Additive Manufacturing Techniques for Fabrication of Bone Scaffolds for Tissue Engineering Applications

Received: 26 June 2020;  Published: 08 September 2020;  doi: 10.21926/rpm.2003021

Abstract

Bone tissue engineering (BTE) as a modern and more effective treatment for bone defects has recently received lots of attention. One of the pivotal parts of BTE is the “scaffold”, which functions as an indwelling carrier of cells and additives, as well as, providing a foundation for cell growth and eventually forming new, native-like bone. Up to now, many methods and materials have been employed to manufacture bone scaffolds. This review focuses on providing both basic knowledge of BTE as well a [...]

Wave Propagation and Scattering due to Debonding in CFRP Strengthened Reinforced Concrete Beams

Received: 28 May 2020;  Published: 27 August 2020;  doi: 10.21926/rpm.2003020

Abstract

Carbon fibre reinforced polymer (CFRP) systems as sheets or plates are commonly used to strengthen and retrofit damaged reinforced concrete beams. In general, the bond between the FRP element and concrete defines the effectiveness of the externally bonded FRP materials. In most cases, the interface bonding behaviour is usually tested via static loading conditions. In this paper, the bonding is verified under dynamic conditions. Wave propagation is modelled in delaminated CFRP strengthened reinfo [...]

Enhanced Long-term Antithrombogenicity Instigated by Covalently-Attached Surface Modifier on Biomedical Polymers

Received: 03 May 2020;  Published: 18 August 2020;  doi: 10.21926/rpm.2003019

Abstract

During a variety of medical procedures such as renal dialysis, bypass surgery, and lung transplantation patient blood is exposed to the surface of a number of polymeric materials such as polycarbonate (PC), poly (vinyl chloride) (PVC) and polysulfone (PS) for a period up to several days. Such exposure may result in undesirable protein-material interactions that can potentially trigger deleterious biological processes including thrombosis, which may be responsible for other complications such as [...]

Using Acoustic Fields to Fabricate ECM-Based Biomaterials for Regenerative Medicine Applications

Received: 22 March 2020;  Published: 21 July 2020;  doi: 10.21926/rpm.2003018

Abstract

Ultrasound is emerging as a promising tool for both characterizing and fabricating engineered biomaterials. Ultrasound-based technologies offer a diverse toolbox with outstanding capacity for optimization and customization within a variety of therapeutic contexts, including improved extracellular matrix-based materials for regenerative medicine applications. Non-invasive ultrasound fabrication tools include the use of thermal and mechanical effects of acoustic waves to modify the structure and f [...]

Bio-Based Substances from the Compost of Bio-Waste for Decontamination of Waste Water

Received: 25 April 2020;  Published: 01 July 2020;  doi: 10.21926/rpm.2003017

Abstract

A literature survey shows that the valorization of urban and/or agricultural biowastes into chemicals has caught the attention of experts and is gradually becoming quite an important issue. This review presents the application of the Bio-Based Substances (BBS) isolated from the compost of bio-wastes from urban gardening and park trimming residues. The non-cost BBS has been well studied in the literature. BBS are biological macromolecules with a complex lignin-derived structure containing several [...]

Dirac's Spectrum from Newton’s Laws in Graphene

Received: 17 March 2020;  Published: 01 July 2020;  doi: 10.21926/rpm.2003016

Abstract

The present report provides a phenomenological theory for monolayer graphene, in which two worlds, the quantum and the classical, meet and complete each other in the most natural manner. In the present report, electron mass-vortex representation is introduced, and the surface tension excitation states in the monolayer graphene are defined. The band-mass of the electrons at the Dirac’s point was calculated through the mathematical introduction of a mass-dispersion relation. As a consequence, the [...]
