Summary

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.

    Synthesis of Carbon dots from Biomass Chenpi for the Detection of Hg2+

    Jun Xiang, Xiaoqing Chen, Qi Liu, Huihua Jing, Tongqiang Chen, Wanli Tang, Wenyang Xu
    Journal of Renewable Materials, Vol.11, No.10, pp. 3739-3750, 2023, DOI:10.32604/jrm.2023.028090

    Abstract Biomass-derived carbon dots (C-dots) are considered a very important carbon material in metal ion detection of their small environmental impact, simple preparation process, and relatively low cost. A green approach for synthesizing biomass-derived C-dots from Chenpi using a hydrothermal method without further processing is proposed in the present study. The as-synthesized C-dots show excellent fluorescence properties, superior resistance to UV irradiation photobleaching, and high photostability in salt-containing solutions. The C-dots were used in the form of label-free fluorescent probes for sensitively detecting Hg2+ selectively. The outcome relationship behaved linearly and was established based on a given More >

    A Review of Graphene Oxide Crosslinking as Enhanced Corrosion Shield Application

    Nurul Anis Athirah Ab Aziz, Chin Wei Lai, Boon Hoong Ong
    Journal of Renewable Materials, Vol.11, No.6, pp. 2745-2770, 2023, DOI:10.32604/jrm.2023.025899

    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… More >

    Low-Temperature Synthesis of Nano-AlN Based on Solid Nitrogen Source by Plasma-Assisted Ball Milling

    Zhuoli Yang, Xianbin Hou, Leyang Dai
    Journal of Renewable Materials, Vol.11, No.6, pp. 2941-2951, 2023, DOI:10.32604/jrm.2023.025723
    (This article belongs to the Special Issue: Carbon-Based Nanomaterials from Renewable Materials: Synthesis, Properties and Applications)
    Abstract Plasma-assisted ball milling was carried out on the Al+C3H6N6 system and Al+C4H4N4 system, respectively. The phase structure, functional groups and synthesis mechanism were analyzed by XRD and FT-IR, and the differences in the synthesis process of nano-AlN with different solid nitrogen sources were discussed. The results show that C3H6N6 has a stable triazine ring structure, and its chemical bond is firm and difficult to break, so AlN cannot be synthesized directly by solid-solid reaction at room temperature. However, there are a large number of nitrile groups (-CN) and amino groups (-NH2) in C4H4N4 molecules. Under the combined… 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… 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

    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… More >
