Provided is an apparatus for preparing an aerogel blanket, the apparatus comprising: a bobbin around which a blanket is wound; a body provided with a gelling tank in which the bobbin is accommodated; a driving member configured to allow the bobbin accommodated in the gelling tank to rotate; and a silica sol supply member configured to gelate the blanket as silica sol is injected into the gelling tank to impregnate the blanket rotating by the bobbin.

A superhydrophilic thick-film pH sensor based on chemical etching, and a preparation method thereof are provided. The superhydrophilic thick-film pH sensor includes: a substrate, and a working electrode and a reference electrode that cover surfaces of the substrate. The working electrode includes a titanium sheet attached to one side of the substrate; a front part of an outer surface of the titanium sheet is covered with a titanium dioxide sensitive layer; an electrically-conductive layer is attached to the other side of the substrate; the reference electrode is located on the electrically-conductive layer, and a surface of the reference electrode is coated with a naphthol layer; and an insulating gel wraps the substrate to expose only the working electrode and the reference electrode. The working electrode is obtained by soaking the titanium sheet in an 80? C. NaOH solution, and is integrated with the reference electrode to produce the thick-film pH sensor.

A heat generating system comprises two or more thermal reactors. During operation, a first thermal reactor is pressurized while a second thermal reactor is depressurized to vent unused gas and byproduct. The unused gas and byproduct from the second reactor are separated in a gas separator and the unused gas is supplied to the first reactor while the first reactor is pressurized. An exothermic reaction is triggered in the first reactor, which results in generation of heat and byproduct cluster formation. When the exothermic reaction is complete, the process is reversed and the second thermal reactor is pressurized while the first reactor is depressurized.

The present invention relates to an installation for the production of dihydrogen comprising: a reaction enclosure (1) intended to contain an oxidizable material, an alkaline solution feed system (2) fluidly connected to the reaction enclosure (1), a pure water (31) supply system (3) fluidly connected to the reaction enclosure (1), a dihydrogen collection system (4) downstream of the reaction enclosure (1), the collection system (4) being fluidly connected: to the reaction enclosure (1), to the supply system (3), and to a storage receptacle (5) configured to store the produced dihydrogen at a desired high pressure.

A modular device for generating hydrogen gas from a hydrogen liquid carrier may include a housing; an inlet for receiving the hydrogen liquid carrier; and at least one cartridge arranged within the housing. The cartridge may include at least one catalyst configured to cause a release of hydrogen gas when exposed to the hydrogen liquid carrier. The modular device may include a gas outlet for expelling the hydrogen gas released in the modular device and a liquid outlet for expelling spent hydrogen liquid carrier.

A method for chemically destroying magnetic data carriers. Recorded data are irretrievably eliminated and cannot be re-read. The carriers include aluminium or its alloys and ferromagnetic materials. They undergo a digestion reaction with an aqueous solution of a digesting mixture including: a) hydrochloric acid and (V)nitrate of one or more alkali metals, alkaline earth metals, rare earth metals and ammonium; or b) nitric(V) acid and chloride of one or more alkali metals, alkaline earth metals, rare earth metals and ammonium. The product of the reaction is an aqueous solution having aluminium hydroxide and chlorides and (V)nitrates of metals contained in the ferromagnetic metals and gaseous products of the reaction. Acidic salt solutions are utilized in a sewage treatment plant. Gaseous products including hydrogen and nitrogen oxides, after diluting with nitrogen, are directed to the atmosphere through an absorption system.
