Biodiesel Production from Hevea brasiliensis Seeds: A Systematic Review

open access: yesVietnam Journal of Chemistry, EarlyView.
ABSTRACT The Hevea brasiliensis (HB) species, also called the rubber tree, is currently cultivated worldwide for the extraction of latex, an input for rubber production. In addition, its seeds currently have few productive applications, despite their high oil content.

A Splitting Architecture for Exact Reduced Coulomb Friction

open access: yesComputer Graphics Forum, EarlyView.
Abstract Existing approaches to frictional contact dynamics typically either modify the Coulomb law to improve numerical robustness or solve the exact law in a fully coupled monolithic form. However, in its reduced form, exact Coulomb friction can be written as a cone complementarity problem with an augmented velocity, which reveals a natural split ...

Fault‐Controlled Permeability: A Key Parameter in Geothermal Electricity Production Assessment

open access: yesTerra Nova, EarlyView.
ABSTRACT Geothermal energy is central to the global green energy transition, but its development has long focused on regions with positive thermal anomalies. Through a semi‐quantitative global‐scale review and spatial analysis of 361 geothermal sites, we show that 56.2% of global geothermal electricity production occurs in regions with thermal ...
