Formation, structure, and properties of alkanethiolate monolayers on micrometrically driven hanging mercury drop electrodes were investigated electrochemically. Alkanethiols with the chain length from C 8 to C 18 were shown to form densely packed (ca. 20.3 Å 2 /molecule for C 12 SH), perpendicularly oriented monolayers on mercury in a process involving two(More)
Electron tunneling experiments involving Hg-Hg junctions incorporating two alkanethiolate monolayers are described. Formation of a symmetric junction (Hg-SC n-C n S-Hg) is accomplished by bringing in contact two small (3 × 10-3 cm 2) mercury drop electrodes in a 5-20% (v/v) hexadecane solution of an alkanethiol. Formation of asymmetric junctions (Hg-SC n-C(More)
Scanning electrochemical microscopy (SECM) is used to probe long-range charge transport (CT) through DNA monolayers containing the redox-active Nile Blue (NB) intercalator covalently affixed at a specific location in the DNA film. At substrate potentials negative of the formal potential of covalently attached NB, the electrocatalytic reduction of(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)
BACKGROUND Penetrating neck trauma involving foreign bodies is a rare event in European countries. Due to its relatively high mortality rate, the correct management strategy must be initiated from the beginning to prevent fatal complications. In the medical literature, there are only a few cases describing foreign bodies penetrating the cervical spine.(More)
