The screening and treatment of acid mine drainage (AMD) using Na2FeO4 was explored. Elemental composition performed, an Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) for the raw treated AMD. AMD samples were collected from three different sampling sites:(Raw Tailing Water 1 (RTW1), Raw 2 (RTW2) 3 (RTW3)) in Pretoria, South Africa, with acidic pH ranging between 2.50 3.13. T...

Removal of nine pharmaceutical compounds--acetaminophen (AAF), antipyrine (ANT), caffeine (CAF), carbamazepine (CRB), diclofenac (DCF), hydrochlorothiazide (HCT), ketorolac (KET), metoprolol (MET) and sulfamethoxazole (SMX)-spiked in a primary sedimentation effluent of a municipal wastewater has been studied with sequential aerobic biological and ozone advanced oxidation systems. Combinations o...

ZnO and SnO2-doped ZnO nanoparticles were prepared by a sol–gel method for the first time. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to characterize the ZnO and SnO2-doped ZnO samples. Advanced oxidation processes (AOPs) have proved very effective in treatment of the various hazardous organic pollutants such as surfactants and pharmaceuticals...

Force microscopy enables a variety of approaches to manipulate and/or modify surfaces. Few of those methods have evolved into advanced probe-based lithographies. Oxidation scanning probe lithography (o-SPL) is the only lithography that enables the direct and resist-less nanoscale patterning of a large variety of materials, from metals to semiconductors; from self-assembled monolayers to biomole...
