Water is perhaps the most important and most pervasive chemical on our planet. The
influence of water permeates virtually all areas of biochemical, chemical and physical …

Pyrite is the earth's most abundant sulfide mineral. Its frequent undesirable association with
minerals of economic value such as sphalerite, chalcopyrite and galena, and precious …

Abstract Pyrite (E g= 0.95 eV) is being developed as a solar energy material due to its
environmental compatibility and its very high light absorption coefficient. A compilationof …

Pyrite, FeS2, commonly referred to as “Fool's gold” is the most common sulfide in the Earth's
surface region. Not only is the mineral ubiquitous, but the reactivity of pyrite is of central …

Arsenic and sulphur, and possibly iron, exist in multiple oxidation states in the near-surface
of unoxidized arsenopyrite. X-ray photoelectron spectroscopy (XPS) of an unoxidized …

The mechanism of the initial steps of pyrite (100) surface oxidation was investigated in detail
by means of density functional theory/plane-wave calculations. Pyrite oxidation is related to …

Hydrogen peroxide and hydroxyl radical are readily formed during the oxidation of pyrite
with molecular oxygen over a wide range of pH conditions. However, pretreatment of the …

Samples of natural pyrrhotite and pyrite were fractured within the analytical chamber of an X-
ray photoelectron spectrometer. The pristine mineral surfaces were then exposed, in the …

Iron pyrite has been the material of interest in the solar community due to its optical
properties and abundance. However, the progress is marred due to the lack of control on the …

To investigate the essential difference in the water adsorption on the hydrophobic galena
(PbS) and hydrophilic pyrite (FeS2) surfaces, a single, mono-, and multilayer water …
