“…Numerous journal studies can be found to examine the properties and the effective applications of the bamboo fibers. The properties of bamboos are reported recently by Xu et al [6], Tanpichai et al [7] and Hai et al [8], while the application is of the bamboo on the structure [9][10][11] and related fabrication of bamboo fibers are publicly revealed by Zhang et al [12]. The temperature effects on bamboo fibers were examined and found that the bamboo fiber reinforced epoxy composite (BFREC) with 40% fiber volume fraction exhibited the highest tensile and flexural strength compared to polyester and vinyl ester composites [6].…”

The aim of this work is to characterize particle of bamboo leaves charcoal produced by ball milling process. The characterization parameter are the particle size and the morphology of the particle. The milling process was completed in a cylinder vial made from stainless steel. The milling element was a steel ball. The dimension of the cylinder vial was 120 mm length and 1 inch diameter, while the ball diameter was 0.25 inch. The charcoal was crushed manually then sieved with a filter size of 200 meshes. The particles passing the filter were then put together with the milling balls into cylinder vial. The cylinder vial was shaken to have ball collision for the size reduction. The shaker machine was operated at 1000 rpm for 2 million cycles. The empty space in the vial was varied for 1/2, 1/3, 1/4 and 1/5 empty space of vial volume. Further work is done to see the effect of the machine speed to the characteristics of particles. The machine is operated at 800 rpm, 900 rpm, 1100 rpm for 1/5 empty space and 0.25 inch ball diameter. Particle size analyzer (PSA) was used to measure average particle size, while Scanning electron microscope (SEM) and Energy Dispersive X-ray (EDX) were employed to see the particle morphology and the content of elements in the bamboo leaf charcoal. The results showed that the average size of particles is in the range of 300 nm to 600 nm. There is no certain relationship between final particle size and percentage of vial volume empty space. The SEM results showed that the particle shape is irregular as a result of fracture due to collision. The most dominant element is carbon which is more than 60% and the second is silicon dioxide (silica) which is more the 20%.

“…The addition of cellulose nanostructures having a high surface to volume ratio improves the formation of hydrogen bonding within cellulose pulp which increases density boosting the mechanical performance of paper. Tanpichai et al [34] reported significant enhancement of mechanical properties of the paper composed of 50 wt% nanofibrillated cellulose (NFC). Tensile strength and strain were 10-fold and 3-fold higher than those of the paper without NFC, respectively.…”

Here, we designed the composition of the coating of the paper sheets composed of chitosan, bacterial cellulose (nanofibres), and ZnO with boosted antibacterial and mechanical activity. We investigated the compositions with ZnO exhibiting two different sizes/shapes: (1) rods and (2) irregular sphere-like particles. The proposed processing of bacterial cellulose resulted in the formation of nanofibers. Antimicrobial behavior was tested using E. coli ATCC® 25922™ following ASTM E2149-13a standard. Mechanical properties of the paper sheets were measured by comparison of tearing resistance, tensile strength, and bursting strength according to ISO 5270 standard. The increased antibacterial response is assigned to the combination of chitosan and ZnO (independently of its shape and size), while the boosted mechanical behavior is due to bacterial cellulose nanofibers. Therefore, the proposed composition is an interesting multifunctional mixture for coatings in food packaging applications.

“…Plant cellulose (PC) is difficult to degrade when compared to bacterial cellulose (BC). The fact is that PC presents a ribbon structure in a complicated manner when compared to BC and moreover, PC is composed of impurities, such as pectin, hemicellulose, and lignin [ 42 , 43 ]. Meanwhile, a compact fibrous microstructure and a high degree of crystallinity contribute to the slow degradation of BC and this exhibits a less amorphous phase.…”

Cellulose is a naturally existing element in the plant’s cell wall and in several bacteria. The unique characteristics of bacterial cellulose (BC), such as non-toxicity, biodegradability, hydrophilicity, and biocompatibility, together with the modifiable form of nanocellulose, or the integration with nanoparticles, such as nanosilver (AgNP), all for antibacterial effects, contributes to the extensive usage of BC in wound healing applications. Due to this, BC has gained much demand and attention for therapeutical usage over time, especially in the pharmaceutical industry when compared to plant cellulose (PC). This paper reviews the progress of related research based on in vitro, in vivo, and clinical trials, including the overall information concerning BC and PC production and its mechanisms in wound healing. The physicochemical differences between BC and PC have been clearly summarized in a comparison table. Meanwhile, the latest Food and Drug Administration (FDA) approved BC products in the biomedical field are thoroughly discussed with their applications. The paper concludes on the need for further investigations of BC in the future, in an attempt to make BC an essential wound dressing that has the ability to be marketable in the global marketplace.
