Who or what inspired you to become a scientist?

At school I was always interested in Sciences. During high school, I decided to study Chemistry, after having read some articles about the role of a chemist in society.

Why did you choose your research group/University and what factors influenced your choice?

During my graduation, at Universidade Federal de Santa Maria, I was given the chance to work with different analytical techniques. At the end of my degree I decided to work with Atomic Absorption Spectrometry (AAS), which led me to do my TCC, which is a first supervised research work to conclude the graduation course, at the Laboratory of Trace Analysis at Universidade Federal do Rio Grande do Sul (UFRGS), coordinated by Prof. Maria Goreti R. Vale. This TCC work increased my interest in this technique even more; consequently I decided to take my Master and Doctorate in this area. Considering the fact that the Laboratory of Trace Analysis offers an adequate infrastructure for the development of my research, and that UFRGS is one of the best universities of Brazil, I chose to follow my studies there under the supervision and orientation Prof. Maria Goreti. During my PhD work I also had the opportunity to spend one year at the Institute of Analytical Chemistry of the Academy of Science of the Czech Republic in Prague under the supervision of Dr. Jiři Dědina in the frame of a sandwich program. This gave me the opportunity to work with other techniques, to know new people and a different culture, which contributed very much to increase my horizon, scientifically and personally.

Can you explain a bit the purpose of your current research activities?

My current research is based on the application of the AAS technique for the development of analytical methods. I am currently working on the development of analytical methods for the quantification of non-metals using High-resolution Continuum Source Graphite Furnace Molecular Absorption Spectrometry (HR-CS GF MAS). Besides this project, I have been developing another study related to the leaching of metals and metalloids from different food containers, particularly from pewter cups produced in Brazil.

How is a typical day in your lab?

I am not able to stay for a long time in the laboratory to make measurements, due to my recent activities as a Professor. Having to divide my time among giving classes, research and doing the paperwork, what I usually do is to plan the experiments and discuss the results with the students in the lab early in the morning and at the end of the afternoon when I finish my classes.

What common activities are organized in your research group?

Eventually we gather to make a barbecue or a happy hour to celebrate birthdays, presentation of final papers or the approval of a scientific project.

How do you search for scientific information? How do you manage your bibliography?

To make the bibliographic review I make use of the Web of Science. In addition, I usually access the websites of the main Journals in the field, to follow what is being published, and I save in folders, ordered by subject, those articles that I find relevant.

What are your views on JAAS? Which type of articles do you prefer? Do you miss some content?

JAAS is one of the most important Journals in the field of Atomic Spectrometry, being a reference for me since the beginning of my graduation. Nowadays, I wish there were more articles about sample preparation, as well as method development and applications involving AAS techniques, mainly using high-resolution continuum source AAS and high resolution continuum source molecular absorption spectrometry.

What do you like and dislike the most about your work?

I really like my work and I feel honored for being able to provide classes and carry out research activities simultaneously. I am happy with what I do. I do not really like the administrative paperwork, which is automatically inserted in my duties. Having to administrate money for my research and face bureaucracy and delay for the purchase of material/reagents is really annoying.

What do you expect to be doing in 5 years time?

I have recently reached a position, which I have aimed for a long time: the one of being a Professor at UFRGS. In five years time I hope to have acquired the potential to widen the structure of the Laboratory of Trace Analysis and to be satisfied with the research developed during this time. Besides that, I hope to contribute to the formation of graduate and post-graduate students.

What do you enjoy doing when you are not in the lab?

I really like going out with my friends or going to a park on the weekends. I also like reading a lot of books of general literature.

Thanks for sharing your views with us, Morgana, and congratulations on your recent position!

1st Workshop on Biomedical Applications of Geochemistry

We are pleased to announce the first Workshop on Biomedical Applications of Geochemistry that will be held at Gargonza, Tuscany (http://www.gargonza.it/index.html) after the Florence Goldschmidt conference from the 30th Aug (evening) to the 1st Sept (afternoon).

Gargonza, Italy, 30th Aug-1st Sept.

You can register for the workshop here.

This workshop will be the opportunity to present new results on the growing field of the use of natural stable isotope fractionation in biomedicine, both for understanding homeostasis in normal and pathological conditions and as potential new biomarkers. This will be also the chance for scientists coming from isotopic mass spectrometry (IRMS and MC-ICPMS) and from biomedicine to meet for setting up an authentic interdisciplinary community devoted to the development of stable isotopes in health sciences.

Committed speakers for this event are Francis Albarède (ENS Lyon), Ariel Anbar (Arizona State University), Anton Eisenhauer (Geomar), Frank Vanhaecke (Ghent University), Thomas Walczyk (National University of Singapore).

For any information about the workshop, please write to Vincent.Balter@ens-lyon.fr.

We are also pleased to announce that the works presented at Gargonza will be invited to submit to Journal of Analytical Atomic Spectrometry and Metallomics for a themed web collection of papers.

JAAS Issue 6 is out now!

A great new issue of JAAS is now available online! Take a look at our brilliant covers and enjoy the latest research in the field of atomic spectrometry in cultural heritage and geology analyses.

Our beautiful outside front cover shows the front facade of the Cathedral of Malaga, one of the best architectural features of the region of Andalusia in Spain. Researchers at the University of Malaga analysed the materials composing the main facade and the pollutants present on the surface by laser-induced breakdown spectroscopy (LIBS). Using this technique, they were able to thoroughly characterise the sandstones, marbles and metals composing the most highlighted section of the main facade and identified the most relevant pollutants that are damaging the appearance of this historical building.

Analysing historical artifacts in a non-destructive manner

Isotope determination by portable laser ablation sampling

A portable laser ablation sampling device can help analyse valuable historical artifacts.

The study is shown in a paper just published in JAAS by Advisory Board member Detlef Günther and colleagues at the Swiss Federal Institute of Technology, ETH, Zürich, Switzerland.

The researchers used laser ablation coupled to a multicollector inductively coupled plasma mass spectrometry (LA-ICPMS) to determine lead isotopes in Chinese ceramics, and applied a portable device to enable remote analysis. Laser generated aerosol samples were collected on membrane filters and consequently analysed in the laboratory by LA-ICPMS. With the new device, sampling of objects is independent of their location, size and shape.

This new method showed an analytical performance similar to a laboratory-based analysis and enabled simultaneous isotopic and elemental analysis without invasive sampling such as scraping or drilling of the objects.

To know more about this study, please access the link below. This paper will be free to read until May 24th.
