31. Characterizing Equilibrium in Epitaxial Growth
Topic: Nanotechnology
Published: 2/20/2012
Authors: Paul Nathan Patrone, Russel Caflisch, Dionisios Margetis
Abstract: Using a kinetic model of epitaxial growth, we describe how geometry controls kinetic pathways through which external deposition influences the state of a vicinal surface. The state of the surface is determined by three key, adjustable parameters: th ...

32. Reaction Network Governing Diphosphine-Protected Gold Nanocluster Formation from Nascent Cationic Platforms
Topic: Nanotechnology
Published: 2/16/2012
Authors: John M. Pettibone, Jeffrey W Hudgens
Abstract: We identify the reaction network governing gold monolayer protected cluster (MPC) formation during the reduction of Au(PPh^d3^)Cl and L^u5^ (L^u5^ = 1,5-bis(diphenylphosphino)pentane) in solutions. UV-vis spectroscopy and electrospray ionization mass ...

33. Quantitative Measurements of the Size Scaling of Linear and Circular DNA in Nanofluidic Slitlike Confinement
Topic: Nanotechnology
Published: 2/14/2012
Authors: Elizabeth A Strychalski, Jon C Geist, Michael Gaitan, Laurie E Locascio, Samuel M Stavis
Abstract: Quantitative size measurements of single linear and circular DNA molecules in nanofluidic slitlike confinement are reported. A novel experimental method using DNA entropophoresis down a nanofluidic staircase implemented comprehensive variation of sl ...

34. Copper oxide nanoparticle mediated DNA damage in terrestrial plant models
Topic: Nanotechnology
Published: 12/22/2011
Authors: Bryant C Nelson, Donald H Atha, Elijah J Petersen, Huanhua Wang, Danielle Cleveland, Richard D Holbrook, Pawel Jaruga, M Miral Dizdar, Baoshan Xing
Abstract: Engineered nanoparticles, due to their unique electrical, mechanical and catalytic properties, are presently found in many commercial products and will be intentionally or inadvertently released at increasing concentrations into the natural environme ...

35. Nanometrology Using Through-Focus Scanning Optical Microscopy Method
Topic: Nanotechnology
Published: 12/21/2011
Authors: Ravikiran Attota, Richard M Silver
Abstract: We present an initial review of a novel through-focus scanning optical microscopy (TSOM) imaging method that produces nanometer dimensional measurement sensitivity using a conventional bright-field optical microscope. In the TSOM method a target is ...

37. Spectral Line-by-Line Pulse Shaping of On-Chip Microresonator Frequency Combs
Topic: Nanotechnology
Published: 12/1/2011
Authors: Fahmida Ferdous, Houxun H. Miao, Daniel E. Leaird, Kartik A Srinivasan, Jian Wang, Lei Chen, Leo Tom Varghese, Andrew M Weiner
Abstract: We report, for the first time to the best of our knowledge, spectral phase characterization and line-by-line pulse shaping of an optical frequency comb generated by nonlinear wave mixing in a micro-ring resonator. The comb is compressed to a train o ...

39. Far-field superfocusing with optical fiber based surface plasmonic lens made of nanoscale concentric annular slits
Topic: Nanotechnology
Published: 9/30/2011
Authors: Yuxiang Liu, Hua Xu, Felix Stief, Nikolai B Zhitenev, Miao Yu
Abstract: We present experimental demonstration of three-dimensional superfocusing by using an optical fiber based surface plasmonic (SP) lens with nanoscale concentric annular slits. To the best of our knowledge, this is the first time that a far-field, sub-d ...

40. Strategies for Nanoscale Contour Metrology using Critical Dimension Atomic Force Microscopy
Topic: Nanotechnology
Published: 9/30/2011
Authors: Ndubuisi George Orji, Ronald G Dixson, Andras Vladar, Michael T Postek
Abstract: Contour metrology is one of the techniques used to verify optical proximity correction (OPC) in lithography models. The use of these methods, which are known as resolution enhancement techniques (RET), are necessitated by the continued decrease in f ...
