Jon Ihlefeld, a Distinguished Member of the Technical Staff at Sandia National Laboratories, has been selected to receive the 2017 Richard M. Fulrath Award from The American Ceramics Society. Jon was selected by unanimous decision for his contributions to electronic ceramics research and development. This award recognizes individuals under the age of 45 that have demonstrated excellence in research and development in the ceramics sciences. Presented to 2 American researchers and 3 Japanese researchers annually since 1978, this award promotes technical collaboration among the diverse cultures surrounding the Pacific Rim. Dr. Ihlefeld is internationally recognized for his work on ferroelectrics, funded, in-part, by the Laboratory Directed Research Development Office at Sandia, dielectric integration, funded, in-part, by the Office of Electricity’s Energy Storage Program managed by Dr. Imre Gyuk, and fast ion conductors, funded, in-part, by the Office of Nuclear Energy. The award will be presented at the 119th annual meeting of The American Ceramics Society, in Pittsburg PA, October 9th, 2017.
Through the Secure and Sustainable Energy Future Mission Area, Sandia National Laboratories seeks to support the creation of a secure energy future for the US by using its capabilities to enable an uninterrupted and enduring supply of energy from domestic sources, and to assure the reliability and resiliency of the associated energy infrastructure. SNL seeks to create an energy future that is also sustainable by using its capabilities to drive the development and deployment of energy sources that are safer, cleaner, more economical and efficient, and less dependent on scarce natural resources.

Accelerating Low-cost Plasma Heating and Assembly (ALPHA) Project Demonstrating Fuel Magnetization and Laser Heating Tools for Low-Cost Fusion Energy
Partners: University of Rochester
Project Innovation + Advantages:
Sandia National Laboratories is partnering with the Laboratory for Laser Energetics at the University of Rochester to investigate the behavior of the magnetized plasma under fusion conditions, using a fusion concept known as Magnetized Liner Inertial Fusion (MagLIF). MagLIF uses lasers to pre-heat a magnetically insulated plasma in a metal liner and then compresses the liner to achieve fusion. The research team will conduct experiments at Sandia’s large Z facility as well as Rochester’s OMEGA facilities, and will collect key measurements of magnetized plasma fuel including temperature, density, and magnetic field over time. The results will help researchers improve compression and heating performance. By using the smaller OMEGA facility, researchers will be able to conduct experiments more rapidly, speeding the learning process and validating the MagLIF approach. Sandia’s team will also use their experimental results to validate and expand a suite of simulation and numerical design tools to improve future fusion energy applications that employ magnetized inertial fusion concepts. This project will help accelerate the development of the MagLIF concept, and assist with the continued development of intermediate density approaches across the ALPHA program.
Multi-Modal Monitoring of Plant Roots for Drought and Heat Tolerance in the U.S. Southwest – $2,400,000
The Sandia National Laboratories team will develop a set of technologies to link below ground carbon partitioning with aboveground photosynthetic measurements. They will use microneedle sensor technology, originally developed for medical applications such as glucose level monitoring, to non-destructively measure the transport and composition of plant sap and products of photosynthesis in the field. In addition, they will measure the soil chemistry near the root zone with a micro-gas chromatograph, a device used to separate and analyze individual compounds. Using data analytics and modeling, they will link these measurements together to find aboveground proxies for below ground processes. If successful, the project will allow for the selection of improved sorghum varieties with increased root biomass without excavation of roots.

By creating a dense layer with three types of polymer molecules bound to a surface, we have demonstrated unique self-assembled patterns both theoretically and experimentally.
Significance and Impact
Programmable polymer domains can be used to template novel electronic or photonic material, for example to precisely place quantum dots for controlled energy transfer. Polymer domains on nanoparticles can control their assembly to create new responsive materials.
Self-consistent field theory (SCFT) was used to calculate the self-assembled patterns and phase diagram for ternary mixtures of surface-bound polymers.
Ternary polymer monolayers were synthesized by polymerizing from a surface and shown to form laterally-phase separated domains in agreement with theory.

Pressure modulates balanced interactions in self-assembled nanoparticle arrays (a), enables formation of 1-3 dimensional nanostructures (c). In-situ structural (d,e) and optical (f) interrogation show correlation and consistency with phase transition processes (e,g) and formation of the nanostructures (c).
Pressure-Directed Assembly modulates nanoparticle interactions, enables ‘reversible and adjustable’ mesoscale assembly and exploration of collective physical characteristics for design and fabrication of novel nanoelectronic and photonic materials.
Significance and Impact
Exerting pressure-dependent control over nanoparticle arrays provides a unique and robust system to understand collective physics and to control optical property and energy transfer (Au, Ag, CdSe, FePt, etc.).
–Below threshold pressure, the interparticle spacing and resulting surface plasmon coupling were systematically and reversibly tuned.
Above threshold pressure, nanoparticles consolidated into 1-3 dimensional novel nanoelectronic and photonic materials (e.g., nanorods, nanowires, nanosheets, etc.)
