Laboratory Directed Research and Development Program FY 2004 Annual Report
The Oak Ridge National Laboratory (ORNL) Laboratory Directed Research and Development (LDRD) Program reports its status to the U.S. Department of Energy (DOE) in March of each year. The program operates under the authority of DOE Order 413.2A, 'Laboratory Directed Research and Development' (January 8, 2001), which establishes DOE's requirements for the program while providing the Laboratory Director broad flexibility for program implementation. LDRD funds are obtained through a charge to all Laboratory programs. This report describes all ORNL LDRD research activities supported during FY 2004 and includes final reports for completed projects and shorter progress reports for projects that were active, but not completed, during this period. The FY 2004 ORNL LDRD Self-Assessment (ORNL/PPA-2005/2) provides financial data about the FY 2004 projects and an internal evaluation of the program's management process. ORNL is a DOE multiprogram science, technology, and energy laboratory with distinctive capabilities in materials science and engineering, neutron science and technology, energy production and end-use technologies, biological and environmental science, and scientific computing. With these capabilities ORNL conducts basic and applied research and development (R&D) to support DOE's overarching national security mission, which encompasses science, energy resources, environmental quality, and national nuclear security. As a national resource, the Laboratory also applies its capabilities and skills to the specific needs of other federal agencies and customers through the DOE Work For Others (WFO) program. Information about the Laboratory and its programs is available on the Internet at <http://www.ornl.gov/>. LDRD is a relatively small but vital DOE program that allows ORNL, as well as other multiprogram DOE laboratories, to select a limited number of R&D projects for the purpose of: (1) maintaining the scientific and technical vitality of the Laboratory; (2) enhancing the Laboratory's ability to address future DOE missions; (3) fostering creativity and stimulating exploration of forefront science and technology; (4) serving as a proving ground for new research; and (5) supporting high-risk, potentially high-value R&D. Through LDRD the Laboratory is able to improve its distinctive capabilities and enhance its ability to conduct cutting-edge R&D for its DOE and WFO sponsors. To meet the LDRD objectives and fulfill the particular needs of the Laboratory, ORNL has established a program with two components: the Director's R&D Fund and the Seed Money Fund. As outlined in Table 1, these two funds are complementary. The Director's R&D Fund develops new capabilities in support of the Laboratory initiatives, while the Seed Money Fund is open to all innovative ideas that have the potential for enhancing the Laboratory's core scientific and technical competencies. Provision for multiple routes of access to ORNL LDRD funds maximizes the likelihood that novel and seminal ideas with scientific and technological merit will be recognized and supported
Summaries of FY 1997 Research in the Chemical Sciences
The objective of this program is to expand, through support of basic research, knowledge of various areas of chemistry, physics and chemical engineering with a goal of contributing to new or improved processes for developing and using domestic energy resources in an efficient and environmentally sound manner. Each team of the Division of Chemical Sciences, Fundamental Interactions and Molecular Processes, is divided into programs that cover the various disciplines. Disciplinary areas where research is supported include atomic, molecular, and optical physics; physical, inorganic, and organic chemistry; chemical energy, chemical physics; photochemistry; radiation chemistry; analytical chemistry; separations science; heavy element chemistry; chemical engineering sciences; and advanced battery research. However, traditional disciplinary boundaries should not be considered barriers, and multi-disciplinary efforts are encouraged. In addition, the program supports several major scientific user facilities. The following summaries describe the programs

Innovative Materials and Systems for Solid State Hydrogen Storage
The research presented in this doctoral thesis concerns with the development of novel
materials and systems for solid state hydrogen storage.
The first group of works presented is on alkaline and alkaline-earth borohydrides. The
possibility to enhance their properties with the help of nanosupports has been widely
explored. An attempt to improve the dehydrogenation kinetics of lithium borohydride has
been made dispersing this material on the surface of modified nanotubes and graphite.
The resulting nanoconfined material displayed a decreased decomposition temperature in
comparison with pure material and further decreasing was observed when the surface area
of the supports was increased. An analogous experiment was performed to investigate this
effect in combination with the assets of a reactive hydride composite, where two materials
are mixed to obtain a compound with a lower decomposition enthalpy. The effect of the
mixture was beneficial in presence of the support, due to lower temperature melting. For
calcium borohydride an ordered mesoporous carbon was used after chemical activation.
The increased properties of this support resulted in lower decomposition temperature and
improved reversibility for a number of cycles at different pressure values.
The second research line is focused on magnesium hydride. To improve its kinetic properties
a zirconium-nickel alloy was investigated to evaluate its influence on the reaction
rate, both in absorption and desorption. The degradation observed in experimental reactors,
of different magnesium hydride powders catalyzed with a transition metal oxide,
motivated the fabrication of pellets with the addition of a binding agent, to obtain mechanical
resistance, still allowing hydrogen diffusion. Each pellet was supposed to behave
as an independent system, so they were also tested in a small reactor. Several hydrogen
absorption/desorption cycles were performed to compare the behaviour of the small reactor
with the laboratory data obtained on smaller quantity of powdered and pelletized
specimens.
Finally, the feasibility of a vehicular hydrogen tank system was investigated using an
interstitial metal hydride as storage material. Apart from material basic characterization,
two different kinds of experiment were performed. Static tests (measurements with automatic
flow control and constant settings) were used to evaluate wether the requirements
for desorption are met by the tank set-up. Then, dynamic tests were designed and applied
on the tank, where the hydrogen flow was fluctuating following a hypothetical on-road
trial. It was possible to underline the heat management issues of high-demanding performances
and to analyze some solutions for that. Different cycles were carried out on the
tank to find the ideal setting for high average and peak flows in a realistic experiment
The Fourteenth Annual Conference YUCOMAT 2012: Programme and the Book of Abstracts
The First Conference on materials science and engineering, including physics, physical chemistry, condensed matter chemistry, and technology in general, was held in September 1995, in Herceg Novi. An initiative to establish Yugoslav Materials Research Society was born at the conference and, similar to other MR societies in the world, the programme was made and objectives determined. The Yugoslav Materials Research Society (Yu-MRS), a nongovernment and non-profit scientific association, was founded in 1997 to promote multidisciplinary goal-oriented research in materials science and engineering. The main task and objective of the Society has been to encourage creativity in materials research and engineering to reach a harmonic coordination between achievements in this field in our country and analogous activities in the world with an aim to include our country into global international projects.
Until 2003, Conferences were held every second year and then they grew into Annual Conferences that were traditionally held in Herceg Novi in September of every year. In 2007 Yu-MRS formed two new MRS: MRS-Serbia (official successor of Yu-MRS) and MRS-Montenegro (in founding). In 2008, MRS – Serbia became a member of FEMS (Federation of European Materials Societies)
