There have been problems in that a dedicated apparatus is needed for a conventional method of manufacturing an organic thin film transistor and in that: a little amount of an organic semiconductor film is formed with respect to a usage amount of a material; and most of the used material is discarded. Further, apparatus maintenance such as cleaning of the inside of an apparatus cup or chamber has needed to be frequently carried out in order to remove the contamination resulting from the material that is wastefully discarded. Therefore, a great cost for materials and man-hours for maintenance of apparatus have been required. In the present invention, a uniform organic semiconductor film is formed by forming an aperture between a first substrate for forming the organic semiconductor film and a second substrate used for injection with an insulating film formed at a specific spot and by injecting an organic semiconductor film material into the aperture due to capillarity to the aperture. The insulating film formed at the specific spot enables formation of the organic semiconductor film with high controllability. Further, the insulating film can also serve as a spacer that holds the aperture, that is, an interval (gap) between the substrates.

Bacteriorhodopsin protein variants and methods using the bacteriorhodopsin variants for performance in holographic and three-dimensional (3D) memory storage devices are described. The amino acid and chemical modifications of bacteriorhodopsin provided herein achieve greatly enhanced protein performance. The memory storage devices write, read and erase data proficiently. The bacteriorhodopsin protein variants are useful in optical memory storage and associative processor systems.

The variants enter the branched photocycle via a single or a two photon process and form the permanent ‘Q’ state more efficiently than the wild-type bacteriorhodopsin protein. This branching photocycle of the variants is exploited in the fabrication of 3D memory storage devices.

Core-shell particles encapsulated by a thin film of a catalytically active metal are described. The particles are preferably nanoparticles comprising a non-noble core with a noble metal shell which preferably do not include Pt. The non-noble metal-noble metal core-shell nanoparticles are encapsulated by a catalytically active metal which is preferably Pt. The core-shell nanoparticles are preferably formed by prolonged elevated-temperature annealing of nanoparticle alloys in an inert environment. This causes the noble metal component to surface segregate and form an atomically thin shell. The Pt overlayer is formed by a process involving the underpotential deposition of a monolayer of a non-noble metal followed by immersion in a solution comprising a Pt salt. A thin Pt layer forms via the galvanic displacement of non-noble surface atoms by more noble Pt atoms in the salt. The overall process is a robust and cost-efficient method for forming Pt-coated non-noble metal-noble metal core-shell nanoparticles.
