A method and a system are for compensating optical aberrations in a telescope. An automatic transaction apparatus comprises: an upper unit provided with a bill depositwithdrawal part and a sorting part ; and a lower unit comprising denomination-specific cassettes and a reject storage part. A respective wafer lift structure on each carrier is moveable between first and second positions, with the wafer supported spaced away from the heat sink and in thermal contact with the heat sink respectively. , to obtain a self-seeding polyalkylthiophene solution; and applying the self-seeding polyalkylthiophene solution obtained in step to one surface of a nano-template having a hydrophobic supramolecule coating layer formed thereon to induce self-assembly and crystallization of polyalkylthiophene on the surface. The contact assembly is held within the central opening. In order to accommodate the higher pressures when operating as a turbine, a suitable refrigerant is chosen such that the pressures and temperatures are maintained within established limits.
