Cellulose is the most ubiquitous polymer found in nature. In recent years, cellulose derivatives of various kinds, such as cellulose esters and ethers, and nanocelluloses, have become popular bioprintable materials used for making bio-inks because of their affordability, biocompatibility, biodegradability, and printability. Nevertheless, the potential uses of nanocellulose and cellulose derivative-based bio-inks have not been thoroughly explored. This review emphasizes advancements in the design of cellulose-based bio-inks for 3D bioprinting of diverse tissues as well as the physicochemical attributes of cellulose derivatives and nanocellulose that make them a viable choice for bio-inks in 3D bioprinting. Additionally, cellulose bio-inks' current benefits and drawbacks in 3D printing are thoroughly examined. Various cross-linking approaches are offered for multicomponent cellulose and nanocellulose-based bio-inks to control the fidelity of the ink and alter the mechanical stiffness in the printed hydrogel construct as a bioactive cue. By emphasizing the interactions involving cells and the matrix, it additionally examines the effect of functional groups and surface charge on nanocellulose on vital cellular functions (including cell survival, adhesion, and proliferation). Thus, this review aims to offer an integrated platform for 3D bioprinting with cellulose-based materials for the biomedical industry.

Cellulose-derived materials, like paper and cellulose acetate, are known to be vulnerable to degradation within museum collections. Studies have been conducted and degradation markers have been identified on these materials. However, the degradation of man-made cellulose-derived fibres in collections is not well understood.

The present study aims to develop and characterize cannabidiol (CBD) solid dispersions using Vacuum Compression Molding (VCM) to enhance the drug solubility and release profile. Solid dispersions of CBD and polymers were processed using VCM at 130 °C for 4 min after a prior physical mixing. Five percent w/w of CBD was used with 5% w/w of poloxamer 188 and 90% w/w of polymeric carrier (Polyethylene Oxide, PEO-N80 or Hydroxypropyl cellulose, HPCEF).

The simultaneous hydrolysis of cellulose and hemicellulose involves trade-offs, making precise control of hydrolysis products crucial for sustainable development. This study employed three machine learning (ML) models-Random Forest (RF), Extreme Gradient Boosting (XGB), and Support Vector Machines (SVM)-to simulate and predict the yields of xylose (Xyl), furfural (FF), glucose (Glu), 5-hydroxymethylfurfural (5-HMF), and levulinic acid (LA) in a phosphoric acid/acetone/water system. The RF model demonstrated the highest accuracy, with R values between 0.

This study investigates lignocellulose nanofibrils (LCNF) as a sustainable alternative material for printed circuit board (PCB) substrates, demonstrating an application through the development of an eco-friendly computer mouse demonstrator. LCNF is derived from lignin-rich cellulose pulp, a side stream product of biorefinery processes, combining the natural strength of cellulose fibrils with lignin to enhance mechanical and electrochemical properties. The research outlines the process of fibrillating lignin-rich cellulose pulp at 10 kW/h per kg into LCNF, followed by thermal and pressure treatment (at Δp = 50 - 1500 kN, ΔT = 30 - 120 °C) to achieve a rigid PCB substrate.
