Abstract:
Getter devices with improved sorption rate, based on powders of quaternary alloys particularly suitable for hydrogen and carbon monoxide sorption, are described. Quaternary alloys having a composition comprising zirconium, vanadium, titanium and aluminum as main constituent elements are also described.
Abstract:
An active window containing a Venetian blind made by N slats parallel to each other, wherein the slats comprise an electrochromic active material capable of varying their light throughput by controlling the transmittance and/or reflectance of the slats is described. The width of the slats being between 10% and 95% of a defined distance between two glass panes. The slats may be made of the electrochromic active material or the electrochromic active material may be layered onto the upper layer of the slats.
Abstract:
The present invention refers to a composite getter for thin-film photovoltaic panels which is made with a polymer having low H2O transmission containing one or more alkaline earth metal oxide, to a photovoltaic panel containing such composite getter and to a method for the manufacturing of photovoltaic panels.
Abstract:
The present invention relates to a DSC type solar cell comprising a pair of electrodes serving as anode and cathode, respectively, between which an electrolytic solution is arranged, wherein the anode comprises a supporting member on which a metal oxide layer comprising powders of titanium dioxide and nanozeolites is arranged. The average diameter of the powders of titanium dioxide is comprised between 3 and 30 nm and the average diameter of at least the ten percent of the added powders of nanozeolites is comprised between 200 and 400 am. Thanks to this particular configuration of the anode, the DSC cell of the invention allows to improve to conversion efficiency of the light into electric energy.

Abstract:
A heated alkali metal vapour dispenser comprising a filiform element containing a metal releasing material and two terminals fixed at its ends is described. In particular, metal vapour dispensers with an improved control on the rate and reproducibility of the released metal vapours.
Abstract:
A sensitive device is described including an edge of the sensitive device and a composite material sealing the edge of the sensitive device. The composite material includes a homogeneous dispersion of superficially functionalized nanozeolites in a polymerizable compound. The nanozeolites contain surface modifying organic groups belonging to the same chemical class of at least one functional group of the polymerizable compound.
Abstract:
A carbon dioxide composite getter comprising a CO2-permeable envelope containing powders of two active materials and sealed systems employing the carbon dioxide composite getter.
Abstract:
A getter pump is described. The getter pump has a casing and a getter cartridge mounted within the casing. Each cartridge has a linear central support and spaced getter elements mounted on the linear central support. Each cartridge is positioned along a plane orthogonal to the revolution axis and intersecting the midpoint of a linear central support. The angle formed by each positioning plane with its respective linear central support is comprised between 35° and 75°.
