What does PH in text mean? The abbreviation ph can have different meanings. Its actual meaning depends on the context. For example, in Chemistry, the abbreviation pH means Potential of Hydrogen. It is a measurement scale that defines the nature of a material, like acidic, basic, and neutral...
Because the carboxylic acid group on the amino acid in the enzyme's active site must be in its protonated state, meaning bonded to a hydrogen atom, pepsin works best at pH $1.8$ . The carboxylic acid group is protonated at low pH, allowing it to catalyse the chemical reaction of ...

In particular, the magnitude of the measured adhesion remained higher along most of the pulling rates applied in those experiments where an untreated silicon nitride tip was employed. For a residence time of 0 seconds, meaning immediate retraction upon maximum load achievement, the pulling rate ...
In 1519 ,a silver mine near the town of Joachimstal literally "Joachim’s valley," from the German Tal, meaning valley began minting a silver coin called, unimaginatively, the Joachimstaler. The coin, which was circulated widely, became better known by its clipped form, the taler. In ...
However, when used as raw material, it did not present any catalytic activity, meaning that either graphene oxide does not enhance the production of hydroxyl radicals or it acts as an inhibitor, presenting a higher reaction rate constant with the hydroxyl radicals and, hence, scavenging them. ...
On the other hand, irradiance values lower than 0.18 W·cm−2 were not considered since the photonic efficiency decreased, meaning lower NAP oxidation. 2.2. Effect of Goethite Concentration The decrease of NAP was studied in the absence of the catalyst and using 0.1 and 0.2 g·L−1g·L...
The meaning of AMORPHIZATION is the act or process of making something structurally amorphous or of becoming structurally amorphous. How to use amorphization in a sentence.
These variables are coupled, meaning variations in one immediately cause changes in others. In addition, the effect of these variables on electrochemical behavior appears to be interrelated. This research work evaluates the influence of a number of environmental variables on the corrosion behavior of ...
It should also be understood that, unless a term is expressly defined in this patent using the sentence "As used herein, the term ' ' is hereby defined to mean..." or a similar sentence, there is no intent to limit the meaning of that term, either expressly or by implication, beyond...
