Formation, structure, and properties of alkanethiolate monolayers on micrometrically driven hanging mercury drop electrodes were investigated electrochemically. Alkanethiols with the chain length from C8 to C18 were shown to form densely packed (ca. 20.3 Å2/molecule for C12SH), perpendicularly oriented monolayers on mercury in a process involving two(More)
We have investigated electrical properties of symmetric alkanethiolate bilayer junctions formed by contacting two hanging mercury drop electrodes each coated initially with a single alkanethiolate monolayer. Using potentiodynamic, current transient and ac impedance methods, we have shown that the initial, largely all-trans structure of the bilayers becomes(More)
Electron tunneling experiments involving Hg-Hg junctions incorporating two alkanethiolate monolayers are described. Formation of a symmetric junction (Hg-SCn-CnS-Hg) is accomplished by bringing in contact two small (3 × 10-3 cm2) mercury drop electrodes in a 5-20% (v/v) hexadecane solution of an alkanethiol. Formation of asymmetric junctions (Hg-SCn-CmS-Hg)(More)
The electrical conductance of ds-DNA duplexes containing 8-14 base pairs modified at both ends with a -(CH(2))(6)-SH linker was measured in a buffered aqueous solution using electrochemically controlled distance tunneling spectroscopy. The tunneling experiment with self-complementary 5'-(GC)(n)()-3'-(CH(2))(6)-SH (n = 4-7) duplexes attached covalently to a(More)
Rough classification of patients after highly selective vagotomy (HSV) for duodenal ulcer is analysed from the viewpoint of sensitivity of previously obtained results to minor changes in the norms of attributes. The norms translate exact values of pre-operating quantitative attributes into some qualitative terms, e.g. "low", "medium" and "high". An(More)
The rates of electron tunneling through monolayers and bilayers of alkanethiols self-assembled in a potentiostatically controlled Hg-Hg junction are reported. An alkanethiolate monolayer is formed in situ on one or both Hg drops via oxidative adsorption at the controlled potential. Subsequently, the Hg drops are brought into contact using micromanipulators.(More)
