It is essential to design and develop new technologies for wastewater treatment and water recovery. Bromophenols (BPs) are widely used as flame retardants (brominated flame retardants

The normalized concentration of bromide ions (with DBMP degradation efficiency close to 95%; Figure 7) is about 0.9 (where 1 is the theoretical complete release of

Release yields of bromine in the form of bromide ions as high as 90% showed eventual mineralization. The half-live of DBMP in photocatalytic

We have recently reported on similar behavior in the case of brominated alkoxybenzenes where a brick-wall type structure was ascribed to a

Contrast enhancement signals of 40 HU were observed in the liver of imaged animals [14]. Two hours after injection, micelles loaded with
