Chemiresistors are an important class of electronic sensors that detect the presence of analytes/chemicals via a change in the resistance of a sensor element. A typical interdigitated electrode array is deposited onto an insulating substrate with metallic electrodes that have feature sizes in the 5-500 m range. The metal electrodes are typically sputter coated onto the substrate, using lithogra ...

There is a critical need for DoD to develop power sources that will increase the mission lifetime for unattended sensors and sensor radio networks. In order to take advantage of recent advances in extremely low power subthreshold circuits to greatly exte...

Compact Membrane Systems (CMS) proposes to employ membrane systems for pressure-driven separation of water from black liquor to replace the first two stages of existing multiple-effect evaporators. This is a promising approach to considerably reduce the steam energy required for concentration. Membrane materials must withstand high temperature, high salinity and high pH conditions. Fouling of the ...

"Reliable and sensitive detection of microbial biowarfare agents (BWAs) such as Bacillus anthracis, Yersinia pestis, and Francisella tularensis is an important challenge for both military operations and domestic anti-terrorism efforts. We are proposing todevelop an antibody functionalized biomimetic polymer coating for filter membranes that will become fluorescent when exposed to samples containi ...

"Reliable and sensitive detection of potential biowarfare agent (BWA) toxins such as botulinum toxin, staphylococcal enterotoxin, saxitoxin, etc., is an important challenge during both military operations and for domestic anti-terrorism efforts. We proposeto develop biomimetic polymerized liposomes/antibody conjugates that will detect toxins in aqueous samples, and will be integrated into a porta ...

Concentration of fruit juices is a valuable unit operation. The current preferred method of juice concentration is triple effect evaporation. This technique cannot concentrate to high (75%) solids content without (1) developing a burnt taste to the sugar content and (2) driving off the low molecular weight hydrocarbons that provide most of the flavor and aroma difference between fresh and frozen c ...

There is a recognized need for more effective and economical treatment processes for oily bilge waters. Direct filtration through currently available ultrafiltration (UF) membranes is a mechanically simple process that can provide excellent effluent quality. A limitation to more extensive use of this technology is the tendency of the hydrophilic membranes currently used to foul in the presence of ...

Fugitive emissions of volatile organic compounds (VOCs) from gasoline marketing facilities continues to be an energy, safety, and environmental issue. Beginning in model year 2000, all vehicles are required to have an onboard refueling vapor recovery (ORVR) system, which will increase fugitive emissions from refueling stations because of the interface between ORVR vehicles and gasoline station und ...

Volatile organic compounds (VOCs) continue to be major air pollutants. Existing technologies (e.g., thermal oxidation, catalytic oxidation) are costly processes that limit their commercial viability. Compact Membrane Systems, Inc. (CMS) proposes a novel enhanced VOC oxidation process. CMS' novel oxidation technique should require less maintenance, consume less fuel, and reduce NOx emissions compar ...
