A wrench compatible for use in limited access areas is made up of two components. A first CaS inlet 40 and a first CaSO4 inlet 64 are also defined by the reducer reactor 12. The invention also provides a method for statically displaying sub-regions of this large digital image at different magnifications, together with a reduced magnification macro-image of the entire sample. Aligned arrays of these carbon nanomaterials are prepared by filtering the nanomaterials with ethanol.
