LIKE NO ONE ELSE
Adianano is a deep-tech start-up operating in the field of nano-material production. The company has invented a novel approach in developing high quality nano-silicon and low-layered graphene. This technology is able to drastically increase properties of many materials in different industries, such as lithium-ion batteries, production of plastic materials, automotive and etc.
The method is based on the concept of obtaining nanopowders by initiating the synthesis of the target products (gases) via rapid and uniform temperature rise throughout the volume of a reactor filled with a mixture of gaseous precursors. For example, the adiabatic compression of a mixture of silane and acetylene with a buffer gas can result in an increase of the temperature above the decomposition temperatures of these reactants, leading to the synthesis of nano-silicon (Si) and it’s compounds in the solid phase.

Can be tuned precisely over a very broad range depending on the processing and end use performance requirements
Method of graphite intercalation via microwave exfoliation produces graphene platters with the average stacks thickness that are three times lower and the resulting “low-layer graphene” is less defective than graphene produced using other methods. Further graphene layer split can be done using ultrasonic treatment of the “low-layer graphene” in organic media.

Silicon is the alternative to graphite as an anode material for lithium-ion batteries. Its theoretical specific capacity of 4212 mAh/g, while the theoretical value of specific capacity for graphite is of 372 mAh/g. Currently, graphite is used in lithium-ion batteries due to its good electrochemical conductivity (372mAh/g) and ability to withstand large number of cycles. The high initial capacity of composites based on silicon rapidly decreases with cycling, which is associated with the increase of silicon volume at more than 300% under the process of its lithiation-delithiation.Volumetric changes can be somewhat compensated by the use of nanostructured silicon in composites with conductive carbon nanostructures (low-layered graphene).
Coatings & Tribology
Coatings – protective coatings on glass and plastic surfaces
Graphene, which is hexagonally-oriented carbon, is atomically-thin, incredibly strong (comparable to diamond), gas impermeable, and chemically and thermally stable. These qualities make it an ideal protective coating. Since graphene was only isolated in the past decade, and only produced at macro scale in the past five years, its potential has only just been explored. As such, it is imperative that further study on graphene’s tribological behavior, and potential applications be conducted.
Adianano is experimenting with implementing its materials into different polymers (plastics). The outcome of testing showed that it is possible to improve properties like – breaking strength, elongation at break and hardness of the material. Initial testing was conducted on polyurethane. Those tests showed that there is a potential application of Adianano material in the sector of “Physical properties improvement of different polymers (plastics)”.
Potential sectors could be – the automotive industry, protective gear, construction, pipes, aerospace, electronic cases and etc.
In addition, another potential application of improving properties of polymers could be using this method to restore properties of already recycled polymers. Thus, using them in the same field for more than one time, where criteria of the condition of the material are critical. This will lead to a circular economy and increase sustainability.
