The symbols are abbreviations of the origins of the word for each element. For example, the origin of lead's symbol, Pb, is the Latin word 'plumbum' meaning 'liquid silver'. The number above the symbol is the atomic mass (or atomic weight). This is the total number of protons and neutrons in an atom.

Titratable Acidity (TA) Measures the sum of hydrogen ions free or attached; it does not measure the total acidity (all acid anions). 40 Titratable Acidity TA TA is determined by titration with a base to an endpoint of pH (phenolphthalein) it is then expressed as grams/100ml or grams/liter (g/L) of tartaric acid.

When tea leaves are processed, the chemical compounds within them break down, form complexes with one another and form new compounds. When steeping tea leaves, our senses are tingled by the thousands of volatile compounds (collectively known as the "aroma complex") rising from the tea liquor and the thousands of nonvolatile compounds that are floating within the tea liquor.

Chemical shifts are included for strong photoelectron lines, the common Augerelectron lines, and Auger parameters. A leading plus or minus sign on the chemical shift energy is required. The designation begins with CS, followed by the symbol for a photoelectron line, an Auger line, or an Auger parameter,, CS2p3 for CS2p 3/2, CSL355G for CSL 3 M 45 M 45 ( 1 G), and CS,AP2p3,L3 for CS,AP2p 3/2,L 3 M 45 .
Tantalum is sputtered either as a pure metal, or as a nitride in reactive sputtering. There are two benefits to this. The first is that the purity of the sputter target material is maintained in the deposited film and second, the process is much easier to control than chemical vapour deposition (CVD).
