Do homochiral aggregates have an entropic advantage?

Article Abstract:

The study illuminated the underlying principles, which control the aggregation of chiral building blocks into larger aggregates by examining the role that entropy plays in this process. The model system predicts that the formation of a specific structure is more likely to occur from an enantiopure solution because forming a particular structure from a racemic solution in hindered by significant entropic barriers.

Adsorption study of acetone on acid-doped ice surfaces between 203 and 233 K

Article Abstract:

Adsorption studies of acetone on pure ice surfaces obtained by water freezing or deposition or on frozen ice surfaces doped either with HNO3 or H2SO4 are performed using a coated wall flow tube coupled to a mass spectrometric detection. The results are discussed and used to reestimate the partioning of acetone between the ice and gas phases in clouds of the upper troposphere.

Determination of sequence-specific intrinsic size parameters from cross sections for 162 tripeptides

Article Abstract:

The cross sections of 162 tripeptide sequences are measured with ion mobility and mass spectrometry techniques. The sequence-specific intrinsic size parameters (SSISPs) are used in order to retrodict cross-section values for the 162 measured sequences and to predict cross sections for the remaining tripeptide, which are comprised of residues.
