“…8,9 Moreover, bamboo is hygroscopic and rich in sugar and starch, which causes BPCs to be easily attacked by mold fungi. 10 These shortcomings limit the application of BPCs in structural materials. Improving the mechanical properties and mold resistance of BPCs is still needed.…”

“…However, the low compatibility of bamboo fiber and the polymer matrix leads to poor interface quality in BPCs, which is detrimental to their mechanical properties 8,9 .

“…However, there are relatively few studies on improving the mechanical properties of BPCs using white‐rot fungi. In addition, the parenchyma cells of bamboo are rich in starch, sugar, protein and so on; these nutrients are the main factors that cause mildew of bamboo 10 . Studies have shown that the growth of white‐rot fungi was related to consumption of reducing sugar in lignocellulosic biomass, 22 which mean that pretreatment with white‐rot fungi would lead to a decrease in nutrients of bamboo with the mold resistance of BPCs improved.…”

Mechanical toughness and mold resistance of bamboo-plastic composites (BPCs) are essential for the application on structural materials. However, limited work has used biological methods to improve these properties of BPCs. In this study, the white-rot fungus Trametes versicolor was selected to modify bamboo fibers by short-term incubation. Modified bamboo fibers were then used to reinforce high-density polyethylene to prepare BPCs. Compared to the unmodified BPCs, the BPCs pre-treated with T. versicolor showed increases in elongations at break and impact strength, and these increases became more obvious with the incubation time increased. The improved mechanical toughness was assumed to the selective removal of lignin reduced rigidity of raw materials, and the increase of specific surface areas and pore volumes enhanced mechanical interlocking of the composites. Surfaces of BPC pretreated for 15 days were free of mold spores, yielding mold inhibition efficiency of up to 100%. It suggests that metabolism of reducing sugars would efficiently improve the mold resistance of BPCs. A novel, eco-friendly bioprocess for modifying the interface between bamboo and plastic was successfully established, and it allows BPCs to be widely applied in the field of outdoor living structures.

“…Under these circumstances, the bamboo internode attracts our interest because of its unique porous structure. Mainly consisting of lignin and cellulose, 30 the bamboo internode can be facilely converted into conductive carbon material with porous monolithic structure by carbonization. Therefore, rather than following the complex cathode preparation method based on the "ink-based" process, it is more effective to directly carbonize the bamboo internode to produce a self-supported framework for electrode, and then to regulate the pore structure to facilitate mass transport, and to introduce doping heteroatoms for high-density distribution of ORR active sites in the subsequent process.…”

Commercial applications of direct liquid fuel cells require a high-performance, cost-effective, robust, and mechanically/chemically stable cathode for the oxygen reduction reaction. In this study, a membrane-less direct formate fuel cell (DFFC) was constructed by using a Fe–N-doped bamboo internode as the binder-free and monolithic air-breathing cathode and a Pd-electrodeposited graphite rod as the anode. The effect of the preparation procedures including alkali activation, pyrolysis with (NH4)3PO4, and solvothermal treatment with iron phthalocyanine on the physicochemical properties of the cathode is studied with respect to the textural structure, electrical conductivity, and heteroatom incorporation. The results indicated that the resulting cathode exhibited proper distribution of primary/secondary pores for the transport of reactants and ions. Additionally, these procedures effectively increased the electrical conductivity and heteroatom incorporation in the carbon matrix of the as-obtained cathode. The fabricated membrane-less DFFC delivered an open-circuit voltage of 1.04 V and a maximum power density of 10.01 ± 0.16 mW cm–3 with a limiting current density of 48.95 ± 1.84 mA cm–3. In addition, this DFFC achieved a high columbic efficiency of 92.3% after 7 h of discharge with one-fueling. Furthermore, the 110 h discharge test at 10 mA cm–3 demonstrated that the DFFC fabricated with the Fe–N-doped bamboo internode cathode exhibited good stability, showing its promising application as an inexpensive power supply in portable electronics.

“…Bamboo is a general term for more than 1250 species of woody grasses in 75 genera belonging to the family Poaceae and subfamily Bambusoideae, which is widely distributed all over the world. − Because of its large output of biomass, much faster growth rate than trees, and very similar chemical composition (50–70% holocellulose and 20–25% lignin) to wood, ,, bamboo is considered as a good substitute of timber in the wood industry. Recently, as an outstanding renewable plant resource, bamboo is receiving more and more attention to be used as a biomass resource for bioenergy and biofuel applications.…”

Dynamic Variation of Fuel Properties of Tonkin Cane (Pseudosasa amabilis) during Maturation

et al. 2015

Bamboo is a potential feedstock for bioenergy production. Pseudosasa amabilis is a common bamboo species in south China and commonly known as Tonkin Cane. It has a high biomass yield, and its properties are outstanding compared to many other bamboo species as well as grasses and woody biomass for bioenergy applications. Bamboo can mature within 1 year, and its chemical composition changed slightly after the growth during the first year. To understand the effect of the maturation process on fuel properties, biomass materials of P. amabilis ranging from 0.5 m bamboo shoot to 1-year-old bamboo culm were investigated for chemical composition, crystallinity index (CrI), element contents (i.e., C, H, N, S, and O), heating values, and thermogravimetric characteristics. Except for the H content, which did not show an apparent changing trend, and the lignin content, which had a relatively stable increasing rate, the other tested properties changed significantly during the maturation process of the bamboo and rapidly before the age stage of high growth accomplishment of the bamboo. The CrI showed the same changing pattern with the cellulose content. In comparison to some grass and woody biomass materials, C and H contents of 1-year-old mature bamboo were higher, whereas N, S, and O contents were lower, which are advantageous for bioenergy utilization. The higher heating value of 1-year-old bamboo was more than 19 MJ/kg, even higher than some of the woody biomass feedstocks. The results from this study ensure that 1 year growth is enough for the Tonkin Cane to obtain a good quality biomass for biofuel production.
