Biogenic polyamines, such as putrescine, spermidine, and spermine are small organic polycations involved in numerous diverse biological processes. These compounds play an important role in nucleic acid function due to their binding to DNA and RNA. It has been shown that biogenic polyamines cause DNA condensation and aggregation similar to that of inorganic cobalt(III)hexamine cation, which has ...

Tannin polyphenols are produced by plants to protect themselves against natural decay. It is expected that impregnating low-durable timber with tannin extracts of more durable species such as quebracho (Schinopsis balansae) will enhance the durability specimens. This biomimetic approach combined in situ polymerization quebracho–hexamine formulations can be a valid alternative synthetic wood pre...

Crystal structures of Thermotoga maritima magnesium transporter CorA, reported in 2006, revealed its homo-pentameric constructions. However, the structure of the highly conserved extracellular interhelical loops remains unsolved, due to its high flexibility. We have explored the configurations of the loops through extensive replica exchange molecular dynamics simulations in explicit solvent mod...

Chemical kinetics, also known as reaction kinetics, is the study of chemical processes’ rates. Chemical kinetics includes investigations into how different experimental conditions can influence the speed of a chemical reaction, and yield information about the reaction's mechanism and transitional states, as well as the construction of mathematical models that can describe the characteristics of...
