Posted by: Kevin Permalink Source New Method For Water-purification
With the new aerobic granular sludge technology (Nereda TM), aerobic (thus oxygen using) bacterial granules are formed in the water that is to be purified. The great advantage of these granules is that they sink quickly and that all the mandatory biological purifying processes occur within these granules. The technology therefore offers important advantages when compared to conventional water purification processes. For example, all the processes can occur in one reactor. Moreover, there is no need to use large re-sinking tanks, such as those used for conventional purification. Such large tanks are needed for this because the bacteria clusters that are formed take much longer to sink than the aerobic granule sludge. As per Delft PhD researcher Merle de Kreuk, a Nereda TM purification installation needs only a quarter of the space mandatory by conventional installations. Moreover, Nereda TM uses 30% less energy than the normal purification process. This Nereda TM purification process is suitable for both domestic and industrial waste water.........

What's to stop attacks on America's power lines? An Iowa State University research team led by Arun Somani, chair and Jerry R. Junkins professor of electrical and computer engineering, is working to develop a network of wireless sensors that could monitor the country's electricity transmission system. While the sensors could pick up suspicious activity at power poles, they'd be particularly useful at quickly locating any breakdowns. That could allow power companies to react in time to prevent power disruptions from cascading into blackouts. And the monitoring system could also help power companies quickly locate problems when severe weather tears down electrical lines. With networks of sensors, "Power companies would have additional abilities to view their systems and that would assist in disaster recovery," Somani said. America has a lot of transmission lines, substations and generators that could use some monitoring. The Department of Energy reported the country had 157,810 miles of transmission lines in 2004. And the department reported that America's power plants produced 3.97 billion megawatt hours of electricity in 2004. The monitoring system depends on sensors housed in black boxes just a few inches across. Somani recently picked up one of the sensors inside Iowa State's Wireless and Sensor Networking Laboratory and showed off the electronics capable of watching out for conductor failures, tower collapses, hot spots and other extreme conditions. A tiny camera can also be mounted in the sensor to look for suspicious movements around power lines......... Posted by: Tom Permalink Source Diamond As A By-Product
"The idea we explored was based on ball milling graphite processes found in the hydrogen storage literature," said Angela D. Lueking, assistant professor of energy and geoenvironmental engineering. "We substituted anthracite coal for graphite because it is abundant and inexpensive. Now, with 20/20 hindsight, we are struck by the fact that coal gasification is currently the most economical way to produce hydrogen." Interest in hydrogen as a vehicular fuel has a number of scientists investigating ways to create hydrogen inexpensively; other scientists are looking at ways to transport and store hydrogen in a safe manner. Lueking's group was exploring a way to store hydrogen in carbon-based materials, and inadvertently stumbled upon a method that combines production and storage and produces nanocrystalline diamonds as a by-product. Lueking and his colleagues, who included Humberto R. Gutierrez, post doctoral fellow in physics; Dania A Fonseca, post doctoral fellow in the Penn State Energy Institute; Deepa L. Narayanan, Dirk Van Essendelft and Puja Jain, graduate students in energy and geoenvironmental engineering and Caroline E. B. Clifford, research associate, Energy Institute, ball milled powdered anthracite coal with cyclohexene. Ball milling involves mixing a slurry of anthracite powder and cyclohexene with small steel balls and mixing so that the steel balls pound the coal particles and the cyclohexene causing physical and chemical changes. The scientists reported their results in a recent online issue of the Journal of the American Chemical Society......... Posted by: Kevin Permalink Source First Method To Sort Nanotubes By Size
Nanotubes, tiny cylinders of carbon no wider than a strand of DNA, possess a tantalizing array of properties coveted by materials scientists. Nanotubes are stronger than steel, but weigh one sixth as much. Some varieties are excellent semiconductors, while others are metals that conduct electricity as well as copper. But there are dozens of varieties of nanotubes, each slightly different in size and atomic structure and each with very different properties. For a number of applications, engineers need to use just one type of nanotube, but that's not possible today because all production methods turn out a mishmash of types. New research due to appear in an upcoming issue of the Journal of the American Chemical Society describes a new method that uses electric fields to sort nanotubes by size. "People have developed sorting methods based on both chemical and electrical properties, but ours is the first that's capable of sorting semiconducting nanotubes based upon their dielectric constant, which is determined by their diameter," said corresponding author, Howard Schmidt, executive director of Rice's Carbon Nanotechnology Laboratory (CNL)......... Posted by: Kevin Permalink Source Microchannels Aid Drug Discovery
The tool breaks down cell membranes to allow drug and gene delivery and permits examination of intracellular materials by establishing an electrical current across a microscale channel, said Chang Lu, a Purdue University biological engineer. The Purdue system is different from current techniques that use electricity for drug delivery and cell analysis. The new technique handles one cell at a time and uses a common DC power supply rather than a costly pulse generator. "Normally when you do testing, you need a lot of cells, and the properties that you record are the average of that cell population," Lu said. "If you carry out the test based on single cells, you have access to a more detailed picture of the cell population and can pinpoint abnormalities more quickly and exactly". The size of the channel, while small enough to accommodate only one cell at its narrowest diameter, varies in width so that the electric field intensity differs depending on the cell's location in the device, Lu said. The flow rate controls how much time the cell spends in the high electrical field, where a process called electroporation occurs. Controlling the length of time in the high electrical field without turning the voltage on and off helps maintain the cell's viability.........

Knowing how fuel cells work is key to improving their performance and reducing the cost of their production. Now a research team led by Scott A. Barnett, professor of materials science and engineering at Northwestern University, has produced the first three-dimensional images of the interior of a fuel cell -- providing a new tool for the study and development of fuel cells. The researchers' three-dimensional reconstruction of a solid oxide fuel cell anode was reported in a paper published this month by the journal Nature Materials. (A solid oxide fuel cell efficiently converts fuels such as hydrogen and natural gas directly into electricity; Barnett's group also recently reported a similar fuel cell that works with a liquid transportation fuel -- iso-octane, a high-purity compound similar to gasoline.) "Much like magnetic resonance imaging produces a view inside the human body, we now can look inside fuel cells," said Barnett. "The dual-beam focused-ion-beam microscope used in the study provides much higher resolution than an MRI, showing nanometer-scale features. These pictures will help us and other scientists to unravel how fuel cells work so they can eventually be improved and made to work longer without failing.".........
