Silver is a fairly rare element in the Earth's crust. Its abundance is estimated to be about 0.1 parts per million. It is also found in seawater. Its abundance there is thought to be about 0.01 parts per million. Silver usually occurs in association with other metal ores, especially thos...
When a chemical element is translated into Chinese, the character usually contains a radical that indicates the physical properties of the element according to the Chinese philosophy of nature. This idea dates back to the year 1871. For example, the term argon was translated into ya with an air...
Models of kerogens belonging to the three classical Types have been represented at the following evolution stages: • -beginning of diagenesis (sensu-stricto), • -beginning of catagenesis, • -end of catagenesis. Chemical models are drawn, using analytical data obtaine...
“the same place”. so the idea behind using this name is that isotope variants of a single element are found in the same position on the periodic table. the term was first used by margaret todd, a scottish doctor, and writer while consulting with radiochemist frederick soddy. this term ...
Abbreviations and compound labels like "COOH" and "Ph", as well as formulae can be expanded to quickly build and work with complex chemical structures. You can define your own custom abbreviations to be used in ChemDoodle. Custom Element Color Sets ...
Our data also provide insights into the structure and dynamics of a conserved mobile sequence beginning with a ‘PDPC(+)’ motif that plays a key role in metazoan CCD membrane binding and enzymatic function. The importance of this sequence was proposed in a paper describing the cloning of RPE...
