In the strictest sense, not all means of expressing the composition of a solution or mixture fall under the simple term "concentration". Some sourcesonlyconsider mass concentration, molar concentration, number concentration, and volume concentration to be true units of concentration. Concentration Versu...

the dissolution of natural minerals in the rocks and soils creates the formation of fluoride when it interacts with water. High fluoride concentrations can be built up in groundwaters, which have long residence times in the host aquifers. In addition to the natural means of getting fluoride, the...

This means that adatoms diffuse crossing many atomistic steps before incorporation. 23.2.2 Detection of Nucleation The finding of RHEED intensity oscillations has opened the possibility of detecting two-dimensional (2D) nucleation in real time in MBE. Before the discovery of the RHEED oscillations, ...
In this section, we will focus on the antibacterial activities of the Cu NPs. The antibacterial activities of the five Cu NPs (A–E) prepared using various concentrations of NaOH solutions (2, 4, 6, 8 and 10 mol·L−1) were investigated by means of S. aureus and E. coli bacteria,...
