Microbial photoproduction of n-heptane [PDF]

Biofuel Research Journal
The photoenzyme fatty acid photodecarboxylase (FAP) has emerged as a promising catalyst for the redox-neutral biological production of hydrocarbons. Previous studies have shown that FAP can efficiently convert medium-chain fatty acids such as n-octanoic ...

Dynamic viscosity and refractive index of aliphatic n-heptane with substituted aromatic hydrocarbons at T = (303.15 to 323.15) K and atmospheric pressure

Chemical Thermodynamics and Thermal Analysis
Dynamic viscosity and refractive index of aliphatic n-heptane with substituted aromatic hydrocarbons, such as toluene, o-xylene, and mesitylene were measured at T = (303.15 to 323.15) K and atmospheric pressure. The measurements were carried out over the
