A rotor cap for an electric generator, e.g., a high-speed turbogenerator, is disclosed, along with a production method for such rotor cap. The rotor cap is at least partially made of fiber-reinforced plastic material. The rotor cap may have cooling fluid passages, e.g., extending in an axial direction, in the area of the fiber-reinforced plastic material.

A method for encapsulating an optoelectronic component by depositing a diffusion barrier for protection against environmental influences by means of an atmospheric pressure plasma on at least one subarea of the surface of the optoelectronic component.

Encapsulated optoelectronic component and method for the production thereof

A superconducting coil for a magnetic resonance apparatus is formed by one or more wound superconducting conductors that are embedded in a cured sealing compound, with a filler composed only of nanoparticles added to the sealing compound.

An electrical insulation paper that is made of mica flakelets (), having an average size range of 0.01 to 0.05 mm in their thinnest dimension, hexagonal boron nitride (), which has an average size range of 10 to 1,000 nm in their longest dimension, and a resin matrix. The mica flakelets and the hexagonal boron nitride are mixed and formed into a paper (), and the resin is added to the paper after formation, the ratio by weight of the hexagonal boron nitride to the mica flakelets is directly proportional to the average size of the hexagonal boron nitride compared to the average size of the mica flakelets, within an adjustment factor.
