Improvement in the Electrical Properties of Nickel-Plated Steel Using Graphitic Carbon Coatings
Thin layers of highly conductive graphitic carbon are deposited onto nickelâplated steel substrates using a direct photothermal chemical vapor deposition (PTCVD) technique. The coated nickelâplated steel substrates improve electrical properties (sheet resistance and interfacial contact resistance [ICR]) compared with pristine nickelâplated steel, which makes it a costâeffective alternative to stainless steel for steel producers to use in highâend electrical applications such as energy storage and microelectronics. The coated nickelâplated steel is found to have â10% reduction in sheet resistance and 200 times reduction in ICR (under compression at 140âNâcmâ2), compared with pristine nickelâplated steel. ICR is also three times lower than that of a benchmark goldâcoated stainless steel equivalent at the same pressure

Covalent immobilization of a TiW<sub>5</sub> polyoxometalate on derivatized silicon surfaces
Covalent ties: The polyoxometalate (nBu4N)3[(MeO) TiW5O18] is easily anchored to alkanol-functionalized surfaces of porous and single-crystal silicon (see picture, polyhedra: polyoxometalate, dark blue: Si surface). Scanning tunneling microscopy reveals the growth of 35-50 nm diameter islands on functionalized Si(111), which suggests that the immobilized polyoxometalates act as nucleation sites for electrostatic aggregation. \ua9 2005 Wiley-VCH Verlag GmbH & Co.

A Kinetic Model of the Formation of Organic Monolayers on Hydrogen-Terminated Silicon by Hydrosilation of Alkenes
Covalent and non-covalent attachment and patterning of polypyrrole at silicon surfaces
Two methods for attaching polypyrrole to semiconductor substrates were explored that may prove useful in the construction of molecular-based electronic devices. The use of small molecule alkenyl-pyrrole derivatives allowed covalent cross-linking of polypyrrole to silicon surfaces to form a robust interface. The use of non-covalent, or supramolecular, interactions based on DNA-polypyrrole was also used to fabricate similar interfaces
