Marine crude-oil biodegradation: a central role for interspecies interactions [PDF]

, 2012
The marine environment is highly susceptible to pollution by petroleum, and so it is important to understand how microorganisms degrade hydrocarbons, and thereby mitigate ecosystem damage. Our understanding about the ecology, physiology, biochemistry and

3D and 2D aromatic units behave like oil and water in the case of benzocarborane derivatives

Nature Communications, 2022
2D/2D fusion of aromatic halves leading to a global aromatic is found in many polycyclic aromatic hydrocarbons, whereas 2D/3D aromaticity is difficult to achieve. Here the authors report a computational chemistry investigation showing that 3D/2D aromatic
