Thanksgiving news: Nanotechweb reported our research results on preparation of Sm-Co nanoparticles by
assisted ball milling (in pdf)
(in html). Sm-Co hard magnetic nanoparticles with room-temperature coercivity have been successfully produced using a surfactant-assisted ball
milling technique by Yiping and co- workers in our UTA-Experiment Group. The results are published in Nanotechnology (in pdf).
Our second annual review meeting was held at University of Maryland, College Park, on September 11-12, 2007. The program managers, Dr. Mihal Gross,
Dr. John Prater, and Dr. Harold Weinstock attended the meeting. All the PIs and postdocs and students from the seven
groups presented their research results in oral presentations and posters to show our major progress made in the
past year. Nine experts of our Advisory Committee from Naval Research Laboratory, Ames National Laboratory, Sandia National Laboratory, EEC Inc. and University of Texas-Arlington are invited to attend the meeting. Our University of Maryland group did excellent job in hosting this review meeting.
On August 29, 2007, NanotechWeb reported our research progress in
warm compaction of bulk nanocomposite permanent magnets. This
project has been carried out by our UTA experimental group in
collaboration with the MURI team and
the NanoTech Institute at the
University of Texas at Dallas. It has been a great challenge to directly
compact nanoparticles with particle size down to few nanometers. The
warm compaction is a new method developed in the UTA group for
fabrication of bulk nanocomposite magnets as one of the key techniques in
our bottom-up approach to production of nanostructured bulk
materials (in pdf) (in html).
Our first annual review meeting was held at
Brown University on September 19-20, 2006. The program managers, Dr. Mihal Gross and Dr. John Prater, and all the PIs and postdocs and students attended the meeting. Each group presented their major research results in oral presentations and posters
which showed that great progress has been made in the past year. Our Brown University group did excellent job in hosting this review meeting.
The Rare-earth Magnets Workshop was
held successfully in Sheraton hotel, Boston on November 27, 2005,
from 8:00AM to 6:00PM. Six speakers including four invited speakers
gave tutorials which cover many fundamental and manufacturing
aspects of the rare-earth transition-metal permanent magnets. The
speakers and topics were:
Dr. Shu-Fan Cheng, Naval Research
The development and
DoD applications of rare-earth
transition-metal permanent magnets
Dr. Christina Chen, University of
magnets and Reduction-Diffusion technique for production of SmCo and
Dr. Hao Zeng, University at Buffalo
Magnetism in nanoparticles
Dr. Samuel Jiang, Argonne National
Magnetization reversal and coercivity in
Our team members and the speakers.
Dr. Z.Q. Jin, Arnold Magnetic
Rapidly quenched NdFeB and SmCo magnets and processing
of bulk nanostructured magnets.
Dr. J. P. Liu, University of Texas
Magnetic interactions in rare-earth transition-metal
Fruitful discussions and exchanges
accompanied the presentations throughout the meeting. After the
tutorials, Dr. Ping Liu gave a brief quarterly review of our MURI
project. All the newly joined team members then gave 10-15 minute
presentation each to introduce themselves and talk about their
research results and plans.
This was the first gathering after
our Kick-off Meeting and was a “big union” of the team. All the
principal investigators and the postdocs and students involved to
the MURI project were in the meeting. We had a “union picture” (see
above). Dr. John Prater from Army Research Office, one of our
project review committee members attended the whole meeting.
Everyone felt that this workshop is very helpful to our teamwork.

Physics Web Reports on Synthesis of
. On August 4, 2005,
Physics Web reported our recent research
achievement in the synthesis of ferromagnetic FePt
nanoparticles. "Physicists in the US have developed a simple way to
make nano-sized particles with potentially useful magnetic properties", the report said.
Prof. Kevin O'Grady of York University evaluated the progress as "quite a remarkable
result". With this creative technique, monodisperse FePt nanoparticles can be produced just by adding table salt to the raw particles before heat treatments. The produced ferromagnetic nanoparticles can be used as building blocks for magnetic recording media and high performance permanent magnets. The particles can also be used directly in biomedical applications. This work was led by Prof. J. Ping Liu and Kevin Elkins, Daren Li, Narayan Poudyal, Vikas Nandwana, Zhiqiang Jin and Kanghua Chen have contributed to the project. (in

the paper in Dr. Liu's group, titled "Monodisperse
face-centered tetragonal FePt nanoparticles with giant coercivity",
has been selected by Institute of Physics Publishing for inclusion in
IOP Select. IoP Select is a special
collection of journal articles, chosen by IOP Editors based on one or
more of the following criteria: substantial advances or significant
breakthroughs; a high degree of novelty; significant impact on future
research. "The service reflects both the breadth and international
significance of papers published in our prestigious research journals
and provides even greater visibility for our authors" said Dr. Nina
Blakesley, Publishhing Administrator of Journal of Physics D: Applied
project Kick-Off meeting was held at University of Texas at Arlington
on April 26-27, 2005.
The meeting starts with a welcome talk by Prof. Paul Paulus,
Dean of UTA College of Science. Attendants of this meeting include
Dr. Mihal Gross, manager of
Physical Science S&T Division, Office of Naval Research (ONR),
Browning, program manager at the Defense Advanced Research Projects Agency
Defense Science Office (DSO), and
John Prater associate director of Material Science Division at Army Research Office (ARO).
Dr. Liu, the Principal Investigator, gave a presentation on "Synthesis and

The Department of Defense (DoD)
on February 28, 2005, announced plans to award 33 research grants to 27
universities totaling about $15 million in fiscal year 2005 and about $29.2
million per year starting in fiscal year 2006 for a total of $146.6 million
over five years. These academic institutions, including UT-Arlington led team, will
receive the grants to conduct multidisciplinary research in 26 topic areas
of basic science and engineering which will be made under the DoD Multidisciplinary University Research Initiative (MURI) program.
All awards are subject to
the successful completion of negotiations between DoD research offices and
the academic institutions.
The MURI program is
designed to address large multidisciplinary topic areas representing
exceptional opportunities for future DoD applications and technology
options. The awards will provide long-term support for research, graduate
students and laboratory instrumentation development that supports specific
science and engineering research themes vital to national defense.
The average award will be
$900,000 a year over a three-year period. Two additional years of
funding will be possible as options, bringing the total award to five
years. Out-year funding is subject to satisfactory progress in the research and the availability of funding appropriations.
This announcement is the
result of a rigorous competition over many months under the MURI program.
In response to the MURI broad agency announcement solicitation, many letters
of intent to submit proposals were received leading to 121 full proposals
which were evaluated by DoD technical expert teams. (http://www.defenselink.mil/releases/2005/nr20050228-2141.html).
