Scientists have devised a novel system that can recognize visual objects by bending light.
These exceptions desert gems were created by a powerful meteorite impact.
You can apply the technique on any existing 3-D printer.
Vitrification is the way to go.
Israel Antiques Authority (IAA) archaeologists have uncovered the ruins of a 1,600 year-old complex of glass kilns in the Jezreel Valley. Their size indicates that Israel was one of the most important glass manufacturing center in the ancient world, says Dr. Yael Gorin-Rosen, IAA’s Glass Department head curator.
Using a newly-developed production method, the Institute of Industrial Science at Tokyo University succeeded in producing a type of glass that rivals steel in hardness. The new material opens huge developmental lanes for any glass and glass-related product, from tableware to bulletproof glass.
A 300 meter long (984 ft) glass suspension bridge, 180 meters (591 ft) above the ground has recently opened in Hunan, part of China’s Shiniuzhai National Geological Park. As if that wasn’t scary enough, the entire thing is made of glass-like material, and it’s transparent. Eloquently named Haohan Qiao or ‘Brave Men’s Bridge’, the bridge is an adventure in itself, as the
What happens when you mix the physical properties of glass (brittle and flowing) and metal (stiff and tough)? You get metal glass, of course. Since the 1960s, scientists showed you can make certain alloys into metal glass by rapidly cooling them. Really, really fast. Hundreds of degrees in a fraction of a second. Eventually you end up with an alloy that both behaves like a metal and glass. Some are three times stronger than titanium and have the elastic modulus of bone, all while being extremely lightweight. They’re also a lot more easy to machine than metals. All in all, metal glass is amazing and has the possibility to transform the world, just like another wonder material: graphene. So, why aren’t we seeing more of it? Part of the problem is that research is moving painfully slow, but this may set to change after a team of researchers in Sydney reported a model for the atomic structure of metal glass. If until now scientists were testing various alloys and technique in the dark, by trial and error, now they have a cook book for metal glass.
A team of researchers has managed to make metallic glasses from pure, monoatomic metals. These metals are amorphous like glass, but they retain some of the properties of metals – like ultrafast cooling and solid state reaction.
Water is liquid, air is gaseous, but glass? For years at end, glass has perplexed scholars intending on fixing it under a state of matter. Neither liquid, nor solid, explaining glass is a lot harder than some might think. Researchers at Duke University have contributed to solving the puzzle after they performed numerical solutions and found the energy landscapes of glasses
What’s the difference between a solid and liquid? You might find this question trivial – naturally, liquids flow and solids… well, they don’t. From a physical point of view, however, things aren’t that simple. Intrigued by some ever so often encountered exceptions in the current accepted theory that describes the differences between the states of matter, scientists have tried to
Aged glasses are materials that interest scientists very much due to their appealing properties. During thousands and even millions of years glass steadily evolves towards an ever stable molecular configuration. In manufacturing where the process needs to be cut short to weeks or days, similar properties are extremely difficult if not at times impossible to reproduce.
