Abstract:
An aqueous dispersion of ethylene-vinyl alcohol copolymers suitable to be used as lacquer to realize a thin coating both for flexible or rigid substrates, characterized by excellent oxygen and carbon dioxide barrier performances especially under high humidity conditions. The dispersion comprises a first ethylene-vinyl alcohol copolymer in the form of capsules with an ethylene content comprised between 24 and 38 mol % and a second ethylene-vinyl alcohol copolymer with an ethylene content lower than 15 mol %.
Abstract:
The present invention relates to cathodes electrodes compositions suitable to provide a pumping mechanism which exhibits an extremely high pumping speed and capacity of noble gas suitable to be used in several vacuum devices as for example sputter ion vacuum pumping systems comprising them as active element.
Abstract:
The present invention relates to a heat shielding composite cloth (100) comprising at least one pair of layers (11, 12) movably connected to each other by one or more Shape Memory Alloy (SMA) wires (103). The invention also relates to garments incorporating such heat shielding composite cloth (100).
Abstract:
A dispensable chemical composition comprising a blend of siloxane polymeric components, with a low viscosity component in an amount greater than a high viscosity component, and suitable to integrate a high amount of filler materials while maintaining rheological features of thixotropic index and viscosity values at low and high shear rates proper for a dispensing paste.
Abstract:
LED system comprising a sealed internal volume containing one or more elements sensitive to the presence of Volatile Organic Compounds (VOCs), wherein in said internal volume is present a getter composition for VOCs removal comprising a combination of at least two different types of zeolite.
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 composite transparent lighting device is described. The device has a transparent substrate, an uniform distribution of low concentration dielectric particles, reflective perimeter and perimetral discrete light sources, of improved appearance both in the inoperative state of the device, and at the same time capable of providing good quality lighting when the device is active, i.e. when the discrete light sources on the perimeter of the device are turned on.
Abstract:
A getter pumping system for linear accelerators or high-volume environments, is described. A plurality of getter cartridges having a linear support and a plurality of linear heaters are connected in a high-density configuration to a wall that has a surface area of at least 0.5 m2.
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:
Sails for sailboat wind propulsion comprising shape memory systems containing shape memory elements are described. The shape memory systems are arranged in correspondence to the sail battens, extending along them and operably connected to the sail opposite faces or directly to the battens so as to face the opposite faces of the sail. A control apparatus and method of said sails is also described.
