Previously Funded Projects

Bioengineering

Micropatterned Schwann Cell-Seeded Guidance Conduits for Nerve Regeneration
Improvements in the techniques of nerve repair could provide better return of protective sensibility and tactile discrimination, reduce denervation atrophy of muscles, and minimize pain syndromes. Achieving full organ function after peripheral nerve injury is the ultimate goal.


New Cleanup Approaches

Expedited Site Characterization
Remediation of DOE sites should be quicker and less costly once a streamlined, cost-effective characterization approach is in place.


Analyzing Environmental Contaminants

Improvements in Inductively Coupled Plasma - Mass Spectrometry
Augmenting an already effective analytical technique, sampling improvements for ICP-MS promise reduced hazards, costs and complexity for assessing DOE's radioactive sites.

Electrospray Mass Spectrometry
Adapting for environmental use an analytical technology already common in medical applications, researchers are developing a single instrument comprehensive enough for a wide range of environmental analyses. Reducing the need for multiple analytical tools, this system should cut the costs and complexity of DOE's environmental assessments.

LA-ICP-AES using a high resolution fiber optic interferometer
With a remarkable combination of small size, affordability and high sensitivity, Ames Lab's new interferometric ICP-AES spectrometer should make detailed field-testing possible in areas where traditional methods lack the required selectivity and portability.

FTIR-Photoacoustic spectroscopy of solids
This technique reduces worker exposure to radiation because of the small sample size and the dramatic reduction in sample preparation needed, also making the technique faster and more cost-effective.


Monitoring Environmental Contaminants

Zero Tension Lysimeters
Offering expanded monitoring capabilities at a reduced cost, this new zero-tension lysimeter produces a more complete and accurate picture of soil and water flow to help guard against the spread of contaminants in upper regions of the soil.

Ultrasonic Characterization of Wastes
Safe, quick and cost-effective physical description of stored waste will help speed the decommissioning of storage tanks for newer, more effective waste treatment, storage and disposal.

Measurements by Transient Infrared Spectroscopies (TIRS)
Helping DOE improve waste solidification with continuous monitoring, Ames Lab's new infrared spectrometry technique will allow process operators to maximize and document the quality of polymer-encapsulated waste for safer, more efficient storage and disposal.


Decontaminating Environmental Wastes

Laser Decontamination of Metals
This new technique that uses lasers for safe and effective metal decontamination produces little secondary waste and can reduce selected waste volumes (or at least lower waste classifications) and therefore reduce the hazards and costs of waste storage and disposal.

X-ray Detector System Helps Evaluate Facility Contamination
Rapidly providing critical contaminant information on site, Ames Lab's portable K-edge heavy metal detector should make the dismantling of DOE's contaminated facilities easier, safer and more efficient.


Environmentally Conscious Manufacturing

Lead-free Solder Paste
The strength, heat resistance, workability and cost-effectiveness of Ames Lab's new lead-free solder make it an attractive alternative for getting environmentally hazardous lead out of commonly used solders.
