The small "p" stands for "the power of," and together the two letters are short for "the negative logarithm of thehydrogen-ionconcentration." Alternatively, the formula is written as follows: Do you really know what pH is? (Technical Briefs) ...

Here, we developed and validated a liquid chromatography- mass spectrometry (LC-MS/MS) method for the determination of hydrogen sulfide in various biological matrices by determination of a derivative of hydrogen sulfide and monobromobimane named sulfide dibimane (SDB). 36S-labeled SDB was ...
Then the demagnetization correction for a perfect diamagnet (magnetic susceptibility χ = −1) can be written as follows: $$\frac{\triangle M}{{HV}}=-\frac{1}{1-N},$$ (2) where V is the volume of a sample. The absolute value of ΔM, the difference in M between a ...
The resulting Vop value can therefore be written as follows:8where I is the cell current, Re and Rcathode/anode are the resistances of the electrolyte and electrodes respectively and η is the overpotential at the two electrodes. Currently, AEM and SOC electrolysers are very much in research...
— Robert Boyle, Tracts written by the Honourable Robert Boyle containing new experiments, touching the relation betwixt flame and air... The word "sulfureous" may be somewhat confusing, especially since Boyle did a similar experiment with iron and sulfuric acid.[75] However, in all likelihood...
The proportion of renewable energy which is stored and transformed to available energy is the product of overall processing energy transfer ratios as written in Equation (8) and Equation (9). To achieve the maximization of energy utilization, a high energy transformation ratio of close to 80 ...
The sealing process did not change the states of Pd, Ag and O, although an X-ray photoelectron spectroscopic (XPS) signal of sulfide was found. At the same time, the sealing process led to an increase in concentration of carbon and sulfur contaminants in the surface layer, resulting in a...
Thus, the hydrogen molecule, the oxygen molecule, and the nitrogen molecule would be written H-H, O=O, and N\??\N. Organic molecular structure When the scientists tracked the pattern of emissions of a particular hydrogen molecule consisting of three hydrogen atoms (rather than the usual two...
Recently, monolayer molybdenum disulphide (MoS2) has emerged as a promising and non–precious electrocatalyst for hydrogen evolution reaction. However, its performance is largely limited by the low density and poor reactivity of active sites within its b
