摘要： The invention is a negative charge director for liquid electrographic toners. The charge director comprises a very weakly associating, charged functional group covalently bonded in the resin coating of the toner particle, and a very strongly chelating, preferably neutrally charged, molecule dispersed in the liquid phase to achieve charge separation. The weak association site on the resin is prepared, via well-known ion-exchange chemistry, in the metal form desired. Preferred metals are those with no regulatory, health or environmental issues, such as K+, Na+, Ca.sup.2+, Al.sup.3+, Zn.sup.2+, Zr.sup.4+, Mg.sup.2+, ammonium (NH.sub.4 +), and organic cations.The cation-associated resin is brought into dispersion with the solution phase chelating molecule. When this is done, the equilibria that compete for the cation are such that it is released from the resin and bound in the chelate. The toner particle is left with a net negative charge which is permanent, but which is balanced by an equal, opposite charge on the chelated cationic species in the continuous phase. Preferably, there are no other sources of charge in the dispersion, and there is no excess of charge carriers in the continuous phase which would interfere with development.

摘要： Switching devices (10) comprise a micro-electrode (12 or 16a') coated with a templated polymer (14). For example, the template molecule is glucose and the bulk polymer is a thiophene/boronic acid-substituted thiophene copolymer. The switch is activated or inactivated by the concentration of glucose in a solution (38) contacting the coated micro-electrode. Advantageously, the dimensions of the switch may be very small, 10.sup.-6 or less.

摘要： A method of electrochemical deposition uses microdroplets of electrolytic solution over a targeted small circuit element. Only the targeted circuit element is electrically biased so that deposition occurs on the surface of that element, underneath the microdroplet, and nowhere else unless it is under other microdroplet(s). The invented method achieves extremely accurate and selective electrochemical deposition with a tiny amount of electrolytic solution, compared to conventional submersive and/or immersive methods, and eliminates the need for masking or etching, reducing the costs of manufacture and amount of waste electrolytic solution produced.

摘要： The present invention is an apparatus for laboratory and field use in detecting and measuring Hg+ and Hg2+ in sample. A selective mercury binding agent, such as a chelating agent or clathrating agent, is covalently bound in a copolymer and deposited as an electrode layer. To prepare the preferred apparatus of the invention, thiophene, or other, similar monomer, is derivatized by covalent attachment thereto of Kryptofix-21™ (1,4,10-trioxa-7,13-diazacyclopentadecane) in the 3-position. The thiophene monomer and Kryptofix-21™ are co-polymerized and electrodeposited by known techniques onto a conductive substrate, such as platinum or glassy carbon, to obtain a multi-layer polymer coating of desired thickness. The resulting coated electrode has selective coordination sites for mercury of the order of Kf=1016, compared to Kf=103 for cadmium, Kf=105 for lead and Kf=105 for silver. Therefore, the resulting probe is very selective for mercury, compared to cadmium, lead and silver.

摘要： A system and method for electrophotographic printing an image with a plurality of toners, where the plurality of toners includes toners that are attracted to either a first charge potential or a second charge potential. The electrophotographic system includes a photoconductive surface that is charged to the second charge potential. A laser selectively discharges the photoconductive surface to the first charge potential in accordance the image to be printed. Those toners that are attracted to the first charge potential are applied to the photoconductive surface, wherein the toners are electrostatically attracted to those areas of the photoconductive surface that are at the first charge potential. The photoconductive surface again charged to the second charge potential. The photoconductive surface is again discharged to the first charge potential in accordance with those areas of the image to which those toners that are attracted to the second charge potential are to be repelled. Those toners that are attracted to the second charge potential are applied to the photoconductive surface, wherein the toners are electrostatically attracted to those areas of the photoconductive surface that remain at the first charge potential. Finally, the image is transferred to a receiving surface.

摘要： Disclosed are negatively and positively charged liquid toners for electrophotography (EP). The charge on the toner particle is obtained by adding cage complex molecules, or clathrates/cryptates, to the liquid toner. The cage complex molecules have at least three chains, with at least one electron pair donor atom in each chain, for a total of at least three electron pair donor atoms (EPD's). Or, the cage complex molecules have at least two connected rings, with a total of at least three EPD's in the molecule including at least one EPD in each of the connected rings. For negatively charged toner particles, the clathrates/cryptates are distributed in the liquid dispersion, and metal cations are weakly associated with anionic functional groups on the toner particle. This way, the clathrates/cryptates in dispersion complex selectively with the cations and strip them from the toner particle, leaving a negatively charged particle. For positively charged toner particles, the clathrates/cryptates are covalently bound to the toner particles, and weakly associated metal cations are added with corresponding anionic species to the liquid dispersion. This way, the clathrates/cryptates on the toner particles complex selectively with the cations, and strip them from the dispersion, creating a positively charged particle.
