Abstract: Granules of graphene oxide may be produced from a dispersion of nanoscale graphene oxide sheets by a spray drying method. Such granules have a three-dimensional corrugated morphology. The complexity of the corrugations, and the size distribution of the granules can be varied through selection of the spray-drying equipment used, and variation of the composition of the dispersion and the spray-drying parameters. Structural modifiers may be included in the graphene oxide dispersion to control the ultimate morphology of the granules. The granules of graphene oxide may be thermally reduced at a moderate temperature of 220° C. to increase the granules' electrical conductivity. The reduced granules may be used to fabricate electrodes for supercapacitors. The power and energy density of such an electrode material is comparable to those of conventional/commercial activated carbon-based electrodes.

Abstract: A method of adaptively positioning a scanner [10] within a three-dimensional scene identifies an optimal next position for the scanner [40] based on analysis of a data point cloud that mimics the scanned portion of the scene.

The fourth coordinate corresponds to the hue observed by the scanner at each data point.

Abstract: A film for the retention and controlled release of organic or inorganic molecules consists essentially of a phyllosilicate clay and a organic polyanion. The film may be a built-up layered film of alternating layers of the clay and the polyanion. Organic or inorganic molecules are absorbed into the film from solution, and released in response to changes in the film's environment. The film may be built up using layer-by-layer (LbL) methods, or deposited on a substrate from a mixture of the clay and polyanion. Articles may be coated with the film by the same methods. The film is useful for the controlled release of antibiotics in response to infections, and also retains antibiotics such that bacteria may be killed by direct contact with the film.

Abstract: Monatomic metal anions are generated in the gas phase by collision-induced dissociation of the anions [26] of a dicarboxylic acid salt of the metal. This method is applicable to a number of metals, including sodium, potassium, cesium, and silver. The metal anions produced in this way can subsequently be stored in an ion trap [88] or transmitted as a focused beam [52]. The metal anions of this invention undergo collisional cooling and have low kinetic energy, which distinguishes them from ions produced by other high energy processes (with kinetic energy in excess of 1 keV). Metal anions so produced can be used to pattern nanoscale features on surfaces [56], used as electron transfer agents or reducing agents in ion-molecule reactions, or used for surface [122] modification of biomaterials [124].

Abstract: A goniometer has three potentiometers with axes of rotation that intersect at a point for measuring angular range of motion of an anatomy, such as of the spine or jointed appendages. The intersecting axes facilitate calculation of angle based on potentiometer output and allow the rotations on each of the three axes to be measured independently and simultaneously without mechanical or electrical cross talk. The angular measurements may be recorded on a computer for analysis and playback and may be continuously captured over a range of motion. The captured data may be compared to samples from the same person or others to aid in assessment of function.

Abstract: An electrical component includes an inkjet-printed graphene electrode. Graphene oxide flakes are deposited on a substrate in a graphene oxide ink using an inkjet printer. The deposited graphene oxide is thermally reduced to graphene. The electrical properties of the electrode are comparable to those of electrodes made using activated carbon, carbon nanotubes or graphene made by other methods. The electrical properties of the graphene electrodes may be tailored by adding nanoparticles of other materials to the ink to serve as conductivity enhancers, spacers, or to confer pseudocapacitance. Inkjet-printing can be used to make graphene electrodes of a desired thickness in preselected patterns. Inkjet printing can be used to make highly-transparent graphene electrodes. Inkjet-printed graphene electrodes may be used to fabricate double-layer capacitors that store energy by nanoscale charge separation at the electrode-electrolyte interface (i.e., “supercapacitors”).
