MEETINGS AT NIST

12/5 -- MONDAY

10:30 AM - MATERIALS SCIENCE AND ENGINEERING LABORATORY OFFICE SEMINAR: Low Speed Cracking in Vitreous Materials
This talk will be focused on the small velocity crack regime (stress corrosion) in vitreous material samples. An experimental setup allow us to track in-situ, in controlled atmosphere, the crack tip propagation with an atomic force microscope (AFM) at characteristic scales of the material structure heterogeneities. My talk will be composed of three parts: 1. Crack propagation in vitroceramics was studied by AFM according to their devitrification degrees. Variations with the rectilinear propagation were highlighted. In the most devitrified material, the crack pass round the nanometric crystals inducing torsion and shearing stresses, increasing material toughness. 2. The experimental highlight of the glass ductility phenomenon at the nanometric scales, appearing by damage nanocavities, is an innovative result establishing link between the crack mechanisms of ductile materials (metals) and brittle materials (glass). Difference takes place on length scale level of the cavities, respectively micrometric and nanometric. 3. Finally, cracking study of alkali containing glass reveals migration, at nanometric scale, of chemical species in the immediate vicinity of crack. The local mechanical stress field, the relative humidity as well as the residence time of the crack’s head in a given zone of the material, are essential parameters for the control of these diffusion phenomena at nanometric scale. The implied physicochemical processes were studied. The in-situ study of vitreous materials cracking at the characteristic heterogeneities scale is a key step for further understanding and improving glass mechanical properties. This material is nowadays more and more used in multiple fields.

10:45 AM - MATERIALS AND CONSTRUCTION RESEARCH DIVISION SEMINAR: Wireless Sensor Networks for Applications In and Around Buildings
Wireless technology has crept into many aspects of life, allowing communications without forcing the user to be tethered to a fixed location. One area where wireless radio transmission is beginning to create exciting opportunities for engineers and scientists is in wireless sensor networks. Small nodes that contain both sensors and radio transmitters promise to allow for simple deployment of measurement points throughout a region of interest by removing the expensive and obtrusive wiring needed to transmit signals back to a data-collection center. The benefits appear to be especially strong for those interested in studying or monitoring buildings, as sensors can be deployed to monitor comfort conditions, energy consumption, and safety issues within the buildings. This seminar will cover a number of sensor network technologies that are being developed and will assess the current state of the technology for those interested in using wireless sensor networks in studying phenomena in and around buildings. Lessons learned from a monitoring system deployed by BFRL will be presented, and efforts currently underway to ease the integration of these sensors into building applications will be discussed.

12/9 -- FRIDAY

10:30 AM - NIST COLLOQUIUM SERIES (JOINTLY SPONSORED BY SIGMA XI): Micro- and Nanofabricated Fluidic Devices for Chemical and Biochemical Experimentation
There are rapidly growing applications of microfabricated fluidic devices (microchips) for chemical and biochemical measurements. The types of samples are broad in scope, e.g., small ions and molecules, single and double stranded DNA, amino acids, peptides, and proteins. Recently there has been interest in shrinking channel lateral dimensions by a factor of ~ 1000, i.e., to molecular length scales. The fabrication of nanofluidic channels allows fundamental studies of transport at previously unexplored length scales and possibly the detection and characterization of single molecules. Examples will be given of various experiments that have been successfully transferred to these miniature platforms.

1:00 PM - SURFACE AND MICROANALYSIS SCIENCE DIVISION SEMINAR : Micro-Raman Spectroscopy to Determine the Full State of Stress of Silicon. Application to Eutectic Si Particles in Cast Al
Micro-Raman spectroscopy has been widely used to measure local stresses in silicon and other materials. However, a single (scalar) line position measurement cannot determine the complete stress state unless the stress is already known to have a very simple (1-parameter) form, such as uniaxial or hydrostatic. We describe new Raman experiments that take advantage of polarization, intensity, and frequency information. These experiments allow us to determine the full state of stress at the surface of silicon wafers under load. The experimentally measured values for ?xx, ?yy, and ?xy are in good agreement with those calculated from ABAQUS models. Combining Raman and finite element techniques, we examine several eutectic silicon particles in cast Al and measure residual stresses. We then make in-situ measurements of the rate of stress buildup in these particles due to load transfer from the Al matrix during tensile deformation. It is the fracture of eutectic Si particles that leads to the ductile failure of the cast Al. Our results are being used as input to a micromechanics code being developed to predict the ductility of cast Al.

2:30 PM - EPG NANOTECHNOLOGY SEMINAR SERIES : ***NOTE NEW TIME***ELECTRON TRANSPORT AT THE OUTER NANOMETER***NOTE NEW TIME
The nanoscale world is not a scaled-down version of the macroscopic world. Nanoscale structures have special properties by virtue of their smallness alone, which yields quantum confinement, high surface-to-volume ratio and susceptibility to fluctuations. Direct imaging at the atomic scale using scanned probe techniques allows the latter effect, fluctuations, to be observed and quantified. Quantitative characterization of these fluctuations using the tools of statistical mechanics yields correlation functions as well as more direct measures of stochastic behavior such as first-passage properties. The impact of nanoscale structural fluctuations on electrical transport will be illustrated for the case of electromigration on an ultra-thin silver fil

ADVANCE NOTICE

12/15/05 10:30 AM - MATERIALS AND CONSTRUCTION RESEARCH DIVISION SEMINAR: "Ductile Concrete"
Worldwide, reinforced concrete infrastructure faces challenges in three areas: Safety under natural and man-made severe loading, durability under normal service loads, and sustainability in harmonious existence with the natural environment. Under high rate blast or seismic loading, bond splitting and concrete spalling often compromise the integrity of a reinforced concrete structure. In many countries, deterioration of concrete infrastructure has forced more than fifty percent of construction outlays into expenses for repair and retrofit. The intense energy use and emissions of carbon dioxide into the atmosphere in cement production, combined with repeated repair needs in concrete infrastructure, lead to a decidedly unsustainable development of the built environment. This seminar presents an ultra ductile concrete – an Engineered Cementitious Composite (ECC) developed at the University of Michigan in the last decade, and which is rapidly gaining global acceptance. ECC has been designed to address the three major challenges of safety, durability and sustainability of reinforced concrete infrastructure. This seminar focuses on the design of ECC, findings on its damage tolerance under seismic and impact loading, highlights on durability attributes, and on sustainability characteristics when concrete is replaced by ECC in a bridge deck. Some recent full-scale structural applications of ECC are also presented.

12/16/05 10:30 AM - NIST COLLOQUIUM SERIES : Mars Direct: Humans to the Red Planet within a Decade
In July 1989, on the 20th anniversary of the Apollo Moon landing, the first President Bush called for America to establish a permanent lunar base and a series of human missions to Mars. While many have said this would be excessively costly and take many decades, a small team at Martin Marietta led by Dr. Zubrin drew up a daring plan that could sharply cut costs and send a group of astronauts to the Red Planet within ten years. Known as Mars Direct, the plan attracted international attention and broad controversy, and is once again at the center of the debate.

12/16/05 1:00 PM - CANCER NANOTECHNOLOGY SEMINAR: NANOTECHNOLOGY IN CANCER DIAGNOSIS AND THERAPY
Nanotechnology has the potential to have a revolutionary impact on cancer diagnosis and therapy. It is universally accepted that early detection of cancer is essential even before anatomic anomalies are visible. A major challenge in cancer diagnosis in the 21st century is to be able to determine the exact relationship between cancer biomarkers and the clinical pathology, as well as, to be able to non-invasively detect tumors at an early stage for maximum therapeutic benefit. In cancer therapy, targeting and localized delivery are the key challenges. To wage an effective war against cancer, we have to have the ability to selectively attack the cancer cells, while saving the normal tissue from excessive burdens of drug toxicity. In this presentation, we will discuss the different nanotechnology platforms that are used for early detection and diagnosis of cancer, molecular imaging, and targeted drug delivery systems. Special emphasis will be placed on nanoplatforms that offer opportunities for multi-functionalization for simultaneous imaging and therapy.
