Psst- It's SUPERCONDUCTIVEITY, Folks! Dr Prelas H.P. URLs:

... Work is now being carried out on the hydration process, using both small and wide angle scattering, in order to follow the formation and changes that occur in the hydrated mixture, including intermediate and final phases formed, and the development of pores in the hardened cement paste.
Superconductivity remains an important research area, with support provided by the Midwest Superconductivity Consortium (MISCON). Work has been carried out in collaboration with S.K. Malik from the Tata Institute of Fundamental Research (Bombay, India), especially on Pr based compounds, which do not show superconductivity, but are otherwise comparable to the RBa2Cu3O7 compounds, with other rare earths, which do show superconductivity. In addition, preliminary work has started on Tl based high temperature superconductors in collaboration with the University of Kansas, in order to determine the location of F atoms substituting for O. Research has begun on non-cuprate supercondutors (BKBO) in collaboration with the University of Nebraska. This is the subject of a new proposal to MISCON, between MURR and Nebraska.
Single crystal neutron diffraction efforts have ben directed toward systems where combined X-ray and neutron data models can be refined simultaneously to measure valence electron density distributions. These results are compared with densities obtained from ab initio theoretical quantum calculations. In the past year efforts were concentrated on implementing the computer code CRYSTAL92 on the MU RS6000 computing network to permit the ab initio calculations for crystal lattices. The goal is to demonstrate that many of the important differences between measured and calculated electron densities can be resolved by adequately accounting for crystal lattice interactions in the theoretical models. In addition, the simultaneously refined X-ray/neutron single crystal diffraction model should emerge as the benchmark against which the theoretical methods are judged. Many of the studies must be performed at reduced temperature, and a high quality closed cycle refrigerator for single crystal diffraction should be implemented in the coming year. Coupled with the transfer of the Huber diffractometer to beamport A, this facility should provide high quality data with high data rates.
Other efforts in instrumentation have been directed towards the use of bent crystal monochromators, for the stress machine and for the high resolution powder diffractometer (HRPD). In the latter case, designs have been developed, which, when coupled to an augmented detector and improved primary beam optics, will lead to an order of magnitude gain in data acquisition and enhanced resolution. This will make the MURR HRPD the best steady state diffractometer in the U.S., if not the world, and will allow for full spectral collection on 1 gm specimens in as little as 2 hours. The detector improvements are indirectly supported by the Instrument Development group's work to provide a detector system for Kjeller (Norway), while the monochromator will be based on the construction of a similar system for Studsvik. In addition, the bent crystal techniques have been used to create a double crystal SANS system with high intensity and adjustable resolution. For many studies, such a system will complement the pin-hole SANS camera being installed, by allowing measurements to smaller q-vectors. A prototype system was built for and paid by Oak Ridge, and subsequent improvements were incorporated into a MURR system.

The research work of this group is focused primarily toward disordered (amorphous or crystalline) materials and materials with a substructure of order 10 or more lattice spacings. Included in this are physisorbed monolayer materials, porous structures, artificial superlattices of metals, polymers, and insulators, hydrogen absorption in elements and compounds, lipid bilayer biological systems, chlorophyll aggregates and nano-structured materials formed of a dispersion of one element in a dissimilar matrix.

Research Areas and Experiments
Inertial Electrostatic Confinement Fusion
For more information on this project, under development in conjunction with Daimler-Benz Aerospace (DASA), see dasa.com.
Dense Plasma Focus
The DPF uses a j x B force to accelerate a plasma sheath down a set of concentric electrodes. When the sheath reaches the end of the cathode/anode, an intense pinch occurs due to the curature of the field lines. High fusion reaction rates have been obtained during pulses 1011 time-averaged fusions/second.
The UI facility (named "Ziggy") has 40kJ/125kJ pulsing capability. Construction of the 250kJ advanced facility was stopped short due to lack of funding.
Interest for fusion space propulsion, neutron/proton sources, and tunable x-ray sources motivate DPF research.
Direct Energy Conversion/Nuclear Pumped Lasers
Much of the pioneering work on direct energy conversion has been done at FSL. Most notable is the subfield of Nuclear Pumped Lasers. By initiating direct excitation from nuclear collisions with neutrons directly from a reactor beamline, incredible efficiencies in lasing are the result.
With the UI advanced TRIGA research reactor, ample neutron peak neutron fluxes have yielded fantastic experiments and results. However, funding for such programs have dwindled in the past few years and NPL awaits further support.
Generalized Fusion Research
The FSL has collaborated on many projects in each of the different fields in fusion engieering:
Reversed Field Pinches
Z-Pinches
Spherical Tokamaks/Electric Tokamaks
Multipole/Dipole
Field Reversed Configurations
Stellerators
Magnetized Target Fusion
Spheromak
Laser-Driven Inertial Fusion
Light-Ion Fusion
Heavy-Ion Fusion
Cold Fusion

P.S.- The FOCUS and aims:
I quote:
Welcome
to the Department of Nuclear Engineering at the University of Illinois. The campus here in Urbana has an enrollment slightly higher than 36,000, nearly 7,800 of which are engineering students. Our very own Nuc E department has 55 undergraduate students and 50 graduate students.
The Nuclear Engineering department has a 1.5 MW steady state TRIGA reactor which is used to train reactor operators and also to perform irradiation experiments.
The department offers curricula leading to the M.S. and Ph.D. degrees in nuclear engineering. The M.S. program requiring 8 units of credit, including a required thesis, can be completed by a full time student in two semesters and a summer session; typically students on fellowships and half-time assistantships need an additional semester. Those who intend to continue study toward a Ph.D. must complete the qualifying exam, usually taken during the second year of study. Requirements for the Ph.D. include at least 8 units of course work beyond the M.S. At the conclusion of course work, there is a comprehensive oral exam emphasizing the students intended thesis research and examining readiness to conduct such research. Areas of research include both fission and fusion reactor engineering and technology; fusion plasma engineering; fusion-fission hybrid systems; fission reactor neutronics; shielding and radiation effects; thermal hydraulics and radiation safety; energy conversion; nuclear materials and radiation damage; reactor control and dynamics; environmental, safety, and public policy issues; fuel-cycle and waste management; and biomedical and health physics.
We are currently searching for a new faculty member. Click above to review the announcement.
