The present invention provides a method for producing a magnetic nanoparticle-coated laminate material. The method comprises coating a pair of opposed surfaces of a plurality of steel or iron/cobalt (Fe/Co) alloy film portions with a magnetic nanoparticle-containing coating. Each magnetic nanoparticle comprises a core and a shell covering at least a portion of the core. The shell and core are made of different materials selected from one or more of: iron, cobalt, nickel; and/or alloys comprising two or more of: iron, cobalt and/or nickel; and/or magnetic rare earth metals; and/or diamagnetic transition metals. The method further comprises stacking the coated film portions on top of each other such that a or each coated surface of each film portion is located adjacent a further coated surface of an adjacent film portion; and compressing the stacked coated film portions together to form a nanoparticle-coated laminate material.

The invention relates to a low-pressure coating system and a method for coating particle or fibre collectives by means of physical or chemical vapour phase deposition. A deagglomeration unit is used, by means of which the particle or fibre collective is separated and then coated. These particles are used for example as active material for batteries and capacitors and as 3D printing powder or colour pigments. The fibres are used for example for textiles, membranes, filters or composite materials.

Systems and methods electronic barcoding of particles. The methods comprise: performing operations by a spin coater to spin coat a single layer of particles onto a substrate; performing operations by a heat applicator to apply heat to the substrate so as to evaporate a liquid; and performing operations by at least one material depositor to transform the particles into Electronically Barcoded Particles (“EBPs”). EBPs are fabricated by: coating a portion of each said particle of the particles with a first conductive layer; depositing an insulative layer on the first conductive layer; and/or depositing a second conductive layer on the insulative layer so as to form a parallel plate capacitor on the particle. The parallel plate capacitor is tuned so that the particle has a capacitance that is different than the capacitances of other ones of the electronically barcoded particles.

A method of applying a homogenous film coating to a constituent particle of component includes setting up a target element in a sputtering chamber. The method also includes arranging a receptacle in the sputtering chamber. The method additionally includes arranging the constituent particle on the receptacle. The method also includes bombarding the target element via energetic particles to eject material from the target element and deposit the material onto the constituent particle. The method further includes agitating the receptacle during the bombarding to apply the material to the constituent particle as the homogenous film coating. The method may be used to apply a homogenous thin film coating to a sulfur-infused constituent particle for a sulfur cathode in a lithium-sulfur battery.

The present invention relates to a pigment mixture based on at least two components A and B, where component A is a mixture of flake-form and spherical substrates which is covered with one or more inorganic layers and/or organic layers, and component B comprises crystalline or amorphous particles selected from the group of the metal oxides, metal hydroxides, metal oxy-halides, Prussian Blue or mixtures thereof,

and to the use thereof in paints, coatings, printing inks, security printing inks, plastics, ceramic materials, glasses, in cosmetic formulations, as tracer, as filler and for the preparation of pigment preparations and dry preparations.

The present application relates to fiber cloth having functional composite particles and a preparation method therefor. The preparation method comprises: placing a solid metal block consisting of functional metal particles into a crucible using an evaporation and condensation process, and heating and evaporating the same into a vacuum physical vapor deposition (PVD) process furnace for condensation; depositing PVD ceramic layers on the outer surfaces of the functional metal particles under the condensed state using a PVD process to form the functional composite particles; and screening the functional composite particles by means of a particle filter and accelerating the particles to bombard the fiber cloth, thereby implanting the functional composite particles into the fiber cloth to form the fiber cloth having the functional composite particles. The functional composite particles in the present application can reduce contact between the internal functional metal particles and external oxygen, slowly release ionic metal ions of the functional metal particles, and prolong the action time of the functional metal particles. According to the present application, by implanting the functional composite particles into the fiber cloth, the fiber cloth with a long lasting antibacterial effect can be obtained.

In an example, a device cover may comprise a substrate and a metal luster layer having a lustrous paint formulation applied to an outer surface of the substrate. The lustrous paint formulation may comprise base particles with surfaces partially coated with metal nanoparticles. The metal nanoparticles may be disposed in a non-continuous manner on the base particles.

The present disclosure provides an impregnation method that includes the steps of providing a workpiece to be impregnated, placing the workpiece in a bath of impregnating agent inside a vessel, and oscillating movement of a vibrating body inside the vessel during an impregnation period. The vibrating body creates oscillating pressure changes inside the bath by acting on the bath. the method further includes removing the workpiece from the bath after the impregnation period.
