Cracow University of Technology posted this:The synthesis of silver nanoparticles suspension and nanosilver suspension in reductive system with urea for agrochemical and sanitary applications.The main advantage of proposed technology is the presence of urea in the system used commonly as a fertilizer promoting the growth of plants and both antifungal and antibacterial activity against pathogens. It also fits into the current trend towards the use of proecological technologies in industry. The resulting nanoparticles can be used in many industries, but the biggest potential lies in the agrochemical industry.

Universidad de Alicante posted this:Method for recycling of vessels and other structures composed of fiberglass and resinResearchers at the University of Alicante have developed a method to recycle composite fiberglass structures on a polymer matrix (resin). The process removes the polymer matrix, recovering glass fiber which can be reused. The process is not aggressive with fiberglass. It takes place at room temperature and is able to recover all the fiberglass used. The method is industrially scalable and can be automated. Fiberglass composites and resin are widely used in the construction of boat hulls, tanks, wind turbine blades and many other applications. This method is a very important innovation for the sector and there was no effective method that allowed recovering and reusing these materials.

The method is also effective for coating nanoparticles of variable nature, with a thin shell (tens of nanometers) with composition identical to the hybrids. The materials have been successfully tested in the removal of chemical species in water at laboratory scale, in particular in the removal of organic pollutants dyes and pharmaceutical compounds. Other applications are being considered. The University looks for companies working in the environmental, pharmaceutical or biotechnology areas, or companies in the area of materials for licensing and / or future collaboration in developing new formulations and testing new applications.

The functionality is incorporated into the structure of the titania being protected thereby.
Universidad de Alicante posted this:Noble metal-free ceria-based diesel soot combustion catalyst, suitable for gas purification in Diesel engine exhaustsThe developed catalyst does not use Pt, which leads to a cheaper product. 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.
Universidad de Alicante posted this:New catalyst that eliminates efficiently chlorinated volatile organic compounds in gaseous streamsThe new mixed oxide catalyst of cerium-praseodymium (CexPr1-XO2) allow the efficient combustion of chlorinated volatile organic compounds (especially 1,2-dichloroethane). These new catalytic systems are able to work in gas streams at temperatures between 250-500 º C in an dynamic and continuous way without suffering a significant deactivation process. In recent years, environmental legislation has restricted the air emissions permissible levels, and particularly the emission of volatile organic compounds (VOCs) harmful for both the environment and human health There is a wide variety of VOCs, of different chemical nature (aliphatic, aromatic, oxygenated and halogenated compounds) and consequence of different emission sources (waste gases from chemical plants, soil and water decontamination, solvents evaporation , etc..), but 1,2-dichloroethane (DCE, C2H4Cl2) is the most lasting, dangerous and commonly used in industry (used, for example, massively in the process of polyvinyl chloride production and consequently chemical plants produce significant amounts of waste that require efficient treatment). Until a few years ago, VOCs were usually eliminated by thermal incineration. However, new legislation on VOC emissions has originated significant improvements on treatment technologies. This is the case of the catalytic oxidation that in recent years has shown its ability to destroy VOCs at temperatures below those used in thermal incineration and has also produced a significant reduction of secondary pollutants (nitrogen oxides). Currently, catalytic oxidation processes require heating large gas flows that contain a small amount of VOCs and put the gas in contact with solid catalysts that can either be • Those containing noble metals as active phase: they have a excellent oxidation efficiency, although their cost is very high and gradually lose their activity with the presence of chlorine in the reaction mixture. • Those containing transition metals: they have a lower cost and are more stable and durable, although less active than those containing noble metals.
Centre Technology Transfer CITTRU posted this:Hybrid photocatalysts based on nanoclays for water purification (environment-friendly method of water purification)Water contamination becomes a problem, which may limit civilization progress. The development of a universal and inexpensive method of water purification is very difficult, because it may contain pollutants of different nature, e.g. heavy metals, organic compounds (pesticides, chlorinated aromatic compounds, antibiotics and surfactants) as well as bacteria. The water purification methods currently in use are based on osmosis, ion-exchange, adsorption, ultrafiltration, distillation and photooxidation. Although multifarious, they have limitations, mainly connected with their high power consumption and low efficiency.

It is characterized by a high efficiency, sustainability and more economical than conventional technologies. • It is therefore a real promising alternative that offers a great business opportunity in the growing market of activated carbon regeneration.
Centre Technology Transfer CITTRU posted this:Catalyst for low-temperature decomposition of dinitrogen oxide in tail gases from a nitric acid plantLow-temperature catalytic decomposition of dinitrogen oxide, carried out by the developed catalytic system which is the subject of the offer, is much more favorable in comparison with other solutions because of: •lack of necessity to use any reducing agents; •relatively low operating temperature; •high catalytic activity in the presence of other components of tail gases (oxygen, water and other oxides of nitrogen). 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%.
