As a result, biodegradable latex films with higher protein content is developed and introduced, in which this materials degrades rapidly through bacteria activity.
However, most of the research only focuses on bacterium activity on random material such as dye and feather.

New materials are needed in order to create an interface between microdevices and living tissues.
Equally important is the ability to resist excessive protein deposition on the material of the membrane.
BSA is well known to be a "sticky" protein and is commonly used to coat non-biologic materials in order to passivate them.
I 125-labeled BSA adhering to the membrane was measured using a Packard Cobra-II Autogamma (PerkinElmer Life Sciences, Downers Grove, IL) gamma counter.

Molecular chains of polymeric materials are entangled each other (Fig. 1).
The elongation of polymeric materials is very localized deformation.
The polymeric materials are separated the concentrated part and elongated chain parts.
Therefore, fracture stretch ratio of polymeric materials does not decrease as soon as UV irradiation.

For brittle materials, γ falls between 10-2 and 10-1 J/m2.
Materials and Methods The alumina utilized was obtained from Treibacher Scheifmittel, which is similar to APC - 2011 SG from ALCOA.
If the material is stronger, then its microhardness should also increase since the material penetration resistance becomes higher [6].

Introduction When creating new materials with specified functional properties, both the technology of their synthesis and the methods of non-destructive high-precision and high-speed control of the physical properties of such materials play an important role.
In particular, when creating modern microwave devices, nanoelectronics devices and spintronics, there are technological problems in setting and controlling the imperfection of the crystal structure of ferromagnetic materials.
The scale of this problem is such that the developed technique for modeling a multilayer ferromagnetic medium can be applied to any ferromagnetic, semiconductor and dielectric materials for analysis on any ellipsometric equipment.

Introduction Product manufacturing system is a systematic process that utilizes machines, materials, operators, methods, measurement & inspection and other process elements to make raw materials, semi-finished products into products.
But the mission reliability of manufacturing system is related to machines, materials, operators, methods, measurement & inspection and other process elements.
Ignore the very low probability events of natural disasters, material shortages,etc.
Assumed the input quantities of the raw materials or semi-finished products for the concurrent subsystems are equal proportional, the lowest mission reliability of the concurrent processes determines the comprehensive mission reliability.
Assumed the input quantities of the raw materials or semi-finished products for the Part A machining process, Part B machining process and Part C machining process are equal proportional, the mission reliability of the machining system is shown in Eq. 6

Wheel/rail Material Parameters In order to consider the plastic deformation of the wheel-rail contact area, a bilinear kinematic hardening elastic-plastic material model for the wheel-rail materials is used, and Mises criterion also is used to set the yield condition.
Rail material is U75V in China’s railway, and other material parameters are in Table 1, ρ is the density of the rail, ν is Poisson's ratio of the rail.
In addition, the material of the rail and the wheel is the same.
