Atomic-Scale Measurement of Liquid Metal Wetting and Flow (2007)

N. D. Shinn, C. Daly, R. Limary, T. M. Mayer, T. A. Michalske, T. Kim, ...

1 Category UC-404 The flow behavior of liquid metals at solid interfaces is critically important to successful welding, brazing, soldering and the synthesis of metal/ceramic composites. Continuum...

Chemically Sensitive Interfacial Force Microscopy: Contact Potential Measurements of Self-Assembling Monolayer Films (2006)

Thomas, R. C., Tangyunyong, P., Houston, J. E., Michalske, T. A., Crooks, R. M.

We report contact potential difference (CPD) measurements of n- alkanethiol self-assembling monolayers (SAMs) adsorbed to Au substrates using an organomercaptan-modified Au probe. Our results...

Synthesis and Characterization of Two-Dimensional Molecular Recognition Interfaces (2006)

Crooks, R. M., Chailapakul, O., Ross, C. B., Sun, L., Schoer, J. K.

We have used self-assembly chemistry to synthesize monolayer assemblies that function as molecular recognition interfaces. In the first part of this paper, we show that one-component self-assembled...

Scanning Probe Surface Modification (2006)

Crooks, R. M., Corbitt, T. S., Ross, C. B., Hampden-Smith, M. J., Schoer, J. K.

Nanometer-scale manipulation of surfaces is important because subtle changes in surface structure often result in new electronic, magnetic, photonic, and mechanical materials properties. In this...

Interactions Between Organized, Surface-Confined Monolayers and Vapor- Phase Probe Molecules. 7. Comparison of Self-Assemblying Organomercaptan Monolayers Deposited on Gold from Liquid and Vapor Phases (2006)

Chailapakul, O., Sun, L., Xu, C., Crooks, R. M.

We report a comparative study of the structure and chemistry of methyl-terminated n-alkanethiol self-assembling monolayers (SAMs) formed from liquid and vapor phases. Three different SAMs are...

The Nanometer-Scale Mechanics of Gold Films (2006)

Tangyunyong, P., Thomas, R. C., Houston, J. E., Michalske, T. A., Crooks, R. M., Howard, A. J.

We have used interfacial force microscopy (IFM) to monitor the mechanical deformation of single nanometer-sized grains in Au thin films. Our results show that protruding grains, which represent...

Electrochemistry in Near-Critical and Supercritical Fluids. I. Ammonia. (2002)

Crooks,R. M., Fan,F. F., Bard,A. J.

Cyclic voltammetric and chronocoulometric studies of NH3 containing 0.1 - 0.2 M KI at T and P up to 160 c and 272 atm are reported. Electrochemical generation of solvated electrons is possible even...

Determination of Surface pKa Values of Surface-Confined Molecules Derivitized with pH-Sensitive Pendant Groups. (1998)

Bryant, Mark A., Johnson, Bryan J., Crooks, R. M.

Two methods for in-situ electrochemical measurements of surface pKa values air, reported. The methods are applied to surface-confined monolayers consisting of organomercaptan molecules derivitized...

Synthesis and Characterization of Simple Self-Assembling, Nanoporous Monolayer Assemblies: A New Strategy for Molecular Recognition. (1998)

Chailapakul, Orawon, Crooks, R. M.

Composite monolayer films spontaneously adsorb onto the surface of Au from an ethanolic mixture of two mercaptans to form a nanoporous surface. The monolayers consist of an electron...

Substrate Effects on the Nanometer-Scale Mechanics of Gold Films. (1998)

Tangyunyong, P., Thomas, R. C., Houston, J. E., Michalske, T. A., Crooks, R. M.

We have used interfacial force microscopy (IFM) and contact-mechanics analysis to quantitatively determine the deformation behavior and the mechanical properties of nanometer-size grains in...

Polymeric Self-Assembled Monolayers. 4. Synthesis, Characterization, and Stability of omega-Functionalized, Self-Assembled Diacetylenic and Polydiacetylenic Monolayers. (1998)

Kim, T., Chan, K. C., Crooks, R. M., Ye, Q., Sun, L.

Here we discuss the preparation and characterization of photopolymerizable, self-assembled monolayers (SAMs) that consist of acid-, hydroxyl-, and methyl-terminated n-alkylthiois containing a...

Preparation of Cu Nanoclusters within Dendrimer Templates (1998)

Zhao, M., Sun, L., Crooks, R. M.

A new template synthesis strategy for preparing Cu nanoclusters within dendrimer 'nanoreactors' is demonstrated. Hydroxyl-terminated polyamidoamine (PAMAM) dendrimers of generation higher than 2 act...
