Preparation of Porous Multi-Channeled Chitosan Conduits for Nerve Tissue Engineering Q.
Materials Chitosan (degree of deacetylation = 83.7%, Mη =1.8 × 106) was purchased from Qingdao Haisheng Co (China).
Neuroblastoma cells (N2A, mouse) were used to evaluate the nerve cell affinity of the materials.
The results demonstrated that the Multi-channeled chitosan conduits were desirable for the application in nerve tissue engineering.

Decision Model in Selecting Engineering Materials for Pump Manufacture Joseph W.K.
Introduction Proper selection of engineering materials is one of the main causes for higher product performance and the economy of manufacture.
The decision on selecting appropriate engineering materials for a specific application can be a difficult task and usually a time consuming process.
This has a major drawback by overlooking any new engineering materials available in the market.
The potential engineering materials for pump production are: titanium (Ti), nickel alloy (Ni), 316 stainless steel (SS), martensitic stainless steel (MSS), and cast iron (CI).

These design features offer a great range of possibilities for research seeking to derive engineering principles from natural systems by adapting these principles for the improvement of man-made systems.
Woods were selected as raw materials.

The paper presents details concerning the basis of the technology, process parameter settings and their responses, and reviews the properties of common FDM engineering/bio-materials and the available methods applied for improving their performance.
Improving the polymers is essentially based on the correct selection of additive materials, which can particularly enhance the key property/properties in the matrix material.
FDM materials Based on the field of the application FDM materials can be classified into two brands; engineering and medical materials.
Engineering FDM materials By tracking the current technical characteristics of FDM technology, it will be noted that there are some limitations that restrict the variety of material which can be processed by this technology.

Introduction In the past two decades, smart materials have gained significant applications in various engineering practices (e.g. smart structures, nondestructive testing devices, electronic devices, sensors and actuators).
Complexity of smart materials is due primarily to the coupling feature of the governing constitutive law.
Three well-known classes of smart materials that commonly encounter in applications are piezoelectric, piezomagnetic, and piezoelectromagnetic materials.
Materials in the first class (e.g.

During the past decade, γ-PGA has been used as a material with fine swelling ability and biocompatibility, which makes it suitable for use in such clinical fields as BioGlue, drug or gene delivery systems [6-7] and tissue engineering[8-9].
Materials and methods 2.1.
Materials γ-PGA-H+ (γ -PGA, average Mw500kDa) were supplied by Guangdong DEMAY biological Technology Co., Ltd.
MTT (3-(4, 5-dimethyl-2-yl)-2, 5-diphenyltetrazolium bromide) was purchased from Shanghai Sangon Biological Engineering Technology & Services Co., Ltd (China).
The faster degradation of γ-PGA/β-TCP scaffold might be due to addition of γ-PGA into the scaffold materials.
