Growth Behavior of Monohydrocalcite (CaCO3·H2O) in Silica-Rich Alkaline Solution

Growth Behavior of Monohydrocalcite (CaCO3·H2O) in Silica-Rich Alkaline Solution

Zhang, G.; Delgado-López, J. M.; Choquesillo-Lazarte, D.; García-Ruiz, J. M., Crystal Growth & Design 2015, 15 (2), 564-572. Download paper. Monohydrocalcite (CaCO3·H2O) has been crystallized in silica-rich alkaline water solution. The crystallization proceeds by a counterdiffusion method without the presence of any other additive except dissolved silica. The crystallization has been followed in situ by optical microscopy and Raman microspectroscopy, while the time evolution of the pH and the concentration of calcium and silica species…

Sobre los Experimentos de Creación de Vida de Andrew Crosse

Garcia-Ruiz, J. M., Macla 2015, 20, 61-62. Uno de los personajes más exitosos y conocidos de la historia de la literatura y el cine de ficción es el creado por la escritora Mary Shelley en 1817 en su libro “Frankenstein o el moderno Prometeo”. Paradójicamente, uno de los científicos menos conocidos y más misteriosos de la historia de la ciencia británica es Andrew Crosse, el individuo real en el que, según se suele afirmar, Mary…

Teaching High School students at Limuru

Teaching High School students at Limuru

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…

Prometheus at the Science Week

Prometheus at the Science Week

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…

Field trip to Malaga

Field trip to Malaga

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,…
