Due to the high rates of consumption of minerals and the high human population growth, mineral resources on planet Earth are in the process of exhaustion, this shortage creates the need to fi nd new alternatives to supply ...
The impacts of profit-based royalties on early-stage mineral exploration Emilio Castillo
(Elsevier, 2021)
The impact of public policy on the mineral industries is difficult to measure due to little short-term
responsiveness to policy changes by companies already investing in known fixed deposits. Nevertheless, earlystage (or ...
Ultrastructure of early mineral deposition during hyaline layer formation in rat molars
(Elsevier B.V., 2001-04-01)
There is no consensus on whether the first mineralized layer, the hyaline layer, that is juxtaposed to root dentine is a variety of dentine or cementum or even a tissue of epithelial origin. Some suggest that there is no ...
Surface-Directed Mineralization of Fibrous Collagen Scaffolds in Simulated Body Fluid for Tissue Engineering Applications
(2021-03-15)
The use of polymer additives that stabilize fluidic amorphous calcium phosphate is key to obtaining intrafibrillar mineralization of collagen in vitro. On the other hand, this biomimetic approach inhibits the nucleation ...
