摘要： Methods are disclosed for producing an organic functionalized solid inorganic substrate, a surface of the inorganic substrate comprising a hydroxide and/or an oxide comprising an element M, the element M being a metal or a metalloid. The method includes drying the surface; optionally removing protons from the surface; and contacting the surface with an organometallic reagent comprising at least one organic functional moiety, thereby obtaining the organic functionalized inorganic substrate, the at least one organic functional moiety being attached to the element M of the hydroxide and/or the oxide by means of a direct M-C bond. The drying step includes contacting the surface with a flow comprising an inert gas. The organic functionalized inorganic substrate obtained by the method may be used as a membrane, a catalyst, a sorbent, a sensor or an electronic component, or as a substrate in filtration, adsorption, chromatography and/or separation processes.

摘要： A method is disclosed for applying a protective layer on at least part of an exposed alkali metal or alkali metal alloy substrate. The method includes activating a gas using a plasma discharge to obtain an activated gas and contacting the exposed surface with the activated gas. A protective layer is formed on at least part of the exposed surface. The gas has a nitrogen-comprising compound such that the protective layer includes at least 60 mol % of a corresponding alkali metal nitrate. The present disclosure is further related to an article including a substrate having a surface including an alkali metal or alkali metal alloy and a protective layer arranged on at least part of the alkali metal or alkali metal alloy surface of the substrate.

摘要： A method and system for manufacturing three-dimensional porous structures. Filaments are deposited in a predetermined interconnected arrangement in a plurality of stacked layers for forming a porous structure with interconnected pores. Furthermore, the porous structure is subjected to a heat treatment in a heat chamber in order to reduce a moisture, solvent and/or organic material, solvent or organic material content (drying and/or calcination) of the porous structure by irradiating microwave energy through said porous structure. The applied microwave energy is selected based on the structural interconnected arrangement of the deposited filaments defining the shape and size of the pores of the three-dimensional porous structure.

摘要： A method and system for printing a three-dimensional porous structure (1). Interconnected filaments (2) are deposited in a predetermined arrangement in a plurality of stacked layers (11). The filaments (2) of the consecutive layers (11) are connected to one another to obtain the porous structure (1) with interconnected pores (15). The filaments are deposited in such a way that one or more preselected frangible regions (7) are formed in the arrangement of filaments (2). The one or more frangible regions (7) are connected to less-frangible regions (9) of the porous structure (1). The predetermined arrangement of interconnected filaments (2) is configured such that the one or more frangible regions (7) form structurally weakened zones of the porous structure (1) such that the porous structure (1) breaks along said one or more frangible regions (7) under influence of a load and/or a stress. The plurality of three- dimensional parts (10a) are releasable under influence of the load and/or stress.

摘要： An assembly includes a housing with opposite first and second layers. The first and second layers are spaced apart to define a confined interior space. A semi-permeable membrane is attached to the first layer, the semi-permeable membrane covering a porous area portion of the first layer. An outlet port and an inlet port are in fluid communication with the interior space. The assembly includes a first circulator for circulating a first fluid between the outlet port and the inlet port, and a second circulator for circulating a second fluid along an exterior surface of the semi-permeable membrane. The second circulator includes a fluid duct attached to or integrated within the housing. The fluid duct is isolated from the interior space and is porous to provide fluid access to an exterior surface of the semi-permeable membrane. The semi-permeable membrane forms a barrier allowing exchange of compounds across the membrane.

摘要： A method is disclosed for the generation of hydrogen and oxygen from a liquid feed stream comprising water. The method includes passing an electric current through an aqueous electrolyte solution. Water is fed to the aqueous electrolyte solution by forward osmosis, wherein the aqueous electrolyte solution is brought into contact with a first side of a forward osmosis membrane and the liquid feed stream comprising water is brought into contact with a second side of the forward osmosis membrane. Water permeates through the forward osmosis membrane from the second side to the first side by a difference in osmotic pressure between the liquid feed stream and the aqueous electrolyte solution. Further, a device is disclosed for carrying out the above method.

摘要： A method and system for performing characterization of one or more materials. One or more materials are scanned by means of a sensory system including an X-ray sensor configured to perform multi-energy imaging for obtaining at least a lower-energy X-ray image and a higher-energy X-ray image. Images obtained by means of the sensory system are segmented, and for each segmented object, data indicative of an area density and data indicative of an atom number by analysis of the lower-energy X-ray image and the higher-energy X-ray image, and data indicative of the area density and atom number is determined by means of a calibrated model. Data indicative of a mass is calculated based on the data indicative of the area density and the data indicative of the area of each of the segmented objects. The data indicative of the atom number is provided as input to a trained neural network, wherein the trained neural network is configured to label each segmented object, and wherein the data indicative of the mass is coupled to each of the labeled segmented objects.

摘要： A hybrid battery charger-testing device is described being a modification of a battery charger having a DC output stage, and a boost converter added to the DC output stage of the charger, the boost converter being configured to output pulses and/or a continuous AC wave for testing a battery. The hybrid charger can be used to output a purely AC test wave, e.g. sinusoidal wave for an electrochemical impedance spectroscopy test, to output pulses such as HPPC pulses and/or to perform GITT or incremental charge tests. For example, determination of battery parameters by diagnostic testing can be achieved by combining the existing functionality of a battery charger with test procedures involving currents much lower than used during charging of the battery or of returning battery energy to the electricity grid.

摘要： A method for producing a porous carbon electrode includes preparing a slurry by mixing a porous, particulate, conductive carbon powder with a solution of a polymer binding agent for the particulate carbon powder in a solvent for the polymer binding agent, forming a precursor electrode by casting the slurry as a layer and subjecting the cast layer to a wet phase inversion to realize porosity in the cast layer, subjecting the thus obtained precursor electrode to a thermal treatment to cause oxidative stabilization, carbonization, dehydrogenation or cyclisation of the polymer binding agent or a combination of two or more of the afore mentioned phenomena by heating the precursor electrode and converting the polymer binding agent into a conductive binding agent binding the particles of the conductive carbon powder together.
