“…Cellulose and nanocellulose show similar characteristics in various spectra; in other words, spectroscopy is the most convenient way to identify them. The X-ray diffraction (XRD) patterns and Fourier-transform infrared (FTIR) spectra of CNCs are shown in Figure 3d [48]. The characteristic peaks at 14.9 • , 16.5 • , 22.8 • , and 34.1 • in the XRD patterns correspond to the (1-10), (110), (200), and (004) crystal planes of the natural cellulose, respectively, and both the bulky cellulose and the nanofibers of cellulose obtained with different methods exhibited these features.…”

Cellulose-based conductive materials (CCMs) have emerged as a promising class of materials with various applications in energy and sensing. This review provides a comprehensive overview of the synthesis methods and properties of CCMs and their applications in batteries, supercapacitors, chemical sensors, biosensors, and mechanical sensors. Derived from renewable resources, cellulose serves as a scaffold for integrating conductive additives such as carbon nanotubes (CNTs), graphene, metal particles, metal–organic frameworks (MOFs), carbides and nitrides of transition metals (MXene), and conductive polymers. This combination results in materials with excellent electrical conductivity while retaining the eco-friendliness and biocompatibility of cellulose. In the field of energy storage, CCMs show great potential for batteries and supercapacitors due to their high surface area, excellent mechanical strength, tunable chemistry, and high porosity. Their flexibility makes them ideal for wearable and flexible electronics, contributing to advances in portable energy storage and electronic integration into various substrates. In addition, CCMs play a key role in sensing applications. Their biocompatibility allows for the development of implantable biosensors and biodegradable environmental sensors to meet the growing demand for health and environmental monitoring. Looking to the future, this review emphasizes the need for scalable synthetic methods, improved mechanical and thermal properties, and exploration of novel cellulose sources and modifications. Continued innovation in CCMs promises to revolutionize sustainable energy storage and sensing technologies, providing environmentally friendly solutions to pressing global challenges.

“…Durian husk was collected from a local market in Binh Thuan province (Vietnam). The extraction procedure of nanocellulose from durian husk was inherited from our previous report with some minor modifications (Thach-Nguyen et al, 2022). After washing with distilled water, durian husk was ground and dried at 100 °C overnight.…”

<p>In the present study, nanocellulose was successfully extracted from durian husk via chemical treatment and then characterized by several analytical techniques, involving X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), energy-dispersive X-ray spectroscopy (EDX) and transmission electron microscopy (TEM). Nanocellulose was obtained with a crystallinity index of 77% and in the form of cellulose nanofibrils (30 nm in width and micrometers in length). Using nanocellulose as a biosorbent in solid-phase extraction technique, the inorganic arsenic ions were eluted using 0.1 M HNO3 and its content in the eluate solution was quantified by hydride generation-flame atomic absorption spectrometry (HG-FAAS), in which the recovery of arsenic ions using nanocellulose were assessed via contact time, pH and dosage of sorbent, reaching the equilibrium after 30 minutes. With the limit of detection (LOD) of 0.41 ng mL-1, the limit of quantification (LOQ) of 1.38 ng mL-1 and the relative standard deviation of repeatability (%RSD) of 3.44% (with ten replicates) for arsenic determination, the present method was practiced with the trace inorganic arsenic quantification in real samples (fish sauce with various protein levels) with reliable spike recoveries.</p>

Bacterial cellulose (BC) is a natural substance produced by microorganisms and offers numerous bene ts. It can be produced by utilizing biomass waste which is abundantly available through the fermentation process. This study investigates the utilization of pineapple peel waste for bacterial cellulose synthesis and observes their properties as nanocomposites membrane after the addition of ZnO nanoparticles (ZnO-NPs). The experimental methods were conducted by synthesizing BC using pineapple peel extract using fermentation process. Subsequently, BNC was synthesized using a high-pressure homogenizer, and ZnO-NPs nanoparticles were added as reinforcement at concentrations of 2.5 wt.%, 5.0 wt.%, and 7.5wt.%. The mixture was sonicated and subsequently dried in an oven at 60°C for 20 h. BNC/ZnO-NPs membranes were characterized using XRD, FTIR, tensile test, BET, antibacterial test, and SEM analysis. The results indicate that the membrane structure of BNC/ZnO-NPs nanocomposite has peaks at diffraction angles of 14.4°, 15.2°, 16.9°, 22.8°, 31.6°, 34.1°, and 36.8°. The addition of ZnO-NPs affects the crystallite size and pore diameter of the membrane. It enhances the crystalline index of BNC by 81.37% at 2.5wt.% ZnO-NPs but reduces the membrane strength. The surface morphology of nanocomposite shows agglomeration with increasing ZnO-NPs content. Membrane BNC/ZnO-NPs show antibacterial activity against S.aureus.
