Journal ArticleDOI
Advanced Biomass-Derived Electrocatalysts for the Oxygen Reduction Reaction
TL;DR: Recent progress in advanced nanostructures synthesized from biomass resources for the oxygen reduction reaction (ORR) is reviewed and the resulting electrocatalytic activity and durability are introduced and compared to those from conventional Pt/C-based Electrocatalysts.
Journal ArticleDOI
Pickering emulsions stabilized by cellulose nanocrystals grafted with thermo-responsive polymer brushes.
TL;DR: Cellulose nanocrystals from ramie fibers are studied as stabilizers of oil-in-water emulsions and the effect of temperature can be counterbalanced with the addition of salt which is explained by the reduction of electrostatic and steric interactions of poly(NIPAM)-g-CNCs at the oil-water interface.
Journal ArticleDOI
The effect of chemical composition on microfibrillar cellulose films from wood pulps: water interactions and physical properties for packaging applications
Kelley L. Spence,Richard A. Venditti,Orlando J. Rojas,Orlando J. Rojas,Youssef Habibi,Joel J. Pawlak +5 more
TL;DR: In this paper, microfibrillated celluloses (MFCs) and associated films generated from wood pulps of different yields (containing extractives, lignin, and hemicelluloses) have been investigated.
Journal ArticleDOI
Porous N,P-doped carbon from coconut shells with high electrocatalytic activity for oxygen reduction: Alternative to Pt-C for alkaline fuel cells
Maryam Borghei,Nikorn Laocharoen,Elo Kibena-Põldsepp,Leena-Sisko Johansson,Joseph Campbell,Esko I. Kauppinen,Kaido Tammeveski,Orlando J. Rojas +7 more
TL;DR: In this article, a new, environmentally-friendly method to synthesize N,P-doped porous carbon by high conversion of coconut shell residues for the reduction of oxygen in alkaline media was introduced.
Journal ArticleDOI
The effect of chemical composition on microfibrillar cellulose films from wood pulps: Mechanical processing and physical properties
Kelley L. Spence,Richard A. Venditti,Youssef Habibi,Orlando J. Rojas,Orlando J. Rojas,Joel J. Pawlak +5 more
TL;DR: Interestingly, after homogenization, the presence of lignin significantly increased film toughness, tensile index, and elastic modulus, indicating that MFC films can potentially be made from low-cost recycled cellulosic materials.
