The applied ends of the URI on advanced cryogenic propellants, namely the feasibility of preparing cryogenic materials with higher energy density than systems presently in use, have been met with two examples solid hydrogens doped with atomic oxygen, and solid oxygen doped with atomic oxygen. Both of these systems have been demonstrated in the laboratory, and in the latter case, where doping number densities of order 1 have been achieved, a patent has been filed on the Method for producing High Energy Density Cryogenic Fuel. Additionally, methods of characterization, including quantitative calorimetry and spectroscopy, have been devised and implemented. The original proposal recognized the need for developing a fundamental scientific basic for such intended applications. There has been significant progress in this regard, developments that go beyond the immediate target of the URI. Practical methods for computation of energetics and dynamics in quantum hosts, and quantum many-body dynamic in extended systems, were developed and successfully applied. The rheology of solid hydrogens was studied, and characterized. Time resolved spectroscopic methods were devised and implemented to demonstrate that microscopic details inaccessible in frequency domain spectroscopy of condensed media, could be unraveled with unprecedented detail.
