It's estimated that mining, refining, and processing metals commonly used in construction, referred to as structural metals, contribute around three billion tons of CO2-equivalent emissions. And, although recycling these materials has the potential to mitigate their negative environmental impact, many sustain damage, like fractures, that can preclude them from extending Read More
A new method could provide detailed information about internal structures, voids, and cracks, based solely on data about exterior conditions.
Maybe you can’t tell a book from its cover, but according to researchers at MIT you may now be able to do the equivalent for materials of all sorts, from an Read More
What’s in a name? It’s a question we’ve been asking since Shakespearian times. And though the genius concludes that a name does not change the object itself, I’m here to tell you he’s wrong. In a free market, your name means everything. Who goes through life without a name? Infact, Read More
The magnets in wind turbines come from China, and the materials in our electric car batteries are for the most part sourced from Congo. Today, key minerals and metals are being transported to Europe from politically unstable countries far away. Is it possible to safeguard access to these raw materials? Read More
The green hydrogen economy is a sustainable alternative to fossil fuels. However, one of the challenges of constructing a global hydrogen economy is hydrogen transportation by sea. A new paper proposes solid air as a medium for recycling cold energy across the hydrogen liquefaction supply chain.
The world is undergoing an Read More
The global positioning system (GPS) is a network of satellites and receiving devices used to determine the location of something on Earth.
Using the strange quantum phenomenon known as entanglement, which can link particles together anywhere in the universe, sensors can become significantly more accurate and faster at detecting motion, a Read More
National governments should consider mandating real-time indoor air quality monitoring in at least all public buildings, researchers have said.
The University of Hong Kong team studied indoor air quality as it was one of the factors aiding the spread of Covid-19 during the pandemic.
While effective, vaccination has not completely controlled the Read More
Texas state Sen. Kelly Hancock (R) and Brad Jones, the former CEO of the Electric Reliability Council of Texas (ERCOT), sounded the alarm over a plan that would unravel Gov. Greg Abbott’s (R-TX) plan to secure the state electric grid.
Over the last couple of years, Texas public officials have grappled Read More
A team of organic chemists and engineers from Linköping University and KTH Royal Institute of Technology, both in Sweden, has demonstrated that working transistors can be made from treated wood. The results have been published in Proceedings of the National Academy of Sciences.
Transistors are devices that switch or amplify electrical Read More
Hydrogen is an energy-rich gas, which releases no carbon emissions when burned. It can be used in most equipment where fossil fuels such as natural gas (methane) or LPG (liquefied petroleum gas) are currently used. In your home, that might mean a gas boiler, heater, cooker or all three.
It can Read More
