The development of new strategies for wound healing has resulted in the design of biomedical devices using polymers of natural origin. Hydrogels are biomaterials formed by three-dimensional polymeric networks that can retain large amounts of water or biological fluids, and smooth texture similar to living tissue. Chitosan is a linear polysaccharide, (1-4)-2-amino-2deoxy-ß-D-glucan, which has desirable features such as biocompatibility, non-toxicity, hemostasis and antibacterial character. Xyloglucans have different applications in tissue engineering for their physicochemical properties, biocompatibility and control of cell expansion. Hydrogels had been made of homogeneous mixtures prepared of chitosan and purified xyloglucan, followed by a freeze-drying process to develop a flexible and porous structure. Additionally, their mechanical properties such as porosity, solubility, biodegradation, and the antibacterial activity of the hydrogels are studied. The results suggest that the incorporation of xyloglucan favors the characteristics from chitosan-based hydrogels, providing a promising alternative for application in biomaterials with antimicrobial activity.

“…As the second most abundant natural polymer, lignin accounts for about 30% of the organic carbon in the biosphere, and it is composed of aromatic monomers [9]. In the process of plant growth, lignin is polymerized in vivo via an enzyme-mediated dehydrogenation polymerization (lignification), resulting in a cross-linked amorphous material with both C-C and ether bonds [10]. Moreover, lignin plays an important role in strengthening cell-to-cell connections, increasing cell wall strength and resisting pathogens during subsequent growth [11].…”

Bamboo is a gramineous plant widely distributed in China and has great prospects. Normally, local people cut bamboo culm at first year for paper milling or at six years for construction. Understanding lignin changes in bamboo with aging is necessary for better exploring the application of bamboo at different ages and can also promote the application of bamboo more effectively. Based on the previous study, the chemical structure and the lignin content of bamboo at different ages were further explored by FT-IR, GPC, NMR and other chemical methods in this paper. Results showed that the lignin structures of bamboo at different ages were similar with three monomers of S, G and H, but the molecular weight increased with age. Quantitative structure estimation further confirmed that S-type lignin content and S/G ratio of bamboo lignin constantly increased with age.

“…[20] The peak at 1735 cm À 1 representatives the C=O stretching vibration, which is the characteristic peak of hemicellulose. [21] This peak was formed due to the pyrolysis of hemicellulose. The stretching vibration of the lignin aromatic ring and C=O stretching vibration occurred at 1599 cm À 1 .…”

Biomass‐based carbon materials have attracted much attention in the field of microwave absorption because of their light weight, environmental friendliness, low cost and high efficiency. In this work, carbon matrix of porous microtubule structure with different magnetic particles was synthesized from natural luffa sponge by a simple calcination process. The carbon matrix possesses hierarchical porous structures including micrometer‐scale tubular channels, nanometer‐scale macrospores, mesopores and micropores, of which microspores are the most. The Fe3O4, FeO/α‐Fe, α‐Fe/γ‐Fe and α‐Fe/Fe3C particles were formed in the temperature range of 700–1000 °C. The porous carbon/α‐Fe@Fe3C composites obtained at 1000 °C exhibit excellent microwave absorption (MA) performance, its minimum reflection loss can reach −48.9 dB with only a thickness of 1.5 mm, and the effective absorption bandwidth (RL≤−10 dB) is 3.86 GHz. The porous structure, synergies between dielectric loss and magnetic loss, high attenuation constant are the key factors for good MA performance.
