The optimal emission intensity was observed at 1.0 mol% Sm2O3, highlighting the potential of these glasses for applications in green-orange-red emitting materials.
The obtained materials, particularly the one containing 0.8 mol% samarium oxide (Sm2O3), are good optical filters.
The raw materials were in the powder form 98% and supplied by Sigma-Aldrich.

Foundation and connecting frame are general parts, so their materials have nothing to do with dimensions of the device.
Thus, in calculating materials, considerations shall be given to length, width and height of the structure and then to the materials required by the foundation and connecting frame.

Because the anode materials are expensive, and will cause high energy consumption, low mechanical strength, short service life and other issues, the development of new anode materials are the future research direction and hotspot of anode materials.
PbO2 and MnO2 are non-noble metal oxide materials.
Anode materials obtain both advantages has been studied by Soviet Union, which have not been reported yet.

Effect of Melt-casting Temperature on Bonding Zone of CuNiMnFe/30CrMnSi Integral Material Juntao Zou1, a, Yanfeng Liu2,b, Xianhui Wang1, c, Shuhua Liang1, d 1School of Materials Science and Engineering, Xi’an University of Technology, Xi’an 710048, China 2Department of Chemistry & Chemical Engineering of Shangluo University, Shangluo726000, China azoujt077@163.com,bstilllyf @126.com, cxhwang693@yahoo.com.cn, dliangsh@xaut.edu.cn Keywords: CuNiMnFe, 30CrMnSi, Vacuum melting and casting, transition layer, bonding interface Abstract .The effect of melt-casting temperature on the microstructure and properties of transition interlayer for CuNiMnFe/30CrMnSi material was investigated in vacuum condition.
Experiment; materials and methods The 30CrMnSi low carbon steel and CuNiMnFe alloy(19-21wt%Ni, 19-21wt%Mn, 4-5wt%Fe) were used as joined materials. 30CrMnSi and CuNiMnFe alloy were placed into a graphite crucible in sequence, followed by melting and casting in a ZRS-18Q vacuum sintering furnace at 1090℃-1150℃ under the vacuum of 1×10-2Pa.
The melt-casting temperature is vital to the diffusion bonding of dissimilar materials and its bond strength.
No harmful brittle phase is formed at the transition layer, and the two materials have a good metallurgical bonding.

Introduction The discoveries of fullerenes and carbon nanotubes have resulted in exciting further developments in the nano-science and nanotechnology of carbon materials.
In the last decades, many differently shaped carbon materials have been synthesized and characterized [1-2].
It can be said that the term of carbon spheres refers to all carbon materials that possess a spherical or near spherical shape but do not include the fullerene family of carbons.
The preliminary electrochemical measurements of CNSs as anode materials of lithium secondary batteries were investigated via two-electrode coin-type cells.

As the computer science is developing rapidly, the search of technology of graphs has emerged in logic, linguistics, chemistry, electronics and some other fields of science.
A general introduction of breadth-first-search In computer science, graph theory occupies an significant position as it supplies simple but systematic modeling methods to a great number of problems.
The basic law of this algorithm has been introduced in a number of teaching materials.
