Cello-oligomers have a wide application range and are gained from three different cello-oligomer production paths, which show different drawbacks, namely acid or alkaline hydrolysis of cellulose, chemical or enzymatic synthesis, and enzymatic hydroly

Long chain cellulose esters (LCCE) are bio-based materials, which are biodegradable, can be prepared from renewable materials, and have relatively good mechanical and barrier properties. In this study, we tested the feasibility of various LCCEs as a

Herein we combine in a novel way the physical effect of porous structure of a cellulosic aerogel with the chemical effect of long alkyl tails by a well known homogeneous green esterification method, to achieve purely bio-based and highly water repell

Increased reactivity of cellulose in ionic liquids was revealed when cellulose was protected with a 4-methoxytrityl moiety in the imidazolium-based ionic liquid, 1-allyl-3-methylimidazolium chloride ([amim]Cl). Selectively protected 2,6-di- O -(4-met

A new interaction between assembled tritylated cellulose (6TC) chains was seen when cellulose was selectively substituted at C-6 position. This obtained interaction was concluded to arise from the π–π stacking between the trityl moieties on cellu

A novel cellulose derivative was designed and synthesised to investigate its liquid crystalline as well as self-assembly properties leading to supramolecular structures. The cellulose derivative was characterised with NMR, TGA, DSC, XRD and polarizin

Tosylation and acylation of cellulose were performed under mild reaction conditions using imidazolium based ionic liquids (ILs) as solvents. The non-degradative nature, lower viscosity, as well as higher solubility of cellulose in [amim]Cl encouraged

In contrast to the success in artificial DNA- and peptide-based nanostructures, the ability of polysaccharides to self-assemble into one-, two-, and three-dimensional nanostructures are limited. Here, we describe a strategy for designing and fabricat

Chloroform-soluble palmitic and decanoic acid esters of cellulose were synthesized from the reaction of MCC with acid chlorides in LiCl/DMA and the ionic liquid [amim]Cl, as novel cellulose solvents. A process of derivatization of the remaining hydro
