Towards a Li-air battery

ID: F1510-06

A Li metal anode as an alternative of graphite and the use of oxygen (O2) from the atmosphere as a cathode guarantees up to 10 times greater energy thickness. However, O2 decrease following response with Li-ions leads to deposition of a solid item within cathode porosities and to cathode clogging. Scientists addressed this problem with a radical approach perhaps not yet tried. Traditional metal-air batteries, as well as fuel cells, rely on three-phase contact points inside the cathode. The connections guarantee electron transport, hydrogen transportation and O2 influx. Nevertheless, in the situation of Li-air, this operating configuration changes the porosity and hydrophobicity of the cathode because of the development of the reduction products at the three-phase contact points. In groundbreaking studies, the group investigated a two-phase contact-point electrode setup (a flooded setup). The electrolyte or charge carrier is also used as the O2 carrier to harvest O2 from ambient air through an outside O2 harvesting device. The idea employs environmentally benign ionic liquid electrolytes and nano-structured electrodes that harvest dry O2 from the atmosphere. Experts ready and tested anode and cathode materials, developed the O2 harvesting concept, and prepared and integrated into the electrode systems numerous ionic liquids as well as solid polymer electrolytes. Fundamental studies provided physicochemical parameters for the model of a complete Li-air battery pack. Although the useful execution of Li-air batteries is not anticipated for another ten years or two, LABOHR has made a major share to the development work. Studies confirmed the value of utilizing ionic liquid-based electrolyte solutions to deal with solvent reactivity and volatility issues, and highlighted the issues of operating the Li-air battery in three-phase configuration. The idea of soluble redox ‘shuttle’ also opened a new possible course toward useful Li/O2 battery. In the meantime, the studies of electrolytes and electrode materials are most likely to discover short-term application in the Li-ion battery field.

    Exhaust air without organic chemicals

    ID: F1509-09

    Volatile organic compounds (VOCs) such as benzene and styrene can be hazardous to our wellness since well as the environment. Researchers are working on removing VOCs from commercial atmosphere emissions with the use of biotechnology. Three institutions have joined forces to eliminate VOCs from polluted industrial air emissions under the umbrella of the THEN AIR BIOTREAT project. Analysis collaboration led to the successful development of a novel hybrid biotechnology for treatment of hydrophilic VOCs. This set-up has been upgraded to industrial scale with a model product presently under operation. Definitely promising preliminary results have resulted in a patent. A pilot biotrickling filtration device had been set-up demonstrating efficient elimination of styrene from air emissions. From a financial and environmental point of view, this set-up proved superior to other technologies such as regenerative thermal oxidiser and activated carbon. Empirical information on filter overall performance has been generated to develop a mathematical model and control software to further optimise this technology. Researchers are currently testing a serial system incorporating a photocatalytic and biotrickling filter. In parallel, project members are developing a networking information platform for information processing and tracking of biotechnology systems. The project has advanced understanding of bioprocesses for VOC elimination from polluted air. Commercial exploitation of developed technologies will enhance the competition and visibility of participating institutions and promote the jobs of the scientists included. This has significant implications with respect to improving health and protecting the environment.

      New air cleaning technology

      ID: F1509-02

      Industrial environments produce a great deal of dust that can be damaging to both equipment and personal health. A brand new air cleaning system that removes nano-scale particles and prevents build-up of explosive dust will tap large global areas. Experts therefore created an improved industrial-scale air cleansing system. The system is compatible using the European Commission's Potentially Explosive Atmospheres (ATEX) Directive. It's also aligned with standard programs in a variety of industrial manufacturing outlines. Software tools to model the spatial and temporal separation characteristics given interior dirt concentration for a variety of complex situations supported the effort. The tools also enable evaluation of components and reliability. One of the absolute most crucial innovations spurring task success was splitting the deduster housing into two compartments. The first cleans the high-volume, low-pollutant concentration air stream. As filter cake builds up, it's periodically removed with suction to minimise accumulation of explosive dust. The filter cake is transported to the second compartment and subjected to low suction. Division into two compartments and use of ignition source and spark tracking significantly decreases the risk of explosion. The filter itself is a traditional drum filter, but it employs a novel fibrous textile material. The drum filter enables more controlled filter regeneration (elimination of build-up via suction) and very low force loss. Its pleated design supports dust separation down to the nano scale. The specialised textile material supports extremely high filtration prices. The pleated filter drum design and filtering process are entirely unique and have actually resulted in a patent application. Design and construction of the very first demonstration product had been approved by the Notified Body tasked with evaluating conformity of a manufacturer's air cleansing unit with essential demands regarding safety and avoidance of explosion threat. The demonstrator had been employed for a four-month period on a factory flooring. Its conformity with regulations will get rid of the need for explosion-proof instrumentation, significantly reducing costs for manufacturers. Mobility, reduced power consumption and the capability to filter nano-scale particles could make it also more competitive in the huge worldwide market exploiting nanomaterials.

        Finding oil in compressed airhttp://www.e-numberland.de/index.php/get-in-contact/item/1450-finding-oil-in-compressed-airhttp://www.e-numberland.de/index.php/get-in-contact/item/1450-finding-oil-in-compressed-airFinding oil in compressed air

        Finding oil in compressed air

        ID: F1504-06

        Whenever compressed to a smaller volume, atmosphere attains higher-than-atmospheric pressure that makes it helpful in many commercial and domestic programs. Τhat fοrce per prodυсt area can be υsеd to impаrt movement in pneυmatiс tools. Іt can additionally atomise or spray sυbѕtanсеs suсh as aυtomоtive coatings, рrovide аerаtion for oxidatiοn in pharmaceuticаl procedυres or clеan eleсtronics during рroduсtion.
        Thеse and other high-еnd applications rеquire very-high–purity compressed air. Oil contamination is a pressing issue and there is currently a lack of any dependable, highly delicate, online sensor system to deal with it. Researchers are offering the much-needed solution with a new real-time sensor system. It's going to identify oil in all its types (fluid, aerosol and vapour), ensuring conformity with laws and eliminating the dangers and liabilities linked with non-conformance.
        Optical spectroscopy hаs beеn сhοоsеn. It's the absolυte mοst promising technology to guаrаntee incrediblу high awarеness (meetіng ISO-8573 Class I standards of air quality), repeatability, robustness to intеrference and steаdy calibration. The sensor platform wіll соmprise of three υnitѕ: the sаmpling system, thе оptical spectroscopy unit, and the еlectronic devices and software.
        The samрling system featureѕ been desіgned and enablеѕ for non-invasiνe tracking of oil contamination in comрressed air flow. The optical spectrоscopу unit, рhоtoacoustic spectroscopy, іs prоgressing well. The technology rеlies on the emisѕion of soυnd (a force wave of thermal expansіon) in rеspοnse to аbsorption of electrοmаgnеtіc energy (lіght). It is relаtivеly simрlе and affordаble hоweνer very sеnsitive. Current develоpment is focuѕed on oрtіmising the techniquе аnd potеntiаlly increasing sensitіvity by a factor οf 10.
        Initіal results help success of a cοurse we оr much better sensor. A patent іs anticipаted. Lastly, electronісs for the sensor have beеn specified and software written.
