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, ...
The Core Apoptotic Executioner Proteins CED-3 and CED-4 Promote Initiation of Neuronal Regeneration in Caenorhabditis elegans
(Public Library of Science, 2012)
A critical accomplishment in the rapidly developing field of regenerative medicine will be the ability to foster repair of neurons severed by injury, disease, or microsurgery. In C. elegans, individual visualized axons ...
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 ...
Neutralizing positive charges at the surface of a protein lowers its rate of amide hydrogen exchange without altering its structure or increasing its thermostability
(American Chemical Society, 2010)
This paper combines two techniques—mass spectrometry and protein charge ladders—to examine the relationship between the surface charge and hydrophobicity of a protein (bovine carbonic anhydrase II; BCA II) and its rate of ...
Integration of paper-based microfluidic devices with commercial electrochemical readers
(Royal Society of Chemistry, 2010)
The combination of simple Electrochemical Micro-Paper-based Analytical Devices (E\(\mu\)PADs) with commercially available glucometers allows rapid, quantitative electrochemical analysis of a number of compounds relevant ...
The Determination of the Location of Contact Electrification-Induced Discharge Events
(American Chemical Society, 2010)
This paper describes a method for determining the location of contact electrification-induced electrical discharges detected in a system comprising a steel sphere rolling in a circular path on an organic insulator. The ...
