Extraction and analysis of the hydrocarbons from European honey bee queens indicates the presence of unsaturated compounds not exhibited by worker bees. Queen-specific hydrocarbons consist of a ...

Gas phase enthalpies of formation at 298.15 and 1 atm (Δ~f~H~(g),298K~) were calculated using the atomization approach at the G4MP2 composite method level of theory for 86 polyaromatic hydrocarbons ...

Hydrocarbons are the Organic compounds obtained by the simple combination of hydrogen and carbon-like petrol, diesel, and kerosene oil, etc. It is usually divided into two categories: Aliphatic ...

An alkene, olefin or olefine is a class of highly reactive unsaturated hydrocarbons, recovered from petroleum, with at least one carbon-carbon double bond. What are the olefins? An alkene, olefin or ...

Dendralene hydrocarbons have a reputation for being difficult — it seemed that these molecules couldn't easily be made. A practical synthesis of dendralenes opens them up for study, and reveals some ...

A research team led by Associate Professor Boon Siang Yeo from the Department of Chemistry at National University of Singapore (NUS) has developed a new way to turn carbon dioxide, a greenhouse gas, ...

The second homologous series is the alkenes. Their names all end in –ene, for example ethene. Alkenes all contain a carbon to carbon double bond which makes them more reactive than the alkanes. The ...

Chemists from the National University of Singapore (NUS) have developed a new way to turn carbon dioxide, a greenhouse gas, into valuable liquid hydrocarbons, which are the main components of fuels ...
