On the road to conductors of the future

Superconductivity in hydrogen sulfide

16-Sep-2020

Superconducting wires can transport electricity without loss. This would allow for less power production, reducing both costs and greenhouse gasses. Unfortunately, extensive cooling stands in the way, because existing superconductors only lose their resistance at extremely low temperatures. In ...

Self-healing electronics out of living cells?

Shock to bacteria activates nature's electrical grid

19-Aug-2020

The ocean floor and the ground beneath our feet are riddled with tiny nanowires -- 1/100,000th the width of a human hair -- created by billions of bacteria that can generate electric currents from organic waste. In new research published Aug. 17 in the journal Nature Chemical Biology, Yale ...

Researchers design efficient low-cost system for producing power at night

Rooftop radiative cooling system could provide lighting power when solar energy is unavailable

18-Aug-2020

Researchers have designed an off-grid, low-cost modular energy source that can efficiently produce power at night. The system uses commercially available technology and could eventually help meet the need for nighttime lighting in urban areas or provide lighting in developing countries. Although ...

Engineers use electricity to clean up toxic water

Powerful electrochemical process destroys water contaminants, such as pesticides

10-Jul-2020

A team of engineers may be one step closer to cleaning up heavily contaminated industrial wastewater streams. Researchers from the School of Chemical and Biomolecular Engineering developed an electrochemical oxidation process with the aim of cleaning up complex wastewater that contained a toxic ...

Using the ‘shadow-effect’ to generate electricity

Novel shadow-effect energy generator uses the contrast in illumination between the lit and shadowed areas

25-May-2020

Shadows are often associated with darkness and uncertainty. Now, researchers from the National University of Singapore (NUS) are giving shadows a positive spin by demonstrating a way to harness this common but often overlooked optical effect to generate electricity. This novel concept opens up ...

Innovative thinner electrolyte can improve functioning of solid oxide fuel cells

Scientists have synthesized a new thin film that could make energy production more efficient and cleaner

27-Mar-2020

In this post-industrialization age, electricity has become the backbone of our society. However, using fossil fuels to generate it is not the best option because of their limited availability and harmful nature. In the last two decades, significant efforts have been made to develop techniques to ...

World's smelliest fruit could charge your mobile phone

Turn tropical fruits into super-capacitors

09-Mar-2020

Imagine if we could use naturally-grown products, like plants and fruit, to store electricity that charges commonly used electronics like mobile phones, tablets, laptops or even electric cars? Researchers from the University of Sydney have done just that, and have developed a method that uses ...

New green technology generates electricity 'out of thin air'

Power generation from ambient humidity using protein nanowires

19-Feb-2020

Scientists at the University of Massachusetts Amherst have developed a device that uses a natural protein to create electricity from moisture in the air, a new technology they say could have significant implications for the future of renewable energy, climate change and in the future of ...

New Material Breaks World Record Turning Heat into Electricity

15-Nov-2019

A new type of material generates electrical current very efficiently from temperature differences. This allows sensors and small processors to supply themselves with energy wirelessly. Thermoelectric materials can convert heat into electrical energy. This is due to the so-called Seebeck effect: ...
