Wong. “Self-Organized Gels in DNA/F-Actin Mixtures without Crosslinkers: Networks of Induced Nematic Domains with Tunable Density”, Phys. Rev. Lett. 2008, 218303 Fundamental understanding of self- assembly in water requires knowledge of water structure at the nanoscale. In an NSEC collaboration, RPI and UIUC researchers employed a combination of experimental and computational methods to reconstruct the behavior of water measured via synchrotron X-rays. As a result, the space- and time- The evolution of hydration structure around a point charge as it accelerates harmonically to 500m/s in 500 femtoseconds. dependent behavior of water at femtosecond timescales and Ångström lengthscales can be simultaneously known for the first time. An understanding of electrostatic interactions in water is important for a wide range of applications, including gene therapy, cancer vaccines, water purification technologies, and the development of antimicrobial agents.
