“…These fibrils have diameters of approximately 10–20 nm,194 and the angle between the fibril direction and the direction of the tracheid, the microfibril angle, is 3°–5° for normal wood, but can be as high as 50° for compression wood 195–198. The fibrils themselves consist of elementary cellulose fibrils with diameters of 2–4 nm and hemicelluloses, specifically glucomannan, between the elementary fibrils and xylan at the surface linking the fibrils to the surrounding lignin,199–202 Figure 7c. These fulfill different mechanical functions as part of the hierarchical nanocomposite wood 196, 203–206…”

Bioinspired materials research is a continuously growing fi eld in interdisciplinary materials science and engineering with large potential for novel functional materials. One possibility of combining the hierarchical structure of natural materials with the broad range of available constituent materials is biotemplating, i.e., the use of biological materials as scaffolds or casting molds for the synthesis of ceramics, semiconductors, metals, polymers or composites thereof. However, the replication of structural details of complex biological tissues over several levels of hierarchy down to the nanometer level is still a big challenge. The biological templates need to be (made) accessible for the precursor materials down to the nanometer scale, and the desired inorganic replica often require a fi nal thermal treatment with the danger of collapse of the nanostructure. Here, some of the current knowledge about the replication of hierarchical biological materials into ceramics or carbons with special emphasis on wood as a template is reviewed. It is concluded that real hierarchical replication down to the nanometer scale requires a careful preparation of the biological template, followed by elaborate template infi ltration via gas or liquid phases and their transformation into a solid, and fi nally, the gentle removal of the template. Not surprisingly, retaining the replicated material in an amorphous or nanocrystalline state is a key requirement for a successful nanometer-scale replication of biological materials.

Membrane-based materials with special surface wettability have been applied widely for the treatment of increasing industrial oily waste water, as well as frequent oil spill accidents. However, traditional technologies are energy-intensive and limited, either by fouling or by the inability of a single membrane to separate all types of oil-water mixtures. Herein, a biomimetic monolayer copper membrane (BMCM), composed of multiscale hierarchical dendritic structures, is cleverly designed and successfully fabricated on steel mesh substrate. It not only possesses the ability of energy-efficient oil-water separation but also excellent self-recovery anti-oil-fouling properties (<150 s). The BMCM even keeps high separation efficiency (>93%) after ten-time cycling tests. More importantly, it retains efficient oil-water separation capacity for five different oils. In fact, these advanced features are benefited by the synergistic effect of chemical compositions and physical structures, which is inspired by the typical nonwetting strategy of butterfly wing scales. The findings in this work may inspire a facile but effective strategy for repeatable and antipollution oil-water separation, which is more suitable for various applications under practical conditions, such as wastewater treatment, fuel purification, separation of commercially relevant oily water, and so forth.
