Special Issue Information

Dear Colleagues,

Cellulose-based nanomaterials, such as nanofibrillated celluloses, nanocrystalline celluloses, and bacterial celluloses, have demonstrated significant contributions to sustainability due to their high potential as biodegradable and renewable alternatives to non-biodegradable materials. These materials can serve as flocculants, dispersants, emulsifiers, and polymers used across various industrial sectors, including papermaking, construction, electronics, food processing, and even medicine.

Cellulose-based nanomaterials have attracted the attention of many researchers because of their unique physical and optical properties, as well as their ability to be modified to present the desired electric, electrostatic, chemical, and magnetic properties. Cellulose-based nanomaterials have been proven to have a high potential in reinforcing composite materials, modifying the rheology of suspensions, dispersing and aggregating particles, storing and releasing water and active substances, stabilizing emulsions, acting as barriers for gases and oils, serving as a skeleton for tissue growth, protecting wounds and burns, adsorbing pollutants, providing thermal insulation, and more. This new generation of nanomaterials based on cellulose is called to replace materials with high environmental impact. However, achieving this future requires further research to address knowledge gaps that currently hinder the production and commercialization of these materials.

This Special Issue welcomes novel contributions to the knowledge on cellulose-based nanomaterials, including nanopapers, nanoflocculants, nanocomposites, and other materials based on or modified with nanocelluloses, such as cement, plastics, paper, and more. Full papers, short communications, and reviews are welcome.

Abstract
This study evaluated the stability and reusability of amino-functionalized nanocellulose aerogels as CO2-adsorbent materials. The modified aerogels, synthesized via a controlled silylation using N-[3-(trimethoxysilyl) propyl] ethylenediamine (DAMO), demonstrated excellent thermal stability up to 250 °C (TGA) and efficient CO2 adsorption [...] Read more.
This study evaluated the stability and reusability of amino-functionalized nanocellulose aerogels as CO2-adsorbent materials. The modified aerogels, synthesized via a controlled silylation using N-[3-(trimethoxysilyl) propyl] ethylenediamine (DAMO), demonstrated excellent thermal stability up to 250 °C (TGA) and efficient CO2 adsorption through chemisorption, which was the main adsorption mechanism. The performance of the aerogels was assessed using both adsorption isotherms and the decay pressure technique, revealing that CO2 adsorption capacity increased with higher amino group loading (4.62, 9.24, and 13.87 mmol of DAMO). At 298 K and 4 bar, CO2 adsorption capacity increased proportionally with the amino group concentration, reaching values of 3.17, 5.98, and 7.86 mmol of CO2 g−1 polymer, respectively. Furthermore, over 20 adsorption/desorption cycles, the aerogels maintained 95% CO2 desorption at ambient temperature, indicating their potential for industrial use. These findings highlight the aerogels suitability as stable, reusable materials for large scale CO2 capture and storage technologies. Full article

One challenge for 3D printing is that the mortar must flow easily through the printer nozzle, and after printing, it must develop compressive strength fast and high enough to support the layers on it. This requires an exact and difficult control of the superplasticizer (SP) dosing. Nanocrystalline cellulose (CNC) has gained significant interest as a rheological modifier of mortar by interacting with the various cement components. This research studied the potential of nanocrystalline cellulose (CNC) as a mortar aid for 3D printing and its interactions with SPs. Interactions of a CNC and SP with cement suspensions were investigated by means of monitoring the effect on cement dispersion (by monitoring the particle chord length distributions in real time) and their impact on mortar mechanical properties. Although cement dispersion was increased by both CNC and SP, only CNC prevented cement agglomeration when shearing was reduced. Furthermore, combining SP and CNC led to faster development of compressive strength and increased compressive strength up to 30% compared to mortar that had undergone a one-day curing process.
