The technology in a nutshell
-
The process according to the invention allows the graphene layer to be transferred from the source substrate to the target substrate without the use of polymer support coatings.
-
This method guarantees a cleaner surface of graphene and no polymer residue on its surface. In addition, said procedure enables the transfer of the graphene to non-resistant acetone substrates, which is typically used to remove polymers. As a consequence, this significantly increases the possibilities of using graphene. In addition, there is no need for a special holder or any other complicated tools.
-
By applying the method, it is possible to transfer the unlimited shape of the graphene layers even to rough and developed surfaces such as nanowires or materials finished with nanoparticles.

The technology in a nutshell
The present invention relates to a photonic crystal fiber for transferring radially polarised light beam and a method of manufacturing such a fibre.
In this technology a core is made of glass and a photonic cladding surrounding the core comprises nanoholes filled with air or nanorods. The core contains nano-inclusion made of glass or metal. The presence of nano-inclusion introduces birefringence, which causes narrowing of fundamental mode-field area and significantly impedes the excitation of the fundamental mode. This allows to couple and transmit radially polarised light.

Espacenet: https://worldwide.espacenet.com/patent/search/family/060674045/publication/EP3339261B1?q=EP3339261b1
The technology in a nutshell
The invention relates to a method of manufacturing an active optical fiber, called nanostructuring, in which the fiber core is composed of a few thousand subwavelength rods with similar diameters ordered in the hexagonal lattice. When the rods are made of two or more types of glasses with different refractive indices, their distribution determines the local refractive index experienced by a light beam.
Nanostructuring allows to obtain any gradient arbitrary refractive index profile if the size of a single nanostructured component is much smaller than the wavelength, i.e. λ/5. In active fiber, at least one type of glass is doped with rare earth (RE) ions.

https://worldwide.espacenet.com/patent/search/family/079021691/publication/EP4030624B1?q=pn%3DEP4030624A1
The technology in a nutshell
The subject of the invention is an electrical system for a self-disinfecting touch keyboard with a cold plasma generation function. In short, in the keyboard system, the air is subjected to an electric field exceeding the breakdown voltage (3kV/mm), but there is a dielectric layer on the high-voltage electrode that prevents the arc from igniting. The resulting electric field ionizes the air and produces reactive oxygen species, particularly atomic oxygen and ozone, which have the ability to deactivate microorganisms. Presented solution is based on ceramic technology and can be used in all kinds of terminal devices containing at least one touch key.
Thanks to the use of a cold plasma generator in the touch keypad, the possibility of killing a wide range of harmful human pathogens and chemicals is created, which, considering the consequences of Covid-19 pandemic, is of great importance. Used ceramic technology in our solution is well-suited for making plasma generators and its features such as chemical inertness (no corrosion) and good dielectric strength make it even more interesting in relation to current solutions on the market.

The technology in a nutshell
Our patent presents a method of measuring the pressure of the foot on the ground, especially under conditions of physical human activity, such as walking, running or jumping. Measuring the pressure exerted by the foot on the ground under dynamic conditions makes it possible to get a good understanding of the mechanics of the foot’s work and to assess the correctness of its structure.
The main advantage of a system incorporating the measuring insert according to the invention is the ability to conduct tests in natural non-clinical settings, such as during home activities, exercise and field stays. The low cost of manufacturing our insert means that it can be made in many sizes and large quantities.
