Freeze-drying yields stable and pure amorphous calcium carbonate (ACC).

Johannes Ihli et al.

Chemical communications (Cambridge, England), 49(30), 3134-3136 (2013-03-13)

A simple synthetic method is presented for the precipitation of high purity, dry amorphous calcium carbonate (ACC) based on freeze-drying saturated, counter ion free CaCO3 solutions, where the ACC produced shows an extended atmospheric stability. Translation of the methodology to

Thermally induced phase transformation of pearl powder.

Guoqing Zhang et al.

Materials science & engineering. C, Materials for biological applications, 33(4), 2046-2049 (2013-03-19)

The polymorphic phase transformation of thermally treated pearl powder was investigated by X-ray diffraction and thermoanalytical techniques. The phase transformation was based on quantification of the calcite content at various temperatures using Rietveld refinement analysis. The results show that the

Flexible minerals: self-assembled calcite spicules with extreme bending strength.

Filipe Natalio et al.

Science (New York, N.Y.), 339(6125), 1298-1302 (2013-03-16)

Silicatein-α is responsible for the biomineralization of silicates in sponges. We used silicatein-α to guide the self-assembly of calcite "spicules" similar to the spicules of the calcareous sponge Sycon sp. The self-assembled spicules, 10 to 300 micrometers (μm) in length

Surviving rapid climate change in the deep sea during the Paleogene hyperthermals.

Laura C Foster et al.

Proceedings of the National Academy of Sciences of the United States of America, 110(23), 9273-9276 (2013-05-22)

Predicting the impact of ongoing anthropogenic CO2 emissions on calcifying marine organisms is complex, owing to the synergy between direct changes (acidification) and indirect changes through climate change (e.g., warming, changes in ocean circulation, and deoxygenation). Laboratory experiments, particularly on
