Siderite Pyramids

Capturing and storing carbon dioxide (CO2) and other greenhouse gases deep underground is one of the most promising options for reducing the effects of energy production on the earth. Scientists at PNNL are using electron microscopes to understand the reaction of CO2 and minerals found underground. SEM image shows the aftermath of fayalite reacting with supercritical CO2 to form siderite, thereby capturing the CO2 in a solid, stable form. Research was funded by the U.S. Department of Energy.

Nanostructured hydroxyapatite

Nanostructured hydroxyapatite powder with biopolymers. Microparticles formed by nanoparticles of hydroxyapatite crystals, with needle shape and stabilized with polymer surfactants, resulting in a structure similar to a blackberry. In the field of regenerative medicine, there is a great use of this biomaterial due to the similarity to the main inorganic constituent of natural bone and teeth. The synthetic hydroxyapatite has excellent biocompatibility and bioactivity to be used as a suitable bone substitute.
