The article focuses on the potential of building a space elevator using lightweight and ultra-strong materials such as single crystal graphene, hexagonal boron nitride, or carbon nanotubes. Topics include the need for a tether material with high tensile strength to support the elevator, the challenges of manufacturing such materials on an industrial scale, and the progress being made in producing graphene as a viable candidate for the space elevator tether.

A case study of the development of a knowledge management system in a chemical company of medium size is presented. The effectiveness and use of this system are examined and problems such as employees' attitudes are explored.
