Forthcoming articles have been peer-reviewed and accepted for publication but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

Forthcoming articles must be purchased for the purposes of research, teaching and private study only. These articles can be cited using the expression "in press". For example: Smith, J. (in press). Article Title. Journal Title.

  • Characterisations of carbon/copper oxide nanowire (CCONW) composite based on pre-carbonised date palm leaves (PCDPLs), carbon black (CB), and copper (Cu)   Order a copy of this article

    Abstract: Carbon/copper oxide nanocomposites face challenges in mechanical strength and electrical conductivity, limiting their applications due to their inherent limitations. This study aims at improving such limitations by preparing a carbon/copper oxide nanowire composite utilising self-adhesive pre carbonised date palm leaves (PCDPLs) and carbon black (CB) for mechanical and electrical performance enhancement. PCDPLs are favoured due to their eco-friendliness, adhesion properties, and enhanced electrical conductivity when combined with copper. In this study, synthesised composite was characterised by X-ray diffraction (XRD), energy-dispersive X-ray diffraction (EDXD), scanning electron microscopy (SEM), and four-point probe measurements at 1000 C. The findings demonstrated that values of Youngs modulus enhanced from 13.9 GPa to 26.98 GPa and increased electrical conductivity from 5.77 1cm1 to 35.85 1cm1 with increased (CB + Cu) content from 0% to 50%, respectively. Such a composite is promising for applications in those industries that require outstanding conductivity along with structural integrity.

  • A comprehensive review on 3D-printed bio-ceramic scaffolds: current trends and future direction   Order a copy of this article
    by Tanyu Donarld Kongnyui, Debashish Gogoi, Manjesh Kumar 
    Abstract: Many ceramic materials have become significant in the biomedical field due to their bio-compatibility, because of which it is called bio ceramics. These materials generally have the properties of biocompatible, bioresorbable, bioactive, or bioinert, with the choice of bio-ceramic depending on their application. Characterisation techniques such as optical microscopy, surface analysis, mechanical property assessment, and chemical composition evaluation are mostly used to study these scaffolds in different literature. Bio ceramics, with their biocompatibility and osteoconductive properties, have advanced bone repair and tissue engineering. However, traditional manufacturing methods often lack the precision for complex implants. 3D bioprinting addresses this by allowing the precise addition of bio-ceramic inks to create customised scaffolds. This paper examines the improvement in the mechanical properties and biocompatibility of printed bio-ceramic scaffolds, their current uses in tissue engineering, recent developments, and prospects. This will help in choosing bio-ceramics based on intended applications with different 3D printing processes available at present.
    Keywords: bio-ceramics; bioprinting; tissue engineering (TEg); bone repair; 3D printing; mechanical properties; biocompatibility.

  • Zeolite-biopolymer nanocomposites in bone tissue engineering   Order a copy of this article
    by Rana Kafili Zangbar, Reza Manafzadeh, Ali Nivpour, Mehrdad Farahmandnejad, Saeid Sabzehali Sabzehali, Faezeh Ziyadini Dashtkhaki 
    Abstract: The field of tissue engineering is a combination of several fields to expand and use new materials for the treatment of tissue defects. Among materials with porous structures, zeolite with a wide range of pores as an effective biocompatible material can be used in the construction of bone tissue engineering scaffolds. The specific surface area of Nano zeolites is much higher than the specific surface area of micro zeolites and this additional surface area leads to more reactivity or functionalization. By combining zeolite with biopolymers, nanocomposites can be synthesized that are more similar to natural bone tissue than zeolite. The bioactive zeolite gives the nanocomposite scaffold strength and bone conductivity, while the polymeric matrix provides structural support for cell adhesion and subsequent cellular processes leading to tissue development. Therefore, in this study, the effect of using zeolite biopolymer nanocomposites as bone tissue engineering scaffolds has been investigated.
    Keywords: nanocomposites; zeolites; biopolymer; tissue engineering; nanozeolite; porous structures; polymeric matrix; scaffolds; bioactive; bone defects.
