Green Technology

Recovering valuable metals from electronic waste, mining streams and industrial waste typically requires large quantities of chemical reagents. Researchers at the University of Illinois Urbana-Champaign have developed a new molecule that could replace much of […]

Photovoltaic panels generate electricity, solar thermal collectors provide heat, while cooling is usually supplied by air conditioning systems that themselves consume electricity. As a result, buildings require different technologies competing for the limited space available […]

For centuries, useful metals have been developed by starting with one core element and adding small amounts of other elements. Steel, for example, is composed primarily of iron; carbon is added in varied amounts to […]

The moment a nuclear reactor begins operation, a complex chain of events is initiated within the fuel: Heavy atoms split into fission products, knocking other atoms out of place and creating defects that can change […]

The world’s rapid shift to solar power is creating a massive new waste problem, with up to 402 million tonnes (443 million tons) of discarded solar panels projected to accumulate globally by 2060, according to […]

Magnesium supplements are gaining popularity to treat conditions such as insomnia, migraines and constipation. Most magnesium salts are extracted from rocks by crushing and heating them, which requires a lot of energy. Now, researchers reporting […]

AI data centers get a bad rap, not least because of concerns that they drive climate change by consuming massive amounts of electricity. But one potentially larger impact of AI on global carbon emissions may […]

As the world searches for sources of low-emission energy, researchers at Edith Cowan University (ECU) have uncovered a potential clean energy game-changer beneath Western Australia’s red soil. The new study has revealed a way to […]

Smartwatches, phones and even some drones rely on lightweight, rechargeable energy storage systems. Once those devices wear out, many end up as electronic waste. Now, researchers reporting in ACS Energy Letters have developed a compact […]

Cement is one of the most in-demand building materials of our time. Every year, around 4 billion tonnes are produced. Cement production is energy-intensive, and greenhouse gases are emitted during the process—particularly during the thermal […]
