Submerged atomic resolution imaging of calcium carbonate crystal surface

05.09.2011
Research scientists at Tohoku University achieved atomic-level observation of the crystal growth process

Hard tissues of organisms, such as bones and shells, are composed of inorganic minerals (biominerals). While these substances are created by biomineralization, which will be discussed later, many uncertainties remain in the mechanism.

Research scientists at Tohoku University have been conducting studies designed to elucidate the crystal growth mechanisms of shells, in which a calcium carbonate crystal, which is normally stable only in a high-pressure phase, is formed under normal temperature and pressure conditions.

It is necessary to observe the atomic structural changes of the growing crystal surface in solution. Under such circumstances, a system capable of high-resolution surface observation in a liquid environment would be ideal.

Tsukamoto and Araki learned that the atomic force microscope (AFM) probe system developed by the Yamada group at Kyoto University could operate under such conditions and was available for use via the Kyoto Advanced Nanotechnology Network; an application was made for joint utilization and support.

By using the FM-AFM system, based on leading-edge frequency-modulation atomic force microscope (FM-AFM) technology, they successfully observed the calcium carbonate crystal growth process in solution on the atomic level.

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...

Im Focus: Optoelectronic Inline Measurement – Accurate to the Nanometer

Germany counts high-precision manufacturing processes among its advantages as a location. It’s not just the aerospace and automotive industries that require almost waste-free, high-precision manufacturing to provide an efficient way of testing the shape and orientation tolerances of products. Since current inline measurement technology not yet provides the required accuracy, the Fraunhofer Institute for Laser Technology ILT is collaborating with four renowned industry partners in the INSPIRE project to develop inline sensors with a new accuracy class. Funded by the German Federal Ministry of Education and Research (BMBF), the project is scheduled to run until the end of 2019.
