The role of Moringa oleifera in the development of alternative biofuels, under the concept of an integral one‐tree biorefinery: A minireview

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The Moringa oleifera oil tree is commonly known as the ‘tree of life’ or the ‘miracle tree’ owing to its multiple benefits for humans. The different parts that make up this tree (leaves, seeds and bark) have been used to treat various ailments, diseases and wounds. However, in recent years this tree is being used by the scientific community to

Heat Transfer Prediction for Methane in Regenerative Cooling Channels with Neural Networks [PDF]

open access: yes, 2019
Methane is considered being a good choice as a propellant for future reusable launch systems. However, the heat transfer prediction for supercritical methane flowing in cooling channels of a regeneratively cooled combustion chamber is challenging. Because accurate heat transfer predictions are essential to design reliable and efficient cooling systems,

A novel decision support system for designing and assessing phytoremediation‐to‐biofuel value chains

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The design of biofuel value chains is a complex process due to the large number of stakeholders involved, seasonality in feedstock availability, security of supply, logistics costs, efficiency considerations, and its multi‐node nature. Decisions on designing phytoremediation‐to‐biofuel value chains are even more complicated, due to the ...
