The resulting catalyst shows equal or even better performance as Pt catalysts. Following the patented procedure of synthesis, the catalyst produced has a lower particle size. This leads to higher surface per particle and therefore, a better ratio yield when interacting in oxidation reactions, leading to a higher oxygen production rate.

Designed reactor allows the direct removal of nitric oxide from the exhaust gases via the efficient decomposition of nitric oxide and, at the same time, systematic removal of carbon particles and other solid particles.

The main sources of the methane emission are: exploitation of oil pools, coal mining, pas power stations, landfills, agriculture and biomass. The most popular method of the reduction of methane is its catalytic combustion. Unfortunately, this method has few limitations associated mainly with hard activation of the C-H bond in CH4 and low concentrations of methane in the emitted gases. The catalytic oxidation of methane is limited also by the very large airflows (of order 105 m3/min), passing through the catalyst bed during the process. There is still a lack on the market of a technological solution based on total catalytic combustion of CH4 in the economically reasonable low-temperature window, i.e. below 400 °C. The most popular method among the methods limiting the emission of methane to the atmosphere is the one based on its catalytic combustion. However, this procedure has disadvantages, mainly due to the high activation energy of methane molecules and also because of the low concentration of methane emitted from anthropogenic sources. There is no technology allowing effectively combusting of methane with the concentration of 1-2 % and in the economically justified temperatures, i.e. lower than 400 °C. The fundamental advantages of offered solutions are: - method for preparing catalysts that ensures the repeatability of the parameters and high efficiency in the reactions of methane combustion, - increased both the activity and the thermal stability of the catalysts in comparison with other systems described in the literature, - possibility of using the catalysts in the total oxidation of methane emitted from the low-caloric sources at temperatures below 400 °C.

Experimental studies, both in the laboratory scale and in the pilot plant at the Fertilizers Research Institute in Puławy (Poland), carried out for several prototype catalysts confirmed the high catalytic activity of materials offered. These studies consisted of: •passing a mixture of nitrous oxide and helium through the bed of a catalyst placed in a quartz reactor, •passing a tail gases from the pilot plant of nitric acid manufacturing, characterized by the same composition as the tail gases in the real industrial plant, through the catalytic system, and then determining the tail composition after reaction. The degree of decomposition of dinitrogen oxide in a mixture of N2O and He, at a temperature of 300°C was 95%, while decomposition products were only molecular nitrogen and oxygen. The pilot plant at a temperature of 350°C revealed the degree of decomposition of dinitrogen oxide was higher than 90%.

This product is integrated in a bicycle wheel. The basic concept of the product is using the rotation of the wheel, combined with the axial motion of the bicycle to push air through the filter material, thus filtering the air. The device itself is actually quite simple, and it has a goal of helping towards the solving the problem of air pollution in urban areas. Everyone who has a bicycle is a potential user of the product, but the users that would benefit the most are people living in urban areas that face the problem of air pollution. The best possible way to implement this device is to integrate the filters on bicycles sharing or renting systems that have a significant number of users, for example such systems are common in East Asia. Another way to implement the product is offering it to people as a product that can be added to their bicycle while buying a new one, or fixing their old bicycle. With all of the statements above, the ideal partnership would be with a company, but it is not exclusive to other companies, that works in the mentioned fields. The partnership could be via licensing the product, or selling the rights together with the complete documentation.

It converts a vehicle engine into an air pump during decelerations. It harvests the braking energy and stores it as compressed air for subsequent use to restart the engine in stop/start operation, saving battery and starter motor life. It also saves fuel as the compressed air also assists the normal engine-driven air compressor. Furthermore it can enhance the turbo thus reducing black smoke during acceleration from stationary
