  1. Postformation Modification of SAMs: using click chemistry to functionalize organic surfaces.

    Langmuir 25(19):11480 (2009) PMID 19788212

    We have investigated a recently established strategy of modifying organic surfaces exposed by thiolate SAMs (self-assembled monolayers) deposited on Au substrates by employing so-called click chemistry. This term is used to denote a modified Huisgen 1,3-dipolar cycloaddition. We demonstrate the ...
  2. Enabling organosilicon chemistries on inert polymer surfaces with a vapor-deposited silica layer.

    Langmuir 25(19):11541 (2009) PMID 19655704

    Given the large surface area-to-volume ratios commonly encountered in microfluidics applications, the ability to engineer the chemical properties of surfaces encountered in these applications is critically important. However, as various polymers are rapidly replacing glass and silicon as the cho...
  3. Solvent-assisted dewetting during chemical vapor deposition.

    Langmuir 25(19):11555 (2009) PMID 19670895

    This study examines the use of a nonreactive solvent vapor, tert-butanol, during initiated chemical vapor deposition (iCVD) to promote polymer film dewetting. iCVD is a solventless technique to grow polymer thin films directly from gas phase feeds. Using a custom-built axisymmetric hot-zone reac...
  4. Generation of clean iron structures by electron-beam-induced deposition and selective catalytic decomposition of iron pentacarbonyl on Rh(110).

    Langmuir 25(19):11930 (2009) PMID 19630434

    We explore the electron-beam-induced deposition (EBID) of iron pentacarbonyl, Fe(CO)5, in ultrahigh vacuum (UHV) on clean and modified Rh(110) surfaces by scanning electron microscopy (SEM), scanning Auger microscopy (SAM), and local Auger electron spectroscopy (AES). In EBID a highly focused el...
  5. Synthesis and spectroscopic studies of composite gold nanorods with a double-shell structure composed of spacer and cyanine dye J-aggregate layers.

    Langmuir 25(19):11802 (2009) PMID 19655781

    The composite gold nanorods (Au NRs) having a double-shell structure composed of Au NR (core), spacer layer (inner shell), and J-aggregate (JA) layer (outer shell) have been synthesized to examine the spectroscopic properties of the hybrid system in which the localized surface plasmon is coupled...
  6. Anisotropic reversible aggregation of latex nanoparticles suspended in a lyotropic nematic liquid crystal: effect of gradients of biaxial order.

    Langmuir 25(19):11849 (2009) PMID 19702247

    We studied the anisotropic aggregation of spherical latex particles dispersed in a lyotropic liquid crystal presenting three nematic phases: calamitic, biaxial, and discotic. We observed that in the nematic calamitic phase aggregates of latex particles are formed, which become larger and anisotr...
  7. Interaction of cationic hydrophobic surfactants at negatively charged surfaces investigated by atomic force microscopy.

    Langmuir 25(19):11509 (2009) PMID 19746942

    Atomic force microscopy was used to study the adsorption of the surfactant octadecyl trimethyl ammonium chloride (C18TAC) at a low concentration (0.03 mM) to negatively charged surfaces in water. Atomic force microscopy tips were functionalized with dimethyloctadecyl(3-tripropyl)ammonium chlorid...
  8. Photosensor based on an FET utilizing a biocomponent of photosystem I for use in imaging devices.

    Langmuir 25(19):11969 (2009) PMID 19731941

    We have investigated a photosensor that consists of a field emission transistor (FET) utilizing the biocomponent of the photosystem I (PSI) protein complex for use in an imaging device. The PSI was immobilized on a gold electrode via the self-assembling monolayer (SAM) of 3-mercapto-1-propanesul...
  9. A peculiar phase transition of plasmalogen bilayer membrane under high pressure.

    Langmuir 25(19):11265 (2009) PMID 19697955

    The bilayer phase transition of plasmalogen, monounsaturated plasmenylcholine 1-O-1'-(Z)-octadecenyl-2-oleoyl-sn-glycero-3-phosphocholine (Plg-SOPC), was examined by differential scanning calorimetry, high-pressure transmittance, and fluorescence techniques. The bilayer properties of Plg-SOPC su...
  10. Effects of capillary condensation in adhesion between rough surfaces.

    Langmuir 25(19):11727 (2009) PMID 19788224

    Experiments on the effects of humidity in adhesion between rough surfaces have shown that the adhesion energy remains constant below a critical relative humidity (RHcr) and then abruptly jumps to a higher value at RHcr before approaching its upper limit at 100% relative humidity. A model based o...
