A: Yes , we could offer the sample for free charge but do not pay the cost of freight . Q: What is your terms of payment ? A: 30% T/T deposit , 70% balance by T/T or L/C before shippment. Q:Why did lots of customers choose us? An: Stable qu...
The layer of Fe3N could significantly decrease the variation of volume and enhance the conductivity of Fe3O4 simultaneously during the reaction of lithium ions in the charge-discharge process. There are two main advantages of this material: (1) their size distribution, ranging from 100 to 500...

The enhanced performance was ascribed to the separation and migration of the photoinduced electron–hole pairs and taking part of the charge carriers in the chemical redox reactions at the surface of the photocatalyst. In this work, the effect of Fe weight percentage on the degradation potential ...
The results of density of states, charge distributions and overlapping populations indicate that β -Si 3 N 4 has the strong covalent and ionic bond strength between N and Si.Long, MinSchool of Materials Science and Engineering, Chongqing University of Technology, Chongqing, China...
More importantly, the Fe_2 O_3-xSx nanoparticles formed intimate heterojunction with CNS and developed the efficient charge transfer by extending interfacial interactions occurred at the interfaces of both components. It has been found that the Fe_2 O_3-xSx/CNS composites have an enhanced ...
