Even if the rinsing of fibers prior to weighing was done as thoroughly as reasonably possible, slight residues, barely visible, may have affected the results, i.e. the recorded weight of synthetic fibers.
PCA carves out differences between samples, i.e., even slight residues like sodium sulfate in example 1, a nonperfect self-assembly or marginal differences in signal intensity can be accentuated.
Post-metallization annealing (PMA) was performed at 600°C for 60 s in N2 using rapid thermal annealing so as to remove slight organic residue in oxide stacking and improve the ohmic contact between the electrodes and metal oxide films.
If, for any reason, you don't want the slightest pesticide residue in your salad, or you want to insure that there are no traces of recombinant bovine somatotropin hormone (rbST) in your children's milk, you're better off spending the extra money for organically produced food.
