) The concept of e-noses - electronic devices which mimic the olfactory systems of mammals and insects - is very intriguing to researchers involved in building better cheaper and smaller sensor devices. A better understanding of the reception signal transduction and odor recognition mechanisms for mammals combined with achievements in material science microelectronics and computer science has led to significant advances in this area. Nevertheless the olfactory system of even the simplest insects is so complex that it is still impossible to reproduce it at the current level of technology. For example the biological receptors are regularly replaced during the life of mammals in a very reliable way so that the receptor array does not require to be recalibrated. The performance of existing artificial electronic nose devices is much more dependent on the sensor's aging and especially the sensor's replacement and frequently require a recalibration to account for change. Moreover current electronic nose devices based on metal oxide semiconductors or conducting polymers that specifically identify gaseous odorants are typically large and expensive and thus not adequate for use in micro- or nano-arrays that could mimic the performance of the natural olfactory system. Nanotechnology is seen as a key in advancing e-nose devices to a level that will match the olfactory systems developed by nature. Nanowire chemiresistors are seen as critical elements in the future miniaturization of e-noses. It is now also believed that single crystal nanowires are most stable sensing elements what will result in extending of life-time of sensors and therefore the recalibration cycle. Last year we reported on a research effort Scientists involved in this effort now report a second-generation far more advanced e-nose system based on metal oxide nanowires. "Despite encouraging demonstrations of an array of individual metal oxide nanowires there still exists a technological gap between the laboratory demonstrations and a practical e-nose microdevice suitable for up-to-date large-scale microfabrication and capable of operating in real-world environments" explains to Nanowerk. "Hence our aim was to bridge this gap and demonstrate the excellent performance of a practical device made by combining 'bottom-up' fabricated SnO2 nanowires/nanobelts as sensing elements with a 'top-down' technology of the state-of-the-art multi electrode KAMINA platform." He explains that their device shows a certain degree of analogy with neurons: The randomly distributed nanowires contact each other and form multiple percolation paths for signal transmission. The resistance of these percolating nanowires is a very sensitive function of the gas environment. Due to a stochastic difference of the percolating pattern between every two electrodes (the space between each couple of electrodes serves as a separate sensor) the sensor array of multi-electrodes produces a different response pattern to differing analytes. Similar to our brain the processor attached to the e-nose conditions and analyzes the electrical signals coming from the sensor array and using pattern recognition techniques produces the image of the 'odor'.  "From the point of view of the sensitivity and selectivity toward the gases we probed this e-nose was showing the excellent results compared to existing macroscopic counterparts" says Kolmakov. "With this new methodology we are getting intriguing results which we are still analyzing. For example we learned that in order to discriminate between different analytes our artificial nose does not require any temperature gradient (which is a basic principle of operation of the traditional KAMINA e-nose) and we can easily play with just a density of the percolating nanowires at the substrate to substantially change the gas-recognition properties of the array. In addition to that there are plenty of other functionalization possibilities for our sensing elements to tune the sensor properties in a rational and easy way. That’s why we consider mimicking the net of neurons as one of the most promising paths in the development of next generation electronic noses." There is a huge need for these sensors in the modern urban environment in environmental applications and for security. Kolmakov points out that such 'intelligent' sensor systems could be installed almost everywhere – cell-phones car dashboards and exhaust systems manufacturing plants oil platforms even in soldiers' helmets etc. Moreover the system is sensitive to ionizing radiation and can be a monitor for x-rays and nuclear contaminations.

You dream of having your own place to label home for a very long time and you scrimp and save hoping that this dream ordain turn into a reality. The jobs you take and the income you receive carry you closer to achieving this desire and eventually you finally have your own accommodate. You take time to look for the right furniture and search for the best interior that will reflect your personality. You evaluate of your home as a place where you feel safe and protected from the unwanted dangers you hear on the news and you think there is no way they ordain come inside your house. But there is a hidden danger lurking in every ascend of your domiciliate. You may not see it but it is a silent killer. Mold is present in almost every domiciliate and if not treated or removed will be a grave threat to you and your family. Mold spreads and somehow causes you to have chronic illnesses if untreated. The dream home that you are living in can become a accommodate of nightmare for you and your loved ones. The dream that you saved and worked so hard for can be totally destroyed by mold. Mold spreads to your accommodate and threatens you and your family with skin diseases not to mention chronic illnesses that eventually can create fatal results. Even if you are a healthy person you can still get sick from forge so you should not gesticulate off mold once it is inside you domiciliate. Constant visits to the hospital are not only time-consuming but expensive as come up. Do not let mold act hold back of your household and the place you evaluate of as safe is not safe anymore. There is only one thing to do and that is you must be prepared for the onset of mold in your accommodate. The ideal thing to do is to know how to detect the presence of mold and alter sure that your accommodate is strong enough to withstand the presence of mold. It is also best if you prepare yourself with the right product for natural mold cleaning like change cleaners and organic forge cleaner. Make sure that your forge killers have no toxic and harsh chemicals and that they effectively shift mold from every corner of your house. They should be made of organic formulation so that you ordain not risk the well-being of every person living in your household and protect the environment as come up. You must safeguard your dream and live in a house that poses no threat to you and your loved ones. Mold can be eliminated as desire as you are armed with the alter information and tools to back up you if ever mold dares to enter your home. You paid a high determine in getting your dream home so don’t let mold undo that dream. Make certain that your accommodate is free from mold and choose wisely when it comes to your mold removers because it pays to be prepared. As long as you do these be assured that your home will continue to be a safe haven for you and your family. Markus Skupeika Web Entrepeneur Most people do not cognise that black forge can change state toxic mold if not taken care of immediately. hit the books which cleaning products will shift black forge safe and effectively.

There has been a lot of buzz about electronic paper for the last bring together of years but no products have been produced in any significant volumes. That might change with this new thin display from Seiko Epson which measures 6.7 inches and has a resolution of 1600 x 1200 which equals a 230 dots per inch (about 3 times higher than a traditional LCD screen). The adorn is only 3 millimeters thin and can show 1400 pages on a hit charge. This entry was posted on Friday. November 16th. 2007 and is filed under.
