Unique properties of liquids and various processes in solutions originate from the solute-solute, solute-solvent, and solvent-solvent interactions in solutions. The structure and dynamics of liquids and solutions on the molecular level are thus essential for understanding the function and underlying mechanism of processes in solutions. Quantum beams, such as X-rays and neutrons, are of similar length and time scale as ions and molecules and are suited for this aim. Novel neutron scattering techniques for liquids and solutions have been developed for measurements over a wide range of concentration, temperature, and pressure. The techniques have been applied to various liquid systems, such as electrolyte solutions, supercritical fluids, confined and interfacial liquids, and solvent-induced denaturation of proteins.
