The “Standard Model” of elementary particle physics encompasses the progress that has been made in the past half-century in understanding the weak, electromagnetic, and strong interactions. The name was apparently bestowed by my Ph. D. thesis advisor, Sam B. Treiman, whose dedication to particle physics kindled the light for so many of his students during those times of experimental and theoret...

We present a theoretical study of spatially modulated phases in self-assembled monolayers of mixed surfactants. We propose two models which are appropriate, respectively, for monolayers at a fluid-fluid interface and monolayers on a solid substrate. We show that in both cases, the molecular shape asymmetry, coupled with the local composition variation, can lead to spontaneous formation of perio...

The use of the immunoperoxidase monolayer assay (IPMA) has been limited to challenge model investigations10–11 and a few field studies. Guedes et al12 reported 100% specificity and 89% sensitivity at a serum dilution of 1:30 for the IPMA serological test. Guedes et al13 also determined that there was 98.6% agreement between the IFAT and the IPMA tests in experimentally infected pigs, concluding...

We investigate a wetting reversal transition in thin films of two-phase mixtures of poly(ethylenepropylene) (PEP) and its deuterated analog (dPEP) on substrates covered by self-assembled monolayers (SAM) whose surface energy, gSAM, is tuned by varying the SAM composition. As gSAM increases from 21 to 24 mJ m2, a transition from a dPEP PEP dPEP SAM to a dPEP PEP SAM structure occurs at increasin...

Electronically programmable memory devices utilizing molecular self-assembled monolayers are reported. The devices exhibit electronically programmable and erasable memory bits compatible with conventional threshold levels and a memory cell applicable to a random access memory is demonstrated. Bit retention times .15 min have been observed. © 2001 American Institute of Physics. @DOI: 10.1063/1.1...

A review on the mechanisms and characterization methods of electronic transport through self-assembled monolayers (SAMs) is presented. Using SAMs of alkanethiols in a nanometre scale device structure, tunnelling is unambiguously demonstrated as the main intrinsic conduction mechanism for defect-free large bandgap SAMs, exhibiting well-known temperature and length dependences. Inelastic electron...

The electrical properties of self-assembled monolayers (SAMs) of organic molecules on metal surfaces have gained particular interest due to their potential applications in nanometer-scaled electronics systems [1]. Understanding the transport mechanism through these thin molecular films as well as the dependence of the conductivity on the molecular length and structure, the applied load and the ...

Microcantilevers modified with a self-assembled monolayer respond sensitively to specific ion concentrations. Here, we report the detection of trace amounts of CrO4(2-) using microcantilevers modified with a self-assembled monolayer of triethyl-12-mercaptododecylammonium bromide. The self-assembled monolayer was prepared on a silicon microcantilever coated with a thin layer of gold on one side....
