3:30 PM - SURF SUMMER SEMINAR SERIES: Time, Einstein and the Coolest Stuff in the Universe
At the beginning of the 20th century Einstein changed the way we think about Nature. At the beginning of the 21st century Einstein's thinking is shaping one of the key scientific and technological wonders of contemporary life: atomic clocks, the best timekeepers ever made. Such super-accurate clocks are essential to industry, commerce, and science; they are the heart of the Global Positioning System (GPS), which guides cars, airplanes, and hikers to their destinations. Today, atomic clocks are still being improved, using atoms cooled to incredibly low temperatures. Atomic gases reach temperatures less than a billionth of a degree above Absolute Zero, without freezing. Such atoms are at the heart of Primary Clocks accurate to better than a second in 80 million years as well as both using and testing some of Einstein's strangest predictions. This will be a lively, multimedia presentation, including experimental demonstrations and down-to-earth explanations about some of today's most exciting science.

10:30 AM - CNST NANOFABRICATION RESEARCH GROUP SEMINAR: Introduction of Functionalities into DNA Nanostructures
DNA has been intensively explored as a building block for nanoconstruction based on rational design and self-assembly. DNA nanostructures have been continuously evolved and there have been remarkable achievements. However, it remains challenging to introduce functionalities into such DNA nanostructures. DNA is potentially a good candidate for biomedical applications because it is biodegradable and a natural component of life systems. Recently our group has developed a DNA nanotube (DNA-NT) system with a single component, a 52-base-long DNA single strand.2 I have explored the use of DNA-NTs as drug carriers for cellular delivery.3 Functional agents (folate, a cancer cell target agent, and Cy3, model drug and imaging agent) are conjugated with DNA-NTs. The folate-conjugated DNA-NTs are effectively and selectively taken up by cancer cells because folate receptors are over-expressed on the cell surfaces of various cancer cells. RNA molecules are structurally close to DNA. Different from DNA, RNA has very rich chemical, structural, and functional diversities. I have developed a novel strategy to design and construct RNA nanostructures.4 This strategy is generally applicable and has been demonstrated by assembly of RNA into various well-defined nanomotifs, which can further assemble into extended or discrete large structures. I expect that this strategy will allow us to assemble various nanostructures with multi-functional RNA modalities.

ADVANCE NOTICE

7/14/09 10:30 AM - ATOMIC PHYSICS DIVISION SEMINAR: Material and Structural Enhancements to Spin-Transfer Efficiency for MRAM Applications
The discovery of the spin transfer effect has opened up possibilities for a new type of spin electronic device, in which small nanomagnetic elements are directly manipulated using spin polarized electric currents. Applications for these devices include uses as high-speed, non-volatile memory elements, as well as RF nano-oscillators for communication purposes. I will discuss the effect that different magnetic materials and device geometries can have on the micromagnetic structure generated within these nanomagnets. In particular, I will focus on a nanopillar geometry with tapered sidewalls, which acts to generate a spatially nonuniform spin current polarized partially out of the film plane. This strategy is shown, through both simulations and pulsed current experiments on devices fabricated by our group, to be effective in enhancing spin transfer efficiency, resulting in faster magnetization switching with lower reversal currents. In addition, I will discuss a novel nanopillar structure where a third electrode can be made to any point within a thin-film multilayer stack, substantially enhancing the versatility of the device by providing the means of applying independent electrical biases to two separate parts of the device. This three-terminal structure provides a strategy for developing high performance spin-torque magnetic random access memory cells which avoids the need to apply a large voltage across a MTJ during the writing step, thereby enhancing device reliability, while retaining the benefits of a high-impedance MTJ for read-out.

7/15/09 10:30 AM - CNST ELECTRON PHYSICS GROUP SEMINAR: ENABLERS FOR PROBE-BASED NANOMANUFACTURING AND NANOMETROLOGY
Of all the nanomechanical systems used, probes are perhaps the simplest, yet most indispensable tools used in the nanoscale research and development world today. At the nanoscale, quick and easy characterization tools are urgently needed to be able to deliver many technologies from their languid presence in the basement to the real world. Probe-based techniques are gaining prominence because they can be used to effectively probe both the surface, as well as the electrical characteristics at the nanoscale. In addition the same probe can be used to manipulate structures, and then re-image the manipulated region. Thus, any nanomanufacturing scheme will have to use probe-technologies at some level. In this talk, I will give an overview of my work within IBM in tackling some of these interesting issues. A brief introduction to probe-based data storage will be given, since this application embodies many of the challenges facing probe-based technologies. Some of my work on platinum silicide tips and "encapsulated" tips for conduction-mode probe-based technologies will also be presented. The performance of the encapsulated conducting tips in sliding is shown to be several times better than commercial conducting probes. Both these technologies have enabled us to perform effective nanoscale phase transformations in chalcogenide-based phase change materials - a proof of concept that probe-based nanometrology can be robust.

NIST MERCURY REDUCTION CAMPAIGN
The goal of the NIST Mercury Reduction Campaign is to remove all unneeded mercury from NIST facilities. We would like to minimize the potential for mercury spills, exposure to mercury, and releases to the environment. The toxicity of Mercury is well documented, particularly when exposure is by inhalation or absorption through the skin. A small amount of mercury can generate a significant airborne concentration, and mercury spills are fairly common at NIST - often due to broken thermometers or barometers. If a spill of mercury does occur, please contact the Safety, Health and Environment Division at x5818 or Fire Protection Services at x2222 for the proper clean up and disposal of the mercury. Please turn in any unneeded mercury or mercury-containing equipment for disposal/recycling to the Safety, Health and Environment Division. A pick up request can be prepared and submitted at: http://www-i.nist.gov/admin/ohsd/chemwast.htm. Call Mike Blackmon at x5822 with any questions. For information on mercury-free thermometers, please contact Dawn Cross in the Process Measurements Division at x4822.
