Abstract: The present invention relates to a method and system for obtaining an interaction property between a molecule or biomolecule or particle or bioparticle or nano- or microparticle on the one hand and a target particle on the other hand. The method comprises obtaining potentiometric titration results for a potentiometric measurement during titration of a solution with a titrant, said solution being a solution of one of a ligand of the target particle or said molecule or biomolecule or particle or bioparticle or nano- or microparticle. Said titrant comprises the other of said target particle ligand or said molecule or biomolecule or particle or bioparticle or nano- or microparticle. The method also comprises deriving based on said potentiometric titration results an interaction property between said molecule or biomolecule or particle or bioparticle or nano- or microparticle and said target particle.

Abstract: Methods use a catalytic composition built up from a ceramic material including a catalytic material and a first inorganic binder and a second inorganic binder and a catalytic structure made thereof. Preferably, the structure is made by a colloidal ceramic shaping technique. The structure is used for catalytic or ion exchange applications. The catalytic structures have excellent mechanical, physicochemical and catalytic properties.

Abstract: A process for the production of a catalyst comprising the steps of: dissolving the requisite quantities of copper nitrate and nickel nitrate in de-ionised water to provide a sub-0.30 molar aqueous solution of copper nitrate and nickel nitrate together in the ratio required; providing an ammoniacal solution by adding concentrated aqueous solution of ammonia in a quantity equal to between six and ten times the quantity required to realise both a 1:6 molar ratio for Cu2+ to ammonia and a 1:6 molar ratio for Ni2+ to ammonia; loading gamma alumina with 1 to 30% w/w of copper and nickel in a weight ratio of nickel to copper of 1:5 to 2:1 by suspending the requisite quantity of gamma alumina in said ammoniacal solution to achieve the required loading of copper and nickel; stirring the resulting gamma alumina suspension for at least 4 h at room temperature; then the volatile components evaporate under ambient conditions leaving dry loaded gamma alumina, which is calcined at a temperature of at least 260° C. for at least 30 min with a constant heating up rate; a catalyst or catalyst mixture, the catalyst or each catalyst in the catalyst mixture being obtainable by the above-mentioned process; and the use of the catalyst or catalyst mixture for the conversion of exhaust gases from an internal combustion engine into carbon dioxide, water and nitrogen.

Abstract: A computer implemented method predicts by a neural network a radio spectrum usage in an environment comprising interferers and a plurality of wireless nodes. The nodes operate via a slotted medium access control, MAC, protocol within a radio spectrum. The method includes the following steps: obtaining per slot the radio spectrum usage by sensing the radio spectrum, labelling the slots as usable when a respective radio spectrum usage is lower than a predefined noise threshold or when a node successfully transmitted a packet through it, unusable when it is not usable and suitable to receive a packet, and calculating a loss function as a cross entropy loss with the usable and unusable slots over a total number of usable and unusable slots, and training the neural network by minimizing the loss function.

Abstract: A wireless communication device comprises a control unit, an antenna interface, an active wireless transceiver operable together with the control unit and antenna interface, a passive wireless transceiver operable together with the antenna interface and operable by harvesting power from received radio messages. The device is further configured to deactivate the one or more active wireless transceivers and control unit to an inactive state and, subsequently, by the passive wireless transceiver, activate the control unit and an active wireless transceiver to an active state when the passive wireless transceiver receives a message from the antenna interface.

Abstract: The present disclosure relates to a method for producing lanthanide doped layered double hydroxides (Ln-doped LDHs). The method includes the steps of preparing a carbonate free alkaline solution; preparing a solution of metal salts comprising a salt of a lanthanide; co-precipitating the alkaline solution and the solution of metal salts to form a mixture and Ln-doped LDH precipitate wherein the pH of the mixture is maintained at a constant value; aging the precipitate; and separating the precipitate from the solution. The alkaline solution is an aqueous ammonia solution. The present disclosure is also related to lanthanide-doped layered double hydroxides (La-doped LDHs) obtainable by such a method, as well as to the use of the lanthanide-doped layered double hydroxides obtainable by such a method.
