“…After the chemical reduction of GO to rGO, the ordered crystal structure of rGO was restored as a peak was observed at 18.7 • [33]. The weak and broad diffraction peak of rGO exhibits the interlayer spacing between graphene and restoration of graphitic structure after the chemical reduction [34]. CNF/PEG has a peak at 23.2 • owing to the presence of PEG, while CNF/rGO has a peak of around 25.1 • , which indicates the reduction of oxygen-containing functional groups in GO structures [35].…”

The recognition of nanocellulose has been prominent in recent years as prospect materials, yet the ineffectiveness of nanocellulose to disperse in an organic solvent has restricted its utilization, especially as a reinforcement in polymer nanocomposite. In this study, cellulose has been isolated and defibrillated as cellulose nanofibrils (CNF) from oil palm empty fruit bunch (EFB) fibers. Subsequently, to enhance its compatibility with UV-curable polyurethane (PU)-based resin, the surface hydrophilicity of CNF has been tailored with polyethylene glycol (PEG), as well as reduced graphene oxide (rGO). The dispersibility of reinforced modified CNF in UV-curable PU was examined through the transmittance interruption of resin, chemical, and mechanical properties of the composite printed using the stereolithographic technique. Evidently, the enhanced compatibility of modified CNF and UV-curable PU was shown to improve the tensile strength and hardness of the composites by 37% and 129%, respectively.

“…Moreover, due to the electroactive properties of levodopa and tryptophan, those can be determined by electrochemical methods. Electrochemical technique is a good alternative to the aforementioned methods due to the faster response, higher selectivity, higher sensitivity, reproducibility, easy operation and lower cost [10][11][12][13][14].…”

This work discusses the development of a new sensor for simultaneous determination of levodopa and tryptophan. The proposed sensor was a glassy carbon electrode modified with V2O5 nanoparticles. Based on the excellent electrochemical properties of the modified electrode, a sensitive voltammetric method was used for individual and simultaneous determination of the levodopa and tryptophan in the aqueous solutions. The proposed method under the optimized conditions was utilized to determine the levodopa with linear range of 0.06-250.0 μM and detection limit of 0.02 μM (S/N=3). Finally, the applicability of the proposed sensor was verified by evaluation of levodopa and tryptophan in real sample.

As (III) regularly requires oxidation to As (V), before it can be removed from water. Here, we reported photocatalytic removal of As (III) as well as adsorption of As (III) and As (V) using a novel, porous magnetic Ag/TiO2/Fe3O4@GO nanocomposite which was characterized via FT-IR, XRD, SEM, and TEM. A mathematical model (the central composite design) was used to estimate the relationship between the observed adsorption and our set of variables including initial concentration of arsenic ions, adsorbent dosage, pH, and the contact time. An optimum adsorption capacity of about 91% was observed for As (III) using 20 mg adsorbent with 24 ppm initial concentration of As (III), at pH = 5, within 90 min, and room temperature. Likewise, an optimum adsorption capacity of about 87% was observed for As (V) using 11 mg adsorbent with 17 ppm initial concentration of As (V), at pH = 3, within 30 min, and room temperature. The electrostatic factors between surface charge of nanocomposite and arsenic species were used to explain adsorption behavior of As (III) and As (V) at different conditions. The Langmuir isotherm equations best interpreted the nature of adsorption of As (III) and A (V). It was found during phocatalytic process maximum R% was about 63% for As (III) using 40 mg photocatalyst. Arsenic Adsorption Photocatalyst Magnetic nanocomposite Ag nanoparticles M.
