Abstract: An anvil driving assembly, anvil driving tool, and method for installing rivetless floating nut plates in workpieces. The tool and method are capable of pulling a rivetless nut plate sleeve into a countersunk hole in the workpiece simultaneously with flaring the open end of the nut plate sleeve.
Abstract: A striking and pulling tool, such as a hammer, having separate head elements secured to opposing sides of a handle. The tool may be part of a system with interchangeable components.
Abstract: A method of manufacturing an array of nanostuctures, such as quantum dots, having a controlled diameter and a substrate with an ordered array of nanostructures having a controlled diameter. In a preferred embodiment of the invention, nanoscale features are produced on a substrate by using a porous crystalline protein as a template for preparing an etch/deposition mask having a regular array of nanoscale pores of a diameter different from the protein template. The mask may be used to etch a regular array of nanoscale wells and/or deposit nanoclusters of adatoms on the surface of an underlying substrate. A further embodiment of the invention is a substrate including an ordered array of nanoscale features having a controlled size.
