a) Remove the caps from both ends of the silica gel SPE cartridges and attach the SPE cartridges to the stopcocks on a 16-position glass block manifold. Add 10 mL of n-hexane IMMEDIATELY into the ...

The composition of petroleum is a complex mixture of hundreds of different hydrocarbon compounds. The resultant makeup of hydrocarbons released into the environment is variable, and dependent on the ...

For the past 20 years, polycyclic aromatic hydrocarbon (PAH) molecules have commonly been considered the carriers of unidentified infrared emission (UIE) features. This hypothesis assumes that the UIE ...

While many chemistries have been developed to incite C–H bonds to react, certain types of aliphatics stubbornly resist such transformations. Now, chemists at Princeton University and Merck & Co. have ...

Methods for selective oxidation of aliphatic C–H bonds are called on to revolutionize organic synthesis by providing novel and more efficient paths. Realization of this goal requires the discovery of ...

Nearly all polymers are derived from nonrenewable fossil resources, and their disposal at their end of use presents significant environmental problems. Nonetheless, polymers are ubiquitous, key ...
