Abstract: Mixtures are provided of lithium salts with reducing agents for lithium evaporation. The mixtures may be particularly used in the manufacture of electroluminescent organic displays. Lithium dispensers based on the use of these mixtures are also provided.

Abstract: Magnesium-copper compositions are used for the evaporation of magnesium and container up to 43.34% by weight magnesium.

Abstract: A gas sorbing system is formed by gas sorbing components which are dispersed in a polymeric matrix which is porous or permeable to the gases to be sorbed. The gas sorbing components include a central nucleus, selected among a silica particle, polyhedral oligomeric silsesquioxane and a spherosilicate, to which there are bound at least one organic or metalorganic radical carrying a functional group, which is able to chemically fix the gas to be sorbed, and at least one anchoring organic radical including a chain of carbon atoms, which has the functionality of fixing the nucleus in the matrix polymer.

Abstract: Getter systems are provided including one or more deposits of getter materials, wherein at least one of the deposits is in contact with a layer of a material having H2O transport properties.

Abstract: Getter systems are provided having a phase being active in the sorption of gas inserted in the pores of a porous material. The porous material is, in turn, dispersed in a polymeric means that is permeable to the gas to be sorbed.

Abstract: Getter systems are provided having a phase active in the sorption of gas, inserted in the pores of a porous material. The porous material is, in turn, dispersed in a polymeric means having a low permeability to the gas to be sorbed.

Abstract: Mixtures are provided of lithium salts with reducing agents for lithium evaporation. The mixtures may be particularly used in the manufacture of electroluminescent organic displays. Lithium dispensers based on the use of these mixtures are also provided.

Abstract: A dispensing system is provided for alkali metals, that allows increasing the quantity of alkali metal that can be dispensed, as well as the time during which the system can be used with properties of metal vapors release which are constant over time. The system includes an alkali metal dispenser, the dispenser being a metallic container having one or more first openings and containing a mixture of one or more alkali metal compounds and one or more reducing compounds, preferably in the form of loose powders or pellets of the powders. The system further includes a metallic shield which substantially encloses the container and has one or more second openings facing the first openings.

Abstract: Compositions and devices for gas sorption are provided that can be activated just before their use, which hence do not need storing under inert atmosphere during storage and transportation.

Abstract: An accessory member for alkali metals dispensers is provided in the form of a screen (30; 40; 60) of substantially tubular shape, one end (34; 44; 64) of which can be applied to an alkali metals dispenser (10). The cross-section of the one end is superposable to an entire alkali metals emission zone (14) of the dispenser (10). The contact portion between the one end (34, 44; 64) and the dispenser (10) is made with a low thermal conductivity material. The screen (30; 40; 60) is provided with an internal surface having a high specific area.

Abstract: Cesium mixtures are produced based on the use of a mixture of at least one reducing agent and at least one cesium compound selected among molybdate, tungstate, niobate, tantalate, silicate and zirconate. The cesium mixtures are useful in the production of OLED-type screens.

Abstract: Cesium dispensers based on the use of a mixture between a reducing agent and a cesium compound selected among molibdate, tungstate, niobate, tantalate, silicate and zirconate are described. Some processes for the use of these dispensers are also described.

Abstract: Systems capable of converting water into reducing gases are described. These systems can be employed in moisture sensitive electronic and microelectronic devices, whose functioning is not influenced by the contact with reducing gases; in particular, the systems according to the invention can be used in the screens, known as OLEDs, containing electroluminescent organic materials.
