Commercially available dip strips based on peroxidase technology are widely used to semiquantitatively determine the peroxide concentration in peroxidizable solvents. However, on the basis of the results of our study, the method can only qualitatively respond to limited types of peroxides; it also responds to other oxidants, such as NaClO. Therefore, test results obtained from dip strips should be used for reference only. Differential scanning calorimetry is recommended as a more reliable and direct method to assess decomposition risks.

Novel cages based on acetone complex with dimeric units of calix[4]arene dimethoxycarboxylic acid extend along different directions to form polymeric cages, and the polymers interlock to form layer arrays, that in turn antiparallel pack in a bilayer architecture.
