Provided is a selective transfer method including depositing a thin film on a substrate; patterning the thin film using a laser or a tool to acquire a thin film of a target pattern; masking the thin film of the target pattern; selectively controlling a surface wettability through surface treatment of the masked thin film; delaminating the thin film of the target pattern by dipping a surface of the thin film with a wettability changed in response to a completion of the selective surface treatment into a liquid material and by applying a crack opening force capable of delaminating an interface between the thin film and the substrate; and immersing a target substrate into the liquid material when the thin film of the target pattern is floating in the liquid material and then scoop-up transferring the floating thin film of the target pattern.

Large scale exploitation of Solar energy is proposed by using floating devices which use solar energy to produce compressed hydrogen by electrolysis of deep sea water. Natural ocean currents are used to allow the devices to gather solar energy in the form of compressed hydrogen from over a large area with minimum energy transportation cost. The proposal uses a combination of well understood technologies, and a preliminary cost analysis shows that the hydrogen produced in this manner would satisfy the ultimate cost targets for hydrogen production and pave the way for carbon free energy economy.

Methods and systems of the present disclosure can function to capture flue gas and convert the flue gas to a synthesis gas, which can be further processed to other components such as liquid fuels. Aspects of the present disclosure provide for a process designed to capture flue gas from large scale (i.e. ˜GW), fossil based power plants in a 24/7 continuous operation. In addition, the method and system can convert the flue gas to a synthesis gas (mainly carbon monoxide and hydrogen), which will be processed into high quality liquid fuels, like diesel.

Processes for producing high biogenic concentration Fischer-Tropsch liquids derived from the organic fraction of municipal solid wastes (MSW) feedstock that contains a relatively high concentration of biogenic carbon (derived from plants) and a relatively low concentration of non-biogenic carbon (derived from fossil sources) wherein the biogenic content of the Fischer-Tropsch liquids is the same as the biogenic content of the feedstock.

The present invention provides a process for producing one or more products for use as a transportation or heating fuel. In various embodiments the process comprises treating a cellulosic feedstock in one or more processing steps that release extractives from the feedstock. A solids-liquid separation is subsequently conducted on the process stream comprising the extractives and solids. An aqueous stream comprising one or more of the extractives may be fed to an anaerobic digester to produce crude biogas from which one or more impurities may optionally be removed. In various embodiments the process further comprises providing a solids stream to a thermal process. A product produced or derived from the thermal process may displace a product made from fossil fuel. One or more products obtained or derived from at least one of the foregoing process steps are provided for use as a transportation or heating fuel. In various embodiments the process enables advantaged fuel credit generation.

A feedstock delivery system transfers a carbonaceous material, such as municipal solid waste, into a product gas generation system. The feedstock delivery system includes a splitter for splitting bulk carbonaceous material into a plurality of carbonaceous material streams. Each stream is processed using a weighing system for gauging the quantity of carbonaceous material, a densification system for forming plugs of carbonaceous material, a de-densification system for breaking up the plugs of carbonaceous material, and a gas and carbonaceous material mixing system for forming a carbonaceous material and gas mixture. A pressure of the mixing gas is reduced prior to mixing with the carbonaceous material, and the carbonaceous material to gas weight ratio is monitored. A transport assembly conveys the carbonaceous material and gas mixture to a first reactor where at least the carbonaceous material within the mixture is subject to thermochemical reactions to form the product gas.

A device and process for the conversion of aromatic compounds, includes/uses: a unit for the separation of the xylenes suitable for treating a cut comprising xylenes and ethylbenzene and producing an extract comprising para-xylene and a raffinate; an isomerization unit suitable for treating the raffinate and producing an isomerate enriched in para-xylene which is sent to a fractionation train; a pyrolysis unit suitable for treating biomass, producing a pyrolysis effluent feeding, at least partially, the feedstock, and producing a pyrolysis gas comprising CO and H.sub.2; a Fischer-Tropsch synthesis reaction section suitable for treating, at least in part, the pyrolysis gas, producing a synthesis effluent sent, at least in part, to the pyrolysis unit.

Described herein are techniques for converting carbonate in a carbonate loaded solution into syngas or C2+ products within an electrolysis cell that includes a cathodic compartment, an anodic compartment and preferably a bipolar membrane separating the compartments. The carbonate ions are converted in situ by reaction with protons generated by the bipolar membrane to produce CO.sub.2 that is in turn electrocatalytically converted into the product. The electrolysis cell can be coupled to an air or flue gas capture system that produces the carbonate loaded solution, and the depleted solution released by the electrolysis cell can be recycled back into the capture system and the feed of the electrolysis cell. The cathode can include a porous substrate that is hydrophilic, and a catalyst metal deposited on the substrate can be Cu, Ag or an alloy depending on the target product.

Described herein is a gaslight multilayered composite tube having a heat transfer coefficient of >500 W/m.sup.2/K which in its construction over the cross section of the wall of the composite tube includes as an inner layer a nonporous monolithic oxide ceramic surrounded by an outer layer of oxidic fiber composite ceramic, where this outer layer has an open porosity of 5%<ε<50%, and which on the inner surface of the composite tube includes a plurality of depressions oriented towards the outer wall of the composite tube. Also described herein is a method of using the multilayered composite tube as a reaction tube for endothermic reactions, jet tubes, flame tubes or rotary tubes.
