Feeding plants to this algae could fuel your car
18 Jul 2018 at 7:48am
The research shows that a freshwater production strain of microalgae, Auxenochlorella protothecoides, is capable of directly degrading and utilizing non-food plant substrates, such as switchgrass, for improved cell growth and lipid productivity, useful for boosting the algae's potential value as a biofuel.
How to build efficient organic solar cells
16 Jul 2018 at 8:45am
Twenty-five researchers from seven research institutes have put their heads together to draw up rules for designing high-efficiency organic solar cells.
New tool to calculate 'nitrogen footprint' offers guide to pollution reduction
16 Jul 2018 at 7:31am
Researchers have helped create the first tool to calculate the 'nitrogen footprint' of an organization. The tool will provide a guide to sustainability and pollution reduction for daily activities such as food consumption, travel and energy use.
How gold nanoparticles could improve solar energy storage
12 Jul 2018 at 8:45am
Star-shaped gold nanoparticles, coated with a semiconductor, can produce hydrogen from water over four times more efficiently than other methods - opening the door to improved storage of solar energy and other advances that could boost renewable energy use and combat climate change, according to researchers.
Bacteria-powered solar cell converts light to energy, even under overcast skies
5 Jul 2018 at 5:42am
Researchers have found a cheap, sustainable way to build a solar cell using bacteria that convert light to energy. Their cell generated a current stronger than any previously recorded from such a device, and worked as efficiently in dim light as in bright light. This innovation could be a step toward wider adoption of solar power in places like British Columbia and parts of northern Europe where overcast skies are common.
In a warming world, could air conditioning make things worse?
3 Jul 2018 at 11:14am
As climate change continues to push summer temperatures ever higher, the increased use of air conditioning in buildings could add to the problems of a warming world by further degrading air quality and compounding the toll of air pollution on human health, according to a new study.
Diesel doesn't float this boat
3 Jul 2018 at 7:59am
Marine research could soon be possible without the risk of polluting either the air or the ocean, thanks to a new ship design and feasibility study.
The vanishing nuclear industry
2 Jul 2018 at 12:47pm
Could nuclear power make a significant contribution to decarbonizing the US energy system over the next three or four decades? Probably not.
Artificial intelligence accurately predicts distribution of radioactive fallout
2 Jul 2018 at 6:40am
Researchers have created a machine-learning-based tool that can predict where radioactive emissions from nuclear power plants will disperse. After training using extensive data on previous weather patterns, the tool consistently achieved over 85 percent predictive accuracy, and up to 95 percent in winter when large and predictable weather systems dominate. This tool can aid immediate evacuation in the aftermath of disasters like those at Fukushima and Chernobyl.
Carbon dioxide-to-methanol process improved by catalyst
28 Jun 2018 at 2:14pm
Dramatic improvements have been made to the process of converting carbon dioxide, a greenhouse gas, to methanol, a fuel and building block for a wide range of everyday materials, according to researchers.
Path to zero emissions starts out easy, but gets steep
28 Jun 2018 at 12:18pm
Carbon dioxide emissions from human activities must approach zero within several decades to avoid risking grave damage from the effects of climate change. This will require creativity and innovation, because some types of industrial sources of atmospheric carbon lack affordable emissions-free substitutes, according to a new article.
Finding the right balance for catalysts in the hydrogen evolution reaction
27 Jun 2018 at 1:04pm
A collaboration has optimized the balance between the catalytic activity in hydrogen generation and stability of metal nanoparticles coated with different numbers of graphene layers. The team found that coating the catalyst nanoparticles with three to five graphene layers provided samples that displayed high catalytic activity in hydrogen evolution as well as high stability in acidic solution. These findings should aid the development of economical processes for large-scale hydrogen production.
A milestone on the path towards efficient solar cells: Singlet fission
27 Jun 2018 at 1:03pm
Generating more electricity from solar cells and conducting further research into so-called singlet fission. Singlet fission could considerably boost the efficiency of solar cells -- and thanks to the latest research it is one step closer to becoming possible.
'Electrogeochemistry' captures carbon, produces fuel, offsets ocean acidifica...
25 Jun 2018 at 4:28pm
Limiting global warming to 2 degrees Celsius will require not only reducing emissions of carbon dioxide, but also active removal of carbon dioxide from the atmosphere. This has prompted heightened interest in 'negative emissions technologies.' A new study evaluates the potential for recently described methods that capture carbon dioxide from the atmosphere through an 'electrogeochemical' process that also generates hydrogen gas for use as fuel and creates by-products that can help counteract ocean acidification.
