A common mineral found in super-deep diamonds has been named after the Frankfurt mineralogist and petrologist

Important mineral named after Professor Gerhard Brey 

FRANKFURT. Diamonds are messengers from Earth's interior. A portion of the rare gem, which is very small but important for researchers, contains inclusions from the earth's lower mantle. One of the most common minerals brought to the Earth's surface in this way has now been named “breyite" by the Commission of the “International Mineralogical Association" in honour of the mineralogist Professor Gerhard Brey from Goethe University.

The interior of the Earth is largely inaccessible for sample recovery. Intensive drilling efforts can reach a maximum depth of 12 kilometres, which represents a mere scratching on the surface. Volcanoes, on the other hand, can transport samples from significantly deeper zones to the Earth's surface. The samples that come from the greatest depths are inclusions of minerals and rock fragments in valuable diamonds. These inclusions were one of the fields of research of Gerhard Brey, meanwhile retired Professor for Petrology and Geochemistry at the Institute for Geosciences at Goethe University. 

According to prevalent theories, Earth's lower mantle (at a depth of 660 – 2900 kilometres) consists almost exclusively of the three minerals silicate perovskite, ferropericlase, and a mineral rich in calcium and silicon with a perovskite structure. When diamonds form at this depth, it can happen that they trap this mineral. During transport to the earth's surface, the calcium-silicon perovskite converts to a new crystal structure that is stable at lower pressure. This mineral is only known as inclusion in diamonds. It now bears the name breyite. 

“Having a mineral named after you is a very special honour and pays tribute to the life work of a scientist in a special and lasting way," states Brey's colleague, the geoscientist Professor Frank Brenker. “Especially when we're talking about such an important Earth mineral. 

Gerhard Brey's name is now forever carved in stone, so to speak." Gerhard Brey, who retired in 2014, is considered a pioneer in experimental petrology under high-pressure conditions. He achieved world recognition through the development and calibration of geothermobarometers for rocks in the earth's mantle. These thermobarometers are not only crucial aids in researching the Earth's interior, they are also very popular in the search for new diamond deposits. While it used to be necessary to process tons of rocks to determine whether the deposit in question really contained diamonds, now only a few grains of mineral are necessary. 

In addition to thermobarometric calculations, Brey is interested in the solubility of fluids and gases, including their influence on the formation of magmas. Along with other colleagues, he was one of the first researchers to recognize the scientific value of inclusions in diamonds with origin depths of hundreds of kilometres. Brey has received a numerous distinctions, including an honorary doctorate from the Russian Academy of Sciences and the Abraham-Gottlob-Werner silver medal, which he was awarded by the German Mineralogical Society for his life's work.

Goethe University and partner universities want to form network as “European University“ – “Trust through mobility“ as central theme

Standing shoulder to shoulder with Milan, Lyon and Birmingham

FRANKFURT. Goethe University has joined ranks with universities in Milan, Lyon and Birmingham to form an alliance of European universities for more intensive cooperation in the future. In February they will together apply for the title “European University” and funding by the EU. On Monday and Tuesday, the partners met in Frankfurt to discuss goals and opportunities of the collaboration.

“This application for ‘European University’ is a great opportunity for Goethe University,” said Professor Rolf van Dick, Vice President of Goethe University and responsible for international affairs, speaking informally during the meeting. As European University, networking in Europe would be strengthened and scientific and non-scientific projects could be tackled.

Three to five universities can apply together for the title “European University” with the European Commission. Important requirements are a common, long-term education strategy; a common (virtual) “European Campus”; and research and a student body characterized by diversity that can place their focus on the challenges of the future. Goethe University already has a partnership with the University of Birmingham, the Université Lumière Lyon II and Sciences Po Lyon, and the Università Cattolica del Sacro Cruce in Milan, and as partner cities, all four cities are furthermore on friendly and familiar terms. As “European University”, their cooperation could be intensified and made more concrete. If successful, the consortium will receive funding amounting to € 5 million for an initial three years.

In a well-received speech in September 2017, French President Emmanuel Macron proposed the creation of 20 European universities by 2024, referring to networking and alignment between existing European universities as opposed to the creation of new institutions. In difficult times for the European Union, university science and scholarship should be strengthened as an important engine for European integration. This would enable the younger generation, in particular, to again develop a stronger connection to the project of Europe. But scientific knowledge and learning are in general of great significance for developing a European identity – as manifested in the past by examples such as the Erasmus exchange programme, and collaborative research projects funded by the EU.

Macron affirmed his ideas impressively at Goethe University in October 2017. “It really inspired all of us,” says van Dick. In April, a task force was created, headed by van Dick. “It’s exciting, actually,” said James Walker from the Université Lumière Lyon II, praising Goethe University’s initiative. “We quickly found ourselves on the same page regarding our objectives and values. It almost doesn’t matter if our application isn’t successful. We’ll cooperate anyway,” says Walker. “It’s vital for us, as universities, to work together. If we cannot cooperate, how can we expect it of our politicians?” said Michael Whitby from the University of Birmingham, alluding to the Brexit crisis. And Edilio Mazzolini from Università Cattolica in Milan is “proud to be a part of this network“, because the identity of his university is “deeply European“.

Mobility, the meeting summed up, should be a central issue of the European University. Mobility of students, of scientific and non-scientific personnel, and also the mobility of ideas. The universities face similar challenges, for example in teaching, and together they will be able find better solutions. Birmingham has been a strategic partner for years; cooperation between the faculties of law and economics has existed for several years with Université Lumière Lyon II; with Sciences Po Lyon there is a lively partnership between the political science faculties; and Goethe University has a common master’s degree in film studies with Milan.

Economist Nicola Fuchs-Schündeln awarded € 1.6 million ERC Consolidator Grant

A better understanding of labour market behaviour and success

FRANKFURT. Why do some groups behave differently in the labour market than others? What determines labour market success? And which effect do public policies have in this context? These questions are at the centre of a new research project by Frankfurt economist and Leibniz Award winner Nicola Fuchs-Schündeln. The project has been made possible by the European Research Council (ERC)’s Consolidator Grant, one of the largest awards funding scientific research in the European Union. It has just been announced that Fuchs-Schündeln, who is currently in Australia for a research sabbatical, will receive a Consolidator Grant this year. Her project is titled: “Macro- and Microeconomic Analyses of Heterogeneous Labor Market Outcomes.” 

“For the second time within a very brief period, I have the pleasure of congratulating Nicola Fuchs-Schündeln on an impressive distinction,” comments University President Birgitta Wolff. “Following the Leibniz Prize from the Deutsche Forschungsgemeinschaft (German Research Foundation), this exceptional economist has now also brought an ERC Consolidator Grant to Frankfurt, which is an enormous success. It demonstrates the great recognition Fuchs-Schündeln enjoys also in the international research community. We are happy to have a colleague like her, with her innovative research approach, among us. In her research, she combines macro- and microeconomic methods and directs her view towards unconventional and innovative questions – a great enrichment for scientific dialogue and for Goethe University.” 

Since 2009, Nicola Fuchs-Schündeln has been Professor for Macroeconomics and Development at Goethe University Frankfurt. She is a principle investigator in the Excellence Cluster “The Formation of Normative Orders”, as well as in the LOEWE Centre “Sustainable Architecture for Finance in Europe”. From 2015 to 2016, she was a Visiting Professor at Stanford University in California. Fuchs-Schündeln received her Ph.D. from Yale and worked at Harvard as an Assistant Professor of Economics before joining Goethe University. She studied Latin American studies and economics at the University of Cologne.

As in her previous work, in the ERC project “Macro- and Microeconomic Analyses of Heterogeneous Labor Market Outcomes”, Fuchs-Schündeln remains true to her research style of combining macro- and microeconomic methods. The 46 year-old economist plans to carry out four subprojects; three examine differences in labour market behaviour and success of men and women, while the fourth one is concerned with differences in hours worked between poor and rich countries. Labour market data from the Institute for Employment Research (IAB) and the Federal Statistical Office will serve as primary data sources. Individual work biographies, as well as company personnel strategies, can be gleaned from anonymized social insurance data from employees and employers.

One of the subprojects will pursue the question of how maternity leave policies affect the labour market success of women of child-bearing age, explains Fuchs-Schündeln. Although intended as not only family-friendly, but more specifically female-friendly policies, maternity leave policies may have negative consequences, because they could make employers more cautious about employing and promoting women. “These potential negative effects have not been investigated yet,” says the researcher. Such insights are not only of interest for Germany, since maternity leave policies are being discussed and implemented in many countries. Another subproject deals with the phenomenon that an increasing female share in an occupation correlates with decreasing relative wages of this occupation. “There are several hypotheses to explain this: It might be the case that an increasing female share lowers the prestige of an occupation – or the correlation might arise because women place a higher value on amenities such as flexibility, and greater flexibility comes with lower wages,” explains Fuchs-Schündeln. Along with other sources, this research will be based on data from East Germany, where women had made greater advances in technical occupations.

Fuchs-Schündeln will not carry out all this research alone. Several doctoral candidates and a postdoc will be involved in the project. “The research agenda is rather data-intensive,” states the economist. There are enough qualified candidates for these doctoral positions in Frankfurt, Fuchs-Schündeln observes. “At the faculty of economics and business administration, we have a structured doctoral program - the Graduate School of Economics, Finance, and Management, GSEFM - in which we jointly educate and train young researchers. That’s one of Goethe University’s great strengths.” The ERC project will be funded through 2024 with € 1.6 million.

The ERC Consolidator Grant is the latest in a series of honours: At the beginning of 2018, Fuchs-Schündeln won the Leibniz Award, the most prestigious German research award. In 2016, she was given the Gossen Award by the Verein für Socialpolitik (German Economic Association), the most important German award for economics. In 2010 she also already received a Starting Grant from the European Research Council.

Award winner Alexander Vogel carries out research for better air quality

Searching for the sources of particulate matter

FRANKFURT. Particulate matter is a form of pollution whose sources are not all understood to this day. The very complex mixture is formed in the atmosphere from various gaseous precursor molecules. Identifying their sources and improving air quality is the goal of Alexander Vogel, Professor for Atmospheric Environmental Analytics at Goethe University. For his research projects, he received the Adolf Messer Foundation Award at a ceremony on 26th November. In honour of its 25th anniversary, the award amounts to € 50,000 this year. 

University President Professor Birgitta Wolff: “Congratulations to Alexander Vogel! He is doing research on an issue of global importance that affects us all, especially in metropolitan areas: particulate matter. His research can contribute to a better understanding of this threatening phenomenon and make the cities of the world healthier. We thank the Foundation for its tireless work on behalf of early career researchers at Goethe University. And we welcome the fact that the Foundation has addressed its historical responsibility in its recently published clarification on the role of its namesake Adolf Messer.” 

Hessian Minister for Education, Culture and the Arts Boris Rhein: „My warmest congratulations to Professor Alexander Vogel. His research is highly relevant – particulate matter threatens our health and is something we must understand and learn to combat. Excellent research, such as that done by Professor Vogel and many of his colleagues, requires excellent conditions. Now the government of the state of Hesse and the universities in Hesse have both signed the Higher Education Pact for the years 2016 to 2020, creating financial planning certainty for Hesse’s universities through 2020. The Higher Education Pact is a milestone for Hesse as a science location and guarantees Hesse’s universities € 9 million in financial resources for the next five years. That is the largest sum ever made available to Hesse’s universities.” 

Foundation Board Chair, Stefan Messer, stressed: “Every foundation should make it their job to support projects and ideas that are not adequately covered by basic government funding. This is the idea pursued by our non-profit foundation in its funding and recognition of scientists stand out due to their exceptional achievements. We are very happy that in 2018, innovation, scientific curiosity, and pioneering spirit have been recognized for the 25th time in this manner.” 

About the award winning project

According to estimates by the World Health Organisation, about 6.5 million people worldwide die prematurely due to air pollution, most of which can be attributed to particulate air pollution. Contrary to popular opinion, most particulate matter doesn’t enter the atmosphere straight from tailpipes or power plants, but is formed in the atmosphere itself out of gaseous precursor molecules. This secondary particulate matter consists of the tiniest particles with an average diameter in the nanometre-range. These can penetrate deep into the lung and even enter the blood via the alveoles.  An example for the formation of secondary particulate matter is the oxidation of nitrogen oxides from diesel engines: the resulting nitric acid molecules react with ammonia in the atmosphere to create ammonium nitrate.

The inorganic precursor molecules and their development to secondary particulate matter have been well investigated: nitrogen oxides from traffic and industry, sulphur dioxide from coal-burning power plants and ammonia from agriculture. But there are numerous organic molecules on top of this that also occur in nature, such as the terpenes emitted by spruce forests. Organic precursor molecules emitted by human activity in relation to the formation of secondary particulate matter is a highly topical research area. These precursor molecules and their interaction with inorganic trace gases have only been rudimentarily investigated to date. The clear identification of the products of these chemical reactions is made difficult by the fact that the molecules often have the same mass, although their structures are different.

While he was a postdoctoral fellow at the Paul Scherrer Institute in Switzerland, Alexander Vogel developed a method for creating a molecular fingerprint from atmospheric particular matter samples. By analysing them, he can determine the secondary formation mechanism. The molecular fingerprint of particulate matter samples from Los Angeles, for example, exhibits a high percentage of nitrogen-containing organic molecules. “This allows the assumption that a reduction in nitrogen oxide emissions would also lead to a reduction of organic particulate air pollution in urban areas,” Vogel explains.

However, to elucidate the formation mechanisms of individual substances, further analyses of atmospheric samples and specific laboratory experiments in which the formation of particulate matter is simulated are necessary. By comparing field measurements with experiments, Alexander Vogel can already assign a portion of the signals in the real samples to certain processes and precursor molecules. Of the remaining unknowns, at least the molecular formula can be determined, so that potential sources and formation mechanisms can be investigated in further laboratory tests.

Alexander Vogel will now set up the experimental method he developed at the Paul Scherrer Institute at Goethe University. Among other things, he requires a machine for high performance liquid chromatography, which thanks to the Adolf Messer Foundation can now be acquired. His research approach has been met with great interest among environmental science master degree students. The measurements are due to begin at the start of 2019. Applications for master’s and doctoral theses are already coming in.

The great relevance of this topic will also be emphasized in a symposium accompanying the award. With the title “Understanding particulate matter: A grand challenge of the 21st century?”, particulate matter measurement at the Frankfurt International Airport, smog in Chinese cities, and the health effects of particulate matter will be discussed.

Alexander Vogel, born in 1984, studied chemistry at Johannes Gutenberg-Universität Mainz. After receiving his Ph.D. (2014), research on the CLOUD experiment took him to the European Organization for Nuclear Research CERN by Geneva and the Paul Scherrer Institute in Villigen, Switzerland. He has been a tenure-track professor for atmospheric environmental analysis at Goethe University since January 2018.
