Abstract: A printing method includes forming an image by applying marking material onto the surface of a substrate; optionally applying an intermediate layer onto the substrate; subjecting the image to a fixation treatment; applying a layer of an ionically stabilized varnish on the surface of the image; and performing image-wise gloss control by locally varying at least one of a fixation parameter and a primer application parameter.

Abstract: The present invention relates to a method for applying an image onto the recording medium, the method including the step of applying a primer composition comprising a stoichiometric polyelectrolyte complex to a recording medium. The present invention further relates to a printing apparatus for carrying out said method.

Abstract: Enhanced oil recovery becomes increasingly important in satisfying the growing demand for fossil fuel. The efficiency of secondary recovery processes like water flooding is however largely influenced by the rock characteristics, fluid characteristics, chemistry and physics. For development of the full potential of secondary oil recovery, it remains a challenge to obtain sufficient knowledge about the reservoir conditions. The present invention provides a novel water-dispersed, nano-sensor composition based on. InP/ZnS quantum dots (“QDs”) and atomic silver clusters, which exhibit a bright visible fluorescence combined with dedicated sensor functionalities. The QD and silver nano-sensors were tested in simulated reservoir conditions to determine their selected functionality to these reservoir conditions. The developed nano-sensors showed improved sensor functionalities towards pH, temperature, and subterranean reservoir rock, such, as clay or limestone.
