An overview of nanotechnology in the world of information technology
Applications of nanomaterials
Robert M. His research interests are in the surface science of nanoparticles for sensing applications, and in the study of environmental risks from nanoparticles using scenario analysis within a regulatory structure. Important nanotechnology achievements seem to be announced almost daily. Reid Lifset Dr. Improved vehicle fuel efficiency and corrosion resistance by building vehicle parts from nanocomposite materials that are lighter, stronger, and more chemically resistant than metal. Researchers have developed a nanofabric "paper towel" woven from tiny wires of potassium manganese oxide that can absorb 20 times its weight in oil for cleanup applications. Nanotechnology is being studied for both the diagnosis and treatment of atherosclerosis, or the buildup of plaque in arteries. In the closing discussion, participants noted that technology appears to be on the verge of altering the entire context of environmental protection and social welfare. Granger Morgan, Chair of the SAB, noted that the topics and recommendations emerging from the workshop were diverse. Nanoparticles are used increasingly in catalysis to boost chemical reactions.
Water filters that are only nanometers wide can remove nano-sized particles, including virtually all viruses and bacteria.
Thanks to nanotechnology, a huge variety of chemical sensors can be programmed to detect a particular chemical at amazingly low levels, for example, a single molecule out of billions.
What science and research and environmental policy issues need to be addressed to confront these challenges effectively? She worked for 5 years in private industry with an environmental engineering consulting firm in Florida primarily in the area of drinking water treatment.
Monbouquette 9 focused on several applications in his area of expertise. Nanofilters remove nearly all airborne particles from the air before it reaches the combustion chamber, further improving gas mileage.
They are also working to identify compositionally similar cis- regulatory element clusters in groups of co-regulated genes, which may serve as valuable probes for genome-wide identification of regulatory regions. This process would cost less than methods that require pumping the water out of the ground for treatment.
Advantages of nanomaterials
Otto has almost 20 years of experience in hazardous waste site evaluation and remediation and environmental regulation and policy development. Alexander specialized in news media relations consulting and writing on alternative energy and environmental issues. He also managed projects in ecosystem valuation and edited a special issue of the Journal of Ecological Economics He also led EPA training courses in environmental policy and risk assessment, in Eastern Europe. The following points were prepared for the plenary discussion. He has also addressed the structure and function of aquatic microbial food webs in Alaskan arctic lakes, and how genetic variability in Alaskan fish populations relates to landscape features. He received a Ph. He stated that the ideas discussed at this workshop will set the stage for additional SAB deliberations regarding how to best advise the Agency on the use of new technologies in its science enterprise. Nano-engineering of aluminum, steel, asphalt, concrete and other cementitious materials, and their recycled forms offers great promise in terms of improving the performance, resiliency, and longevity of highway and transportation infrastructure components while reducing their life cycle cost. The Computational Energy Science work entails the development of science-based models of fossil fuel conversion phenomenon, simulation capabilities that couple unit processes in advanced power generation technologies, and virtual power plant simulations. Environmental Remediation In addition to the ways that nanotechnology can help improve energy efficiency see the section above , there are also many ways that it can help detect and clean up environmental contaminants: Nanotechnology could help meet the need for affordable, clean drinking water through rapid, low-cost detection and treatment of impurities in water. Nanotechnology is being studied for both the diagnosis and treatment of atherosclerosis, or the buildup of plaque in arteries. Nanotechnology researchers are working on a number of different therapeutics where a nanoparticle can encapsulate or otherwise help to deliver medication directly to cancer cells and minimize the risk of damage to healthy tissue.
On the Horizon These are just a few of the thousands of ways that nanotechnology impacts society. Bob Twiss Dr.
Industrial ecology can guide holistic thinking about environmental problems. Later, as an independent writer and producer, Ms.
Nano engineered materials
Spatial cognition through wearable sensors and computers to enhance awareness of health, environment, potential hazards, natural resources, etc. Deborah Estrin Dr. Meryl Karol Dr. It includes gene regulation, mRNA expression, and cell-type specificity. The primary objective of this workshop was to educate and inform the SAB, and to initiate a dialogue on the implications of these technologies for science and research advice to the EPA. Such advancements offer substantial opportunities and challenges for EPA science and research planning and implementation and are provided in subsequent sections of this report. Many drink bottles are made from plastics containing nanoclays, which increase resistance to permeation by oxygen, carbon dioxide, and moisture. Technology causes fundamental changes, and the rate of change currently exceeds the ability of governments to react in a timely manner. Biotechnolgy - Genomics Invited Speaker Dr. Deborah Swackhamer Dr. Nanotechnology is also being applied to oil and gas extraction through, for example, the use of nanotechnology-enabled gas lift valves in offshore operations or the use of nanoparticles to detect microscopic down-well oil pipeline fractures.
