We examine the prospective routes for the design of synthetic/biomacromolecular/inorganic film assemblies for photothermal cell based on biomimetic approach. We demonstrate examples of channel proteins immobilized onto surfaces of silicon single crystals modified with Langmuir–Blodgett and self-assembled monolayers. These proteins can be immobilized in intact, closed-pore conformation. Their st...

The attenuation length, \, of photoelectrons with kinetic energies in the range 500-1500 eV in hydrocarbon films was measured with self-assembled monolayers (SAMs) of n-alkanethiols adsorbed on copper and silver surfaces. This work extends a previous s_tudy using SAMs on gold. The fol lowing values were determined for tr : on Ag, 37 A at 1390 eV, 36 A at I I l9 eV, 35 A at I I 13 eV, 30 A at 91...

The stability of chemical bonds at the molecule− metal interface is of fundamental importance for a majority of applications based on organic materials. It remains, however, extremely difficult to determine this stability using experimental and theoretical methods. A detailed analysis of the static SIMS (SSIMS) data obtained for the homologous series of thiolateand selenolate-based self-assembl...

morphologies. The structural integrity of the CH 3-SAMs was also found to be disturbed substantially at the onset of the ALD process with H 2 O. In order to improve the surface morphology of AlO x on CH 3-SAM surfaces, a two-stage ALD process was developed. In the two-stage ALD process for AlO x , the first stage utilized n-propanol as the oxygen source and the second stage proceeded with H 2 O...

Fabrication and electrochemical characteristics of the meso-2,3-dimercaptosuccinic acid (DMSA) self-assembled monolayer modified gold electrode were described. The modified electrode exhibited increased sensitivity and selectivity for CuII compared to the bare gold electrode by stripping voltammetry and the peak current was proportional to the concentration of CuII in the range of 8.0 10–7 1.2 ...

This paper describes the engineering of patterned calcite films using templating by self-assembled monolayers (SAMs) supported on micropatterned mixed metal substrates. The substrates were prepared by deposition of one metal (Au, Ag) onto the surface of another metal (Au, Ag) through a stencil or photoresist masks. The micropatterning arises from the generation of disordered regions in SAMs at ...

Ultraviolet photoemission spectroscopy, inverse photoemission spectroscopy, and two-photon photoemission spectroscopy are techniques commonly used to examine the electronic structure of surfaces and interfaces. We have used all three to study self-assembled monolayers of 4,4 0-bis(phenylethynyl)benzenethiol on gold, a system often studied for potential application in molecular electronic juncti...

The transition metal ions, Cr‡ , Mo‡ , W‡ and Re‡, abstract one or more fluorine atoms or CmFn groups (m = 1,2; n = 1–5) in collisions with fluorocarbon self-assembled monolayers (F-SAMs). The number of atoms abstracted increases with collision energy, and with W‡ and Re‡ it is possible to maximize a specific scattered product ion by selecting the appropriate collision energy. The collision ene...

Quantized double layer capacitance charging is observed for monolayers of nanometer-sized monolayer protected gold clusters (Au MPCs) anchored to macroscopic gold electrodes. The clusters were anchored in two ways. One method involves ligand place-exchange binding of an MPC covered with a butanethiolate monolayer to a preformed, self-assembled monolayer of 4,4′-thiobisbenzenethiol (TBBT) on Au....
