All CO2 React fellows will spend time on secondment at another institute within the consortium. Following their placements, the fellows will update this page with information about their stays at the secondary host institution.

Ana Hernandez: ESR West Systems Italy -> Lafarge, France

A short secondment was held at Lafarge research and Innovation center from 15th-26th June, 2015 in Lyon. The main work performaned during this period was work on cement hydration and carbonation processes using Reaction Path Modelling. This allowed us to study cement corrosion and main solid phases produced during both processes. We have submitted one abstract to the University of Berkeley together. I plan to return to Lafarge this winter or at the beginning of next year. While in France, I also visited the CNRS labs in Toulouse and attended the PhD day where some fellows from the CO2 REACT project, as well as other Marie Curie ITNs gave oral presentations. I was very impressed with Lafarge-I was made to feel very welcome, everything was very well organized, and the people I worked with were very kind and hardworking ....So, I'm looking forward to going back there.

Fulvio di Lorenzo: ESR Uni Oviedo -> Uni Münster

I spent three months in Münster working with Christine V. Putnis on coupled dissolution-recrystallization processes at nanoscale by Atomic Force Microscope. My work was focused on processes involving formation of carbonate minerals for those metals (Ca, Fe, Mg) abundant in basaltic rocks; these rocks constitute the target of CO2 injections (for the CarbFix project) aimed at in situ mineralization of carbon dioxide as carbonate.

AFM experiments were performed in fluid cell passing slightly supersaturated solution on freshly cleaved mineral surfaces. Different solutions, mineral surfaces and techniques were used with the aim to study features and properties of different solid solutions among carbonate minerals. The great number of experiments and data collected during this period will be a strong departure point for further publications after that results will be confirmed with more experiments with different techniques.

Together with experimental work, this secondment experience was really important to improve my scientific knowledge and background because I often attended weekly seminars at Institut für Mineralogie; also, it was important to develop my human skills to move to a different laboratory in another country. I really want to say thanks to the great scientists involved in the CO2-react project for giving me the opportunity to have these wonderful experiences that I had in Münster and not only in Oviedo.

Alvaro Sainz Garcia: ESR Amphos 21 -> CNRS Toulouse

I did my secondment in Toulouse at the GET Laboratory of the CNRS. A national research center is a refreshing environment with many PhD students from CO2-React and other ITN's but also from many other sources of funding and nationalities. With the guidance of the students and Dr. Oelkers, I spent some time in the laboratory and got familiar with tools and practices far from my world of loops and RAM memories in modelling. I also attended Grand Seminars given by experts in different fields of earth science. During my stay I worked on a paper on the interaction between convective mixing and geochemistry that hopefully will be the first publication of my PhD.

Beatriz Vallina: ESR Uni Leeds -> Uni Copenhagen

I did my secondment in Copenhagen at the Nano-Science center. This center belongs to the Chemistry Department and is headed by Prof. Susan Stipp. My work in Copenhagen was focused on data analysis and interpretation from experiments about rare-earth elements and boron carried out at University of Leeds. For doing this work I have counted on the collaboration of Dr Juan Diego Rodriguez-Blanco (Assistant Professor at the University of Copenhagen). During my stay, I also wrote the manuscript entitled "The role of amorphous precursors in the crystallization of La and Nd carbonates". Thanks to the collaboration between both universities (University of Leeds and University of Copenhagen) the manuscript was published in Nanoscale (a high impact international journal).

Christian Grimm ESR CNRS Toulouse -> Uni Iceland and Uni Leeds

I spent my secondment at the Earth Science Institute of the University of Iceland in Reykjavik (one month) as well as in at the School of Earth and Environment of the University of Leeds (one week). My local supervisors were Sigurdur R. Gislason and Liane G. Benning, respectively.

In Iceland I organized a sampling cruise at the south coast of the Reykjanes Peninsular to evaluate the correlation between particulate suspended matter and primary productivity in the coastal zone. Before, during and after the sampling I got extraordinarily great support especially from Eydis Eiriksdottir, Becca Neely and Deirdre Clark at the University of Iceland. Furthermore, I´d like to greatly acknowledge the Grindavik Coast Guard and the Marine Research Institute in Reykjavik for their cooperativeness. During this secondment I could not only produce scientific data but also gain a lot of experience in autonomously organizing a sampling trip.

Two months later, I went for one week to the University of Leeds in England to use the environmental Scanning electron Microscope (SEM). I´ve been analyzing samples I took during the sampling trip in Iceland as well as samples from various lab experiments. This resulted in excellent images of microbes interacting with minerals. Again the help of the team during and prior to my visit was really great and it was another successful trip and valuable experience.

Reza Gooya ESR Uni Copenhagen -> Amphos 21

I spent two months at the company AMPHOS21 in Barcelona, Spain. AMPHOS21 is an international environmental consultancy that offers consulting services in 5 main sectors including CCS and climate changes. The objective of my stay was to couple a flow solver based on Lattice Boltzmann method with the chemistry solver PHREEQC in our pore scale system. The ability to predict the system at pore scale can provide a source of knowledge for detailed understanding of geological phenomena. The CO2-water-rock interaction at pore scale is fundamental to quantify changes in porosity-permeability in reservoirs selected for CO2 geological storage. Prediction of such behavior can be provided by reactive transport calculations that I developed during my stay.
