A multiple stage web processor including a tensioning stage and a gluing stage. The cylindrical projection is configured to retain a washer on the outside thereof and a fastener on the inside thereof. The silica is then removed from the nanocomposite, e. Core-shell silica particles with an ordered mesoporous layer are produced. At each of the plurality of frequencies, the method may also include determining an efficiency of energy transfer into the object and adjusting power transmitted at each of the plurality of frequencies such that a multiplicative product of the efficiency and the power transmitted is substantially constant across each of the plurality of frequencies.
