrared spectroscopy

Rodolfo J. Romañach, Rafael Méndez, Kim H. Esbensen

This column shows how well the Theory of Sampling is able to address the powder sampling difficulties that have plagued the pharmaceutical industry for a long time. Definitely, a practical example of the importance of representative sampling.

Determination of soil organic matter using visible-near infrared spectroscopy and machine learning

Felipe Bachion de Santana, Sandro Keiichi Otani, André Marcelo de Souza, Ronei Jesus Poppi

The authors describe work they are doing to develop a green methodology to determine soil organic matter. If the World’s population is to be fed in the future, improvements to agricultural productivity are required and soil fertility will be key to this. Current methodologies are time-consuming and expensive, but visible-near infrared spectroscopy has the potential to replace them.

Old burned bones tell us about past cultures

G. Festa, C. Andreani, M. Baldoni, V. Cipollari, C. Martínez-Labarga, F. Martini, O. Rickards, M.F. Rolfo, L. Sarti, N. Volante, R. Senesi, F.R. Stasolla, S.F. Parker, A.R. Vassalo, A.P. Mamede, L.A.E. Batista de Carvalho, M.P.M. Marques

Burned bones are often found in archaeological sites as a result of fire or funerary practices and are often the only preserved human remains. Using inelastic neutron scattering, infrared and micro-Raman spectroscopies, the authors can reach definitive conclusions as to the temperature at which the bone was burned. This enables archaeologists and anthropologists to learn more about how ancient civilisations used fire for funerary, burial or cooking purposes.

Near infrared spectroscopy, the skeleton key for bone identification

Aoife C. Power, James Chapman, Daniel Cozzolino

Knowledge of the origin of bones has applications in anthropology, archaeology and forensics; NIR spectroscopy, even with handheld instruments, is showing promise in being able to differentiate bones from different species.

Infrared spectroscopy and chemometrics to evaluate paper variability in document dating

Carolina S. Silva, Maria Fernanda Pimentel, José Manuel Amigo, Carmen Garcia-Ruizc, Fernando Ortega-Ojedac

Spectroscopy is widely used in forensics, but the determination of the age of documents was one application I had not considered. With a huge variety of papers and inks available, each with their own ageing profiles, and with such ageing depending on environmental factors, the determination of the age of a document is not straightforward. However, infrared spectroscopy and chemometrics may have the answer.
