Over the past two decades there has been heightened concern about, and an improving
scientific description of, the impacts of increasing carbon dioxide concentrations in Earth's …

Nanotechnology enables the design of materials with outstanding performance. A key
element of nanotechnology is the ability to manipulate and control matter on the nanoscale …

Modification of calcium carbonate particles with surfactant significantly improves the
properties of the calcium carbonate coating on paper. In this study, unmodified and CTAB …

We report an experimental and microstructural study of the frictional properties of simulated
fault gouges prepared from natural limestone (96% CaCO 3) and pure calcite. Our …

Early stage amorphous precursors provide a low energy pathway for carbonate
mineralization. Many natural deposits of carbonate minerals and biogenic calcium …

Flotation separation of carbonate minerals is difficult because of their similar surface
properties. A variety of collectors and depressants have been previously used to improve …

Calcium carbonate is a common constituent of many natural materials, such as shells and
skeletons of marine animals. While it is well-documented that additives (organic and …

Calcium carbonate precipitation proceeds via a complex multistage scenario involving
neutral ion clusters as precursors and amorphous phases as intermediates, which finally …

Understanding the internal mechanisms controlling fault friction is crucial for understanding
seismogenic slip on active faults. Displacement in such fault zones is frequently localized on …

Calcium carbonate, particularly in the form of calcite, is an abundant mineral widely used in
both human-made products and biological systems. The calcite surface possesses a high …
