MDI is continuing research in collaboration with scientists at the Advanced Photon Source, Argonne National Laboratory.
This work is focused on materials in extreme conditions and includes experiments on nuclear fuels and a new project to combine
small and wide angle x-ray scattering to help understand how the atoms in liquids, glasses and very hot solids rearrange as
the temperature is changed. MDIs proposed experiments on molten oxides are selected for the Space Station please see link
to the NASA press release in the sidebar. The research involves development of experiments to measure the viscosity of liquids
and help to understand the nature of glass formation and the behavior of supercooled molten materials. Work is ongoing to
develop computer-based control of our acoustic levitators. This development includes investigation of amorphous pharmaceutical
materials. We are building instruments for several customers and will be delivering instruments later this year.
MDI and Argonne National Lab were recently invited to Adler After Dark at the Adler Planetarium where we showcased
our Single-Axis Acoustic Levitator as part of Back to the Future night. We had a great time demonstrating our tech to the
public and explaining the underlying science to all who were interested. More spectacularly, MDI was invited out to Los Angeles
to film two awesome videos over the summer! With Destin Sandlin of Smarter Every Day on YouTube, we explained how acoustic
levitation works and captured some amazing high speed footage using two Phantom cameras. Destin was so great to work with
and the footage is spectacular; it's linked on our homepage if you missed it. At the same time, we filmed a bit for American
Idol Season 14. In a short segment sponsored by Ford, the singers met with Destin, learned some science, and got to experiment
with MDI's Single-Axis Acoustic Levitator themselves! Of course it's not all fun and games at MDI, as we've also been very
busy developing new features for our products and our customers. We've got some exciting new capabilities that we just can't
wait to announce soon!
MDI is continuing basic and applied instrument development research to develop instruments for materials processing
in extreme conditions. Recent accomplishments include implementation of XANES (X-ray Absorption Near-Edge Structure) high
energy x-ray diffraction measurements at the Advanced Photon Source to investigate iron oxidation state in molten geological
materials. MDI staff are presenting papers at upcoming conferences, including ACerS GOMD-DGG 2015, PNCS XIV, and the SGT Annual
Conference (links on the right). We've been putting our new 3D printer to good use making handy accessories, prototypes, and
mockups for planned experiments on molten nuclear energy-related materials.
MDI scientists, in collaboration with Argonne National Laboratory and Stony Brook University, have published the results
of structure measurements on molten titanium dioxide and uranium dioxide in Physical Review B and Science, respectively. These
findings come from recent experiments utilizing MDI's unique HT-CNL™ system through MDI's continued mission to support
research on extreme condition materials at both the Advanced Photon Source at Argonne National Laboratory and the Spallation
Neutron Source at Oak Ridge National Laboratory. MDI also delivered and installed two SAL™ instruments to commercial
clients in Japan and the UK.
MDI completed successful beamline campaigns at the Advanced Photon Source at Argonne National Lab in Illinois and
the Spallation Neutron Source at Oak Ridge National Lab in Tennessee to study various high temperature melts, including molten
MDI installed HT-CNL systems in the Department of Physics at Coe College in Cedar Rapids, IA and also at Oak Ridge
National Laboratory's Spallation Neutron Source in Oak Ridge, TN. Both instruments are being used for research on liquids
and glasses. The instrument at Oak Ridge will also be used at their high flux neutron beamlines to make in-situ structure
measurements on liquids. The planned new structure measurement capability will complement an existing system at the Advanced
Photon Source, Argonne National Laboratory.
MDI completed a Phase I SBIR project by the National Institutes of Health and it is working on a Phase II project
to commercialize our image plate technology. The objective of the project is to produce and scale up optical quality fluoride
glass plate materials. The glasses can be doped with optically active ions and heat treated to form materials that can store
X-ray images. The process exploits a photostimulable luminescent (PSL) effect in the glasses. After exposure to X-rays, the
plate can be read using a laser device. Compared to other methods, the new technology provides high resolution and lower X-ray
dosages for patients in procedures such as mammography. In addition, the use of glass plates offers cost advantages over competing
digital techniques. MDIs experience in glass development is being used to optimize glass processing and properties to make
image plates up to 24 x 30 cm in size.
The new project complements collaborations with researchers at The University of
Tennessee, Stony Brook University, The University of Chicago and The University of Paderborn.
MDI's HT-CNL at Argonne National Laboratory's Advanced Photon Source was used to investigate the structure of undercooled
melts that can undergo liquid-liquid phase transitions. The research is part of an international collaboration between scientists
based in the UK, France, and the USA. The work is published in the journal Science (Vol. 322, pp. 566-570, 2008 and This Week
in Science Vol. 322, pp. 501, 2008). A related News and Views article appears in Nature Materials (Vol. 7, pp. 843-844, 2008).
