Nano Calcium-Deficient Hydroxyapatite/O-carboxymethyl Chitosan-CaCl2 Microspheres Loaded with Rhein for Bone Defect Repair
Journal of Bionic Engineering - Tập 19 - Trang 1087-1099 - 2022
Glutaraldehyde (GA), the most widely used crosslinking agent for biomaterials, is cytotoxic. CaCl2 is of particular interest due to its non-toxic nature. Rhein can chelate Ca2+ and promote bone growth. Here we reported a novel nano calcium-deficient hydroxyapatite/O-carboxymethyl chitosan-CaCl2 microspheres loaded with rhein (RH-nCDHA/OCMC-CaCl2 microspheres) using CaCl2 as crosslinking agent for ......
Anthropomorphism Indexes of the Kinematic Chain for Artificial Hands
Journal of Bionic Engineering - Tập 17 - Trang 501-511 - 2020
Anthropomorphic hands have received increasing research interest in the fields of robotics and prosthetics. But it is not yet clear how to evaluate their anthropomorphism. Similarity in the kinematic chain is essential to achieve both functionality and cosmesis. A few previous works have addressed the definition of anthropomorphism indexes, although they have some limitations in its definition. In......
Biomimetic hydrophobic surfaces with low or high adhesion based on poly(vinyl alcohol) and SiO2 nanoparticles
Journal of Bionic Engineering - Tập 14 - Trang 476-485 - 2017
Superhydrophobic surfaces are often found in nature, such as plant leaves and insect wings. Inspired by superhydrophobic phenomenon of the rose petals and the lotus leaves, biomimetic hydrophobic surfaces with high or low adhesion were prepared with a facile drop-coating approach in this paper. Poly(vinyl alcohol) (PVA) was used as adhesive and SiO2 nanoparticles were used to fabricate surface mic......
An Overview of PRP-Delivering Scaffolds for Bone and Cartilage Tissue Engineering
Journal of Bionic Engineering - - Trang 1-20 - 2024
Tissue engineering is nowadays an emerging approach that aims to replace or regenerate diseased or damaged organs with engineered constructs. Considering the key role of growth factors (GFs) in the tissue regeneration process, these biomolecules are considered an important part of the tissue engineering process, so the presence of growth factors in engineered scaffolds can accelerate tissue regene......

Multi-hop routing optimization method based on improved ant algorithm for vehicle to roadside network
Journal of Bionic Engineering - Tập 11 - Trang 490-496 - 2014
This paper proposes a route optimization method to improve the performance of route selection in Vehicle Ad-hoc Network (VANET). A novel bionic swarm intelligence algorithm, which is called ant colony algorithm, was introduced into a traditional ad-hoc route algorithm named AODV. Based on the analysis of movement characteristics of vehicles and according to the spatial relationship between the veh......
Design and fuel consumption optimization for a bio-inspired semi-floating hybrid vehicle
Journal of Bionic Engineering - - 2011
Based on a bionic concept and combing air-cushion techniques and track driving mechanisms, a novel semi-floating hybrid concept vehicle is proposed to meet the transportation requirements on soft terrain. First, the vehicle scheme and its improved duel-spring flexible suspension design are described. Then, its fuel consumption model is proposed accordingly with respect to two vehicle operating par......
Influence of CrN coating on electrochemical behavior of plasma nitrided pure titanium in bio-simulated environment
Journal of Bionic Engineering - Tập 13 - Trang 150-155 - 2016
Titanium and its alloys are widely used as materials for bio-medical applications, such as implants. However, ions of the alloy can release to the body region and spread into the blood circulation. In this study, plasma nitriding and CrN coating techniques are used in order to overcome the problem of ion release. The objective of this study was to investigate the effects of plasma nitrided pure ti......
Nanomechanical Behaviour of the Membranous Wings of Dragonfly Pantala flavescens Fabricius
Journal of Bionic Engineering - Tập 13 - Trang 388-396 - 2016
The dragonfly has excellent flying capacity and its wings are typical 2-dimensional composite materials in micro-scale or nano-scale. The nanomechanical behavior of dragonfly membranous wings was investigated with a nanoindenter. It was shown that the maxima of the reduced modulus and nanohardness of the in-vivo and fresh dragonfly wings are about at position of 0.7L, where L is the wing length. I......
Computation of unsteady flow past a biomimetic fin
Journal of Bionic Engineering - Tập 1 - Trang 108-120 - 2018
The unsteady hydrodynamics of a biomimetic fin attached to a cylindrical body has been studied numerically using a computational fluid dynamic (CFD) simulator based on an in-house solver of the Navier-Stokes equations, combined with a recently developed multi-block, overset grid method. The fin-body CFD model is based on a mechanical pectoral fin device, which consists of a cylindrical body and an......
