NASA Scientific and Technical Aerospace Reports

considers the environment of the whole earth, metrics for estimating environmental effects such as CO2 reduction in NTT, and
products that create a good life and a safe and secure society. Since one major problem is the huge amount of electrical power
consumed by advanced IP (Internet protocol) technology, we are developing clean energy technology, EMC (electromagnetic
compatibility) technology for evaluating the influence of electro- magnetic radiation and interference between communication
equipment, and a backup power technology for supplying continuous 48 V DC based on large- capacity nickel metal hydride
(NiMH) batteries. In addition. we are developing micro-energy technology that enables ubiquitous communication to give
people a good life. such as the photovoltaic generator called ‘pocket energy’ that was commercialized by NTT-AT Corporation
in July. In studying environment issues, we believe that we must understand the present condition of the environment.
disseminate this information to everyone, and provide information that matches the needs of individuals. For these purposes,
we are developing technologies that supply environmental network services using sensors and IP networks. such as a
networked pollen sensing system and a networked multi-sensing air environment monitoring system that can measure
suspended particulate matter, nitrogen dioxide, and ozone. We are also developing system solutions such as disaster
surveillance systems, food traceability systems, and systems for evaluating the effects of recycling in agriculture.

The project emphasizes NASA’s Missions of understanding and protecting our home planet as well as of inspiring the
next generation of explorers. The project fellow worked as part of a team on the development of new emulsion-based
technologies for the removal of Contaminants from soil, sediment, and groundwater media with the scientists in charge of the
emulsion-based technologies. Hands-on chemistry formulation and analyses using a GCM, as well as field sampling was done.
The fellow was tidy immersed in lab and fieldwork, as well as, training sessions to qualify her to do the required work. The
principal outcome of the project is the motivation to create collaboration links between major research university (UCF) and
an emerging research university (UT).

The remediation of polychlorinated biphenyls (PCBs) and other chlorinated synthetic aromatic compounds are of great
concern due to their toxicity and persistence in the environment. When released into the environment, PCBs are sorbed to
particulate matter that can then disperse over large areas. Although the US Environmental Protection Agency (EPA) has
banned the manufacture of PCBs since 1979, they are still present in the environment posing possible adverse health affects
to both humans and animals. Thus, it is of utmost importance to develop a method that remediates PCB-contaminated soil,
sediments, and water. The objective of our research was to develop an in-situ PCB remediation technique that is applicable
for the treatment of soils and sediments. Previous research conducted at the University of Central Florida (UCF) proved the
feasibility of using an emulsified system to dehalogenate a dense non-aqueous phase liquid (DNAPL) source, such as TCE,
in the subsurface by means of an in-situ injection. The generation of a hydrophobic emulsion system drew the DNAPL TCE,
through the oil membrane where it diffused to the iron particle and underwent degradation. TCE continued to enter, diffuse,
degrade and exit the droplet maintaining a concentration gradient across the membrane, thus maintaining the driving force of
the reaction.
