Recyclable soluble polyisobutylene-bound oxidizing agents

Evaluating the Effectiveness of Topical Oxidizing Agents

• Methods: Case series data were analyzed from 66 failing periodontal maintenance patients who had exhausted treatment options before using prescription trays with a 1.7% hydrogen peroxide gel once or twice daily for two-and-a-half to five years. Data included pocket probing depths (PPD), bleeding on probing (BOP), smoking status, and compliance with tray usage. Data were collected prior to tra...

Investigating the Effect of Various Oxidizing Agents on the Surface Functionalization of Microporous Polypropylene Membranes

The reaction of metmyoglobin with strong oxidizing agents.

In our previous papers (George & Irvine, 1951, 1952, 1953a) we showed that the intermediate compound, which is formed when metmyoglobin (MetMb) reacts with hydrogen peroxide, methyl or ethyl hydroperoxide, may be considered as one in which the iron has an effective oxidation number of + 4. Its relationship to MetMb, represented by Fep3+(H20), is given by the equation, Fep3+(H20) = FepI' + e , w...

Efficient oxidizing agents for determination of 2,10-disubstituted phenothiazines.

2,10-Disubstituted phenothiazines are the best drugs in psychiatry. Several methods for their analysis have been reported in the literature. The official methods are based on non-aqueous titration or spectrophotometry. Various oxidizing agents have been used for the spectrophotometric determination of 2,10-disubstituted phenothiazines, e.g. Ce(SO4)2, NH4VO3, K2S208, KIO4, KIO3, KBrO3, FeCl3, Na...

Intermediate length scale dynamics of polyisobutylene.

We report on a neutron spin echo investigation of the intermediate scale dynamics of polyisobutylene studying both the self-motion and the collective motion. The momentum transfer (Q) dependences of the self-correlation times are found to follow a Q(-2/beta) law in agreement with the picture of Gaussian dynamics. In the full Q range of observation, their temperature dependence is weaker than th...
