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 ...

Effect of autohydrolysis on Pinus radiata wood for hemicellulose extraction

10.1016/j.carbpol.2018.04.010

2018-04-07

The extraction of hemicellulose from pine wood was studied by applying autohydrolysis treatment. A central composite experimental design was carried out using different temperatures (150-190 °C) and times (30–90 min) to select the most favorable operating con...

Cyclic nigerosyl-1,6-nigerose-based nanosponges: An innovative pH and time-controlled nanocarrier for improving cancer treatment

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
