Vacancy Engineering - an Ultra-low Thermal Budget Method for
High-Concentration 'Diffusionless' Implantation Doping
Nicholas E.B.
Source/drain (S/D) junctions formed by advanced vacancy engineering implants (VEI) are activated far above solubility.
In the vacancy engineering approach, boron is implanted into crystalline silicon that has been prepared with a high concentration of excess vacancies by a co-implant process.
The key to 'advanced vacancy engineering implants' (VEI) [4] lies in two features.

Abstract.
In tissue engineering field, porosity of scaffolds play key role for cell attachment, grow and proliferation consequently help in regeneration of new tissues.
Regardless of the type of materials the scaffolds are derived from, they need to meet several criteria for use in tissue engineering applications.
Materials & Experimental Materials Poly(ethylene glycol) diglycidyl ether (PEGDGE, Mn = 526 Da) were purchased from Aldrich and used as received.

It is crucial to choose the appropriate green building materials, because it acts as a key factor to the development of green building.
Until now, the building materials which have been certificated by ecolabel are only the hard floor materials (2002/272/CE) and indoor paints, varnishes materials (2002/739/CE)
(2) It has weak guidance to the materials manufacturers.

The key of green design is the "3R" principle, namely Reduce, Recycle and Reuse.
It means that environmental factors and engineering properties together serve as the goal of material selection.
Green material is the key and prerequisite of green product design.
Green product design asks for that materials selected can naturally degrade.
Selecting recycled material of the waste can reduce environmental pollution and save raw materials.

Scaffold materials for cartilage tissue engineering
The role of scaffold materials is not just to provide support and space for cell growth.
Based on their sources, materials used in tissue engineering studies can be classified as natural biomaterials and synthetic biological materials or artificial polymer materials.
Therefore, synthetic polymer materials have become important scaffolds in cartilage tissue engineering.
Synthetic polymer materials used for cartilage tissue engineering are mainly polyester-based materials, such as PGA, PLA, or PLGA and can be divided into non-biodegradable and biodegradable materials.
In recent years, new synthetic materials such PEMA/THEMA begin to apply in cartilage tissue engineering.
