Space Mining: One Step Closer To Becoming A Reality

Mining an asteroid may sound like something out of a science fiction movie, mainly because there have been so many movies based around this exact subject. But today, space mining is taking one step closer to becoming a reality. The Space Act of 2015 has just passed in Congress allowing commercial exploration and recovery of space resources.  Last week the act passed through the Senate and is now ...

Drones: Taking Mining To New Heights

Different industries from all over the world are experimenting with creative ways to use drones to increase their productivity and efficiency.  Even industries you wouldn't expect to use drones are finding amazing ways to make this technology work for them. Mining is just one of the many sectors that have adopted this new technology and have seen the benefits drones can bring. Miners are ...

Steel Is Getting A Make Over

Steel has long been one of the most common and reliable building materials for hundreds of years, so it may seem strange to be talking about a recent steel breakthrough. But recently a discovery surrounding this centuries old building material has just come to fruition. Researchers at Pohang University of Science and Technology in South Korea have just brought steel into the 21st century by ...

New Developments in Graphene Manufacturing

Producing Graphene Is Now Cheaper and Easier Than Ever Before     A revolutionary new way to manufacture the wonder material Graphene has been developed by researchers from the University of Exeter. This innovative new method of production is significantly cheaper and less complex then previous methods. The team led by Professor Monica Craciun is using this new technique to develop ...

US scientists create ‘friction-free’ material

Scientists at the US Department of Energy’s Argonne National Laboratory have found a way to use diamonds and graphene to create a new material combination that demonstrates so-called superlubricity. Led by nanoscientist Ani Sumant of Argonne’s Center for Nanoscale Materials (CNM) and Argonne Distinguished Fellow Ali Erdemir of Argonne’s Energy Systems Division, the Argonne team combined ...

The Mystery of the Brand-New Bay Bridge’s Corroded Steel

Plink goes the pendulum arm as it smashes into a 3-inch section of steel. The sound is high-pitched, which tells any metallurgist with a good ear that the piece is brittle. The arm is the business end of a Charpy impact tester—it swings into a thing and, on impact, measures how much energy it took to break that thing. In this case, the thing is steel from a new bridge connecting two cities in ...

Aluminum Battery Charges in 1 Minute

Lithium-ion batteries have been a boon for the modern world -- they've replaced the heavier, single-use alkaline type in everything from wristwatches to jumbo jets. Unfortunately, these rechargeable cells are already struggling to keep up with our ever-increasing energy needs. But a new type of aluminum-ion battery developed at Stanford University is not only less explode-y than lithium, but ...

Watching alloys change from liquid to solid could lead to better metals

If you put a camera in the ice machine and watched water turn into ice, the process would look simple. But the mechanism behind liquids turning to solids is actually quite complex, and understanding it better could improve design and production of metals. A recent investigation aboard the International Space Station contributed to that understanding. A series of experiments conducted in the ...

New Titanium-Making Process Could Result in Lighter Aircraft

Titanium is often used where low weight and high strength are required and money is no object—because it's extremely costly to produce. Now, a new manufacturing technique could reduce the expense, and make the material as useful for cars as it is for fighter jets. Titanium is usually made using the Kroll process. It takes refined rutile or ilmenite from the original metal ore, then puts its ...

New Steel Alloy Stronger Than Titanium

Big news from the metallurgy desk this week: It looks like steel is about to get a lot steelier. According to a report published today in the prestigious journal Nature, researchers in South Korea have developed a new recipe for making a high-strength, low-density steel alloy that can outperform titanium in terms of strength and ductility. In materials science, ductility is a measure of a ...
