Abstract: Method for making a low cost, light weight impact deflecting material, comprising directionally aligned single walled carbon nanotubes in an epoxy resin composition, that is near impervious to bullets fired at close range at all angles of incidence, that does not deteriorate upon abrasion or when exposed to wide ranges of temperature and humidity, and that when used to construct a protective shield for a body armor vest protects the wearer from blunt trauma effects.

Abstract: An improved substrate for Raman spectroscopy of an analyte comprises a porous metal film. Enhancement factors and uniformity of the substrate can be enhanced by electrochemical roughening of the film. Improved sensors and spectrometers using such substrates are also described.

Abstract: A method for selectively assembling a molecular device on a substrate comprises contacting the first substrate with a solution containing molecular devices; impeding bonding of the molecular devices to the substrate such that application of a voltage potential to the substrate results in assembly of the molecular device on the substrate at a rate that is at least 1.5 times the rate of assembly of the molecular device on a voltage-neutral substrate; and applying a voltage potential to the substrate so as to cause the molecular devices to assemble on the substrate. More specifically, selective assembly can be obtained by providing a mixture comprising protected molecular devices in solution; removing protective groups from some of the molecular devices; activating the de-protected molecular devices; contacting the substrate with the solution; and allowing the activated devices to bond to the substrate such that the they assemble on the first substrate.

Abstract: A molecular computer is formed by establishing arrays of spaced-apart input and output pins on opposing sides of a containment, injecting moleware in solution into the containment and then allowing the moleware to bridge the input and output pins. Moleware includes molecular alligator clip-bearing 2-, 3-, and molecular 4-, or multi-terminal wires, carbon nanotube wires, molecular resonant tunneling diodes, molecular switches, molecular controllers that can be modulated via external electrical or magnetic fields, massive interconnect stations based on single nanometer-sized particles, and dynamic and static random access memory (DRAM and SRAM) components composed of molecular controller/nanoparticle or fullerene hybrids. The current-voltage characteristics that result from the bridging between input and output arrays can be ascertained using another computer to identify the bundles of inputs and corresponding outputs that provide a truth table for the specific functions of the computer.

Abstract: The use of modifiers such as disulfides and phosphines is particularly effective in modifying the properties of metals such as noble metals and silver. For example, disulfides are useful for modifying the properties of gold and silver while phosphines are useful for metals such as platinum and palladium. Through treatment with a suitable modifier it is possible to change properties such as the wetting and adhesion properties of the treated metal. Additionally, the use of modifiers to treat a desired substrate enhances formation of continuous metal films on this substrate.
