“…Recently, a novel method to pulverize hierarchically organized bio-based materials into nano-objects using only the collision energy of dual water jets was invented by Kondo et al [71][72][73][74][75][76][77][78][79]. This technique termed "aqueous counter collision" (ACC) successfully dissociates the weaker intermolecular interactions such as van der Waals forces in bio-based materials without any chemical modification.…”

Nanocelluloses are natural materials with at least one dimension in the nano-scale. They combine important cellulose properties with the features of nanomaterials and open new horizons for materials science and its applications. The field of nanocellulose materials is subdivided into three domains: biotechnologically produced bacterial nanocellulose hydrogels, mechanically delaminated cellulose nanofibers, and hydrolytically extracted cellulose nanocrystals. This review article describes today's state regarding the production, structural details, physicochemical properties, and innovative applications of these nanocelluloses. Promising technical applications including gels/foams, thickeners/stabilizers as well as reinforcing agents have been proposed and research from last five years indicates new potential for groundbreaking innovations in the areas of cosmetic products, wound dressings, drug carriers, medical implants, tissue engineering, food and composites. The current state of worldwide commercialization and the challenge of reducing nanocellulose production costs are also discussed.

“…Recently, it has been shown that the characteristics of the nanocellulose surface depend on the preparation process. Most nanocellulose generally possesses hydrophilic surfaces [27], but the ACC process can create more hydrophobic planes on nanocellulose surfaces [25,28,29].…”

This study attempts to clarify thermodynamic quantification on interaction between poly(vinyl alcohol) (PVA) and wood-derived cellulose nanofibrils (CNFs) obtained by aqueous counter collision (ACC) method. Aqueous mixtures of PVA/ACC-CNFs with various fiber widths were cast as the target materials. The interfacial interactions between the two components were characterized through thermodynamic evaluation of the crystalline PVA component as a probe in the cast mixture. As the result, surface properties of the ACC-CNFs found to reflect on the crystallization behavior of the interacted PVA component, resulting in dual nano-size effects of either diluent or nucleating agent. Melting point depression behaviors of the PVA component indicated that ACC-CNFs with thinner widths induced nucleation effects on PVA crystallization, whereas ACC-CNFs with ca. 100 nm in width encouraged diluent effects on PVA components. It is noted that this trend found to be reverse to the case for PVA/ACC-CNFs of bacterial nanocellulose previously reported.

“…Notably, both EFB and hardwood pulp fibre precipitation volumes increased from 0 to 10 collisions. The volume tends to increase with progressing miniaturisation of the pulp fibre (Saito et al 2006, Tsuboi et al 2014. Therefore, the miniaturisation of both pulp fibre types progresses until at least 10 collisions.…”

Empty Fruit Bunches (EFB) are byproducts in the palm oil industry. Recently, many studies focused on the application of EFB to pulp fibre and paper. In this study, we used a nanoengineered mechanical treatment, aqueous counter collision (ACC), to investigate the miniaturisation behavior of chemical EFB pulp fibre and compared it with chemical hardwood pulp fibre. Furthermore, a sheet was prepared from fine EFB fibre produced by ACC to examine the wettability. The miniaturisation of the EFB pulp fibre using ACC progressed more quickly than that of hardwood pulp fibre, and finally, nanofibre was obtained from the EFB. The width of nanofibre was the same as hardwood chemical pulp fibre. A drop of water didn't penetrate into the sheet but spread on the sheet surface within 10 s. The water contact angle of the fine EFB fibre sheet depended strongly on the number of collision in ACC treatment than that of the fine hardwood fibre sheet.
