A water supply borehole in the Sherwood Sandstone aquifer in Warrington, UK was found to be infested with iron bacteria that resulted in large ochreous deposits and damaged the pump. Before the pump was replaced, the borehole was treated using hydrogen peroxide. Comparison of the borehole ...
(Chemistry) potential of hydrogen; a measure of the acidity or alkalinity of a solution equal to the common logarithm of the reciprocal of the concentration of hydrogen ions in moles per cubic decimetre of solution. Pure water has a pH of 7, acid solutions have a pH less than 7, and alk...
The team proposed a strategy using lunar soil to electrolyze water from the moon and the astronauts' life support system into oxygen and hydrogen. The process is powered by sunlight. The carbon dioxide exhaled by moon inhabitants can be collected and combined with hydrogen to yield the fuel me...

Oxidation-reduction potential (ORP) is a measurement that determines water’s oxidizing or reducing potential, quantifying a solution’s electron transfer capacity. ORP is valuable for assessing the presence of oxidizing or reducing agents, such as oxyge
the computed hydrogen electrode. On the basis of this structural model, we investigated the water oxidation mechanism (Figure 4) starting from the H2O-Co(II)-(μ-Ο)2-Co(III)-OH2 intermediates (I). We note that our computational method overestimates the oxidation potential of Co(III) to ...

For a long time, hydrogen sulfide (H2S) has been considered a toxic compound, but recent studies have found that H2S is the third gaseous signaling molecule which plays a vital role in physiological and pathological conditions. Currently, a large number of studies have shown that H2S mediates ...
