Water pipe-inspection robot designed to have a light touch

By - December 2, 2014 1 Picture
When it comes to robots that perform internal inspections of water pipes, virtually all of them move along on rubber tires or treads. As that rubber grips against the inside of the pipe, however, it dislodges rust particles that ultimately end up coming out of peoples' taps. In an effort to address that problem, the European Union TRACT project is developing a propeller-driven inspection robot that keeps the pipe-touching to a minimum. Read More

Terahertz tech could keep cars from rusting

By - May 21, 2014 1 Picture
Although all steel-bodied cars rust eventually, premature rusting may soon be less of a problem thanks to technology developed by father-and-son team Anis and Aunik Rahman. Their system non-destructively analyzes automobiles' paint jobs, making sure that the layers of paint have been applied properly. It could reportedly also find use diagnosing the early stages of skin cancer. Read More

Military vehicles could soon feature self-healing paint

By - March 19, 2014 1 Picture
According to the US Department of Defense, corrosion costs the Navy approximately US$7 billion every year. That's certainly an incentive for developing a method of keeping military vehicles from rusting. Now, researchers from the Office of Naval Research and The Johns Hopkins University Applied Physics Laboratory may be onto something. They're looking into the use a powder that could allow scratched or chipped paint to "heal like human skin." Read More

Researchers produce hydrogen from sunlight, water and rust

As scientists endeavor to increase the efficiency of solar panels, the challenge of storing the resultant energy cheaply and in an environmentally responsible way must also be met. To this end, researchers at Switzerland’s École polytechnique fédérale de Lausann (EPFL) have developed an inexpensive device that transforms light energy into hydrogen, for storage and later use. The new prototype makes use of sunlight, water, and metal oxides, including iron oxide – or rust. Read More

Graphene used to rust-proof steel

By - May 29, 2012 2 Pictures
Hexavalent chromium compounds are a key ingredient in coatings used to rust-proof steel. They also happen to be carcinogenic. Researchers, therefore, have been looking for non-toxic alternatives that could be used to keep steel items from corroding. Recently, scientists from the University at Buffalo announced that they have developed such a substance. It’s a varnish that incorporates graphene, the one-atom-thick carbon sheeting material that is the thinnest and strongest substance known to exist. Read More

New form of corrosive bacteria found aboard Titanic

By - December 14, 2010 4 Pictures
Misfortune continues to take a bite out of the world's most famous ocean liner – literally. Twenty-five years after the RMS Titanic's ocean grave was discovered a few hundred miles off the coast of Newfoundland, researchers have identified a new bacteria feeding on the great ship's hulk. The scientists believe that the new micro-organism may work with a complex variety of bacteria, which inhabit a microscopic world inside porous mounds of rusty stalactites called rusticles, to break down metal into a fine powder.

Plastic bags keep steel tools from rusting

By - December 2, 2010 1 Picture
Fishermen, sailors, and other people who take to the sea will know how quickly and easily steel tools begin to rust in a marine environment. One method of dealing with the problem involves spraying the tools with oil before storage, then wiping them off before use. New Jersey-based company Leland Limited, however, is now offering what it describes as a simpler, more eco-friendly alternative: plastic tool-storage bags that prevent rust. Read More

Save those cigarette butts, and use them to protect steel

By - May 13, 2010 1 Picture
It has been estimated that every year, 4.5 trillion cigarette butts are added to the world’s ecosystem. That would be bad enough if they were simply disgusting, but when they’re left on beaches or washed down storm sewers, they can be lethal to fish. Unfortunately, there’s nothing that can be done with the butts, other than throwing them out... until now, perhaps. Researchers from China’s Xi’an Jiaotong University claim that cigarette butts can be used to make an excellent rust inhibitor. Read More

New rust sensor could lead to safer bridges

By - April 22, 2010 1 Picture
According to the Neil Young album title, rust never sleeps. In construction, rust damage can be insidious – especially in infrastructure like concrete bridges where rust can have fatal consequences if the steel in bridges fails. But detecting rust before it’s too late has been an ongoing challenge for engineers and scientists. Experts at the Fraunhofer Institute for Microelectronic Circuits and Systems IMS have developed an early-warning system for rust. By installing sensor-transponders into in the concrete to measure the extent of corrosion, engineers are being given a vital heads-up. Read More
