Rubber Seed Oil-Based UV-Curable Polyurethane Acrylate Resins for Digital Light Processing (DLP) 3D Printing

open access: yesMolecules, 2021
Novel UV-curable polyurethane acrylate (PUA) resins were developed from rubber seed oil (RSO). Firstly, hydroxylated rubber seed oil (HRSO) was prepared via an alcoholysis reaction of RSO with glycerol, and then HRSO was reacted with isophorone ...

Synthesis of biodiesel from waste oil by glycerol pre-esterification

open access: yesEnergy Reports, 2023
The waste oil with high acid value was used as raw material, and compared the pre-esterification of methanol and glycerol. The results showed that methanol pre-esterification can reduce the acid value to below 4 mgKOH/g only by multiple chemical ...

Boreal forest biomass classification with TanDEM-X [PDF]

open access: yes, 2012
High spatial resolution X-band interferometric SAR data from the TanDEM-X, in the operational DEM generation mode, are sensitive to forest structure and can therefore be used for thematic boreal forest classification of forest environments.
