Journal ArticleDOI
Space-resolved thermal properties of thermoplastics reinforced with carbon nanotubes
TL;DR: In this paper, a space-resolved thermal analysis (TA) integrated with atomic force microscopy (AFM) was used to detect thermal expansion and thermal transitions of composite materials.
Journal ArticleDOI
In-Plane Compression and Biopolymer Permeation Enable Super-stretchable Fiber Webs for Thermoforming toward 3-D Structures
Alexey Khakalo,Jarmo Kouko,Ilari Filpponen,Elias Retulainen,Orlando J. Rojas,Orlando J. Rojas +5 more
TL;DR: In this article, a facile and green method that combines mechanical and biopolymer treatment was proposed for cellulosic fibers, which enabled network extensibility and increased tensile strength and stiffness.
Journal ArticleDOI
Effect of water activity on the functional, colloidal, physical, and microstructural properties of infant formula powder
Robertus Wahyu N. Nugroho,Marko Outinen,Outi Toikkanen,Antti Heino,Daisuke Sawada,Orlando J. Rojas,Orlando J. Rojas +6 more
TL;DR: Interestingly, no major changes in the pH and colloidal characteristics, including particle size and distribution, stability, and sedimentation were observed in the reconstituted IF powder upon storage for 6 weeks, indicating a negligible contribution from possible Maillard reactions.
Journal ArticleDOI
Surface functionalization and size modulate the formation of reactive oxygen species and genotoxic effects of cellulose nanofibrils
Kukka Aimonen,Monireh Imani,Mira Hartikainen,Satu Suhonen,Esa Vanhala,Carlos Moreno,Orlando J. Rojas,Hannu Norppa,Julia Catalán +8 more
TL;DR: In this article , surface composition and size of cellulose nanofibrils were evaluated to determine the potential toxic response to CNFs in human bronchial epithelial BEAS-2B cells.
Journal ArticleDOI
Experimental and Predictive Description of the Morphology of Wet-Spun Fibers
TL;DR: In this paper, an alternative predictive approach based on the combination of relative energy difference (RED) of Hansen solubility and a kinetic parameter (T) that considers mass transfer effects was proposed for the determination of the diameter and internal morphology of wet-spun fibers.
