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.

The hydration of calcium sulphate hemihydrate (CaSO4.0,5H2O) leads to gypsum (calcium sulphate dihydrate – CaSO4.2H2O). It is a highly exothermic reaction which occurs by a dissolution/reprecipitation mechanism: when the hemihydrate is mixed with water, a fraction of it dissolves to give a saturated solution with respect to Ca2+ and SO4 2- ions, which is supersaturated with respect to calcium sulfphate dihydrate leading to nucleation and crystal growth. ESEM images taken from the hemihydrate hydration process. One can follow water adsorption to the hemihydrate at a 100% RH and the resulting needle-like crystals which result after water elimination.

Shot peening of Ti-45Al-10Nb in air leads to partial amorphisation of the outermost layer and to the formation of a contaminant nanocrystalline (T, Al)N phase, presumably Ti2N. The figure shows dislocation recovery within a nano-crystalline grain embedded into the amorphous phase of the shot peened surface layer, as observed in situ. Three dislocations are marked by symbols. Stage (i): The isolated dislocation on the left hand side is relatively immobile. The two other dislocations are in a dipole configuration and propagate towards each other and are about to annihilate in stage (ii). Stage (iii) shows the situation after annihilation of the dipole dislocations; this is indicated by the continuous trace of the lattice planes. Observations made at room temperature with an acceleration voltage of 300 kV. It should be noted that the micrographs were sligthly compressed along the vertical direction in order to make the dislocations readily visible. The figure demonstrates the high electrical, thermal and mechanical stability of the instrument.
