Abstract:
A method is provided for producing a visual hydrogen sensor and to a sensor produced in this manner, the sensor allowing the presence of hydrogen gas in a medium to be detected by the naked eye as a result of a change of colour in the sensor. The method involves the deposition of thin porous layers of oxides that do not absorb visible light in their completely oxidised state which become coloured when they are partially reduced. This deposition is carried out using vapour phase deposition (PVD) in a glancing angle configuration (GLAD). The method also involves the preparation of a solution of an active metal precursor capable of dissociating the hydrogen molecule and a carrier vector and the deposition of this solution on the oxide layer in order to incorporate a minimum quantity of active metal within the pores of the oxide layer in the form of nanoparticles.
Abstract:
Hybrid plant with a combined solar-gas cycle and operating method with two circuits, one air circuit and one steam circuit, the air circuit having a gas turbine with an intercooler with a natural gas supply, and the steam circuit having a steam turbine and storage systems. The steam circuit can have steam or salt solar receiver. Said plant can work more reliably by reducing the working temperature of the air in the receiver.
Abstract:
The present invention relates to the procedure for the preparation of barrier and/or dielectric layers on a substrate, characterized in that it comprises the following stages: (a) cleaning the substrate, (b) placing the substrate on a sample holder and the introduction thereof into a vacuum chamber, (c) dosage of said vacuum chamber with an inert gas and a reactive gas, (d) injection into the vacuum chamber of a volatile precursor that has at least one cation of the compound to be deposited, (e) activation of a radio frequency source and activation of at least one magnetron, (f) decomposition of the volatile precursor using plasma, the reaction between the cation of the volatile precursor and the reactive gas occurring at the same time that the reaction between the reactive gas contained in the plasma and the cation from the target by sputtering takes place, thus leading to the deposition of the film onto the substrate. The device for carrying out said method is also object of the invention.
Abstract:
The invention relates to a configuration of the receivers in concentrated solar plants with towers comprising at least one medium-temperature receiver (3) and one high-temperature receiver (4) in which each high-temperature receiver (4) is located above and slightly in front of each medium-temperature receiver (3), such that a portion of the rays that bounce off the medium-temperature receiver (3) heats the rear portion of the high-temperature receiver (4) and in which the high-temperature receiver (4) is positioned such that the majority of the surface thereof is opposite the wall of the cavity (2), only the bottom portion of the receiver (4) remaining free.
Abstract:
The present invention describes a method for the preparation of graphene or graphenic material films by the carbonization of biopolymers.The method comprises the following stages: preparation of an aqueous solution of a non-crystallizable water-soluble biopolymer or a derivative of said biopolymer at the suitable pH, coating of the substrate with the aqueous solution of the biopolymer prepared in the previous stage by immersion of the substrate in said solution or by using the spin coating technique, conditioning of the aqueous solution of the biopolymer by means of a hydrothermal process consisting of subjecting the coated surface to a flow of nitrogen saturated with water vapor at the temperature of between 100 and 250° C. for a time between 30 minutes and several hours, thermal decomposition of the biopolymer deposited on the substrate in the absence of oxygen at temperatures below 1200° C.
Abstract:
Spectrophotometer for the characterisation of receivers of solar collectors in order to determine optical properties (transmittance and reflectance). The equipment allows the evaluation of a receiver tube in real time and in any kind of light conditions, both inside and outside. The equipment also allows the detection of the eccentricity between the outer tube and the inner tube, which directly influences the reliability of the measurement. The equipment has a mechanical system for allowing a rotation of the equipment around the tube in order to find the optimum measurement position and attach itself to the tube.
