摘要： Ink-based digital printing systems useful for ink printing include a rotatable charge-retentive reimageable surface layer configured to receive a layer of fountain solution. The fountain solution is carried to the charge retentive surface by a fog or mist including fountain solution aerosol particles, dispersed gas particles, and charge directors that impart charge to the fountain solution aerosol particles. The charge-retentive reimageable surface may be charged to a uniform potential, and selectively discharged using an ROS according to image data to form an electrostatic latent image. The charged fountain solution adheres to portions of the charge-retentive reimageable surface according to the electrostatic latent image to form a fountain solution image thereon. The fountain solution image can be partially transferred to an imaging blanket, where the fountain solution image is inked. The resulting ink image may be transferred to a print substrate.

摘要： Ink-based digital printing systems useful for ink printing include a secondary roller having a rotatable reimageable surface layer configured to receive fountain solution. The fountain solution layer is patterned on the secondary roller and then partially transferred to an imaging blanket, where the fountain solution image is inked. The resulting ink image may be transferred to a print substrate. To achieve a very high-resolution (e.g., 1200-dpi, over 900-dpi) print with these secondary roller configurations, an equivalent very high-resolution fountain solution image needs to be transferred from the secondary roller onto the imaging blanket. To increase the resolution of the image on the secondary roller, examples include a textured surface layer added to the secondary roller for contact angle pinning the fountain solution on the roll. Approaches to introduce a micro-structure onto the surface layer of the secondary roller, and also superoleophobic surface coatings are described.

摘要： The disclosure relates to compositions for use in assays, the compositions comprising at least one latent fluorophore including at least one enzyme-reactive quenching group and a conjugative group; and a support connectable to the latent fluorophore by the conjugative group. The disclosure further relates to methods of measuring the presence and/or concentration of an analyte, as well as methods of measuring the relative activity of at least two enzymes.

摘要： Based on evaporation of fountain solution from a rotating blanket cylinder to create an image that may be inked and printed, a digitally addressable heater array at or just below the blanket surface evaporates deposited fountain solution and forms a fountain solution latent image on the surface. The heater array has controllable heating elements (e.g., field effect transistors, thin film transistors) that provide a transient heat pattern on the surface to evaporate the fountain solution. Heat is generated by current flow in the heating elements, and power developed by the heating circuit is the product of source-drain voltage and current in the channel. Current may be supplied along data lines by an external voltage controlled by digital electronics to provide the desired heat at heating elements addressed by a specific gate line. The heater array may include a current return line that may be a 2-dimensional mesh.

摘要： Microorganisms present within a plurality of microorganism clusters immobilized in a porous support material may collectively define a supported bio-catalyst. When the microorganisms are effective to convert methane into one or more oxidized carbon compounds (e.g., methanotrophic bacteria), the supported bio-catalysts may be utilized to remove methane from methane-containing gas streams, such as those obtained from mining ventilation. Methods for processing a methane-containing gas stream may comprise interacting the gas stream with the supported bio-catalyst in substantial absence of a liquid phase, and obtaining a methane-depleted gas stream downstream from the supported bio-catalyst. Systems for processing a methane-containing gas stream may comprise the supported bio-catalysts housed in one or more vessels fluidly coupled to a source of methane-containing gas stream. A gas concentration in the methane-containing gas stream and/or the methane-depleted gas stream may be used to determine a current state or anticipated remaining lifetime of the supported bio-catalyst.
