New Access Control Technologies: Biometric Identification, Purdue Ect Team
ECT Fact Sheets Archive
Biometrics are computerized methods of recognizing people based on physical or behavioral characteristics. The main biometric technologies include face recognition, fingerprint, hand geometry, iris, palm prints, signature and voice.

Dma™: Digestion Material For Asbestos, Purdue Ect Team
Dma™: Digestion Material For Asbestos, Purdue Ect Team
ECT Fact Sheets Archive
Current techniques for removing asbestos- containing fireproofing require the construction of air-tight barriers, labor- intensive scraping of the fireproofing, and the installation of new asbestos-free fireproofing. The DMATM product is the result of a joint development by W.R. Grace & Co. and Department of Energy's Brookhaven National Laboratory. The new technology uses a foamy solution sprayed directly onto asbestos-containing fireproofing. After absorbing into the fireproofing, the foam chemically digests asbestos fibers and dissolves them into harmless minerals. The process is the first to chemically destroy asbestos without first removing the fireproofing.
