Анотація: (English) New design concept of FAD, include the device security requirements of Dor Chemicals and other companies; The dimensions of the device are extremely small; In the picture, in real scale factor is demonstrated FAD – 30 with maximal fuel flow = 285 liter per hour Today’s internal and open combustion systems (engines, boilers, turbines, etc.) are only as effective as the fuel used in the process. Today’s fuels are sub-optimal in three ways; they are not homogenous, they are limited in their blending options and they require significant amounts of added oxygen during combustion to complete the process. Turbulent Energy has designed, prototyped and tested technologies, which can be packaged, scaled and integrated with all thermodynamic combustion systems to improve liquid fuel characteristics and therefore improve combustion. Liquid fuels including distillates and synthetics are often not entirely homogenous at the time of distilling or blending and often loose their homogeneity over a period of time. Clotting and phase separation can occur and the fuels performance characteristics are degraded as a result. This change in the fuel’s composition can also hamper the combustion process and cause damage to fuel system components. Non-chemical methods are needed to ensure fuels are uniform and the combustion process is not compromised. In addition to ability to homogenize today’s standard fuels (gasoline, diesel, kerosene, etc.), Turbulent Energy can also “blend” those fuels while homogenizing them to create “new” fuel composites (i.e. emulsions). Completely uniform and homogeneous oil-in-water and water-in-oil emulsions are possible with any liquid fuel, including heavy fuel oil.

Анотація: (English) This article considers the problem of traditional use of nickel in jewelry production, associated with the risk of allergic reactions, and presents a comprehensive solution based on the development of an innovative nickel-free alloy with gold plating. A review of the literature demonstrates that nickel, used to provide luster and strength to products, can release ions upon skin contact, leading to allergic contact dermatitis. The present study is devoted to the development of a new composition that excludes nickel, while maintaining the necessary mechanical and aesthetic properties, as well as the technology of gold plating with the formation of a protective barrier layer, which ensures the hypoallergenicity of the product. The obtained results, confirmed by X-ray fluorescence analysis (XRF) and certification from “UKRCHIMANALIZ” LLC (2020), indicate the complete absence of nickel and the coating resistance to corrosion, which meets modern regulatory requirements (EN 1811, REACH). The scientific novelty lies in the integration of environmentally friendly materials into jewelry production through the creation of a unique nickel-free alloy capable of meeting the requirements of safety, aesthetics and functionality.
