The results show that, based on Euclidean distance, tungsten and manganese are the two most important raw materials.
The study [3, 4] forecasts the energy demand across the entire battery value chain, covering the extraction and processing of key compounds such as manganese sulfate (MnSO4), the production of metals and inactive materials, etc.
The energy consumption per kWh of selected modern battery cells is estimated, as well as next-generation materials such as lithium-manganese, nickel-manganese-cobalt oxides (LMR-NMC), indicating the high potential for manganese applications not only in metallurgy, but also in energy generation, provided that high-quality raw materials are available.
The study [5] analyzed such minerals as lithium, nickel, cobalt, manganese, graphite, which are declared critical in the EU list of critical raw materials, taking into account their potential in the world.
The analysis discusses the security of raw material supply for an electric vehicle production plant in Turkey, and Ukraine, as the largest supplier of manganese raw materials in Europe, can become a reliable partner given its geographical location.

Introduction In contrast to amorphous silicon and other group-IV tetrahedrally bonded semiconductors, the chalcogenide glasses have a Kerr non-linearity a hundred times larger than that of silica [1], making them excellent and unique materials for the fabrication of devices for integrated and fiber optics.
The values of R are found to be greater than unity for glasses with chalcogen-rich materials, and less than unity for glasses with chalcogen-poor materials.

Their greatest advantage is their mobility, low weight, relatively high performances and quality processing materials.
The used technology of cutting and processing wood and wood-based materials as well as the used tool also, to a great degree, take part in production of dust particles.
From the viewpoint of primary dustiness, the proportion of the particles with the dimension ≤ 80 μm in diameter is very high as for all types of sanders and sanded materials.

Preparation and Research of α-Fe/montmorillonite Magnetic Material Cheng-cheng SHIa, Long-gui PENGb, Zhi WANGc (Department of Materials Science and Engineering, Xi'an University of Science and Technology, Xi'an Shaanxi 710054) alittlecheng2008@163.com, bpenglonggui@163.com, c2181345wang@163.com Key words: MMT, Hydroxyl-Fe, In-situ pillared-reduction, Magnetic property Abstract. α-Fe/montmorillonite(MMT)magnetic material was successfully prepared by the in-situ pillared-reduction method.
The preparation of hydroxyl-Fe pillared MMT have received increasing attention because of wide source of raw materials and low toxicity to environment, but it focused on adsorption or modification in the layers of MMT [2-3].
The application of magnetic materials in biology, medicine, electronic and other fields has opened up a new way for the future development of composite materials.

Space targets detecting oriented method of materials differentiating Shixue Xu1, a, Lingfei Xu2,b, Yanru Chen3,c 1,2,3Department of Optical Engineering, Nanjing University of Science and Technology, Nanjing, P.R.China 210094 aete_corner@yahoo.com.cn, bjsj900@hotmail.com, cyrchen2002@yahoo.com.cn Keywords: Space targets, scattering, polarization analysis Abstract.
We have inspected two kinds of materials which are widely used in the manufacturing of space vehicles and we have found similar optical information in the scattered light of the two kinds of materials, as the bio-reflection distribution, the spectrum distribution and so on.
In order t describe the reflection of given materials precisely, the bio-reflection distribution function (BRDF) is used for the intensity of scattered light is usually determined by the reflectivity of materials and the reflectivity of many kinds of materials will change along with the angle of incidence under most conditions.
Our research indicates that the optical differentiation of materials method will have more feasibility if we take more information from the scattered light of materials’ surfaces as the polarization variation tendency which is a remarkable characteristic when the two kind of materials with similar scattering characteristic are need to be distinguished, based on which, more simple optical detection system of space targets are feasible.

Thermal Management Materials The urgent need and demand for improved thermal management materials has resulted in many studies and researches currently carried out on potential materials.
Although the use of advanced composite materials as thermal management materials would incur additional costs, the improvements in thermal performance inherent in such materials make them cost-effective.
