since the surface water is one of the main potable water resources, the usage of chlorine as a disinfectant has increased. consequently the production rate of disinfection by-products (dbps) such as trihalomethane (thm) compounds has grown dramatically. in this paper the thms concentration changes in the sangar water treatment plant (swtp) and rasht water distribution system (rwds) is presented...

The atomic-scale characterization of surface active sites on γ-alumina still represents a great challenge for numerous catalytic applications. Here, we combine advanced density functional theory (DFT) calculations with one- and two-dimensional proton solid-state NMR experiments to identify the exact location spatial proximity hydroxyl groups crystallites. Our approach relies revisited models (1...

A new one-pot electrophilic chlorination and bromination with oxidative demethylation uses harmless inexpensive sodium chloride bromide Oxone to yield alicyclic ring-fused bis-benzimidazolequinones.
