Wax Anti-Settling Additives
Wax anti-settling additives (WASA) are used to mitigate against the problems caused by the settling of n-alkane wax crystals, which crystallise from petroleum diesel. This can result in the blocking of fuel filters and hence vehicle failure. However, the mode of action for such additives is not …

Ionisation in Flames with Additives
The addition of phosphorus to a series at atmospheric pressure, of alkalimetal-seeded H2/02/N2 flames results in the formation of negative ions accompanied by a decrease in free electron concentrations. Observations were made of the effects of phosphorus on the ionisation of sodium, potassium, …

The role of additives in Fischer-Tropsch reactions
The Fischer-Tropsch Synthesis (FTS) is an alternative route to produce liquid fuels from a variety of carbon feedstocks including coal and biomass. Typically iron and cobalt based catalysts have been used for the FTS reaction, in which a mixture of CO and H2 (syn-gas) reacts to form hydrocarbons. …

Ionic liquids as additives for biodegradable polyactic acid
In this study, two ionic liquids (IL) with different anions (decanoate, tetrafluoroborate) but with the same phosphonium based cation were evaluated as potential plasticizers and lubricants for polylactic acid (PLA) and also for their effects on its hydrolytic and thermal degradation. Both ILs at …
