Journal ArticleDOI
Retention of lysozyme activity by physical immobilization in nanocellulose aerogels and antibacterial effects
Khan Mohammad Ahsan Uddin,Hannes Orelma,Hannes Orelma,Pezhman Mohammadi,Maryam Borghei,Janne Laine,Markus Linder,Orlando J. Rojas +7 more
TL;DR: Results indicate that non-toxic and biodegradable CNF is a suitable support for bio-active materials and is effective in protecting and retaining enzymatic and antibacterial activities.
Journal ArticleDOI
Selective Laser Sintering of Lignin-Based Composites
Rubina Ajdary,Niklas Kretzschmar,Hossein Baniasadi,Jon Trifol,Jukka Seppälä,Jouni Partanen,Orlando J. Rojas,Orlando J. Rojas +7 more
TL;DR: In this paper, the effect of lignin as a suitable component for selective laser sintering of polyamide (PA12) was examined to evaluate the effect on 3D-printing of high axial aspect objects.
Journal ArticleDOI
Expanding the upper limits of robustness of cellulose nanocrystal aerogels: outstanding mechanical performance and associated pore compression response of chiral-nematic architectures
Anurodh Tripathi,Anurodh Tripathi,Blaise L. Tardy,Saad A. Khan,Falk Liebner,Orlando J. Rojas,Orlando J. Rojas +6 more
TL;DR: In this paper, the liquid crystalline phase transitions in aqueous dispersions of highly anisometric, nanoscaled and high strength (EA > 150 GPa) cellulose nanocrystals (CNCs) were exploited to enable chiral-nematic ordered aerogels with controlled meso-and microstructures.
Journal Article
Cellulose nanocrystals-based nanocomposites: fruits of a novel biomass research and teaching platform
Xiaodong Cao,Youssef Habibi,Washington Luiz Esteves Magalhães,Orlando J. Rojas,Lucian A. Lucia +4 more
TL;DR: This research presents a novel and scalable approach to Forest Biomaterials that combines photolysis, 3D image analysis, and 3D simulation that allows for real-time analysis of the physical properties of timber-based composite materials.
Journal ArticleDOI
Fenton's reagent-mediated degradation of residual Kraft black liquor.
Elisa Araujo,Antonio J. Rodríguez-Malaver,Aura M. González,Orlando J. Rojas,Nancy Peñaloza,Johnny Bullón,Mayra A. Lara,Natalia Dmitrieva +7 more
TL;DR: It is shown that Fenton’s reagent and H2O2 alone can degrade residual Kraft black liquor under acidic conditions at room temperature.
