Reliable prediction of freezing point depression in liquid electrolytes will accelerate the development improved Li-ion batteries which can operate low temperature environments. In this work we establish a computational methodology to calculate activity coefficients and liquidus lines for battery-relevant electrolytes. Electronic structure methods are used conjuction with classical molecular dy...

Laboratory experiments show that undercooling to about -5 degrees C occurs in colonized Beacon sandstones of the Ross Desert, Antarctica. High-frequency temperature oscillations between 5 degrees C and -5 degrees C or -10 degrees C (which occur in nature on the rock surface) did not damage Hemichloris antarctica. In a cryomicroscope, H. antarctica appeared to be undamaged after slow or rapid ...

Acidified steam condensates that are enriched in SO4 but poor in Cl are found in the upper parts of many geothermal systems occurring in steep terrains. In this paper, we characterize the chemical evolution of these acid-sulfate fluids by combining mineral and fluid inclusion relationships from Karaha-Telaga Bodas with numerical simulations of water-rock interactions. These interactions were mo...

We report the synthesis and activity of new mononuclear and dinuclear gold amide complexes 1-7. The dinuclear complexes 6b and 7 were characterised by single crystal X-ray analysis. We also report solution NMR and freezing point depression experiments to rationalise their behaviour in solution and question the de-ligation process invoked in gold catalysis.
