Selective Adsorption and Chiral Amplification of Amino Acids in Vermiculite Clay -Implications for the origin of biochirality
Donald G. Fraser, Daniel Fitz, Thomas Jakschitz +1
Smectite clays are hydrated layer silicates that, like micas, occur naturally in abundance. Importantly, they have readily modifiable interlayer spaces that provide excellent sites…

Chiral Interactions of Histidine in a Hydrated Vermiculite
Donald G. Fraser, H. Christopher Greenwell, Neal T. Skipper +4
Recent work suggests a link between chiral asymmetry in the amino acid iso-valine extracted from the Murchison meteorite and the extent of hydrous alteration. We present the result…

Water Chemisorption and Reconstruction of the MgO Surface
K. Refson, R. A. Wogelius, D. G. Fraser +3
The observed reactivity of MgO with water is in apparent conflict with theoretical calculations which show that molecular dissociation does not occur on a perfect (001) surface. We…
