Study of the Application of Alkaline Extrusion to the Pretreatment of Eucalyptus Biomass as First Step in a Bioethanol Production Process

open access: yesEnergies, 2018
Eucalyptus biomass was studied as a feedstock for sugars release using an alkaline extrusion plus a neutralization-based pretreatment. This approach would be a first step in a bioconversion process aimed at obtaining fuel bioethanol from eucalyptus ...

Laser‐Welded Cellulose‐Carbon Nanotube Nanocomposites as a 3D Scaffold of Si Anodes for High‐Performance Lithium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A Si anode comprising entangled networks of cellulose and SWCNT (C‐CNT) nanocomposites as an anode electrode for a high‐performance LIB is realized by fully utilizing the generated microstructure of a novel conductive 3D scaffold via a low‐temperature and eco‐friendly process. Additionally, localized heating via photo‐thermal conversion can be utilized
