Graphene is a material with unique properties that can be exploited in electronics, catalysis, energy, and bio-related fields. Although, for maximal utilization of this material, high-quality graphene is required at both the growth process and after transfer of the graphene film to the application-compatible substrate. Chemical vapor deposition (CVD) is an important method for growing high-quality graphene on non-technological substrates (as, metal substrates, e.g., copper foil). Thus, there are also considerable efforts toward the efficient and non-damaging transfer of quality of graphene on to technologically relevant materials and systems. In this review article, a range of graphene current transfer techniques are reviewed from the standpoint of their impact on contamination control and structural integrity preservation of the as-produced graphene. In addition, their scalability, cost- and time-effectiveness are discussed. We summarize with a perspective on the transfer challenges, alternative options and future developments toward graphene technology.

Due to strong impacts of rockbursts in ostrava-Karvina coalfield which affect especially roadways and cross-cuts of longwall panels it is necessary to strengthen standard steel roadways *** in rockburst prone areas the high proportion of rockbursts in break-throughs is *** to the statistics 19%of all rockbursts in ostrava Karvina coal basin in the period 1993 2003 occurred in break-throughs in spite the fact that their total length is less than 10%of the total summary of developed roadways.((?)up(?)rek 2005).Break-throughs as starting space of longwall faces play an important role in application of new mining *** of efficient longwall equipments needs large width of the cross cuts which reflects in demands on their support. The effective adaptations of steel support for underground roadways in areas with rockburst danger had to be based on the knowledge of behaviour of the support for the most frequent ways that the dynamic loads acted on *** analysis of rockburst manifestations in roadways showed that the prevailing impact on the support comes from the coal *** of all,they are more or less horizontal side impacts,mostly from the future coal panel *** from the floor also occurred in gates situated in thick seams under the roof.
