Structure and hydration of L-proline in aqueous solutions
Article Abstract:
A combination of neutron diffraction with isotopic substitution, empirical potential structure refinement modeling and small angle neutron scattering at three concentrations are used to study the structure and hydration of L-proline in aqueous solution. The study results show the proline's weak interaction with other praline molecules in solution and its strong interaction with the surrounding water environment without significantly perturbing the bulk water structure.

Determining the role of hydration forces in protein folding
Article Abstract:
The efficiency of lattice models in explaining the folding mechanism of proteins may be enhanced through a comprehensive description of solvation forces involved in the process. By introducing physically motivated solvation terms, researchers may be able to account for amino acid diversity, which leads to a more facilitated folding transition and unique ground states. These models are currently being studied to expand their applications to off-lattice simulations.

Hydration of sodium, potassium, and chloride ions in solution and the concept of structure maker/breaker
Article Abstract:
The Empirical Potential Structure Refinement method is used for analyzing the neutron diffraction data with hydrogen isotope substitution on aqueous solutions of NaCl and KCl at concentrations ranging from high dilution to near-saturation. The distortions to the microscopic structure of water are due to the combined effect of the cation-anion pair, thus eliminating the importance of the definition of structure maker/breaker referred to a single ion.
