    摘要： Imaging processes where charge images are transferred from one surface to another are improved by the presence of conductivity sites on at least one of the surfaces, said sites being discrete, composed of an inorganic material, and having an average length between 1.0 and 20 nm. Between 0.1 and 40% of either the photoconductive surface or dielectric layer may be covered with electrically conductive sites.

    摘要： Heat-triggered colorants for altering the color of a food, methods for changing the color of a food using heat-triggered colorants, and methods for making heat-triggered colorants for food. The heat-triggered colorants may comprise a mixture comprising a carrier having a melting point and a GRAS (Generally Recognized as Safe) first food colorant having a color, and a coating encapsulating the mixture and masking the color of the first food colorant. When the heat-triggered colorant is exposed to a temperature greater than the melting point of the carrier, the carrier melts and releases the first food colorant, thereby unmasking the color of the first food colorant.

    摘要： A method forms self-sustaining particles that comprise a hydrophobic (oleophilic) phase in particulate form, with no need for a rigid shell to encapsulate the phase, and usually with no shell present. The oleophilic phase contains a gelation agent, and preferably an organogelation agent. The particles may be stored alone or in a minor amount (e.g., less than 40% by volume) of water to assist their stability and act as a barrier against their coalescence. These water-separated compositions are not necessarily dispersions or suspensions, but may be merely particles in an aqueous storage environment. The particles have prolonged stability and can be readily, simply, and inexpensively formed. A simple method of manufacture comprises forming a solution of the ingredients (e.g., at least the oleophilic material and gelation agent) at a temperature above their gelation temperature, forming droplets or molten, or liquid or flowable particles of the solutions, and cooling the droplets to form the particulates. Cooling may be effected by exposure to ambient conditions (e.g., room temperature) when the ingredients are properly selected, or an actual cooling environment may be needed.

    摘要： A process and apparatus collects pigment nanoparticles by forming a vapor of a pigment that is solid at room temperature, the vapor of the pigment being provided in an inert gaseous carrying medium. At least some of the pigment is solidified within the gaseous stream. The gaseous stream and pigment material is moved in a gaseous carrying environment into or through a dry mechanical pumping system. While the particles are within the dry mechanical pumping system or after the nanoparticles have moved through the dry pumping system, the pigment material and nanoparticles are contacted with an inert liquid collecting medium.
