    CiteSeerX — Modification of atmospheric DC fields by space

    CiteSeerXDocument Details (Isaac Councill Lee Giles Pradeep Teregowda) Corona ion discharge is responsible for a flux of small ions emanating from an overhead power line capable of modifying the ambient electrical environment. The ensuing space charge can be detected as a change in magnitude of the earth s natural DC electric field at ground level.

    The modification of natural coal by heteroatoms such as N and S or metal oxide species has been demonstrated to form very promising electrocatalysts for the ORR and OER. However it remains elusive and underexplored as to how the impurity elements in coal may impact the electrocatalytic properties of coal-derived catalysts.
