AMS of heavy elements with an ECR ion source and the ATLAS linear accelerator.
Understanding the fate of heavy-metal contaminants in the environment is of fundamental importance in the development and evaluation of effective remediation and sequestration strategies. Among the factors influencing the transport of these contaminants are their chemical speciation and the chemical and physical attributes of the surrounding medium. Bacteria and the extracellular material associated with them are thought to play a key role in determining a contaminant's speciation and thus its mobility in the environment. In addition, the microenvironment at and adjacent to actively metabolizing cell surfaces can be significantly different from the bulk environment. Thus, the spatial distribution and chemical speciation of contaminants and elements that are key to biological processes must be characterized at micron and submicron resolution in order to understand the microscopic physical, geological, chemical, and biological interfaces that determine a contaminant's macroscopic fate. Hard x-ray microimaging is a powerful technique for the element-specific investigation of complex environmental samples at the needed micron and submicron resolution. An important advantage of this technique results from the large penetration depth of hard X-rays in water. This advantage minimizes the requirements for sample preparation and allows the detailed study of hydrated samples. This paper presents results of studies of the …

Analysis of the pore structure of activated carbons produced from paper mill sludge using small angle neutron scattering data
A novel, cost-effective, and environmentally benign process was developed to produce highly efficient carbon-based adsorbents (CBAs) from paper mill sludge. The production process required chemical activation of sludge using zinc chloride and pyrolysis at 750 C in N{sub 2} gas. The produced CBAs were characterized according to their surface area and pore size distribution using N{sub 2}-BET adsorption isotherm data. Further characterization of the surface and pore structure was conducted using a unified exponential/power law approach applied to small angle neutron scattering (SANS) data. The structural features analyzed by SANS revealed the dependence of porosity with zinc chloride concentration. The presence of inaccessible pores was also determined by contrast-match experiments.

B-Physics prospects at CDF
Between 1992 to 1996, the CDF experiment has collected a data sample of 110 pb{sup -1} of p{bar p} collisions at {radical}s = 1.8 TeV at the Fermilab Tevatron. In the year 2001 the Tevatron will commence p{bar p} collisions again at {radical}s = 2.0 TeV delivering an integrated luminosity of 1 fb{sup -1} per year. In the mean time the CDF detector will have undergone substantial upgrades which will allow for a rich B physics program with unique capabilities. In this paper we discuss the B physics prospects at CDF with the data that will be collected during this upcoming Tevatron run.

The crystallization of hectorite clays as monitored by small angle X-ray scattering and NMR
The authors have probed the 48-hr crystallization of a magnesium silicate clay called hectorite. Small angle X-ray scattering (SAXS) at the Advanced Photon Source using aliquots ex situ has revealed that data is consistent with ex situ XRD, TGA, AFM, and IR data in that all these techniques see clay crystallite beginning to form in the first few hours of reaction. Tetraethylammonium (TEA) ions are used to aid crystallization and become incorporated as the exchange cations within the interlayers. {sup 13}C NMR shows that 80% of the final TEA loading is accomplished in the first 10 hrs. {sup 29}Si NMR displays a visible clay silicate peak after just 1 hr. In addition, the first in situ study of clay crystallization of any kind was performed by in situ SAXS. Results are consistent with the ex situ data as well as showing the sensitivity of SAXS to sol gel reactions occurring on the order of minutes.

Defense Cleanup and Environmental Programs: Authorization and Appropriations for FY2000
Although Congress authorizes most federal programs for multiple years, it annually authorizes programs for national defense as well as appropriating funding for them each fiscal year. Of the activities traditionally authorized and funded, the Department of Defense (DOD) administers the following six environmental programs: environmental restoration, compliance, cleanup at base closure sites, pollution prevention, environmental technology, and natural resource conservation.

Detection of linear features using a localized radon transform with a wavelet filter
One problem of interest to the oceanic engineering community is the detection and enhancement of internal wakes in open water synthetic aperture radar (SAR) images. Internal wakes, which occur when a ship travels in a stratified medium, have a V shape extending from the ship, and a chirp-like feature across each arm. The Radon transform has been applied to the detection and the enhancement problems in internal wake images to account for the linear features while the wavelet transform has been applied to the enhancement problem in internal wake images to account for the chirp-like features. In this paper, a new transform, a localized Radon transform with a wavelet filter (LRTWF), is developed which accounts for both the linear and the chirp-like features of the internal wake. This transform is then incorporated into optimal and sub-optimal detection schemes for images (with these features) which are contaminated by additive Gaussian noise.

Growth of homo-epitaxial silicon at low temperatures using hot wire chemical vapor deposition
The authors report on the first known growth of high-quality epitaxial Si via the hot wire chemical vapor deposition (HWCVD) method. This method yields device-quality epitaxial Si at the comparatively low temperatures of 195 to 450 C, and relatively high growth rates of 3 to 20 {angstrom}/sec. Layers up to 4,500-{angstrom} thick have been grown. These epitaxial layers have been characterized by transmission electron microscopy (TEM), indicating large regions of nearly perfect atomic registration. Electron channeling patterns (ECPs) generated on a scanning electron microscope (SEM) have been used to characterize as well as optimize the growth process. Electron beam induced current (EBIC) characterization has also been performed, indicating defect densities as low as 5 x 104/cm{sup 2}. Secondary ion beam mass spectrometry (SIMS) data shows that these layers have reasonable impurity levels within the constraints of the current deposition system. Both n and p-type layers were grown, and p/n diodes have been fabricated.

In situ study of dislocation behavior in columnar Al thin film on Si substrate during thermal cycling
In situ transmission electron microscopy (150 kV) has been employed to study the evolution of dislocation microstructure during relatively rapid thermal cycling of a 200 nm Al thin film on Si substrate. After a few thermal cycles between 150 and 500 C, nearly stable Al columnar grain structure is established with average grain less than a {micro}m. On rapid cooling (3--30+ C/s) from 500 C, dislocations first appear at a nominal temperature of 360--380 C, quickly multiplying and forming planar glide plane arrays on further cooling. From a large number of such experiments the authors have attempted to deduce the dislocation evolution during thermal cycling in these polycrystalline Al films and to account qualitatively for the results on a simple dislocation model.

Multiyear Program Plan: Reducing Friction and Wear in Heavy Vehicles
As described in its multiyear program plan for 1998-2000, the Office of Heavy Vehicle Technologies (OHVT) envisions the development of a fuel-flexible, energy-efficient, near-zero-emissions, heavy-duty U.S. diesel engine technology devolving into all truck classes as a real and viable strategy for reducing energy requirements for commercial transport services and the rapidly growing multipurpose vehicle market (pickups, vans, and sport utility vehicles). Implementation of the OHVT program plan will have significant national benefits in energy savings, cleaner air, more jobs, and increased gross domestic product (GDP). Successful implementation will reduce the petroleum consumption of Class 1-8 trucks by 1.4 million barrels of oil per day by 2020 and over 1.8 million by 2030, amounting to a reduction in highway petroleum consumption of 13.2% and 18.6%, respectively. All types of regulated emissions will be reduced, that is, 20% drop in PM10 emissions (41,000 metric tons per year) by 203 0, 17% reduction in CO2 greenhouse gases (205 million metric tons per year), 7% reduction in NOx, 20% reduction in NMHC, and 30% reduction in CO. An increase of 15,000 jobs by 2020 is expected, as is an increase of $24 billion in GDP. The strategy of OHVT is to focus primarily on …
