ABsolutely "Universal" Powders For Selective Laser Sintering Importance of understanding the issue of using consumables for SLS machines is extremely high, especially for Russian clients. Difference in standards and close settings of 3D printers makes users highly dependent on material supplied by their machine producers. So, economic sanctions and currency valuation directly affects efficiency of newly developed Additive sites.

Alternative Of Future: High-Speed Laser Cladding Is Coming To Replace Hard Chromium Plating Risk of the prohibition of hard chrome metal components in European Union contributes to the development of new technologies and coating tools. Industrial approved gas-thermal evaporation has proven its flexibility, however, the quality of the applied protective layer is insufficient for many areas of the process. The real alternative to hard chrome plating and sputtering is an extreme high-speed laser cladding (EHLA), developed at the Institute of Fraunhofer ILT using Laserline components.

Influence Of Modes Of Laser Cladding And Composition Of Powder Materials On Abrasion Resistance Of The Coatings To extend the working life of the parts subject to abrasion, surfacing is widely used. Furthermore, the pad weld should have good adhesive strength to the substrate and contain minimum of defects. But which cladding technology should be preferred: electric, electromagnetic or laser one? The results of laser cladding research for different groups of machine parts and assemblies are given below. The characteristic defects resulting from wear of the surface of thin-film and thick-layers are defined.

Military Application Of Laser Technology Is Speeding Up And Beginning To Determine The Technical Level Of Modern And Advanced Weapons. Part 2: Review: Small And Medium Range Laser Defense Systems The efficiency of a weapon is determined by the time. Just as gunpowder replaced the knives and swords, combat lasers, acoustic and microwave weapons is coming today. Small and medium range battle air defense laser systems of foreign developers demonstrate high accuracy and efficiency, and the Russian developers have offered an alternative option - microwave weapons. Final conclusions about the characteristics of the laser and microwave weapons could be done only after comparative tests on landfills and in combat conditions.

High-Aperture Diffractive Lens For Holographic Printer In this work we suggest an optical scheme of the holographic stereogram with the viewing angle increased to 120°. The scheme is based on the joint use of the diffuser and diffractive optical element – high-aperture diffractive lens with a relative aperture of 1:0.3. The binary Fresnel – zone plate was used as high-aperture diffractive lens.

Displacement Currents In The Non – Conducting Dielectrics: The "Ugly Duckling" Becomes A Swan The key words in the title of this article shall be owed to two geniuses of the century before last: the term "dielectric" has been suggested by M. Faraday; "displacement current" has been introduced by D. Maxwell. The fate of these innovations was developing in different ways: at the end of XIX century the electric motors, lighting systems and emerging telephony has been using habitual conduction currents in metals; non-conductive dielectrics has got a modest but a useful role of insulators. In contrast, the "displacement current" seemed to be a mathematical phantom, inserted in one of Maxwell’s equations, in order to provide the continuity of AC line in a non-conductive medium. However, in actual electrical circuits this phantom was observed long before Maxwell, therefore a direct question "What is displaced in a displacement current?" had a long history.

Modeling Of The Electronic Properties Of Graphene Magnetic Heterostructures: Ab Initio Study Magnetism of defect-free graphene is a surprising phenomenon that deserves the attention of theorists and experimentalists, as it gives us a hope for the new discoveries of quantum effects in future. Within the framework of the density functional theory (DFT) we have simulated graphene electronic structure adsorbed on a magnetic insulator MnO (111), limited by oxygen. Interface of graphene heterostructure SLG/H:MnO (111) has been modulated by the degree of its hydrogenation. DFT-based calculation has been used to systematically investigate the local atomic reconstruction of the interface depending on the degree of hydrogenation. It has been shown that the electron spectrum and magnetism in the system SLG/H:MnO (111) can be modulated by the degree of hydrogenation of the oxygen interface layer, suggesting high potential for the use of this system in spintronics.

Intercellular Communication Using Coherent Radiation The distant intercellular interaction is the key to understanding the nature of so-called "biofields", which are deemed to be the connecting link between the information contained in genome and its implementation in morphogenesis process of multicellular organism. Experimental results of various authors illustrating the field (non-chemical) form of intercellular interaction using optical radiation are considered. The main contradiction of field communication of biosystems, which consists in the recognition of superweak signals of biochemical luminescence against the background of significantly more intense natural illumination, is determined.

Equipment And Methods Of Laser Rapid Analysis Of Petroleum Products The Russian market is filled with imitations of petroleum products, both oil and fuel, and the situation requires their prompt detection. We present a new complex method of laser phase rapid analysis of the properties and the quality of petroleum products. The method is based on analysis of phase transformations in the turbid liquid process medium when it is cooled to solidification and subsequent heating. On the basis of this method we have designed and manufactured an automated measuring system for rapid analysis of various types of liquid petroleum products.
