• #### Destabilization dynamics of clay and acid-free polymers of ferric and magnesium salts in AMD without pH adjustment ﻿

(IWA Publishing, 2016)
The physicochemical treatment was employed to treat acid mine drainage (AMD) in the removal of turbid materials using clay only (exp A) and a combination of clay, FeCl3 and Mg(OH)2 (exp B) to form a polymer. A 5 g sample ...
• #### A detailed calculation of neutral hydrogen ionization frequencies used in turbulence transport models in the heliosphere ﻿

(EDP Sciences, 2015)
It is generally accepted that the solar wind is significantly heated beyond ~10 AU by the turbulent decay of pickup ion generated Alfvénic fluctuations. Here, we present a detailed and general calculation of the pickup ion ...
