Bamboo, with its high strength-to-weight ratio as a fiber-reinforced composite material, has wide applications throughout the world. Tre Gai (bambusa stenostachya) bamboo is a popular industry material in Vietnam. This paper attempts to characterize the microstructure and mechanical properties of Tre Gai bamboo through a variety of tests and models. Volume fraction of fiber sheath with radial p...

INTRODUCTION We report an unusual case of corneal lamellar injury caused by long bamboo splinters. CASE PRESENTATION A 70-year-old Japanese man visited our hospital with a bamboo injury. Slit lamp examination revealed that a bundle of bamboo splinters had deeply penetrated the corneal stroma of the right eye from the nasal limbus. The splinters were approximately 8 mm in length, but had not p...

This study, using the method of direct collection feces, investigated captive giant pandas daily intakes and apparent digestibility coefficients of diet dominantly comprised of Phyllostachys vivax bamboo shoots. The results showed that the captive giant pandas daily ingested ~2818 g (dry mass) of bamboo shoots (corresponding to ~42 kg of fresh bamboo shoots with shells). Based on this daily int...

Bamboo occupies an important phylogenetic node in the grass family and plays a significant role in the forest industry. We produced 1.2 Mb of tetraploid moso bamboo (Phyllostachys pubescens E. Mazel ex H. de Leh.) sequences from 13 bacterial artificial chromosome (BAC) clones, and these are the largest genomic sequences available so far from the subfamily Bambusoideae. The content of repetitive...

This study examined the antibacterial activity of moso bamboo shoot skin (Phyllostachys pubescens). Bamboo shoot skin itself and its dichloromethane extract had antibacterial activity against Staphylococcus aureus. Results suggest the possibility of effective utilization for antibacterial materials of bamboo shoot skins which are mainly scrapped today. Introduction Recently, chemical food addit...

A combination of steam explosion (SE) and alkaline peroxide (AP) used to pretreat bamboo was investigated. Steam explosion at 224 °C for 4 min was applied to bamboo, and the pretreated bamboo was delignified by alkaline peroxide. Enzymatic hydrolysis was compared in the pretreated samples. Steam pretreatment led to remarkable hemicellulose solubilization (63.2%). Lignin solubilization (93.1%) w...

Question: What changes occur as a consequence of the massive flowering and senescence of the dominant understory species of bamboo, Chusquea culeou (E. Desvaux)? In this study, we documented some of the ecological consequences of this rare event that occurred in 2001, the previous flowering having occurred more than 60 years ago. Location: Nothofagus temperate forest, Patagonia, Argentina. Meth...

This study aims at exploring ways of making the use of bamboo reinforced concrete beams simple, efficient and cost-effective for rural construction with Ghana as a case study. It is a comparative study of bamboo reinforced concrete beams with shear links made of different materials. The web materials considered were bamboo, rattan cane and steel. Sixteen (16) beams were tested to failure under ...

Ball-milled bamboo was pre-swelled with a cold aqueous solution of NaOH and urea, and then reacted directly with benzyl chloride to synthesize benzylated bamboo. The effects of the molar ratio of benzyl chloride to OH groups in the bamboo (1 to 4), the reaction temperature (70 to 110 °C), and the reaction time (2 to 8 h) on both the product yield and the degree of substitution (DS) were evaluat...

High surface area activated carbon fibers (ACF) have been prepared from bamboo by steam activation after liquefaction and curing. The influences of activation temperature on the microstructure, surface area and porosity were investigated. The results showed that ACF from bamboo at 850 °C have the maximum iodine and methylene blue adsorption values. Aside from the graphitic carbon, phenolic and ...
