Journal ArticleDOI
Development and characterization of thin polymer films relevant to fiber processing
TL;DR: In this paper, dilute solutions of cellulose, polypropylene, polyethylene, nylon and polyester were spun cast onto gold and silica wafers to generate thin films of these polymers, which are commonly used in the manufacture of synthetic fibers.
Journal ArticleDOI
Bioactive Cellulose Nanofibrils for Specific Human IgG Binding
TL;DR: The effects of initiator concentration and thickness of poly(AMA-co-HEMA) layer on hIgG adsorption were investigated in the developed systems, which exhibited high signal-to-noise response.
Journal ArticleDOI
Magneto-responsive hybrid materials based on cellulose nanocrystals
Tiina Nypelö,Carlos Rodríguez-Abreu,José Rivas,Michael D. Dickey,Orlando J. Rojas,Orlando J. Rojas +5 more
TL;DR: In this article, self-standing films of cellulose nanocrystals (CNC) and electrospun composite fibers with CNC and polyvinyl alcohol both with magnetic properties arising from cobalt iron oxide nanoparticles in the CNC matrix were fabricated.
Journal ArticleDOI
Asymmetric cellulose nanocrystals: thiolation of reducing end groups via NHS–EDC coupling
TL;DR: In this article, a mild asymmetric thiolation procedure was proposed as an efficient alternative to conventional reductive amination, and the adsorption of thiolated CNC onto gold surfaces as well as the viscoelastic property of the formed adlayer was investigated by using quartz crystal microgravimetry.
Journal ArticleDOI
High Axial Ratio Nanochitins for Ultrastrong and Shape-Recoverable Hydrogels and Cryogels via Ice Templating
Liang Liu,Long Bai,Anurodh Tripathi,Juan Yu,Zhiguo Wang,Maryam Borghei,Yimin Fan,Orlando J. Rojas +7 more
TL;DR: High yield (>85%) and low-energy deconstruction of never-dried residual marine biomass is proposed following partial deacetylation and microfluidization, which results in chitin nanofibrils of ultrahigh axial size (nanochitin, NCh), one of the largest for bioderived nanomaterials.
