Abstract: A nonmodular tibial prosthesis having a retainer for a modular bearing on the superior surface of a tibial base, a nonmodular primary bearing directly molded to the base, and a mechanical release member mounted on the tibial base in contact with the nonmodular primary bearing. The release member includes a wedge portion with a superiorly posteriorly inclined face, and is designed to be driven anteriorly upon actuation so as to force the primary bearing off of the tibial base, after which the primary bearing and release member are removed and replaced with a modular bearing.

Abstract: A method is provided for the preparation of nanoscale particle arrays having highly uniform crystals of metal, semiconductor or insulator materials grown in nanopores in the surface of a substrate, wherein the method uses pulse-reverse electrodeposition of metals with a rectangular or square waveform in order to generate high homogeneity of crystals and high in-plane or out-of-plane anisotropy in a controlled manner, enabling the creation of a variety of devices, including but not limited to high density storage media.

Abstract: A unimolecular electrical rectifier is prepared by forming a metal electrode on a substrate such as silicon, glass or quartz. One or more organic monolayers are formed on the electrode by Langmuir-Blodgett film transfer methods, and the resulting organic layer is dried. The organic layer is super cooled to a temperature of about −200° C., to permit formation of a second electrode over the organic layer, without damaging the electrical properties of the organic layer. The two electrodes have the same composition, and the organic layer is a ground stage zwitteronic compound.
