1) PLENARY LECTURES ON NANOPARTICLES
The three plenary talks that open the conference will explore nanoparticles, a new class of materials with diverse shapes, size, chemical properties, and programmable functions.
- Joseph DeSimone (UNC-Chapel Hill & NC State University) will describe a roll-to-roll technique developed in his laboratory that exploits lithographic precession from semiconductor processing that allows the fabrication of precisely defined nanoparticles with control over size, shape, deformability and surface chemistry for potential applications in drug delivery. See: http://www.avssymposium.org/Open/SearchPapers.aspx?PaperNumber=BP+NS-SuA-1
- Sharon Glotzer (University of Michigan, Ann Arbor) will show how computer simulations play a critical role in elucidating how nanoparticle shapes, interactions, and programmability can be exploited to make self-assembled materials as sheets, wires, helices, shells and other complex structures. See: http://www.avssymposium.org/Open/SearchPapers.aspx?PaperNumber=BP+NS-SuA-3
- Andre Nel (University of California, Los Angeles) will discuss the UC Center for the Environmental Impact of Nanotechnology (CEIN) and its work developing ways to assess the biocompatability and toxicity of nanomaterials. See: http://www.avssymposium.org/Open/SearchPapers.aspx?PaperNumber=BP+NS-SuA-5 Also see the CEIN website: http://cein.cnsi.ucla.edu
2) SKIN CREAMS FACE OFF AT ATOMIC LEVEL
"The durability of various skin creams were studied by repeated cycling tests. The health and feel of skin are significantly affected by its surface charging and the surface potential of virgin skin, and various cream treated skin was measured to determine the effects of various skin cream using the Kelvin probe method with the AFM..." http://www.avssymposium.org/Open/SearchPapers.aspx?PaperNumber=TR+SS-TuA-11
3) THIN FILMS MIMIC GECKO FEET AND INSECT WINGS
"We have demonstrated that nanostructured polymer thin films can be fabricated by an oblique angle polymerization method. These structures are composed of approximately 40,000,000 aligned columns (approximately 100-150 nm in diameter) per square millimeter similar to the gecko footpad or insect wing. Nanostructured polymer films are envisioned to be useful for specific controlled drug release, metallization (SERS and catalyst applications), tissue targeting as well as antifouling applications..." http://www.avssymposium.org/Open/SearchPapers.aspx?PaperNumber=TF1+SE-TuM-5
4) A SCAFFOLD FOR SPINAL CORD INJURIES
"Spinal cord injuries are one of the most catastrophic and costly types of injuries since damaged axons in the central nervous system are unable to spontaneously regenerate. Although reconstruction of damaged and diseased neural pathways remains a major hurdle, recent research has shown that aligned electrospun fiber mats can provide contact guidance cues to direct axon growth by acting as a bridging device..." http://www.avssymposium.org/Open/SearchPapers.aspx?PaperNumber=BI-MoA-8
5) GROWING NEURONS ON GLASS
"Here, we describe a novel hybrid technology of multi-layered microfluidics with compartmentalized chambers containing multiple neuron types for engineering robust and complex neural networks with high resolution organization of synaptic connections..." http://www.avssymposium.org/Open/SearchPapers.aspx?PaperNumber=BM+MN+MS+TF+BI-ThA-3
6) DRIVE-HEAD/DISK SPACING
"In this talk, I will first review the key surface engineering features (slider air bearing surface, disk topography, overcoat, lubricant, etc.) that enable today’s disk drive sliders to fly at nanometer clearances over disk surfaces. I will then describe work going on in our laboratory both to determine the nanoscale origins of friction and to use this understanding to develop future head-disk interfaces that are expected to run in continuous contact..." http://www.avssymposium.org/Open/SearchPapers.aspx?PaperNumber=TR+SE-WeA-7
7) A NEW WAY TO MAKE MIRRORS
"This paper examines the preparation of silver mirrors by plasma beam deposition, a relatively new technique for thin film fabrication developed and patented by Plasma Quest, Ltd., and licensed by The Aerospace Corporation..." http://www.avssymposium.org/Open/SearchPapers.aspx?PaperNumber=TF2-MoA-10
8) BIOINK: PRINTING THE WAY TO BETTER HEALTH
"We will present the inkjeting of bioink, which may include active compounds such as drugs and living cells as well as non-active, scaffolding materials to build two- and three-dimensional constructs for medical treatment..." http://www.avssymposium.org/Open/SearchPapers.aspx?PaperNumber=IJ+BI+MN+SE+AS-ThM-3
9) NANO-COPPER IMPROVES METHANOL PRODUCTION
"The synthesis of methanol from CO2 and H2 (CO2+3H2 -> CH3OH+ H2O) has attracted considerable attention. It is not only environmentally important due to its application in the conversion of greenhouse gas, CO2, it is also of great industrial significance because the product, methanol, can serve as a raw material for the synthesis of other organic compounds, besides being used as a liquid fuel..." http://www.avssymposium.org/Open/SearchPapers.aspx?PaperNumber=SS3-TuA-4
10) MAKING FUEL CELLS WITH LESS PLATINUM
"Since cost of this precious metal is one of the main barriers for commercialization of fuel cells, many research efforts are addressed to obtaining higher catalytic activity than the standard carbon-supported platinum particle catalysts used in current PEM fuel cells, with a reduced amount of metal..." http://www.avssymposium.org/Open/SearchPapers.aspx?PaperNumber=PS2+TF-WeM-6
11) TUNGSTEN NANOTUBES
Following upon the extensive research into the possible use of carbon nanotubes, scientists explore alternative structures. Nanotubes from tungsten disulfide, with tough mechanical properties, might just be defect free, early experiments show. http://www.avssymposium.org/Open/SearchPapers.aspx?PaperNumber=TR+SS-TuA-10
12) LONG PARTICLES FLOW WITH BLOOD TO DELIVER DRUGS
"Many dispersions of colloidal particles with application in materials processing, biological assays, or medicine contain elongated particles ... Recently these particles have been used in drug delivery applications because of the inability of leukocytes to easily rid them from the circulation..." http://www.avssymposium.org/Open/SearchPapers.aspx?PaperNumber=IJ+BI+MN-WeM-11
13) PROGRAMMABLE MATTER
"In this talk I present an overview of our approach and detail some of the analytical and experimental advances towards a programmable matter system we have recently made..." http://www.avssymposium.org/Open/SearchPapers.aspx?PaperNumber=BM+MN+MS+TF+BI-ThA-1
14) EXTRAORDINARY MAGNETOSRESISTANCE IN GRAPHENE
"Graphene, a single atom-thick layer of graphite, is a promising electronic material, given its high mobility, high current carrying capabilities and linearly dispersive electronic bands. These qualities make it a promising candidate for magnetic field sensing in an extraordinary magnetoresistance device, allowing for the conceptually smallest magnetic spacing in a structure that is free from thermal magnetic noise..." http://www.avssymposium.org/Open/SearchPapers.aspx?PaperNumber=GR+MI-WeM-2
15) RACETRACK MEMORY
"Racetrack Memory promises a novel storage-class memory with the low cost per bit of magnetic disk drives but the high performance and reliability of conventional solid state memories. Unlike conventional memories, the fundamental concept of Racetrack Memory is to store multiple data bits, perhaps as many as 10 to 100, per access point, rather than the typical single bit per transistor..." http://www.avssymposium.org/Open/SearchPapers.aspx?PaperNumber=MI-ThM-3
SHORT COURSES
AVS promotes communication, dissemination of knowledge, recommended practices, research, and education in a broad range of technologically relevant topics. One way that it does this is by offering short courses in areas such as
  • Photovoltaics: The Engineering, Technology and Application of Solar Cells;
  • Surface Analysis, Interface, and Thin Film Analysis: The Major Methods; and
  • Reactive Sputtering and Deposition.
  • To access the complete short course schedule, see: http://www.avs.org/education.schedule.aspx
