“…Thus, from a practical perspective, the association is described as irreversible, a phenomenon usually referred to as hornification in the pulp and paper community. This has large consequences for the industrial use of nanocellulose since fibrils have to be kept in their dispersed state, with large transportation costs as a consequence (Posada et al 2020). The extent of hornification depends strongly on drying methods (Peng et al 2012; Nodenstro ¨m 2020) and can also be mitigated by additives such as glycerol (Moser et al 2018), which presumably act as spacers between fibrils.…”

In the cellulose scientific community, hydrogen bonding is often used as the explanation for a large variety of phenomena and properties related to cellulose and cellulose based materials. Yet, hydrogen bonding is just one of several molecular interactions and furthermore is both relatively weak and sensitive to the environment. In this review we present a comprehensive examination of the scientific literature in the area, with focus on theory and molecular simulation, and conclude that the relative importance of hydrogen bonding has been, and still is, frequently exaggerated.

“…In another study, the addition of 2% CNC in polyalphaolefin oil (PAO/ CNC) provided a substantial increase in viscosity compared to pure PAO. According to the authors, increasing the viscosity of a fluid containing cellulose nanoparticles facilitates the formation of a lubricating film and the separation of solid contacts in the boundary lubrication regime 31 …”

“…The use of cellulose nanoparticles has been proposed for being an “ecologically correct” additive, in addition to presenting good dispersion in aqueous‐based fluids. In addition to properties such as biodegradability, low density, high mechanical strength, high surface area, and morphology have been widely explored and identified as potentially valuable for replacing toxic elements used as lubricant additives 14,31,32 . Recent studies show promising results from aqueous and non‐aqueous based nanolubricants using cellulose nanocrystals, but the literature is still scarce 33,34 .…”

This work aimed to prepare and characterize cellulose nanocrystals as an additive to a water‐based lubricating fluid. Different concentrations of the cellulose nanocrystals suspensions (0.50–1.25%wt) were added to the lubricant fluid. The nanolubricants were submitted to the pin‐disk test. The rigid/severe electrodynamic lubrication regime was conducted under different rotation speeds (500 and 63 rpm) and external loads (8.47 and 1.77 N). The cellulose nanocrystals showed a high yield (74%), an aspect ratio from 23 to 35, and thermal stability at 219.0°C. The coefficient of friction increased from 4% to 97%) with the addition of the cellulose nanocrystals for the test at 500 rpm and decreased by up to 50% at 63 rpm both at 8.47 N. The wear rate reduced with increasing concentration of nanocrystals in the lubricant fluid, showing a reduction by up to 99% at 500 rpm–8.47 N compared with fluid without nanocrystals.

“…The appropriate cellulose nanofibers can be assembled into a variety of structures, such as capsules, particles, Pickering stabilized lipophilic droplets, films, wet-stable foams, aerogels, and solid materials containing closed cells. These structures can result in tailored sustained release kinetics, and rapid release of poorly soluble drugs ( Löbmann and Svagan 2017 ; Posada, Velásquez-Cock et al, 2020 ; Pandey 2021 ). One recent study described cellular solid materials containing closed cells that could be self-assembled using cellulose nanofibers to encapsulate poorly-soluble drugs.…”

Antibiotic resistant microorganisms have become an enormous global challenge, and are predicted to cause hundreds of millions of deaths. Therefore, the search for novel/alternative antimicrobial agents is a grand global challenge. Cellulose is an abundant biopolymer with the advantages of low cost, biodegradability, and biocompatibility. With the recent growth of nanotechnology and nanomedicine, numerous researchers have investigated nanofibril cellulose to try to develop an anti-bacterial biomaterial. However, nanofibril cellulose has no inherent antibacterial activity, and therefore cannot be used on its own. To empower cellulose with anti-bacterial properties, new efficient nanomaterials have been designed based on cellulose-based nanofibrils as potential wound dressings, food packaging, and for other antibacterial applications. In this review we summarize reports concerning the therapeutic potential of cellulose-based nanofibrils against various bacterial infections
