Wrong Citations

A few frequently cited values of PZCs/IEPs have actually never been published. Namely, they have been cited after secondary sources, without checking the primary source, which reports different PZCs/IEPs than that in a secondary source, a result of limited significance, or no PZCs/IEPs at all. Reference [2469] is quoted in [1] and then by a few other authors (probably after [1]) as an authoritative source of the IEP of hematite. Actually, no specific IEP is reported in [2469]. The authors mention that pH 2.4-4.2 is far from the IEP, but they do not specify how far. 

References [3039,3040] are cited in [1] as a source of PZC of silica. Actually it is only speculated in [3040] that a maximum in gelation time may coincide with the point of zero charge, and in [3039] PZC is not mentioned at aU. 

Reference [3041] is cited in [1] as a source of the PZC of iron oxide. Actually, [3041] reports previously published data on anion- and cation-exchange capacities of various oxides. The results from [3042] are cited in [1] as IEP at pH 3 obtained by electrophoresis. Actually, the streaming potential was used in [3042], and the pH was not controlled or reported. All samples of quartz, also acid-treated, showed negative potentials in the presence of various electrolytes. 

Results from [3043] were cited in [1], and then quoted after [1] in numerous papers. Inspection of the original paper reveals that the quality of pristine PZCs/ lEPs derived from the results presented in [3043] is limited. Table 1 reports equilibrium pH of aqueous suspensions of four oxides, apparently containing occluded acid or base and/or multivalent ions. Eigure 1 shows a titration curve with no data points between pH 5 and 9. Eigure 2 shows uptake of monovalent ions by two oxides as a function of pH. The uptake is not a monotonic function of pH, and there are very few data points in the vicinity of the PZC.

Strike got the journal article for this recipe as literature citation used in the original Wacker oxidation Strike used for Method 2. In it both mercuric acetate, and to an extent, lead acetate produced ketones as described. Someone-Who-ls-Not-Strike also got a certain ketone. But maybe they were lucky or just plain wrong. Most people on Strike s site say this mercuric acetate thing... 

Receiving OSHA citations can propel your safety culture development in the wrong direction. Your workers are interested in working in a hazard-free environment. Once a citation is received, team members may have less confidence or trust in management s judgment. This lack of confidence can take years to mend, and in the meantime culture suffers.
