A simple and inexpensive method for producing water-stable pulp fibre yarns using a deep eutectic mixture composed of choline chloride and urea (ChCl/urea) was developed in this work. Deep eutectic solvents (DESs) are eutectic mixtures consisting of

Dissolved cellulose was contacted with dissolved linear or slightly branched lignophenol polymers in alkaline solution, and films were formed through precipitation. Lignophenol is a polymeric lignin derivative isolated from wood meal, and due to its

Polymer composites with nanocellulose as the reinforcing agent often lack good compatibility between the two components. In this study, we have combined cellulose nanofibrils (CNFs) and cellulose nanocrystals (CNCs) in different ratios to create all-

During the era of industrialization, over the period 1850–2019, the total anthropogenic emissions, caused by human activities, have been around 2390 billion tons of carbon dioxide. These concentrations are now higher than any time during the past 2

2,5-Furandicarboxylic acid (FDCA) has received attention as an emerging bio-based building block with many applications, especially in renewable polyesters. The common route to FDCA uses the unstable 5-hydroxymethylfurfural (HMF) as an intermediate.
Reusable face masks are one major protective measure in droplet infection, even the efficiency has been discussed in aerosol distribution and wide use in population. In epidemic and especially in pandemic condition security of supply is compromised d
