M. Montalti, G. Zhang, D. Genovese, J. Morales, M. Kellermeier & J.M. García-Ruiz, Nat Commun. 2017 Feb 16;8:14427. Download paper. Bottom-up self-assembly of simple molecular compounds is a prime pathway to complex materials with interesting structures and functions. Coupled reaction systems are known to spontaneously produce highly ordered patterns, so far observed in soft matter. Here we show that similar phenomena can occur during silica-carbonate crystallization, the emerging order being preserved. The resulting materials, called…

Teaching High School students at Limuru

Posted on March 13, 2017March 14, 2017 by prometheus

During the first trip to the Rift Valley of the Prometheus Project, I asked my Kenyan contact Patricia Gitari to seek for the possibility to organize an event to transfer high school teachers in Kenya my experience in popularization and teaching of crystallography. She did a great work, and she organized in Limuru, a town near Nairobi, an exceptional event. She was able to attract more than 150 students and teachers from different schools of…

Field trip to Dallol

Posted on January 25, 2017April 20, 2020 by prometheus

The field trips to Dallol have been successfully performed in January 2016 and January 2017. We have collected samples of liquid, gases, air and air particles, etc… and make numerous in-situ measurements of physical and chemical variables such as pH, temperature, pressure, salinity, conductivity, oxygen, redox, visible spectra, etc… The aim of this project is to perform: A rigorous study of the hydrochemistry of the brines including the analysis of the organic compounds and gases. …

Prometheus at the Science Week

Posted on January 25, 2017September 16, 2019 by prometheus

Science is essential for the evolution of the humanity. This is the reason why science community should encourage kids, teenagers and adults to explore the magic world of science. The Week of Science (November 7-12, 2016) is an event that offers the opportunity to get a closer look at the work that scientists do. We invited the students of several schools of Granada to join our journeys inside giant crystal caves in Mexico, camp in…

LEC goes back to Space!

Posted on January 25, 2017September 16, 2019 by prometheus

Prof. Garcia-Ruiz organized the 1st ‘International Training School on Crystallography for Space Sciences’, supported by the COSPAR, the IUCr, the INAOE and the BUAP with the participation of scientists from UNAM, NASA, ESA, the University of Groningen, the Laüe-Langevin Institute, the UVa-CSIC, the Hokkaido University, the IPGP, the Tohoku University and the McMaster University. For 17 days the 30 MSc-/PhD-students and Post-Doc researchers that attended the School received intensive courses about Crystal Growth, Symmetry and…

Field trip to Malaga

Posted on January 25, 2017April 24, 2020 by prometheus

On the 27-29th September of 2015 we carried out our first field work in the nearby alkaline springs in the Ronda peridotites of the Betics (Province of Malaga, SW Spain). The goal of the field trip was to observe the geological features of the area, and explore the different serpentinization-related alkaline spring sites. We visited numerous alkaline springs in the wider area of the peridotites, and we conducted preliminary on site measurements of water temperature,…
