Chiral Biases in Solids by Effect of Shear Gradients: A Speculation on the Deterministic Origin of Biological Homochirality
We present an experimental approach to the study of the chirality of three CM2 meteorite solid samples by direct measurement of the optical activity (circular birefringence; CB). The measurements are based on ...

Chemical Abundances of Cometary Meteoroids from Meteor Spectroscopy
The overabundance of comets and chondritic bodies during the first stages of the primitive Solar System produced a constant rain of material over our planet, which might have direct implications to the origin ...
