Abstract: According to a first aspect of the invention, a method for producing a metal-CNT composite material is proposed. The method includes providing a layer of CNT by depositing CNT coated with a polyphenol or poly(catecholamine) coating and filling the interstices of the carbon nanotubes layer with a metal so as to form a metal matrix, in which CNT are embedded. The filling is effected by electrode position or by electroless deposition. The polyphenol or poly(catecholamine) coating is crosslinked by metal ions, the metal ions promoting, as metal seeds, adhesion and/or growth of the metal matrix during the filling step. A further aspect of the invention relates to the metal-CNT composite obtainable by the method.

Abstract: A magnetic sector including magnetic means, a yoke including a first magnetic portion, and a deflection gap in the first magnetic portion. The magnetic sector is configured such that the magnetic means are adapted for generating a magnetic field through the deflection gap in order to deflect charged particles moving in the deflection gap. The yoke further includes a second magnetic portion having a magnetic shunt including a shunt passage for the charged particles. The magnetic shunt directs a magnetic flux leaked from the deflection gap into the first magnetic portion.

Abstract: The disclosure relates to core-shell nanoparticle, the nanoparticle comprising a core being one or more selected from vaterite, proto-vaterite, and amorphous calcium carbonate as determined by X-Ray diffraction, remarkable in that the nanoparticle further comprises a shell of polyphenol, wherein said polyphenol is selected to be insoluble in water, to show a pH ranging from 5 to 9 when measured in a solution of one or more polar solvents and water at a concentration of 10 wt. % based on the total weight of said solution and wherein said polyphenol is at least partially soluble in said one or more polar solvents. A method for forming such nanoparticle as well as their use and the use of polyphenol as shell of shell-core nanoparticle is also described.

Abstract: A system configured for producing electric power from sea waves. The system includes a buoyant body; an electric generator including an input shaft adapted to rotate with respect to the buoyant body; a first arm coupled to the electric generator; a second arm; and a pivot joint rotatably joining the second arm to the first arm, said arm. The pivot joint is at a distance, along the first arm, from the input shaft. The first arm connects the second arm to the generator. The tandem arms form a double pendulum system powering an autonomous floating sea analysing station.
