Thermally stimulated depolarization current (TSDC) results indicate that there are two types of shallow traps in the composite, 0.52eV and 0.62eV with trap densities 1.2×1010/cm3 and 2.0×1011/cm3, which differs significantly from that of pure SP (0.58eV, 3.1×1010/cm3).

A new dielectric loss peak was found near by 2MHz at room temperature for the sample in the absence of Bi2O3, the corresponding electron trapping level was about 0.18 eV, it was considered that the loss peak resulted from intrinsicdefect Zni .
1. New promoter trapping vectors pEGFP-HPH and pCB1003-EGFP have been constructed which possess the marker hygromycin gene and a promoterless eGFP gene;
In 1879, A. B.Kempe succeeded in proving Four-color Conjecture when d(v)=2,3,4, but the neglected much complicated situation (pitfall configuration) when d(v)=5 and the central area is A placed between B and B .
There were 50.1 individuals captured per pitfall trap in cotton field adjacent to cotton field,which was less than that in cotton field adjacent to wheat/corn(75.1 individuals) or alfalfa field(77.6 individuals).
After the issue of velocity pitfall in this area was solved in 2001, the seismic data were reprocessed through 3D pre-stack depth migration, structural shapes were materialized, oil - bearing area increased from 3.0km 2 to 5. 6km 2, and proved reserves enlarged from 2.13 million tons to 3. 37 million tons.
We propose a mechanism on the increasing PL emission in the above structures, in which the trap state of the interface between SiO2 and nanocrystal plays an important role.
Full two-dimensional control of multiple ions on an ion chip is promising for the realization of scalable ion trap quantum computation and the implementation of quantum networks.
The results indicate that the original number of OSL traps that have captured electroncs is linearly related with the sum of TL decay during the OSL process.
Pool elements, such as preservation conditions, traps and migration paths, and reservoir rocks and facies, also served as important control factors to marine gas pools in South China.
We have used a direct method for free radical detection, EPR of spin trapping, and the following spin traps: N-tert-butyl-α-phenylnitrone (PBN) and α-(4-pyridyl-1-oxyl)-N-tert-butylnitrone (4-POBN).
The study of the rate of generation by pea mitochondria using EPR spin traps and epinephrine oxidation showed that H2O2 accumulation can be accounted for by a significant increase in the rate of production.
It is emphasized that a strong CTC is able to provide effective trapping of electronic excitation energy from antenna chlorophyll, which is a main function of the RC.
