The Next Generation-Interview with Luca Flamigni

We are starting a new section in JAAS News in which we will try to find out the views of the younger generation of atomic spectroscopists. Today, we are publishing an interview with Luca Flamigni, who is currently a PhD student in Detlef Gunther’s group at ETH Zürich (Switzerland).

Luca Flamigni in his lab at ETH Zürich

Who or what inspired you to become a scientist?

I have always been interested in technical and scientific aspects of life and nature. I think I inherited this curiosity from my father, who is a biologist and teaches science and mathematics in a secondary school.

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

After my MSc in chemistry at ETH, I decided to pursue a PhD in analytical chemistry. At that point, I had done three projects in analytical chemistry at ETH and I was convinced that mass spectrometry was appealing the most to me. After being accepted as a student by Prof. Günther, I had no more doubts that analytical chemistry was my field of interest and joined his group for micro and trace analysis. ETH has a great infrastructure, is a world-class university, and is not too far from my home town.

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

My work is dedicated to a better understanding of the processes occurring inside the inductively coupled plasma (ICP) for mass spectrometric analysis of laser-produced aerosols. The theoretical considerations and experimental results obtained during my thesis will lead to new quantification strategies and instrumental developments on the ICP side.

How is a typical day in your lab?

I have two different typical days, depending on whether I am doing measurements or working at the computer. When I work in the lab, I usually try to get everything up and running until lunch, which is very early – at around eleven – in our group. Then, in the afternoon, I first run the most important experiments, which are on my schedule. If there is time left, I continue with what I thought of during the first experiments. If I am working in the office, I usually do repetitive, bureaucratic and easier tasks in the morning, when I tend to be less creative, then I do all the programming and interpretation in the afternoon.

What common activities are organized in your research group?

Our group is known for its good social life. For every accepted manuscript, the first author invites all group members for a drink after work. A few times every semester we meet for a barbecue or a drink for special occasions and when we have visitors. Other than that, every two years there is a group retreat, where we gather somewhere for two or three days. Last time we went to a castle close to the Lake Constance in the North-East of Switzerland. It was really a picturesque place to visit.

What app/programs do you typically use?

Everybody here in the lab knows me as an ImageJ enthusiast. ImageJ is a free piece of software used for image processing and microscopy. I do most of my work with it and have a folder full of useful macros to perform many tasks, such as size determination of micro-droplets, evaluation of SEM pictures, particle tracking etc. Beside the typical programs (Microsoft Office, Origin, SigmaPlot, LabVIEW, Adobe Photoshop), I am sometimes programming in Java using the NetBeans IDE and I recently started to experiment with Comsol for the simulation of flow systems.

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

I read at least twice a week the “recent articles” pages of JAAS and of the other analytical chemistry journals. When I find something interesting, I add the bibliographic information to Zotero, which is a browser plugin. When I do bibliographic research for a paper, I use SciFinder, which is a very powerful tool provided by the ETH library. I also use Google Scholar, which is helpful to retrieve information from outside the field of analytical chemistry. When I write a paper, I import the bibliography I have in Zotero into EndNote, which integrates well with Microsoft Word.

Which type of articles do you prefer?

We are forced to read broader, but clearly I like the articles on ICP-MS. Many of them are dealing with laser ablation and I find them always very interesting. Recently, I started to pay more attention also to the LIBS articles. LIBS is having a sort of revival, and it is a technique, which is related to LA-ICP-MS, even though sampling and plasma are not separated. This feature is the reason for both its advantages (simplicity, cost) and its disadvantages (quantification capabilities, robustness) in comparison with LA-ICP-MS. I like how both techniques are advancing over time and I think that they both have a lot of potential.

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

I especially like that I can both spend time in the lab and at the computer. This makes the work much more interesting and less repetitive. I also enjoy the freedom I have in planning and designing the experiments and see myself as lucky, because I can directly access so many tools and services at ETH, from the mechanical workshop to the chemical warehouse. What I do not like so much here in Zurich is the weather, which is quite dark and gray all year long. In addition, this is sometimes reflected on the mood of people, who tend to be gloomy.

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

This is a very tough question. I hope that I will be doing something related to analytical chemistry, or at least science and technology in general. I am very open to new challenges, but I believe that I have learnt a lot about what is achievable nowadays with modern instrumentation and I would like to exploit this knowledge. I actually have a personal interest in forensics and criminology, which I may try to cultivate professionally.

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

Contrarily to most Swiss people, I am not a very sporty person. I like to play tennis from time to time and to ski during the winter, but my principal hobbies are actually indoors. I play the piano – mostly jazz and blues – and I enjoy composing music on my computer. I have a digital piano, a synthesizer and I am a proud owner of a keytar, which is a keyboard that one can hold like a guitar. I also like digital photography and electronics, and to relax I like to watch movies and to play computer games.

Thanks a lot for your detailed answers, Luca!

Mars: Where the Sky is Orange

Sirven et al. featured on the front cover of JAAS, 2007, Issue 12

Yesterday the Royal Society of Chemistry had the pleasure to meet the driver of the Mars Curiosity rover Paolo Bellutta who revealed the secrets of Mars one year after the first ‘landing’ in 2012.

You might remember the paper published in 2007 in JAAS about ChemCam, the powerful instrument now functional part of the Mars Science Laboratory Curiosity rover used to study the red planet.

ChemCam uses laser induced breakdown spectroscopy (LIBS) to remotely analyse the surface of Mars looking into the chemistry of its rocks.

Jean-Baptiste Servien and colleagues at CEA Saclay, France, introduced the three chemometric approaches used by ChemCam to study the rocks on the surface of Mars in the paper entitled Feasibility study of rock identification at the surface of Marsby remote laser-induced breakdown spectroscopy and three chemometric methods.

Mars Curiosity rover on the red planet

Last August, Curiosity successfully landed at Gale Crater on the planet Mars. Paolo Bellutta, Rover’s driver from NASA’s Jet Propulsion Laboratory, explained what is behind a one-ton vehicle that is able to land in such a hostile place where the wind runs at 400Km/h, the temperature reaches -90°C and the sky turns orange.

How do we drive on Mars? And what are we doing on Mars ? To know everything about the Mars Mission watch the video soon available on The Reaction website.

Reconstructing how the Romans made glass

Man has been making glass since the third millennium BC and during the manufacture of ancient glass, antimony, in a metal or mineral form, was added to make it colourless or opaque.

Different antimony ores have slightly different antimony isotope ratios and researchers in Belgium and the UK have developed an inductively-coupled plasma mass spectrometry (ICP-MS) method to detect and quantify these tiny differences. By analysing samples of Roman glass, the team hope to uncover clues about how the glass was made and the geographical provenance of the raw materials.

Broad bobbin collar too fashionable?

While X-ray fluorescence (XRF) spectroscopy is a well-established technique for the investigation of paintings, the apparatus used are usually custom built and not widely available. Now, Matthias Alfeld and colleagues have developed a portable macro XRF spectrometer to look at paintings in situ.

The team used the device to look at a portrait by Govert Flinck, a Dutch painter who was a protégé of the great Rembrandt. Interestingly, they found that originally the subject was painted wearing a broad bobbin lace collar and long lace cuffs but this was toned down for the final version, possibly because it was too trendy.

2015 European Winter Conference on Plasma Spectrochemistry

Those of you who attended the Closing Ceremony of the recent 2013 Winter Conference on Plasma Spectrochemistry in Krakow, will have heard that the RSC was planning to host the 2015 European Winter Conference in Glasgow, with Professor Joerg Feldmann from University of Aberdeen as Chair.

You may also have seen that nominations to host the conference in 2015 are now open again, and you could be wondering why this is.

We are sad to say that our submitted bid was not felt to be suitable by the Continuation Committee, and so we have respectfully acknowledged their decision. However we would like to take this opportunity to assure you that we did not withdraw our support, and that it has always been our intention to act in support of the community and in accordance with your wishes.

We became involved in the bidding process because after the Zaragoza conference, we were approached by members of the community who asked if the RSC would be willing to consider supporting a bid to bring the conference back to the UK after 20 years. Following careful consideration of the Conference Constitution, we consulted with the Chair of the Krakow conference to ask whether our involvement as a society would be possible. No concerns were raised with us that were not addressed in our bid and in discussions with the Committee, prior to the awarding of the bid to Glasgow.

After this initial agreement made in Krakow, the Committee still had serious concerns regarding aspects of the bid, including the level of the involvement of the RSC, such that they do not believe it to be in the best interest of the community for us bring the Winter Conference back to the UK in 2015.

The RSC has a long history of involvement with the atomic spectrometry community and the Winter Conferences.  Our intention with the Glasgow bid was and will continue to be, to support the community in whatever way we can. It goes without saying that we look forward to working with and supporting you in the future.
