Aqueous pigment dispersions

Abstract: Disclosed herein are aqueous dispersions comprising: at least one pigment present in an amount of at least 10% by weight relative to the total weight of the dispersion, the at least one pigment being selected from oxidized carbon blacks and modified carbon blacks having attached at least one organic group; and at least one organic solvent present in an amount of at least 10% by weight relative to the total weight of the dispersion, the at least one organic solvent having a Hansen hydrogen bonding parameter (δ H ) ranging from 13 to 50 MPa 0.5 , and a Hansen polarity parameter (δ p ) ranging from 5 to 13 MPa 0.5 , wherein the dispersion is substantially free of a surfactant. Also disclosed are methods of preparing aqueous dispersions and injet ink compositions prepared from the same.

Method for making a film from silver-containing particles

Abstract: Provided are silver-containing powders and a method and apparatus for manufacturing the silver-containing particles of high quality, of a small size and narrow size distribution. An aerosol is generated from liquid feed and sent to a furnace, where liquid in droplets in the aerosol is vaporized to permit formation of the desired particles, which are then collected in a particle collector. The aerosol generation involves preparation of a high quality aerosol, with a narrow droplet size distribution, with close control over droplet size and with a high droplet loading suitable for commercial applications.

Process for printing features with smaller dimensions

Abstract: The invention relates generally to a printing process. In particular, the invention relates to a printing process where a first-printed feature or vanishing trace causes a second-printed feature to have a smaller dimension than it would in the absence of the first-printed feature or vanishing trace.

Use of aerogels as adsorption agents

Abstract: According to a first liquid purification method, the liquids to be purified are brought into contact with the aerogels from a liquid phase acting as adsorption agents during a time period which is long enough to enable adsorption of impurities contained in the liquids. In a second liquid or gas purification method, the gases or liquids to be purified are brought into contact with hydrophobized aerogels acting as adsorption agents during a time period which is long enough to enable adsorption of impurities contained in the gases or liquids.

Method and apparatus for separating fine particles

Abstract: A method for separating fine particles from contaminant particles suspended in a gaseous medium. The method includes introducing a particle suspension at a predetermined velocity into a vessel having a top and bottom portion, each portion having a discharge outlet. The particle suspension is then directed into an impingement plate, which is arranged within the vessel at a predetermined angle. The impingement plate is angled to achieve uniform distribution of the particle suspension within the vessel after impact with the plate. The fine particles will rise to the top portion of the vessel, and the contaminant, as well as residual fine particles, will settle to the bottom of the vessel. The fine particles and contaminant and residual fine particles are removed from the top and bottom discharge outlets respectively.
