Air, pressure, heat, corrosive agents, and other factors encountered by a lubricant during use can cause chemical changes in the oil. Changes in the oil chemistry can have a negative impact on the ...

WHILE nitrous acid (we include in this term all material that with water gives nitrous acid) is a negative catalyst in aromatic nitration generally, it has often been found to be a positive catalyst ...

Figure 1: The nos gene is upstream of characterized thaxtomin biosynthetic genes. Figure 2: Deletion of nos decreases thaxtomin production by S. turgidiscabies. Figure 3: Nitrite formation from N ...

Researchers have developed the first synthetic method to make proteins with nitrated versions of tyrosine in specific sites. The method may make it easier to study how α-synuclein, a protein ...

An in-service lubricant encounters heat, air, corrosive agents, pressure, and other factors that cause chemical changes in the oil. Changes in oil chemistry can also impact the lubricant’s ability to ...
