Second, through the creation of specialized undergraduate research funds, students do their own project leader, taking the initiative to link science and technology instructors.
This gives a higher requirement of the reform and construction of the university library, library network system, international journals and reference room.
This present cross-campus of many disciplines, scientific research projects can share with each other, and also avoid phenomenon of duplicate investment and projects and material resources waste in the construction of various colleges, laboratories and research centers.
With Social progress and development of science and technology, education reform is urgently needed to develop creative talents.

A large amount of hard and strong cementite phase provides the material with high abrasive and hydro-abrasive resistance, high hardness, and medium strength.
Methodology and Materials Base alloys (Table 1) were prepared by the fusion of ARMCO-iron and electrode graphite in a high frequency induction furnace MVP-3M.
Naturally, the search for its genesis is an actual task for the materials science of eutectic alloys.

Nowadays, nanomaterials (nanotubes, nanoparticles, mesoporous material) were also considerable studied for therapeutic drug delivery.
It was well known that conventional administration of chemotherapeutic drugs is often compromised by the lack of selectivity, inability of drugs to overcome cellular barriers [13] and lack of clinical procedures for overcoming multidrug resistant cancer [14], and nano-materials sound an excellent choice.
The conclusion can be achieved: (1) SWCNTs are more reactive than MWCNTs, thus far the SWCNTs can be easier degraded and less cytotoxic in the cell. (2) The thinner diameters (~0.5nm) make the SWCNTs easier to overcome cell membrane barrier and this property may make SWCNTs a better drug delivery materials than MWCNTs.
