Sphingomonadaceae are also known by the ability of some species to degrade some aromatic compounds.
Hückel's rule, a method of determining aromaticity in organic molecules
Kuhn's areas of study included: investigations of theoretical problems of organic chemistry (stereochemistry of aliphatic and aromatic compounds; syntheses of polyenes and cumulenes; constitution and colour; the acidity of hydrocarbons), as well as extensive fields in biochemistry (carotenoids; flavins; vitamins and enzymes).
"Sprayed On","Sprayed In","Spray On", "Spray In" (these terms are used interchangeably in the industry) come in two classes of material and two main types of application processes: aromatic and aliphatic compounds applied through a Low pressure (not heated) or high pressure (heated) process.
