Materials

Researchers at UC Berkeley have invented a material in powder form that adsorbs carbon dioxide with astonishing performance. Just 200 g (a little under 0.5 lb) can suck up 44 lb (20 kg) of CO2, the same as a tree does in a year.

Researchers at MIT have unexpectedly stumbled upon a way to 3D print active electronics – meaning transistors and components for controlling electrical signals – without the use of semiconductors or even special fabrication technology.

A new type of carbon-neutral concrete has been commercially used for the first time, in a skyscraper being built in Manhattan. The binder utilized in the concrete is made of granite instead of traditional greenhouse-gas-emitting limestone cement.

While clay is widely used to build basic structures such as huts, we typically don't see it being utilized in large-scale construction projects. That could soon change, however, thanks to a recently developed process known as impact printing.

Scientists have demonstrated a new potential treatment for bone cancer. A bioactive glass laced with a toxic metal was able to kill up to 99% of the cancer without harming healthy cells, and could even help regrow healthy bone after.

Although wind turbines generate electricity via an eco-friendly process, their blades end up in landfills once they wear out. That could change, however, thanks to a resin that would allow old blades to be broken down and recycled into new ones.

Metalworking usually requires very high heat and pressure, but scientists in Singapore have now demonstrated a way to make very pure metal structures at room temperature. It’s inspired by the exoskeletons of crabs and insects.

The 3D printing of certain items could soon get a lot faster, simpler and more eco-friendly. That's because scientists have developed a new 3D printing ink which is easily extruded as a liquid, then solidifies on contact with a saltwater solution.

It’s ironic that while many regions struggle with water shortages, there’s heaps of the stuff floating around in the air everywhere. A new MIT water harvester design can pull enough fresh water out of the air to meet the daily needs of several people.

Your boots may soon have a tropical touch, with a breakthrough in using pineapple leaves to make a strong, 100% natural, sustainable leather. It comprehensively outperformed mushroom leather, and has serious potential for scalable, commercial use.

If you think these bricks look so simple even a robot could build a house with them, you'd be right. Plaex, the startup behind them, sees an automated construction industry in our near future, where materials will adapt to suit a new robotic workforce.

Forget radioactive spiders – a new breakthrough could make it easier to get Spider-Man’s wall-crawling powers. Scientists in Singapore have created a strong and reusable adhesive out of a shape-memory polymer, triggered by temperature changes.
