Sample preparation. The structure of CoPOM and ZnPOM have been previously reported. The complexes used in this work have been synthesized using the procedure described for the analogous MnII compound but using Co(SO4) and Zn(SO4) instead of Mn(SO4). HiPCo SWNTs were purchased from Carbon Inc. and purified by the gas phase method. All the solutions were prepared using Millipore water. Functional...
متن کاملNew technique of sample preparation for respirometry of filamentous fungi.
Various difficulties in the respirometry of filamentous fungi were avoided by using samples of moist mycelium layered thinly on tantalum grids. A variety of measurements is feasible with such preparations and are illustrated with samples of Schizophyllum commune from liquid and solid cultures.
