We may not yet have the liquid metal depicted in the Terminator movies, but scientists have now developed something that’s vaguely along the same lines. German materials scientist Dr. Jörg Weißmüller and Chinese research scientist Hai-Jun Jin have created a metallic material that can change back and forth between being strong but brittle and soft but malleable, via electrical signals.  Read More

What do you do if you want a material that’s as hard as glass, but that can bend without shattering, like steel? Well, if you’re a researcher at the California Institute of Technology (Caltech), you invent metallic glass. There are several types of metallic glass – which is said to be stronger than steel or titanium – all of which consist of a metal with the disordered atomic structure of glass. Although it’s been possible to produce the material in bulk since the early 90s, the production process has limitations, that have kept metallic glass from coming into common use. Now, however, a Caltech team has come up with a new process, in which the material can be shaped as easily as plastic.  Read More

Cigarette butts contain chemicals that may keep steel from rusting

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

The Mosquito electric bike

With a very sturdy folded steel frame and elegant simple design, the Mosquito or Mücke electric bike is one good-looking machine. Its 48V lithium batteries only cost a few (European) cents to charge up and will give a range of about 60km (37 miles). The 0.8kW motor produces a top speed of around 50km/h (31mph) and the bike also has a removable center pole for instant accessibility.  Read More

Stainless steel baby bottles offer a safer, more durable alternative to plastic or glass b...

Given the concerns and controversy about plastic baby bottles containing bisphenol A (BPA) and other toxins, it was only a matter of time that an alternative product was sourced to manufacture baby bottles. OrganicKidz stainless steel baby bottles are free from BPA, PVC and Phtalates and are durable, unbreakable and 100% recyclable.  Read More

Metaklett steel hook-and-loop fastener

A new material called Metaklett is like hook-and-loop (“Velcro”) made out of steel and much scarier. One side of the material bristles with sharp spikes and the other side has jagged steel brushes. Looking something like the mouth of a prehistoric shark, a square meter of Metaklett can support up to 35 metric tons and withstand heat of up to 800 degrees Celsius. Developed at the Technical University of Munich, Germany, researchers borrowed from the traditional hook-and-loop concept to design a fastener for extreme loads and environments such as automotive, building, or military applications.  Read More
