Due to the rising emission of methane and its extensive contribution to the greenhouse effect, the reduction of CH4 emissions from low-caloric anthropogenic sources is currently a vital importance. 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.

Researchers at the University of Alicante have devised a system to partially absorb the energy generated in a crash involving at least one motor vehicle traveling at a high or medium speed. It is a passive protection system for vehicles which absorbs the maximum amount of mechanical energy in a crash with minimal added weight and volume. Assumes additional protection that enhances the vehicle's passive safety, minimizing the consequences of a collision for the passengers. The system has an innovative design that allows placing it in different positions inside the vehicle or making structural parts and is manufactured with advanced materials. Innovative aspects The system is designed to provide protection that goes beyond the current regulations for passenger cars, as it is able to absorb a larger proportion of the mechanical energy generated in a collision. Also improve the passive safety of vehicles (vans, trucks) or special vehicles (ambulances, fire trucks, armored vehicles) in circulation. It also provides substantial improvements for heavy duty vehicles, contrary to what is happening now should be able to absorb themselves much of the energy produced in a collision with a vehicle lighter, thereby minimizing the potential damage that may occur in people who travel light vehicle. The system consists in several stages which act consecutively on impact, absorbing energy in a gradual and proportional to the energy generated in the collision, which is a lower acceleration on passengers, thereby reducing the potential injuries. Less weight, volume and system size compared to traditional structural systems, through the use of advanced materials: tensile filaments that act in case of collision, thermosets broken links which act by absorbing the impact energy generated in the fiber and combined with high strength composite metal / polymer composite micro / nanostructures
