A number of different metals and metal oxide nanoparticles have so far been encapsulated into the shell of conducting polymers, giving rise to a host of composites [5–6].
As the CeO2 concentration increases, the compactness of the sample increases causing coupling through the grain boundaries to become stronger which could enhance the conductivity.

The introduction Jilin province is a Chinese herbal medicine planting and production big province,has rich resources of Chinese herbal medicines.The province has a total of nearly 2800 kinds of medicinal biological resources with ginseng,American ginseng,deer,and as a byproduct of Chinese herbal medicine with green,famous and renowned at home and abroad[1].In the research and production of long-term practice,the agricultural science and technology personnel and agricultural production managers for ginseng production,management has made a number of achievements in scientific research,and has accumulated rich experience,but because ginseng production scale in our country is not a,and high dispersion,high levels of agricultural experts,agricultural scientific and cultural quality.The relatively low,dissemination of science and technology is relatively slow,the cultivation and management of ginseng are the problems to be solved.Especially with the development of information technology and

The diffraction profiles reveal that all the Sm-doped BiVO4 powders are well-crystallized and the broad diffraction peaks imply that the crystalline grains are on nanoscale.
The high-magnification SEM image shown inset in Fig. 2b reveals that the peanut-like nanostructures composed of a large number of nanoparticles and with porous structure.

Weld joint strength decreases if the number of melts grows as a result of the change of explosion welding parameters: impact velocity, collision velocity and the masses of the plates to be welded [4 – 7].
Next there is a decarbonized zone with the grains elongated in the direction vertical to the joint boundary.

It is known that some complex media such as sands and rocks exhibit strong nonlinear acoustic phenomena, due to the weak bonding between micro-grains [1].
While a number of investigations have been reported on the nonlinear stress-strain behavior of C/C composites due to micro-damage developments, e.g. [5], the present findings show that this material also exhibits significant nonlinearity in dynamic processes such as ultrasonic wave propagation.
