Glass

Scientists have created the world’s smallest wine glass, narrower than a human hair. Made out of actual glass, the model is a test run of a new 3D-printing process that could help make nanoscale glass components for electronic and optical devices.

While glass bricks are effective for allowing daylight into buildings, they're not good insulators and they can't be used for entire load-bearing walls. Such is reportedly not the case, however, with experimental new aerogel-filled translucent bricks.

The next World Expo fair won't begin until 2025, but initial architectural designs are already being revealed. This attractive example will consist of a top-heavy spiraling structure that pays homage to the Czech Republic's glassmaking tradition.
-
Most three-dimensional glass objects are produced via either a molding, blowing or 3D-printing process. Chinese scientists, however, have devised a technique of folding such items into shape – and it has some key advantages over other methods.
-
Even though glass is praised for being fully recyclable, the EPA states that only about a third of discarded glass items actually get recycled. With that problem in mind, scientists have developed a new type of glass which is biodegradable.
-
Although glass is known for being fully recyclable, the US Environmental Protection Agency states that only about one third of post-consumer glass actually gets recycled. A new glass-based building cladding material could help boost that number.
-
A lot of glass houses aren't really built with practicality or comfort in mind, but Casa Annunziata is different. The luxury home features a stylish modernist design that offers the benefits of lots of glass, while addressing some of the drawbacks.
-
Solar panels can’t operate efficiently if they’re caked in dirt, but cleaning them regularly can be a time-consuming process. Engineers in Germany have now developed an ultra-thin coating that can make solar panels and other surfaces self-cleaning.
-
After the summer so many of us have just sweltered through, we need better ways to cool buildings. Researchers have now spruced up the humble window with hydrogel-glass, which can selectively block heat from the Sun without blocking its light.
-
Concrete is a popular building material, enough so that one of its key ingredients – sand – is in short supply. Scientists are thus now exploring the possibility of replacing that sand with glass waste that would otherwise end up in landfills.
-
Robots and other automated systems have always had trouble visually gauging the 3D shape of transparent objects, like those made of glass. A new system addresses that problem, by using a laser to quickly heat such items.
-
For some time now, antimicrobial bioactive glass has been put forward for use in applications such as medical implants, hospital surfaces and wound dressings. Now, scientists report they have boosted its bacteria-killing effect by over 100 times.
