IBAME Science Award

PD Dr. Catherine McCammon received the Science Award given by the International Board on the Applications of the Mössbauer Effect (IBAME) “in recognition of her outstanding contributions to geophysically relevant questions via novel methodological approaches using the Mössbauer effect”.

The award was presented at the International Conference on the Applications of the Mössbauer Effect (ICAME) 2017 held in St. Petersburg, Russia.

Publication in Nature Communications

A new study led by CarboPaT members reported in Nature Communications that iron carbonate forms new structures that make it stable at high pressures and temperatures. They found that carbon and oxygen form a tetrahedral arrangement, and iron becomes more oxidised. Their work demonstrates that these new structures can carry carbon into the deep part of the Earth through oxidation-reduction reactions that can influence the cycling of volatiles including carbon and oxygen.

Sponsorship of the 3rd DCO Early Career Scientist Workshop

CarboPaT is one of the official sponsors of the Third Deep Carbon Observatory Early Career Scientist Workshop. This five-day workshop was initiated by the Deep Carbon Observatory (DCO) in collaboration with Sapienza University. Taking place in Nicolosi, Sicily, the workshop will include several fieldtrips to Mt. Etna. In addition, there will be keynote presentations as well as talks and posters by the participants and many roundtable discussions.

The DCO Early Career Scientist Workshops were conceived to bring together young researchers for building networks and initiating new collaborations. Around fifty early career researchers will attend the workshop this year. Through the sponsorship of the CarboPaT research unit, two PhD students from CarboPaT will receive financial support to attend the workshop.

The success of the Early Career Scientist Workshops is already tangible. CarboPaT member Dr. Valerio Cerantola attended the First DCO Early Career Scientist Workshop in Costa Rica in 2014 when he was a PhD student. He developed such an enthusiasm and support for the concept that he is now part of the organising committee of the upcoming workshop.

Gregori Aminoff Prize

The Gregori Aminoff Prize in Crystallography has been awarded to Prof. Dr. Natalia Dubrovinskaia and Prof. Dr. Leonid Dubrovinsky, both principal investigators within the FOR 2125. They developed new experimental methods to investigate crystal structures in situ under extreme conditions (high pressures and high temperatures) that are present in the Earth's interior.

The ceremony took place during the anniversary celebration of the Royal Swedish Academy of Sciences in the Konserthuset in Stockholm on the 31st of March. HM Carl XVI Gustaf the King of Sweden handed the prizes over to the laureates.
