Some recent results on the synthesis of coiled carbon nanotubes (CNTs) are summarized. Several supported catalysts can lead to the formation of coiled CNTs. Interestingly, certain domains of the coil pitch and coil diameter are favoured, and two “stability islands”are found in the 3D representation of the number of coiled CNTs as a function of both coil pitch and coil diameter. It is emphasized that these nanotubes are formed either by introducing pairs of five-membered ring - seven-membered ring or by forming haeckelite structures. The coiled CNTs could be used in nanocomposite reinforcement as well as special sensors based on their remarkable mechanical and electrical properties.

The more precise modeling of transformers, taking into account also wave propagation along their coils is now even more necessary because of the increasing level of electromagnetic noises on electric networks and the even higher switching frequency of power supply units built into sensible electronic devices. For a reliable forecast through simulation of the reaction transformers to incoming over-voltages and other interference a quasi-distributed parameter model has been proposed for one-layer straight coils. Some aspects for finding the optimum lump number is investigated in this paper.
