Nano‐Powdered Calcium Carbonate Reference Materials: Significant Progress for Microanalysis?

Microanalysis of Materials Using Synchrotron Radiation

Hydrogels from Amorphous Calcium Carbonate and Polyacrylic Acid: Bio-Inspired Materials for "Mineral Plastics".

Given increasing environmental issues due to the large usage of non-biodegradable plastics based on petroleum, new plastic materials, which are economic, environmentally friendly, and recyclable are in high demand. One feasible strategy is the bio-inspired synthesis of mineral-based hybrid materials. Herein we report a facile route for an amorphous CaCO3 (ACC)-based hydrogel consisting of very ...

Newly Developed Nano-Calcium Carbonate and Nano-Calcium Propanoate for the Deacidification of Library and Archival Materials

Paper-based cultural heritage objects are subject to natural deterioration due to internal and external factors, that is, the presence of heavy metals, incorrect conservation, humidity, exposure of the artifacts to pollutants, light, and high temperatures. To contrast the decay of the original objects, it is necessary to study and apply innovative specific techniques, set up novel preservation ...

Natural calcium carbonate for biomedical applications

i ii iii iv Dedicated to my mother… v ACKNOWLEDGEMENTS This thesis would simply not have been possible without the work, guidance and endless belief and support of my guide Dr. S. Vijayalakshmi. She really did show me what it takes to pursue research and kept me going. Her patient, modest and kind nature helped me understand and do better. Her warm words of appreciation and encouragement made m...

Calcium carbonate-calcium phosphate mixed cement compositions for bone reconstruction.

The feasibility of making calcium carbonate-calcium phosphate (CaCO(3)-CaP) mixed cements, comprising at least 40% (w/w) CaCO(3) in the dry powder ingredients, has been demonstrated. Several original cement compositions were obtained by mixing metastable crystalline CaCO(3) phases with metastable amorphous or crystalline CaP powders in aqueous medium. The cements set within at most 1 h at 37 de...
