Microreactor-Assisted NanoManufacturing: Applications and OpportunitiesBrian Paul, Oregon State University
NEW: Microreactor-assisted nanomanufacturing techniques for various electronic, optical, thermal and catalytic films.
CHALLENGES: As compared to conventional synthesis and deposition of nanostructured films: fewer processing steps, higher energy efficiency, shorter cycle times, agglomeration control, higher yield, purer product, and lower solvent usage.
DESCRIPTION: Microreactor-assisted nanomanufacturing is a flexible, scalable, and versatile platform for deploying nanostructured thin films, combining the merits of microreactor technology with liquid-phase nanomaterial chemistries. Microreactor-assisted Nanomaterial Deposition(TM) employs real time nucleation, growth, and functionalization of nanomaterials for deposition and assembly of nanostructured films. By tightly controlling the reaction chemistry, continuous flow microreactors enable increases in macromolecular yield and dramatic reductions in the size dispersity of nanoparticles produced. This advantage has been harnessed to deposit a wide variety of functional films onto moving or stationary substrates with strong adhesion and no post processing showing a pathway to continuous production and scale-up. The potential to displace current industrial deposition methods and produce new nanostructured films with microreactor-assisted solution deposition methods will be discussed. 11:15 a.m. – 12:00 p.m.
Simultaneous Bottom-Up and Top-Down Silicon NanoManufacturing and Monolithic Integration with MicroManufacturingG. Logan Liu, University of Illinois at Urbana-Champaign
NEW: A mixture gas chamber for multiple concurrent and coupled gas-solid phase-transition chemical reactions using plasma to activate the reactions allows for the simultaneous silicon nanopillar etching and oxide nanoparticle synthesis at the same localized points and for monolithic integration of nanostructures on microstructures.
CHALLENGES: Bottom-up and top-down processes can occur simultaneously and influence each other in a single-step process technology permitting ultrahigh-throughput, lithography-less, wafer-scale, and room-temperature nanomanufacturing
DESCRIPTION: The manufacturing of nanostructured devices relies on either bottom-up approaches such as synthesis or growth process or top-down approaches such as lithography or etching process. A synchronized, and simultaneous top-down and bottom-up nanofabrication approach called simultaneous plasma enhanced reactive ion synthesis and etching (SPERISE) will be presented. For the first time the atomic addition and subtraction of nanomaterials are concurrently observed and precisely controlled in a single-step process permitting ultrahigh-throughput, lithography-less, wafer-scale, and room-temperature nanomanufacturing. Rapid low-cost manufacturing of high-density, high-uniformity, light-trapping nanocone arrays on bulk scale and microstructures was demonstrated on single crystalline and polycrystalline silicon wafers, as well as amorphous silicon thin films. The SPERISE nanomanufacturing mechanisms also provide a general guideline to designing new SPERISE methods for other semiconductor materials.

MEMS as an Enabling Technology for Nano FabricationJoseph Fragala, Nanoink
NEW: MEMS can be used to enable NanoFabrication, but it may not work the first time. Some examples of the difficulties moving new MEMS devices from concept to production will be included. Applications for the technology vary from materials research to protein chips.
CHALLENGES: Understanding a method to bridge the scale from macro to nano using MEMS.
DESCRIPTION: MicroElectroMechanical Systems, or MEMS, can bridge the gap between the meso-scale, reached by traditional machine tools, and the nanoscale. MEMS tools such as passive pens, active pens, 2D arrays of pens and ink delivery devices that enable Dip Pen NanoLithography® or DPN® will be presented. These devices have overall dimensions that measure in millimeters, yet they allow the printing of features that range from 20 nm up to 10's of microns. The challenges of moving from a concept through development into manufacturing the products will be described. None of these products worked at first, all needed either redesign or additional process development. Even after being in production, some products have had yield issues that had to be resolved quickly to not upset shipments to customers. Some of the research and commercial applications of this technology will be briefly shared. 2:15 p.m. - 3:00 p.m.
Electric TweezersDonglie Fan, University of Texas-Austin
NEW: Electric tweezers have been used to hold, to place, and to assemble individual nanowires into simple NEMS devices, such as nano oscillators and nano-motors. A single Au nanowire functionalized with a specific drug has been manipulated by electric tweezers to deliver a well defined quantity of drugs to a single mammalian cell surrounded by others that were unaffected.
CHALLENGE: Electric tweezers can transport, assemble, and rotate nano entities with precisely controlled angle, speed, and direction.
DESCRIPTION: Electric tweezers utilize DC and AC electric fields through voltages applied on patterned electrodes to manipulate nanoentities suspended in a liquid. Nanowires with a large aspect ratio are particularly suitable for use in electric tweezers for patterning, assembling, and manipulation. Despite operating in the regime of extremely small particle Reynolds number, electric tweezers can manipulate nanowires with high precision to follow any prescribed trajectory, to rotate nanowires with controlled chirality, angular velocity and rotation angle, and to assemble nanowires to fabricate nanoelectromechanical system (NEMS) devices such as nanomotors and nano-oscillators. Electric tweezers have also been used to transport in a highly controlled manner drug-carrying functionalized nanowires for cell-specific drug delivery. 3:00 p.m. – 3:30 p.m.

Covetics: A Nano Material That is a New Type of MatterSteve Vetter, Molecular Manufacturing
NEW: A novel nanomaterial that may offer insights into other potential materials with applications in photovoltaics, ballistics, thermal management, nanoelectronics, and aviation.
CHALLENGE: Integrating carbon into metals so it does NOT phase separate, decrease density of electrical conductors, and increase thermal and electrical conduction, especially in alloys.
DESCRIPTION: A novel combination of carbon and metal which results in materials that have some of the best properties of each and do not phase separate upon melting. These materials, called Covetics, are so unique that the navy has termed them "a new form of matter". This presentation discusses the content of these materials, various analysis and test results, the resulting properties, and potential near-term and long-term applications. To the extent that the expected patent issuances are complete, more information on structure and process will be shared. 4:15 p.m. – 5:00 p.m.
Towards Commercialization of Graphene MaterialsElena Polyakova, Graphene Laboratories
NEW: Insight to manufacturing techniques as well as the future applications of graphene in every day products.
CHALLENGE: Where, when and how graphene can be used.
DESCRIPTION: Graphene is quickly becoming a likely replacement for current materials used in a variety of applications. This includes in the near term replacing indium tin-oxide for use in touch-screens and possibly replacing silicon in consumer electronics. One of the biggest challenges in commercializing graphene for everyday use is scaling up graphene synthesis so that more high-quality material can be created at an increasingly affordable price. The technology to scale up production of graphene is being quickly advanced. There are many lessons from the past to help pave the way for the successful commercialization of graphene. An overview of why the initial attempts in commercial development of products based on carbon nanotubes failed to live up to early expectations, and what graphene researchers and suppliers can do to avoid the same fate will be presented. A snapshot of the current state in the development of graphene materials as well as key technological roadblocks will be discussed. Graphene will be compared with conventional materials and a vision of a roadmap for graphene-enabled materials and products will be shared. 5:00 p.m. – 6:30 p.m.
Day Two: Thursday, March 299:00 a.m. – 9:45 a.m.
Antimicrobial Technologies in Design and Manufacturing of Medical DevicesArif Sirinterlikci & Christina Acors, Robert Morris University
NEW: Designing and manufacturing medical devices to work with or without sterilization and future applications of the technology
CHALLENGES: Review of the current state and future of nano particle/ion-based antimicrobial technologies in medical devices.
DESCRIPTION: The concept of antimicrobials has been successfully utilized in a wide range of products from consumer products to medical devices. This new technology needs to coexist with the sterilization processes in the medical device field, with the hope of eliminating sterilization in the future. However, it currently offers a feasible alternative for preventing healthcare acquired infections, associated deaths and costs which are not negligible. It also remains challenging for medical device manufacturers to obtain 510(k) approvals from FDA. However, strides are being made, and more and more antimicrobial reinforced medical devices are becoming available as other entities such as ASTM, ISO, JIS, and USP are becoming more involved in testing of the materials.
The current state and future of antimicrobial technologies including nano particle- and ion-based will be presented. The materials and processes as well as design and manufacturing of medical devices will be covered. FDA approval processes will also be included in the concluding section in addition to the sterilization methods. 9:45 a.m. – 10:30 a.m.
Occupational and Environmental Health and Safety: Controls to Reduce Nanoparticle ExposureCandace Tsai, University of Massachusetts-Lowell
NEW: Engineering control principles and methods which can effectively reduce exposure to nanoparticles.
CHALLENGES: Proactively handling nanomaterials.
DESCRIPTION: Case studies will be discussed including the control strategies found to be effective. Research laboratories and industrial manufacturers were in need of economic and straightforward control methods. Modifications to currently-available controls were required for the nano-industry to move forward to the next phase. Research results showed that the currently-available nanoparticle control methods can provide excellent performance when used properly and efficiently. Understanding the behavior of airborne nanomaterials, such as their response to the surrounding airflow pattern, is one of the key elements for controlling airborne nanoparticle exposure. Local exhaust ventilation systems (LEVs) such as fume hoods, powder handling enclosure and biological safety cabinet have been investigated to evaluate the potential for nanoparticle release and subsequent worker exposure when handling nanoparticles, the optimum approaches to reduce associated exposure using LEVs will be presented. 10:30 a.m. – 11:00 a.m.

PANEL: Recent Advances and Challenges in NanoManufacturing
Current nanotechnology research focuses on surface modification, matching molecules, and "sockets" at the level of manipulating several to several hundred particles or molecules to be assembled into desirable configurations. Commercial scale-up and the promised economic windfall, however, will not be realized unless one can perform high-rate/high-volume assembly of nanoelements economically using environmentally benign processes. This includes understanding what is essential for a rapid multi-step or reel-to-reel process, as well as for accelerated-life testing of nanoelements and defect-tolerance.
The panel will address moving from the R&D phase and prototyping to the commercialization phase, and preferably onto volume production. Current developments and successes in transitioning research into commercial products will also be discussed. Each panelist will make a short presentation, which will be followed by questions from conference participants. Don't miss this chance to pose your question to a group of nanotechnology leaders. 12:30 p.m. – 1:30 p.m.
