Vibronic Coupling in Asymmetric Bichromophores: Experimental Investigation of Diphenylmethane-d5

August 14, 2014
Author(s)
Nathan Pillsbury, Nathanael M. Kidwell, Benjamin Nebgen, Lyudmila V. Slipchenko, Kevin O. Douglass, John R. Cable, David F. Plusquellic
Vibrationally and rotationally resolved electronic spectra of diphenylmethane-d5 (DPM-d5) are reported in the isolated-molecule environment of a supersonic expansion. While small, the asymmetry induced by deuteration of one of the aromatic rings is

Attachment of a Reduction-Oxidative Active Diruthenium Compound to Au and Si Surfaces by Click Chemistry

August 10, 2014
Author(s)
Sujitra J. Pookpanratana, Joseph W. Robertson, Curt A. Richter, Christina A. Hacker, Lee J. Richter, Julia Savchenko, Steven Cummings, Tong Ren
We report the formation of molecular monolayers containing redox-active diruthenium(II,III) compound to gold and silicon surfaces via “click” chemistry. The use of Cu-catalyzed azide-alkyne cycloaddition enables modular design of molecular surfaces and

Polyelectrolyte Multilayers in Microfluidic Systems for Biological Applications

July 31, 2014
Author(s)
Saugandhika S. Minnikanti, Aveek Gangopadhyay, Darwin Reyes-Hernandez
The formation of polyelectrolyte multilayers (PEMs) for the first time two decades ago demonstrating the assembly on charged substrates in a very simple and efficient way have proven to be a reliable method to obtain structures tunable at the nanometer

High-Speed Coherent Raman Fingerprint Imaging of Biological Tissues

July 20, 2014
Author(s)
Charles H. Camp, Young J. Lee, John M. Heddleston, Christopher M. Hartshorn, Angela R. Hight Walker, Jeremy N. Rich, Justin D. Lathia, Marcus T. Cicerone
We have developed a coherent Raman imaging platform using broadband coherent anti-Stokes Raman scattering (BCARS) that provides an unprecedented combination of speed, sensitivity, and spectral breadth. The system utilizes a unique configuration of laser

Low Temperature Plasma for Bevel Crater Depth Profiling of Crosslinking Organic Multilayers: Comparison with C60 and Argon Gas Cluster Sources

July 6, 2014
Author(s)
Shinichiro Muramoto, Derk Rading, Brian G. Bush, John G. Gillen, David G. Castner
A model delta layer system made of thin films of an organometallic chelate and an aromatic molecule (aluminum hydroxyquinolinate and bathocuproine), both that crosslink under traditional ion beam irradiation, was used to evaluate the effectiveness of using

Final report of the key comparison CCQM-K98: Pb isotope amount ratios in bronze

July 1, 2014
Author(s)
Jochen Vogl, Yong-Hyeon Yim, Kyoung-Seok Lee, Heidi Goenaga-Infante, Dmitriy Malinowskiy, Tongxiang Ren, Jun Wang, Robert D. Vocke Jr., Karen E. Murphy, Naoko Nonose, Olaf Rienitz, Janine Noordmann, Teemu Naeykki, Timo Sara-Aho, Bet?l Ari, Oktay Cankur
Isotope amount ratios are proving useful in an ever increasing array of applications that range from studies unravelling transport processes, to pinpointing the provenance of specific samples as well as trace element quantification by using isotope

A Demonstration of Fast and Accurate Discrimination and Quantification of Chemically Similar Species Utilizing a Single Cross-Selective Chemiresistor

June 14, 2014
Author(s)
Alexander (. Vergara Tinoco, Kurt D. Benkstein, Christopher B. Montgomery, Stephen Semancik
Performance characteristics of gas-phase microsensors will determine the ultimate utility of these devices for a wide range of chemical monitoring applications. Considerable effort has led to electronic nose devices that utilize multiple cross-selective
