Electropermeabilization of nematode eggs for parasite deactivation.

The eggs of parasitic helminth worms are incredibly resilient - possessing the ability to survive changing environmental factors and exposure to chemical treatments - which has restricted the efficacy of wastewater sanitation. This research reports on the effectiveness of electroporation to permeabilize ova of , a helminth surrogate, for parasite deactivation. This technique utilizes electric pulses to increase cell membrane permeability in its conventional application, but herein is used to open pores in nonparasitic nematode eggshells - the first report of such an application to the best knowledge of the authors.

Improved blackwater disinfection using potentiodynamic methods with oxidized boron-doped diamond electrodes.

Electrochemical disinfection (ECD) has become an important blackwater disinfection technology. ECD is a promising solution for the 2 billion people without access to conventional sanitation practices and in areas deficient in basic utilities (e.g.

Enhanced HO Production at Reductive Potentials from Oxidized Boron-Doped Ultrananocrystalline Diamond Electrodes.

This work investigates the surface chemistry of HO generation on a boron-doped ultrananocrystalline diamond (BD-UNCD) electrode. It is motivated by the need to efficiently disinfect liquid waste in resource constrained environments with limited electrical power. X-ray photoelectron spectroscopy was used to identify functional groups on the BD-UNCD electrode surfaces while the electrochemical potentials of generation for these functional groups were determined via cyclic voltammetry, chronocoulometry, and chronoamperometry.
