Journal ArticleDOI
Light upconversion by triplet–triplet annihilation in diphenylanthracene-based copolymers
TL;DR: In this article, a new strategy based on covalent tethering of diphenylanthracene (DPA) emitters to a polymeric backbone is reported, which aims to optimize the efficiency of this photophysical process in glassy polymeric materials by increasing the emitter content.
Journal ArticleDOI
Elucidating the Potential Biological Impact of Cellulose Nanocrystals
Sandra Camarero-Espinosa,Carola Endes,Silvana Mueller,Alke Petri-Fink,Barbara Rothen-Rutishauser,Christoph Weder,Martin J. D. Clift,E. Johan Foster +7 more
TL;DR: In this article, the authors highlight how knowledge obtained from studying the biological impact of other nanomaterials can provide a basis for future research strategies to deduce the possible human health risks posed by cellulose nanocrystals.
Journal ArticleDOI
Liquid crystalline, highly luminescent poly(2,5-dialkoxy-p-phenyleneethynylene)
TL;DR: A high molecular weight poly(2,5-dialkoxy-p-phenyleneethynylene) derivative has been prepared by the Heck reaction of 1,4-bis(2-ethylhexyloxy)-2-5-diiodobenzene and 1, 4-diethynyl-2, 5-dioctyloxybenzene.
Journal ArticleDOI
Influence of mechanical treatments on the properties of cellulose nanofibers isolated from microcrystalline cellulose
Davide Bandera,Janak Sapkota,Sébastien Josset,Christoph Weder,Philippe Tingaut,Xin Gao,E. Johan Foster,E. Johan Foster,Tanja Zimmermann +8 more
TL;DR: The possibility of preparing cellulose whiskers-like materials by mechanical treatment of commercially available microcrystalline cellulose (MCC) was explored in this article, where high shear homogenization, grinding with a supermass colloider, and hammer-milling were the processes selected to disintegrate the MCC.
Journal ArticleDOI
Mechanical and shape‐memory properties of poly(mannitol sebacate)/cellulose nanocrystal nanocomposites
Agueda Sonseca,Sandra Camarero-Espinosa,Laura Peponi,Christoph Weder,E. Johan Foster,Jose Maria Kenny,Enrique Giménez +6 more
TL;DR: In this article, Sonseca, A, Camarero-Espinosa, S, Peponi, L, Weder, C, Foster, E J, Kenny, J M, & Gimenez, E (2014) Mechanical and shapememory properties of poly (mannitol sebacate)/cellulose nanocrystal nanocomposites.
