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...

2.1 Chemistry of boron in water Boron species are found predominantly in aqueous solutions, depending on the boron concentration, pH, and temperature of the solution (e.g., boric acid, which is a very weak Lewis acid (Eq. (1)) and its conjugate base (B(OH)−4) at a low boron conc...
Prompted by these challenges, a number of ingenious approaches have been developed over the last years to measure ER Ca(2+) by optical means. The two main strategies used to date are Ca(2+)-sensitive synthetic dyes trapped into organelles and genetically encoded probes, based either on 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, ...
The system includes an absorber which mixes sample liquid with gaseous base, means for pressurizing the reference electrode, and an analyzer cell which prevents contamination of the measuring electrode with reference fluid leaking from the reference electrode. A separate reservoir mixes known ...
The apparatus according to the invention comprises two support rollers (4, 5) having parallel axes and carried by a base (1), and a displaceable support roller (20) carried by the base (1), with means (27) for holding and positioning a probe (32) with respect to the article to be ...
