Chemical analysis of the Water-rock interaction showed that hydrothermal altered rock contains large amount of fluoride. Considering that alteration has mainly occurred at the fractures’ cleavages, the aim of this paper is to investigate the change of the mineral composition between the cleavages and other parts of the granite surfaces. Scanning electron microscope with energy-dispersive spectr...

Although forsterite (Mg₂SiO₄) possesses good biocompatibility and suitable mechanical properties, the insufficient bioactivity and degradability hinders its further application. In this study, a novel MgO-CaO-SiO₂ system was developed by adding wollastonite (CaSiO₃) into Mg₂SiO₄ to fabricate bone scaffolds via selective laser sintering (SLS). The apatite-forming ability and degradability of the...

CO2 conversion to calcium and magnesium carbonates has garnered considerable attention since it is a thermodynamically downhill pathway to safely and permanently sequester large quantities of CO2. This seminal work performed at The National Energy Technology Laboratory in Albany (NETL-Albany) reports the conversion of calcium-and magnesium-bearing silicate minerals, such as olivine [(Mg, Fe)2Si...

Here, we show the importance of the marine biomaterial chitin and its derivative, chitosan, in bioimplant applications. Titanium and titanium alloys have shown high potential for load bearing in bioimplant applications. However, after their application, a bond with living bone often does not develop or the integration of the implants with bone tissue takes several months. Moreover, the surface ...

The solubility and stability of synthetic grossular were determined at 800 C and 10 kbar in NaCl–H2O solutions over a large range of salinity. The measurements were made by evaluating the weight losses of grossular, corundum, and wollastonite crystals equilibrated with fluid for up to one week in Pt capsules and a piston-cylinder apparatus. Grossular dissolves congruently over the entire salini...
