Summary

With the current development of nanotechnology field, many different high-quality with cost-effective nanomaterials have come into use in various applications. However, the needs for renewable resources-based nanomaterials are inevitable and increasing gradually in the last few years. Therefore, the scientists attempt to use the renewable resources as the feedstocks for the development of their desired products. The current special issue “Current advances in green nanomaterials applications” presents to readers the articles covering different aspects of the synthesis, characterizations and applications of the renewable resources-based nanomaterials.

  • Green Method, Optical and Structural Characterization of ZnO Nanoparticles Synthesized Using Leaves Extract of M. oleifera
  • Abstract ZnO nanoparticles (ZnO-NP) present innovative optical, electrical, and magnetic properties that depend on specific characteristics, e.g., size, distribution, and morphology. Thus, these properties are essential to address various applications in areas such as electronics, medicine, energy, and others. In addition, the performance of this ZnONP depends of their preparation which can be done by chemical, physical, and biological methods. Meanwhile, nowadays, the main interest in developing ZnO-NP synthesis through biological methods bases on the decrease of use of toxic chemicals or energy applied to the procedures, making the process more cost-effective and environmentally friendly. However, the large-scale production of nanoparticles… More

  • Corrosion Protection of 5083 AA in Saline Water by Polyacrylonitrile Nanofibers
  • Abstract Polymeric nanofibers are a promising technology to protect the metal surfaces from corrosion. Through the literature search, the use of polyacrylonitrile nanofibres (PANNFs) as a corrosion inhibitor coating for aluminum alloys has not been evaluated. This work includes the development of a new, lightweight, high surface area and efficient coating of PANNFs that produced using electrospinning process to resist the corrosion of aluminum alloys (AA5083) which immersed in 0.6 M NaCl at alkaline medium (pH = 12) and acidic medium (pH = 1) at a range of temperatures (293–323) K. The PANNFs coating was successfully deposited on AA 5083 specimens,… More

  • Preparation and Electrorheological Response of PAL/TiO2/PANI Nanorods
  • Abstract Using palygorskite (PAL) as template, the PAL/TiO2/PANI nano-rods were synthesized by heterogeneous precipitation and in-situ polymerization. The synthesized PAL/TiO2/PANI nanorods were used as a novel electrorheological (ER) fluid by mixing with silicone oil, which showed excellent ER effect. The yield stress of the PAL/TiO2/PANI based ER fluid (15 vol%) reached 8.8 kPa under 4 kV mm−1 electric field. The dynamic shear stress of the PAL/TiO2/PANI based ER fluid could maintain a stable level in the shear rate range of 0.1–100 s−1 . Furthermore, the PAL/TiO2/PANI ER fluid exhibited excellent suspension stability. More

  • Synthesis and Characterization of Green Potassium Nanoparticles from Sideroxylon Capiri and Evaluation of Their Potential Antimicrobial
  • Abstract In the present study, the green synthesis of potassium nanoparticles (K-NPs) was assessed using aqueous extract of Sideroxylon capiri. The potassium nanoparticles were analyzed by UV-visible spectroscopic techniques, X-ray spectrometers of energy dispersive (SEM-EDS) and dynamic light scattering. The results showed high values at 3.5 keV confirming the formation of potassium nanoparticles and the SEM analysis showed an agglomerated particles size between 360 to 200 nm with a spherical morphology. The K-NPs showed an effective antibacterial activity against the test organisms mainly with Bacillus cereus, Enterobacter aerogenes, Fusarium solani and Botrytis cinerea. However further studies about nanotoxicity of K-NPs are… More

  • Physical Properties of SiC Nanostructure for Optoelectronics Applications
  • Abstract A SiC nanofilms have been deposited and investigated on quartz and silicon substrates using pulsed laser deposition technique with the 300 pulses of Nd: YAG laser at two different laser wavelengths of 1064 nm and 532 nm. The structural, morphological, and optical properties of the deposited nanostructure SiC were prepared and characterized as a function of the wavelengths of the used laser. The structural result shows four different pecks at (111), (200), (220), and (311) planes related to Nano SiC. The transmission result presents that the optical energy gap value for the SiC nanostructure is depended on the wavelength of… More

  • Recycling of Mud Derived from Backwash Wastewater Coagulation as Magnetic Sodalite Sphere for ZnAdsorption
  • Abstract

    Herein, we reported a method to prepare magnetic sodalite sphere by using the mud from backwash wastewater after polyaluminum chloride (PAC) coagulation. The results showed that approximately 100% of Fe in the wastewater was precipitated as flocculent iron mud (FM) by adding PAC. FM was converted to spherical magnetic sodalite (FMP) with a diameter of 3 μm via a facile alkali hydrothermal method without adding Al/Si resources or reductant. The product FMP had the saturated magnetization of 10.9 emu g−1 and high Zn2+ adsorption capacity of 50.6 mg g−1. Without coagulation with PAC, the removal rate of Fe from the… More

  • Healing Effect and Underlying Mechanism of Silver Nanoparticles Prepared Using Carboxymethyl Chitosan under Solar Irradiation
  • Abstract In our previous study, silver nanoparticles were prepared using AgNO3 and carboxymethyl chitosan (CMCS) which is commercially available with solar irradiation. In this study, the efficacy and safety of silver nanoparticles prepared by this method were evaluated for healing wounds in rats with diabetes. We also attempted to determine the underlying mechanism and influencing factors of the silver nanomaterial preparation method. Compared with growth factors, silver nanoparticles exhibit better healing effects for rats with diabetes. No remnant silver ions were detected in the major organs of these rats after the application of silver nanoparticles. Silver nanoparticles prepared using CMCS are… More

  • Properties of ABS/Organic-Attapulgite Nanocomposites Parts Fabricated by Fused Deposition Modeling
  • Abstract The paper discusses the mechanical and thermal performance manifested in natural nanorods attapulgite (ATP) reinforced Acrylonitrile butadiene styrene (ABS) nanocomposites in the process of fused deposition modeling (FDM). Molten extrusion technique was taken to manufacture the filaments of ABS/organic-attapulgite (OAT) nanocomposites with different mass fraction and the printing operation was made by one commercial FDM three-dimensional (3D) printer. Results indicate that the mechanical performance of these FDM 3D printed specimens are improved obviously via the introduction of OAT, and tensile strength of the ABS/OAT nanocomposites parts with only 2 wt% OAT addition is enhanced by 48.1%. At the same time,… More
