With the emerging technology in the 21st century, carbon based nanomaterials are used in numerous fields. The new nano-based entities are being strongly generated and incorporated into everyday personal care products, cosmetics, medicines, drug delivery, and clothing to impact industrial and manufacturing sectors, which means that nanomaterials commercialization and nano-assisted device will continuously grow. The focus of the special issue is the detailed literature data and discussion regarding the carbon based nanomaterials from renewable materials such as bamboo, by-products of crops, fruits, plants and cottons. Those renewable raw materials are (nearly) inexhaustible natural resources, the supply of which can be restored in a short period of time as well as contain many valuable components. Additionally, design and development of carbon based nanomaterials into different structure such as carbon nanotubes, biomass, cellulose, graphene oxide and graphene assemblies has gained significant scientific interest and becomes the most studied material as it exhibits promising functional properties. Innovative new approaches and synthesis of a high quality carbon-based nanomaterials from different renewable materials are critical and crucial for determining the potential of the material in various promising applications such as environmental pollution management, renewable energy system as well as energy storage system. This special issue describes the novel concept of different forms of carbon based nanomaterials which are of value to researchers in developing cost effective and user friendly products, devices, or systems. In order to fully exploit the potential of carbon-based nanomaterials, developing low cost, environment-friendly nanocomposite from renewable material resources is certainly a research direction that should be extensively investigated in the future.

    Abstract Nowadays, corrosion is not only undesirable, but it also has a significant influence on the industrial sectors and technical innovations that have demand for metals. The global economic damage is expected to reach $2.5 trillion, equivalent to more than 3.4% of the world’s GDP in 2013. It is linked with significant financial harm, manufacturing pollution, and safety issues. An electrochemical process primarily induces metal corrosion at the metalelectrolyte interface region, caused by steel oxidation and the reduction of oxygen, protons, and water. Therefore, organic and epoxy coatings can be applied as protective coatings. Additionally, it can prevent metal corrosion in… More >

    Abstract Gallium nitride (GaN)/porous silicon (PSi) film was prepared using a pulsed laser deposition method and 1064 nm Nd: YAG laser for optoelectronic applications and a series of Psi substrates were fabricated using a photoelectrochemical etching method assisted by laser at different etching times for 2.5–15 min at 2.5 min intervals. X-ray diffraction, room-temperature photoluminescence, atomic force microscopy and field emission scanning electron microscopy images, and electrical characteristics in the prepared GaN on the Psi film were investigated. The optimum Psi substrate was obtained under the following conditions: 10 min, 10 mA/cm2, and 24% hydrofluoric acid. The substrate exhibited two highly cubic crystalline structures at (200)… More >

    Graphene-Based Active Tunable Metasurfaces for Dynamic Terahertz Absorption and Polarization Conversion

    Haoran Wei, Tian Ji, Jianqing Huang
    Journal of Renewable Materials, Vol.11, No.2, pp. 731-743, 2023, DOI:10.32604/jrm.2022.022283
    (This article belongs to this Special Issue: Carbon-Based Nanomaterials from Renewable Materials: Synthesis, Properties and Applications)
    Abstract Simultaneous broadband absorption and polarization conversion are crucial in many practical applications, especially in terahertz communications. Thus, actively tunable metamaterial systems can exploit the graphene-based nanomaterials derived from renewable resources because of the flexible surface conductivity and selective permeability of the nanomaterials at terahertz frequencies. In this paper, we propose a graphene-based active tunable bifunctional metasurface for dynamic terahertz absorption and polarization conversion. The graphene ring presents a certain opening angle (A) along the diagonal of the xoy plane. When A = 0°, the proposed metasurface behaves as a broadband absorber. Numerical results show the feasibility of achieving this polarization-insensitive… More >
