WebTable 2.1) which, in turn, can reduce the randomness of the patterns.56 Conversely, BF yielded a lower distribution of grayscale levels with closely distributed textural features (Figures 2.3a, 2.4a, Table 2.1). A less generalized response can be found for materials imaged by polarized light as the response is highly dependent on the material (Table … WebIn addition, Liu et al. [15] prepared a high-performance wood adhesive by cross-linking dialdehyde cellulose with branched amine-based polymers, compensating for the lack of water resistance of dialdehyde cellulose. However, we intend to further develop green, environmentally-friendly, and water-resistant all-bio-based adhesives, considering the …
