Description: One of the leading problems that will be carried into the 21st century is that of alternative fuels to get our planet away from the consumption of fossil fuels. There has been a growing interest in the use of nanotechnology to somehow aid in this progression. There are several unanswered questions in how to do this. It is known that carbon nanotubes will store hydrogen but it is unclear how to increase that storage capacity and how to remove this hydrogen fuel once stored. This document offers some answers to these questions. It is possible to implant more hydrogen in a nanotube sample using a technique of ion implantation at energy levels ~50keV and below. This, accompanied with the rapid removal of that stored hydrogen through the application of a microwave field, proves to be one promising avenue to solve these two unanswered questions.

Nanotechnology: Better Guidance Is Needed to Ensure Accurate Reporting of Federal Research Focused on Environmental, Health, and Safety Risks

Nanotechnology: Better Guidance Is Needed to Ensure Accurate Reporting of Federal Research Focused on Environmental, Health, and Safety Risks

Date: March 31, 2008
Creator: United States. Government Accountability Office.
Description: A letter report issued by the Government Accountability Office with an abstract that begins "The National Nanotechnology Initiative (NNI), administered by the Office of Science and Technology Policy (OSTP), is a multiagency effort intended to coordinate the nanotechnology-related activities of 25 federal agencies that fund nanoscale research or have a stake in the results. Nanotechnology is the ability to control matter at the scale of a nanometer--one billionth of a meter. A key research area funded by some federal agencies relates to potential environmental, health, and safety (EHS) risks that may result from exposure to nanoscale materials. Because of concerns about federal efforts to fund and prioritize EHS research, GAO was asked to determine (1) the extent to which selected agencies conducted such research in fiscal year 2006; (2) the reasonableness of the agencies' and the NNI's processes to identify and prioritize such federal research; and (3) the effectiveness of the agencies' and the NNI's process to coordinate this research. GAO reviewed quantitative and qualitative data from five federal agencies that provided 96 percent of fiscal year 2006 funding for EHS research."
