According to forum participants, nanomanufacturing is an emerging megatrend that will bring diverse societal benefits and new opportunities--potentially creating jobs through disruptive innovation. Further, nanomanufacturing has characteristics of a general purpose technology (GPT)--such as electricity or computers, or historically, innovations such as the smelting of ore and the internal combustion engine. As one participant said: "Everything will become nano." Figure 1, below, provides examples of nanomanufacturing products that illustrate four diverse areas being affected by nanomanufacturing. Different manufacturing activities occur at different stages of the value chain. According to experts, the United States likely leads in nanotechnology R&D today but faces global-scale competition--which one forum participant described as a "moon race." Two indicators of how the U.S. compares with other countries are R&D funding levels and scientific publications. With respect to R&D funding, there is some uncertainty about international comparisons because relevant definitions may vary across nations--and some countries may not adequately or effectively track R&D investments or not share such information externally. However, forum participants viewed the United States as currently appearing to lead in terms of overall (that is, combined public and private) funding of nanotechnology R&D. When public funding alone was considered, a participant in the July 2013 forum presented projections showing the United States as likely being surpassed by some other nations. With respect to scientific publications, the United States appears to dominate in numbers of nanotechnology publications in three highly cited journals--which is an apparent indication of U.S. competitiveness in quality research. However, China overtook the United States in 2010 through 2012 (the most recent year reported) in terms of the quantity of nano-science articles published annually. A semiconductor is the generic term for the various devices and integrated circuits that regulate and provide a path for electrical signals. As such, semiconductors are the foundation of the electronics industry. semiconductors. However, they also said that U.S. manufacturing in this area has declined (although some plants are located here) and that the United States does not have a strategy to assure U.S. leadership in the semiconductor industry. Nano-based concrete: Concrete is the most heavily used construction material in the world--with about 5-billion cubic yards annually produced worldwide--and demand for it is expected to increase to meet the infrastructure needs of a growing global population. Nanomaterials can enhance the performance of the concrete used to construct this infrastructure. These materials might potentially result in roads, bridges, buildings, and structures that are more easily built, longer-lasting, and better-functioning than those that currently exist. Experts offered differing views on U.S. global competitiveness in the commercialization and use of nanomaterials in concrete. A key forum participant said that while cement for domestic use is produced in the United States, today's dominant companies-- which are spearheading development of new technologies--are headquartered elsewhere (although this industry was previously dominated by the United States). Additionally, some experts said that other countries are spending more resources than the United States to promote commercialization; for example, one expert said that China established a national technology center to improve its competitiveness and domestic production of high-value, nano-based construction products. On the positive side, chemical admixtures are one means to introduce nano-materials into concrete--and the United States has a 15% market share of chemical sales, worldwide. According to forum participants and experts interviewed, challenges to U.S. competitiveness in nanomanufacturing include U.S. funding gaps, significant global competition, and lack of a U.S. vision for nanomanufacturing, among others. Participants said that in the United States, government often funds research or the initial stages of development, whereas industry typically invests in the final stages. As a result, U.S. innovators may find it difficult to obtain either public funding or private investment during the middle stages of innovation. For nano-innovators, this support gap can characterize the middle stages of both (1) efforts to develop a new technology or product, and/or (2) efforts to develop a new manufacturing process. Thus, U.S. innovators may encounter two support gaps, which participants termed: the Valley of Death (the lack of funding or investment for the middle stages of developing a technology or product), and the Missing Middle (a similar lack of adequate support for the middle stages of developing a process or an approach to manufacture the new product at scale). The Valley of Death begins after a new technology or product has been validated in a laboratory environment and continues through testing and demonstration as a prototype in a non-laboratory environment (but before industry acquires it as a commercial technology or product). The Missing Middle occurs during analogous stages of the manufacturing-innovation process, as illustrated below (fig.2). Participants further said that substantial amounts of funding/investment are needed to bridge the Valley of Death and the Missing Middle--and that high costs can be a barrier to commercialization, especially for small and medium-sized U.S. enterprises. Additionally, some said that recently, venture capital (VC) funding has been diverted from physical science areas like nanotechnology to fund new ventures in Internet services that may provide larger and faster returns on investment. Varied forum participants and experts interviewed made statements to the effect that other nations do more than the United States in terms of government investment in technology beyond the research stage. According to participants, the funding and investment gaps that hamper U.S. nano-innovation (such as the Missing Middle) do not apply to the same extent in some other countries--for example, China and Russia--or are being addressed. Multiple participants referred to the European Commission's upcoming Horizon 2020 program, specifically mentioning a key program within Horizon 2020: the European Institute of Innovation and Technology or EIT, which emphasizes the nexus of business, research, and higher education. The 2014-2020 budget for the EIT portion of this European Commission initiative is EUR2.7 billion (or close to $3.7 billion in U.S. dollars as of January 2014). Multiple forum participants said that the United States lacks a vision or However, one explained strategy for a nanomanufacturing capability.that such a strategy could be designed by (1) proceeding from a vision or goal to the examination of the social, technological, economic, environmental, and political elements of the relevant systems and their interactions with one another; (2) understanding the basic science, engineering, and manufacturing involved; and (3) consulting the full range of stakeholders. This participant said that although systems thinking and the design of a grand strategy, based on a vision, are often employed following a crisis that motivates a nation, such an effort could be usefully pursued in advance of a crisis, using foresight. Such an effort would reflect the statements of another participant who said, in effect, that the future of nanomanufacturing for the United States is limited only by our ability to envision what we want to see realized. This approach would likely draw upon the U.S. federal government to develop and articulate the strategy--in coordination with industry, academia, nonprofits, and state and local governments. Additionally, some federal effort is implied for implementation, but the level of funding and the mix of funding sources (not specifically discussed at the forum) would likely be specified as part of developing a vision and strategy for nanomanufacturing. Forum participants described further challenges to U.S. competitiveness in nanomanufacturing, including the earlier loss of an industry, as discussed above for lithium-ion batteries--or even extensive prior offshoring in some industries, which can be important, in part because, as one participant said: "when we design here ship abroad, we lose this shop- floor-innovation kind of mentality" and threats to U.S. intellectual property on the part of some other countries or entities within those countries--which occur with respect to both university research and private R&D on, for example, manufacturing processes. Forum participants suggested the need to address policy issues in U.S. research funding, challenges to U.S. competitiveness in nanomanufacturing, and other areas, including environmental, health, and safety (EHS) issues. U.S. research funding. Forum participants said it is essential for the United States to maintain a high level of investment in fundamental nanotechnology research. This is because (1) some other countries are now making significant investments in R&D and (2) ongoing research breakthroughs will drive the future of nanomanufacturing. One participant emphasized that as nanotechnology increasingly moves into manufacturing, it may be important to consider not only continuing funding for fundamental nanotechnology research, but also targeting some funding to early stage research on nanomanufacturing processes. Challenges to U.S. competitiveness in nanomanufacturing. Forum participants said the United States could improve U.S. competitiveness in nanomanufacturing by pursuing one or more of three approaches, which might be viewed either as alternatives or as complementary approaches. These three approaches are described in table 1, below. Two examples of U.S. public-private partnerships that are designed to promote innovation in nanomanufacturing are housed in universities. A related example with similar goals is a user facility that is located within a federal laboratory. The Center for Nanomanufacturing Systems for Mobile Computing and Mobile Energy Technologies (NASCENT) was founded at the University of Texas at Austin in 2012, with funding from NSF. Two key objectives are: to create processes and tools for manufacturing nano-enabled components for mobile computing, energy, healthcare, and security-- as well as simulations for testing potential nanomanufacturing approaches, and to provide an ecosystem with computational and manufacturing facilities--for example, large-area wafer-scale and roll-to-roll nanomanufacturing,faculty, staff, and students. as well as the university's resources, including The Center's overall goal is to facilitate the rapid creation and deployment of new products and to mitigate the risks associated with the Valley of Death and the Missing Middle. A co-director of NASCENT told us that another goal is to use "10 years of NSF funding to develop the center infrastructure so it will . . . self-supported from industrial partnerships and other funding sources." Center partners include industrial partners--such as toolmakers, materials suppliers, and device makers--that will provide both technical and financial support; companies ranging from start-ups to well-established firms that will implement or adopt technology created by the center; and "translational research partners" such as technology incubators and technology funds. The College of Nanoscale Science and Engineering (CNSE), established in 2004, is part of the State University of New York and is located in Albany--within the existing regional (Hudson Valley) ecosystem centered on the semiconductor industry. CNSE is designed as a unique research, development, prototyping, and educational public-private partnership for advancing nanotechnology. A chief CNSE partner is SEMATECH--a global consortium of major computer chip manufacturers that coordinates cutting-edge R&D projects on semiconductors and is headquartered at CNSE. CNSE has more than 300 members and strategic partners that include large U.S.- and non-U.S.-headquartered private companies such as IBM, Intel, Samsung, and Global Foundries; small and medium-sized companies; universities from across the United States; and regional community colleges and economic development organizations, as well as government-agency sponsors. CNSE facilities allow the development of semiconductors just short of mass production--which is relevant for companies attempting to transition from an innovative concept to a prototype and to prepare for large-scale production. CNSE has developed models of pre-competitive collaboration among its partners, which use high-tech CNSE equipment that would be too costly for many individual companies to purchase. The Center for Nanoscale Science and Technology (CNST) is hosted by a federal laboratory at the National Institute of Standards and Technology (NIST). CNST is a user facility with baseline sponsorship through the Department of Commerce, which is augmented by external commercial funds in the form of user fees paid by industry, academia, government labs, and states. CNST supports the U.S. nanotechnology enterprise from discovery to production by providing industry, academia, NIST, and other government agencies access to world-class nanoscale measurement and fabrication methods and technology. The CNST's shared-use nanotechnology-fabrication capability (called NanoFab) gives researchers economical access to and training on a commercial state-of-the-art tool set required for cutting-edge nanotechnology development. The simple application process is designed to get projects started in a few weeks. Looking beyond the current commercial state of the art, the CNST's nanotechnology-metrology capability offers opportunities for researchers to collaborate on creating and using the next generation of nanoscale measurement instruments and methods. Based on the views of a wide range of experts, nanoscale control and fabrication are creating important new opportunities for our nation--as well as the need not only to recognize challenges, but also, where challenges exist, to act in response to them. The United States leads in some areas of nanomanufacturing, but faces increasing international competition. Challenges specific to U.S. competitiveness include, among others: possible weaknesses associated with prior extensive offshoring in the U.S. funding gap known as the Missing Middle, some U.S. industries, and the lack of a national vision and strategy for the United States to lead or sustain a high level of competitiveness in global nanomanufacturing markets in the years ahead. Experts outlined three main approaches for responding to these challenges: (1) reviewing and renewing policies that undergird U.S. innovation; (2) supporting public-private partnerships that address U.S. funding gaps--especially as these apply to nanomanufacturing; and (3) defining a vision and strategy for achieving and sustaining a high level of U.S. competitiveness in nanomanufacturing. The potential benefit that experts see in pursuing forward-looking approaches such as these is to help chart a favorable course for the global economic position of the United States as we move further into the twenty-first century.

Summary:
Nanotechnology has been defined as the control or restructuring of matter at the atomic and molecular levels in the size range of about 1-100 nanometers (nm); 100 nm is about 1/1000th the width of a hair. The U.S. National Nanotechnology Initiative (NNI), begun in 2001 and focusing primarily on R&D, represents a cumulative investment of almost $20 billion, including the request for fiscal year 2014. As research continues and other nations increasingly invest in R&D, nanotechnology is moving from the laboratory to commercial markets, mass manufacturing, and the global marketplace. Today, burgeoning markets and nanomanufacturing activities are increasingly competitive in a global context--and the potential EHS effects of nanomanufacturing remain largely unknown. GAO was asked to testify on challenges to U.S. competitiveness in nanomanufacturing and related issues. Our statement is based on GAO's earlier report on the Forum on Nano-manufacturing, which was convened by the Comptroller General of the United States in July 2013 (GAO 2014; also referred to as GAO-14-181SP ). That report reflects forum discussions as well as four expert-based profiles of nano-industry areas, which GAO prepared prior to the forum and which are appended to the earlier report. Forum participants described nanomanufacturing as an emerging set of developments that will become a global megatrend: a technological revolution that is now in its formative phases but that many knowledgeable persons--in science, business, and government--expect to burgeon in the years ahead, bringing new opportunities, "disruptive innovation," jobs creation, and diverse societal benefits. They said that the United States likely leads in sponsorship and overall quality of nanotechnology R&D today as well as some areas of nanomanufacturing--for example, nanotherapeutic drug development and the design of semiconductor devices. But they cautioned that the United States faces global-scale competition and is struggling to compete in some industry areas (notably, advanced batteries). Challenges facing U.S. nanomanufacturing include (1) a key U.S. funding gap in the middle stages of the manufacturing-innovation process, as illustrated below; (2) lack of commercial or environmental, safety, and health (EHS) standards; (3) lack of a U.S. vision for nanomanufacturing; (4) extensive prior offshoring in some industries, which may have had unintended consequences; and (5) threats to U.S. intellectual property. Key actions identified by our experts to enhance U.S. nanomanufacturing competitiveness include one or more of the following: (1) strengthen U.S. innovation by updating current innovation-related policies and programs, (2) promote U.S. innovation in manufacturing through public-private partnerships, and (3) design a strategy for attaining a holistic vision for U.S. nanomanufacturing. Key policy issues identified by our experts include the development of international commercial nanomanufacturing standards, the need to maintain support for basic research and development in nanotechnology, and the development of a revitalized, integrative, and collaborative approach to EHS issues.
