Subnanometer Replica Molding of Molecular Steps on Ionic Crystals
(American Chemical Society, 2010)
Replica molding with elastomeric polymers has been used routinely to replicate features less than 10 nm in size. Because the theoretical limit of this technique is set by polymer-surface interactions, atomic radii, and ...
Survey of Materials for Nanoskiving and Influence of the Cutting Process on the Nanostructures Produced
(American Chemical Society, 2010)
This paper examines the factors that influence the quality of nanostructures fabricated by sectioning thin films with an ultramicrotome (“nanoskiving”). It surveys different materials (metals, ceramics, semiconductors, ...
\((Sn,Al)O_x\) Films Grown by Atomic Layer Deposition
(American Chemical Society, 2011)
\((Sn,Al)O_x\) composite films with various aluminum (Al) to tin (Sn) ratios were deposited using an atomic layer deposition technique. The chemisorption behavior of cyclic amide of tin(II) and trimethylaluminum were ...
Overview of ALD Precursors and Reaction Mechanisms
(2011)
Successful use of ALD requires suitable chemical precursors used under reaction conditions that are appropriate for them. There are many requirements for ALD precursors: sufficient volatility, thermal stability and reactivity ...
Analysis of Inorganic Polyphosphates by Capillary Gel Electrophoresis
(American Chemical Society, 2010)
This paper describes the development of a method that uses capillary gel electrophoresis (CGE) to analyze mixtures of inorganic polyphosphate ((P\(_i\))\(_n\)). Resolution of (P\(_i\))\(_n\) on the basis of n, the number ...
Patterned Paper as a Template for the Delivery of Reactants in the Fabrication of Planar Materials
(Royal Society of Chemistry, 2010)
This account reviews the use of templates, fabricated by patterning paper, for the delivery of aqueous solutions of reactants (predominantly, ions) in the preparation of structured, thin materials (e.g., films of ionotropic ...
Mechanism of Rectification in Tunneling Junctions Based on Molecules with Asymmetric Potential Drops
(American Chemical Society, 2010)
This paper proposes a mechanism for the rectification of current by self-assembled monolayers (SAMs) of alkanethiolates with Fc head groups (SC\(_{11}\)Fc) in SAM-based tunneling junctions with ultra-flat Ag bottom electrodes ...
Charge Transport and Rectification in Arrays of SAM-Based Tunneling Junctions
(American Chemical Society, 2010)
This paper describes a method of fabrication that generates small arrays of tunneling junctions based on self-assembled monolayers (SAMs); these junctions have liquid-metal top-electrodes stabilized in microchannels and ...
Mutation Induced Extinction in Finite Populations: Lethal Mutagenesis and Lethal Isolation
(Public Library of Science, 2012)
Reproduction is inherently risky, in part because genomic replication can introduce new mutations that are usually deleterious toward fitness. This risk is especially severe for organisms whose genomes replicate ...
Synchronized Time-Lens Source for Coherent Raman Scattering Microscopy
(Optical Society of America, 2010)
We use the time-lens concept to demonstrate a new scheme for synchronization of two pulsed light sources for biological imaging. An all fiber, 1064 nm time-lens source is synchronized to a picosecond solid-state Ti: Sapphire ...
