Manifesting the unique properties of carbon nanotubes (CNTs), increasing attention has been paid to the use of single-walled CNTs as a promising electrode material. Therefore, CNT paste electrodes prepared by thoroughly mixing single-walled CNTs and minerals have been seen in a number of instances....More>>

In April 2007, a gasoline tanker crashed and burned while negotiating the MacArthur Maze, a network of interstate connections around the San Francisco/Oakland Bay Bridge in California. The resulting blaze was so intense that it caused parts of the I-580 overpass to crash onto the interstate below.More>>

People have been trying to predict earthquakes for centuries-using animal behavior, weather, and seismic monitoring-but have had less than stellar success. As the human population shifts from a mostly rural existence to a mostly urban one, earthquakes exact a higher price, both in property damage...More>>

One of the worst parts of being stuck in traffic (besides the frustration and the need to watch the cars around you lest one of them do something stupid and dangerous) is the smell. The fumes you can smell are bad enough, but the real nasties are, too often, chemicals that have no scent at all,...More>>

If you haven't spent much time around agricultural equipment, you may not know that modern tractors are very large, very powerful, and increasingly sophisticated to handle the rough terrain and other conditions they deal with every day.More>>

Toxic pollutants have always been a source of concern to the health of aquatic bodies. Ranging from the release of chemicals to oil spills, the effect of such events, particularly in terms of their impact on the population of aquatic species, have alerted us of the degree of harm they can have on...More>>

If you've ever worked while resting a laptop computer on your lap, you know that computers emit heat, and the more powerful the computer, the greater the heat produced. This is a problem because electronics really don't enjoy elevated temperatures. A hot computer is a slow computer or, worse, a...More>>

Electric trains draw power from overhead lines, using a device called a pantograph to maintain connection between the train and the load-carrying wire overhead (known as overhead track equipment (OHTE)).More>>

Many current devices for a continuous monitoring of blood glucose levels are based on direct analysis of blood withdrawn from the tip of a finger. This is disliked by many patients since the finger sticks are painful. Therefore, the goal of more advanced glucose sensing approaches is to minimize...More>>

While GPS can tell ocean-going vessels where they are, the ships rely on propeller speed to figure out how fast they're going. For vessels with fixed propellers, the best way to determine this is to measure the speed of the propeller shaft, which is coupled to the engine.More>>
