The phrase "availability of ions" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly in chemistry or biology, to refer to the presence or concentration of ions in a solution or environment.
Example: "The availability of ions in the soil is crucial for plant growth and nutrient uptake."
Alternatives: "presence of ions" or "concentration of ions".
Therefore, there is a renewed interest in understanding the behavior of the pathogens in different environments of the host like low pH, elevated temperature, changes in osmotic strength, presence of cationic peptides as well as the availability of ions and nutrients.
Compared to amino acids, the change in the availability of ions does not lead to much change in biofilm formation.
However, as the lower availability of ions along with increased pCO2 can impede calcification, photosynthesis and growth of calcifying autotrophs including calcifying macroalgae, reef-building corals and calcifying unicellular plankton are often negatively impacted (reviewed in Kroeker et al. 2010).
The surface water chemistry of streams is considered to be tightly linked to catchment characteristics, with geomorphology determining soil type and availability of ions through weathering (e.g., Allan 1995).
Application of a potential difference between the two aqueous phases and measurement of the transfer current indicate that, for a lipophilic species such as rhodamine B, the transfer is driven in the "out of membrane" direction, due to its high membrane concentration and limited availability of ions in the aqueous phases.
"Another thing that will change is more widespread availability of ion mobility in MS systems," says Carr. Ion mobility helps to separate peptides and proteins from one another in the gas phase to make the sample less complex, which Carr likens to gas phase chromatography.
This could increase the availability of calcium ions and carbonate ions, which are the main reagents for the formation of healing products.
The probable reason for this could be that at lower acidic pH availability of H+ ions are more and Cu II) ions compete with H+ ions for free active sites.
Further, in Lower Cuddalore, the pH decreases due to the exchange of cations in clay/rock matrix with H+ ions in groundwater or the availability of neutralizing ions.
Acidification of the ocean will lessen the availability of carbonate ions in the water, according to the National Oceanic and Atmospheric Administration.
This instance can be attributed to the complete mobilisation of iron through iron oxyhydroxide precipitation and the availability of calcium ions induced by the dissolution of calcium carbonates present on Xiaheyan outcrops during palaeo-weathering.
