[...] scientists say a simple and inexpensive new process can transform any type of wood into a material stronger than steel, and even some high-tech titanium alloys. [...]

The results are impressive. The team’s compressed wood is three times as dense as the untreated substance, Hu says, adding that its resistance to being ripped apart is increased more than 10-fold. It also can become about 50 times more resistant to compression and almost 20 times as stiff. — Scientific American

Since 2008, Solidia Technologies [...] has been quietly developing a new cement-making process that produces up to 70% fewer CO2 emissions at a cost that DeCristofaro claims is on par with or better than conventional cement.

Solidia, which was formed in a bid to commercialize ideas developed at Rutgers University in New Jersey, is not the first company to attempt to make environmentally friendly cement. But industry experts say it’s the most promising yet. — Quartz

Molecules 10,000 times narrower than the width of a human hair could hold the key to making possible wooden skyscrapers and more energy-efficient paper production, according to research published today in the journal Nature Communications. The study, led by a father and son team at the Universities of Warwick and Cambridge, solves a long-standing mystery of how key sugars in cells bind to form strong, indigestible materials. — University of Cambridge

In bone, the proportions of protein and mineral are roughly equal – the mineral gives bone stiffness and hardness, while the protein gives it toughness or resistance to fracture. While bones can break, it is relatively rare, and they have the benefit of being self-healing [...]

“All of our existing building standards have been designed with concrete and steel in mind. Constructing buildings out of entirely new materials would mean completely rethinking the whole industry." — cam.ac.uk

adding butts can cut the energy needed to fire bricks by up to 58 per cent.

Fired-clay bricks incorporated with cigarette butts were also lighter with better insulation properties – meaning reduced household heating and cooling costs.

Importantly, bricks incorporated with 1 per cent cigarette butts maintained properties very similar to those of normal bricks. — sciencedaily.com

A scientist in Mexico has created glowing cement that absorbs solar energy during the day and emits light after sun-down.

Claiming the engineered cement can last a hundred years, he says it could make roads and structures glow in the dark, cutting the cost of street-lighting.

The patent is the first for Mexico’s University of San Nicolas Hidalgo, says the researcher behind the invention, Dr. José Carlos Rubio, according to Investigación y Desarrollo. — globalconstructionreview.com

Glue is the future of architecture. At least that’s how architect Greg Lynn sees it. And he’s not alone. “Mechanical assembly is already waning in many industries,” Lynn says. “An airplane now is glued together. A car now is glued together. Even a lot of appliances are being glued together.” So why not skyscrapers? — New Scientist

Researchers at University College London (UCL) claim that a “revolutionary” new type of window could cut cleaning costs in tall buildings and reduce heating bills by up to 40% thanks to a new combination of nano-scale engineering inspired by the eyes of moths, and thermochromic coating.

The prototype, revealed today, has conical nanostructures engraved on its surface that trap air and prevent all but a tiny amount of water coming into actual contact with the glass. — globalconstructionreview.com

According to a team of researchers at MIT, both scenarios may be possible before long, thanks to a new material that can store solar energy during the day and release it later as heat, whenever it’s needed. This transparent polymer film could be applied to many different surfaces, such as window glass or clothing.

[...] the new finding could provide a highly efficient method for storing the sun’s energy through a chemical reaction and releasing it later as heat. — news.mit.edu

This relatively low-tech method is among a battery of tests that materials scientists are using to determine why several anchor rods securing the newest portion of the San Francisco Bay Bridge, the region’s busiest, failed their earthquake inspections. The first alarms sounded in 2013, when seismic tests found 32 faulty rods. They’d been sitting in a large pool of water, corroding. — wired.com

The downside of giant banks of windows or glass walls, though, becomes obvious when the relentless afternoon sun makes the heat and stuffiness inside intolerable [...].

The makers of “smart glass” say they can address this problem. Smart-glass windows transform from transparent to opaque, and every shade in between, in seconds. They often rely on electrochromic thin films embedded in the glass.

The upshot: Less energy is needed to heat or cool a building. Shades and blinds become optional. — qz.com

A project from three students at Barcelona’s Institute for Advanced Architecture of Catalunya continues that exploration by looking at how physical spaces could someday morph based on various environmental inputs.

The project, Translated Geometries, tackles the idea by developing a new use for Shape Memory Polymers, a composite material that can deform and return to its original state when activated by cues like heat, humidity and light. — wired.com

Every piece of garbage can be turned into raw material that can be used in future products. With his influential Cradle to Cradle movement, Germany's Michael Braungart espouses a form of eco-hedonism that puts smart production before conservation. — spiegel.de
