• Vaterite: Crystal within a crystal helps resolve an old puzzle

  With the help of a solitary sea squirt, scientists have resolved the longstanding puzzle of the crystal structure of vaterite, an enigmatic geologic mineral and biomineral. A form of calcium carbonate, vaterite can be found in Portland cement. Its quick transformation into other more stable forms of more

• Tooth enamel restoration inspired by mother of pearl

  Researchers in China have shown that the organic component of mother of pearl can help repair damaged teeth, by acting as a template for the mineralisation of tooth enamel. Tooth enamel is made up of rod-like crystals of hydroxyapatite, a calcium phosphate mineral. It is the hardest tissue in the bo more

• Biomimetic bricks inspired by nacre

  Chinese chemists have developed a new nacre-like material which is stronger than natural nacre (mother of pearl). Nacre is a naturally occurring composite formed from calcium carbonate and biopolymers which create a brickwork structure. It is also nearly a thousand times stronger than any of its com more

• Measuring particle size using modern laser diffraction techniques
  

  Many different techniques have been devised for determining particle size distribution, but for a wide range of industries laser diffraction has become the preferred choice. Laser diffraction, alternatively referred to as Low Angle Laser Light Scattering (LALLS), can be used for the non-destructive analysis of wet or dry samples, with particles in the size range 0.02 to 2000 micron and has inherent advantages which make it preferable to other options for many different materials. more

• “Metakaolin‐Slag‐Clinker Blends.” The role of Na+ or K+ as Alkaline Activators of Theses Ternary Blends

  This article reports on research into the use of solid alkalis (Na2CO3 and K2CO3) as activators to obtain hybrid cement (cement whose hydration generates a mix of C–A–S–H and (N,C)–A–S–H gels) from a blend of 20% clínker + 40% blast furnace slag + 40% metakaolin. More specifically, the study aimed more

• Monodisperse Spherical CaCO3 Superstructure Self-assembled by Vaterite Lamella under Control of Regenerated Silk Fibroin via Compressed CO2

  In this paper, spherical calcium carbonate (CaCO3) with ordered lamella nanostructure were prepared by using regenerated silk fibroin (RSF) as a crystal modifier via compressed CO2.The crystal morphology could be tuned from lens-like to spherical by altering RSF concentration, reaction time, and tem more

• Structural Characterization of Amorphous Calcium Carbonate-Binding Protein: Insight into the Mechanism of Amorphous Calcium Carbonate Formation

  Amorphous calcium carbonate (ACC) plays an important role in biomineralization process for its function as a precursor for calcium carbonate biominerals. However, it is unclear how biomacromolecules regulate the formation of ACC precursor in vivo. Here, we used biochemical experiments coupled with b more
