Ammonia, a carbon-free resource can be split into nitrogen and hydrogen gas with the help of metal catalysts like Nickel (Ni). However, these reactions often require very high operating temperatures. Now scientists have developed a highly efficient calcium imide (CaNH)-supported Ni catalyst that can decompose ammonia at temperatures 100°C lower than what conventional Ni catalysts require. This promising new catalyst can get us closer to sustainably producing hydrogen fuel.

The current global climate emergency and our rapidly receding energy resources have people looking out for cleaner alternatives like hydrogen fuel. When burnt in the presence of oxygen, hydrogen gas generates huge amounts of energy but none of the harmful greenhouse gases, unlike fossil fuels...

In the search for sustainable energy storage, researchers at Chalmers University of Technology, Sweden, present a new concept to fabricate high-performance electrode materials for sodium batteries...

Scientists have harnessed the natural ability of wood to faintly glow to develop a new sustainable phosphorescent material that could potentially be used in a wide number of applications, from medical imaging and optical sensing to ‘glow in the dark’ dyes and paints.

An international team of researchers led by North East Forestry University (China) and the University of Bath (UK) investigated the natural phosphorescent properties of lignin, a major component of wood.

Room-temperature phosphorescence (RTP) is when a material absorbs energy with a short wavelength (such as UV light) and then emits it as visible light...

The sale of electric vehicles (EVs) has grown exponentially in the past few years as has the need for renewable energy sources to power them, such as solar and wind. There were nearly 1.8 million registered electric vehicles in the U.S. as of 2020, which is more than three times as many in 2016, according to the International Energy Agency (IEA).

Electric vehicles require power to be available anywhere and anytime, without delays in recharging, but solar and wind are intermittent energy sources that are not available on demand. And the electricity they do generate needs to be stored for later use and not go to waste. That’s where Dr...
