The final prototype of the Microcircuit Board Repair apparatus will be capable of laying down or lifting metal strips with micrometer dimensions. Under real time computer control, the translation stages will be fully automated or manually controlled. The end user will monitor the process in real time using a camera attached with the source. Laying down the metal lines will be done using Laser C ...

This Phase I project involves the development of a portable system for the analysis of trace metals in aqueous solutions based on an innovative disposable multi-element nanoband electrode sensor. The system will be capable of real-time detection of a variety of heavy metals in aqueous solutions, including Zn, Cd, Pb, Cr, Cu, and Hg with a 100 ppb detection limit. The system also will be capable ...

WASTE PICKLING LIQUOR IS PRODUCED WHIN ACID IS USED TO RE- MOVED SCALE FROM STEEL PRODUCTS. TYPICALLY IT CONTAINS 10% ACID AND 5% IRON IN THE FORM OF THE FERROUS SALT OF THE ACIDUSED. IT IS PRODUCED IN LARGE QUANTITIES. ITS DISPOSAL IS DIFFICULT AND WILL BECOME MORE SO WHEN THE PLANNED TOTAL BANON ON DEPOSITION OF LIQUIDS IN A LAND DISPOSAL SITES BECOMES EFFECTIVE. AN ELECTROLYTIC PROCESS WILL BE ...

THE CONTAINMENT OF TOXIC MATERIALS ALREADY BURIED IN THE GROUND AND THE CONSTRUCTION OF NEW DISPOSAL SITES ARE DIFFI-CULT TASKS. IN BOTH CASES THERE IS A NEED FOR VERTICAL AND HORIZONTAL BARRIER WALLS IN THE GROUND THAT ARE KNOWN TO BE DIFFICULT AND EXPENSIVE TO CONSTRUCT WITH CURRENTLY-AVAILA- BLE TECHNOLOGIES. FLUIDYNE PROPOSES TO CONSTRUCT SUCH BARRIER WALLS WITH A NOVEL ONE-STEP PROCESS THT IN ...

TRICHLOROETHYLENE (TCE) IS A WIDESPREAD POLLUTANT AND IS REPORTED TO BE THE MOST FREQUENTLY ENCOUNTERED CONTAMINANT AT HAZARDOUS WASTE SITES. ALL PREVIOUS ATTEMPTS AT IN SITU BIOREMEDIATION HAVE USED A PROCESS WHERE METHANTROPHIC BACTERIA WERE STIMULATED BY THE SUBSURFACE DELIVERY OF AIR AND METHANE RESULTING IN A "FORTUITOUS" COMETABOLISM OF TCE. THIS PROCESS AT ONE TIME APPEARED PROMISING FOR TH ...

Breathable release coatings that can withstand processing conditions up to 750F are needed for use on ceramic tooling. In situ removal of volatiles in solvent-based composite processing is a critical issue that will enable production of high quality parts at lower cost per part. Current release coatings meet neither the temperature nor the solvent transport requirements of solvent-based composit ...

A number of industrial processes generate wastewater with mercury contamination. Existing cleanup processes have difficulties in achieving low mercury discharge limits, especially in the presence of competing metal ions already below their discharge limits. Commercial ion exchange media are not selective for mercury, so other metal ions compete with mercury for binding sites. Consequently, excess ...
