Extraction and characterization of molecular properties of rye grain starch and its susceptibility to the resistant starch formation 10.1016/j.carbpol.2018.04.024 2018-04-10 The aim of this work was to isolate starch from different parts of rye grain by a traditional and newly developed enzymatic method, and to compare the physical, chemical and molecular properties of isolated starches, especially focusing on susceptibility to r...
On the potential of using nanocellulose for consolidation of painting canvases 10.1016/j.carbpol.2018.04.020 2018-04-09 Nanocellulose has been recently proposed as a novel consolidant for historical papers. Its use for painting canvas consolidation, however, remains unexplored. Here, we show for the first time how different nanocelluloses, namely mechanically isolated cellulos...
Cellulosic Cr(salen) complex as an efficient and recyclable catalyst for copolymerization of SO2 with epoxide 10.1016/j.carbpol.2018.04.031 2018-04-07 The search for green catalytic processes for the synthesis of useful polymers and incorporating the waste SO2 in highly-selective pathways become extremely important in the coming years. Herein, cellulose was modified by ethylenediamine, and then synthesized ...

A cross-linked polymer was obtained by reacting a tetraglucose, named cyclic nigerosyl-1-6-nigerose ...
High-humidity hot air impingement blanching alters texture, cell-wall polysaccharides, water status and distribution of seedless grape 10.1016/j.carbpol.2018.04.023 2018-04-06 Blanching pretreatment plays an essential role in fruits and vegetables processing to obtain excellent final products. The purpose of current work was to characterise the texture, cell-wall polysaccharides and water distribution of grapes pre- and post- high-...
Preparation of spherical porous hydrogel beads based on ion-crosslinked gum tragacanth and graphene oxide: Study of drug delivery behavior 10.1016/j.carbpol.2018.04.022 2018-04-05 In this study, new spherical pH-sensitive porous hydrogel beads were prepared based on the water-soluble gum tragacanth (GT) polysaccharide and graphene oxide (GO) nanosheets by using Ca+2 and Ba+2 ions as crosslink agents, calcium carbonate particles as soli...
Cellulose nanofibers from banana peels as a Pickering emulsifier: high-energy emulsification processes 10.1016/j.carbpol.2018.04.001 2018-04-04 Cellulose nanofibers (CNFs) from banana peels was evaluated as promising stabilizer for oil-in-water emulsions. CNFs were treated using ultrasound and high-pressure homogenizer. Changes on the size, crystallinity index and zeta potential of CNFs were associat...
Design of reusable novel membranes based on bacterial cellulose and chitosan for the filtration of copper in wastewaters 10.1016/j.carbpol.2018.04.007 2018-04-04 This study has been carried out to design novel, environmentally friendly membranes by in situ and ex situ routes based on bacterial cellulose (BC) as a template for the chitosan (Ch) as functional entity for the elimination of copper in wastewaters. Two rout...
Sodium alginate-grafted submicrometer particles display enhanced reversible aggregation/disaggregation properties 10.1016/j.carbpol.2018.04.012 2018-04-04 In this article, we demonstrate that submicrometer particles with surface-grafted sodium alginate (SA) display enhanced and reversible aggregation/disaggregation properties in aqueous solution. 300 nm silica particles were first functionalized with an aminosi...
