2:00 PM - ELECTRON AND OPTICAL PHYSICS DIVISION SEMINAR: Low Energy Lepton Interactions: Electron- and Positron-Driven Processes and Their Applications
Low energy (0-100 eV) interactions between electrons/positrons and atoms, molecules and materials underpin a large and increasing number of technological, environmental and biomedical applications. For example, both electron and positron interactions with biologically relevant molecules are emerging as important mechanisms in fields such as radiation damage and Positron Emission Tomography. An essential aspect of the characterisation of such interactions is the ability to provide accurate, absolute collision rates and cross sections and, in many cases, these are likely to come from theory, once it has been benchmarked against experiment for a number of test cases. This talk will attempt to illustrate the current state of the art in the field and touch upon both realised, and potential, applications.

10:00 AM - CERAMICS DIVISION SEMINAR: High Temperature Ceramic Composites for Aerospace
The use of textile methods to optimize fiber architecture in ceramic composites has provided new opportunities for the design of aerospace structures and propulsion systems that require lightweight, strong, high temperature materials. The selection of materials for such structures will be discussed, along with material developments for application in turbine engine combustors, rocket engines and combined cycle engines. Material limitations and degradation mechanisms will also be discussed along with some challenges in simulating aggressive combustion environments in laboratory scale experiments.

10:30 AM - ATOMIC PHYSICS DIVISION SEMINAR: Highlights in Quantum-Atom Optics in Australia
The ARC Centre for quantum-atom optics (ACQAO) combines the talent and resources of several teams across Australia. Recently we have made good progress with our experiments and theory in both the generation and use of laser beams with strong nonclassical properties and the control of matter waves, such as atom lasers. This talk will summarize some of the new results . Particular emphasis will be given to experiments on spatial multimode fields which allow novel tests of quantum mechanics as well as technology for spatial sensing and spatial quantum encoding beyond the conventional quantum noise limit.

10:30 AM - PHYSICS LABORATORY SEMINAR: From the Andes to Antarctica: Unlocking the Secrets of Climate Change
Taking us from 20-foot-deep ice pits at the South Pole to the dense rainforests in South America, the presentation reviews fascinating discoveries that have helped us better understand climate change, the origin of the solar system, acid rain and the accumulation of greenhouse gases. Thiemens will describe the quantifiable scientific evidence driving the green movement and how these findings can be effectively used in our everyday lives.

10/12/07 1:00 PM - NIST COLLOQUIUM SERIES : This is Your Brain on Music
NOTE: DIFFERENT TIME (VTC from Boulder) What do we know about music and the brain? Are the brains of musicians different from the brains of non-musicians? Why do some people become experts and others -- with the same amount of practice -- do not? Why do we like the music we like? What are the neural similarities between language and music? By the age of 5 we have all learned, implicitly, the rules of what notes go together and which don’t. How is the brain able to do this? How does music affect our emotions? Music triggers the reward centers in our brains so that we are hardwired for music. Is music more fundamental to our species than language?

10/18/07 10:30 AM - NIST CENTER FOR NEUTRON RESEARCH SEMINAR: Sigma Xi Colloquium Series
The Retired Scientists, Engineers and Technicians (ReSET) program was established in 1988 with the object of using the underused resource of retired scientists and engineers, to fulfill a need in elementary schools. That need was assessed to be a more lively and interesting introduction of science to young children. The program was designed for senior scientists who had not taught school before or even been in an elementary school for over 50 years.. Volunteers work as a team with the classroom teachers to do hands-on or demonstration experiments with the children. Volunteers use their professional backgrounds to spark enthusiasm for science. Thus the program contributes to the future of science literacy in the United States.

10/26/07 1:30 PM - CENTER FOR NANOSCALE SCIENCE AND TECHNOLOGY SEMINAR: Biological macromolecules as scaffolding for precisely engineered nanostructures
We are currently developing a system for using biological macromolecules as scaffolding for the construction of nanostructures comprising multiple inorganic nanoparticles. The system utilizes the geometry of the macromolecules to define the three-dimensional arrangement of inorganic particles in the structure. A massively parallel assembly process will be used to provide for the mass production of identical nanostructures. We envision applications to include, for example, (i) construction of small assemblies of metallic nanoparticles to form nanolenses capable of focusing surface plasmons and (ii) the construction of magnetic cellular automata.
